[0016] The objective of this invention is to provide a filtration unit of the type described at the beginning, which is capable of effective cleaning operation on surfaces made of textile materials.

[0017] The task is solved in the filter unit described at the beginning according to the invention in such a way that the filter unit can be positioned as a whole on the cleaning machine and can be removed as a whole from the cleaning machine, is provided with a housing, and is provided with at least one first filter and a second filter, wherein the first filter and the second filter are arranged on the housing, the first filter is a pre-filter of the second filter, and the first filter is configured as a lint filter.

[0018] It has been shown that the lint from textile materials can easily clog the main filter (secondary filter). If, for example, a HEPA filter is used as the main filter, purification may only be achieved with considerable effort.

[0019] Effective cleaning is achieved by placing the lint filter (first filter) upstream of the main filter (second filter). The first filter can thus also achieve purification with relatively low structural costs.

[0020] The filter unit is constructed as a filter cartridge or filter box and can therefore be processed as a whole.

[0021] Specifically, set at least one of the following:

[0022] - The first filter is designed to filter out particles with a size of at least 100 μm, especially at least 150 μm, especially at least 200 μm and especially at least 250 μm;

[0023] - The first filter includes a coil structure and, in particular, a screen fabric or non-woven fabric;

[0024] - The first filter is made of metal.

[0025] - The first filter includes a surface filter medium;

[0026] -The first filter is configured to allow it to be mechanically purified;

[0027] - The first filter has a surface that is at least approximately square or rectangular in shape;

[0028] - The first filter has a maximum height of 5cm;

[0029] - The first filter can be removed from the housing.

[0030] The appropriate size of the first filter can preferably filter out fluff particles, especially those with a size of at least 200 μm, and thus prevent them from being blocked by the second filter.

[0031] This can be achieved efficiently if the first filter contains a coil structure with a corresponding mesh size and is constructed, for example, as a screen fabric or non-woven fabric.

[0032] By constructing a first filter made of a metallic material, a stable and rigid structure is obtained, for example, capable of mechanical purification via brush strips or rubber lip strips. Especially when the first filter is constructed of nonwoven fabric, the filter can also be made of woven fabric, plastic fabric, or composite materials.

[0033] The first filter specifically includes a surface medium. This allows for purification in a simple manner.

[0034] More particularly advantageous is that the first filter is constructed such that it can mechanically purify. The first filter can easily remove dirt particles and, in particular, lint, to enable efficient cleaning operation of the cleaning machine.

[0035] In a structurally simple implementation, the first filter has a surface that is at least approximately square or rectangular in shape. This allows for a simple implementation of a cleaning machine with a filter unit, and the filter unit can be positioned on the cleaning machine in a space-saving manner.

[0036] Advantageously, the first filter has a maximum height of 5 cm. This allows it to be easily positioned on the housing and connected upstream of the second filter. More particularly advantageously, the filter can be removed from the housing, allowing the second filter to be effectively tapped or blown away, for example.

[0037] Furthermore, it is advantageous that at least one of the following exists:

[0038] -The second filter is constructed to be the main filter;

[0039] - The second filter is arranged inside the housing;

[0040] - The second filter is constructed as a planar pleated filter or a circular filter;

[0041] - The second filter includes surface filter media and / or depth filter media;

[0042] - The second filter is a suspended solids filter and / or a HEPA filter and / or a ULPA filter and / or a filter with dust class H or M according to DIN-EN60335-2-69, Annex AA and / or a filter with particulate class H13 according to at least EN1822-1.

[0043] - The second filter is fixed or detachably connected to the housing.

[0044] This enables the realization of an effective main filter. Because the first filter is capable of purification, it also allows for the possibility of other configurations for the main filter.

[0045] In a simple implementation, the first filter is constructed such that it forms the bottom of the housing. However, the bottom of the housing is permeable to the suction flow, allowing the suction flow to pass through the second filter.

[0046] In one advantageous embodiment, the housing has a receiving portion for a first filter, wherein the receiving portion is configured as a guide for the first filter, and the first filter is placed in the receiving portion in a drawer-like manner. Therefore, the first filter can be easily positioned on the housing for cleaning operations and can be removed from the housing so that, for example, the second filter itself can be cleaned.

[0047] Advantageously, the first filter is formed as a separate unit, which can be processed as a whole and can be separated from the housing. This provides easy access for the operator.

[0048] In one advantageous embodiment, the housing is constructed such that the second filter is arranged on the housing such that it can be tapped through the housing. The housing "taps" the object to separate dirt particles from the second filter and remove them from the filter unit.

[0049] In particular, at least one of the following is advantageous:

[0050] - The filter unit has a lower side that, when arranged on the cleaning machine, points towards the area of ​​dirt on the cleaning machine;

[0051] - The filter unit has an upper side that points towards the clean area of ​​the cleaning machine when it is arranged on the cleaning machine;

[0052] - The bottom and top sides of the filter unit are at least approximately parallel to each other.

[0053] This allows for simple positioning and removability of the filter unit.

[0054] Advantageously, the filter unit has a clean side and a dirty side, with a spacing direction between the clean side and the dirty side. An abutment device is arranged or formed on the housing, allowing the filter unit to be supported along the spacing direction for fixation to the cleaning machine and to be removed from the cleaning machine in the opposite direction. This provides simple positioning within the receiving section of the cleaning machine. The filter unit can be inserted into the receiving section from above and thus automatically and correctly positioned with respect to lateral movement. A fixed position can be easily achieved by clamping from above.

[0055] The object of the present invention is also to provide a floor cleaning machine of the aforementioned type, which can clean woven floors in an effective and simple manner.

[0056] This task is solved in the floor cleaning machine described at the beginning according to the invention by assigning at least one cleaning roller unit to at least one filter unit according to the invention.

[0057] Textile floors, such as carpeted floors, can be cleaned effectively by sweeping using a rotating cleaning roller unit.

[0058] The suction unit is specifically designed to prevent dirt particles already picked up by the cleaning roller unit from being loaded into the surrounding environment of the floor cleaner.

[0059] On surfaces made of textile materials, there is a problem that lint is also separated or carried away by at least one cleaning roller unit. This can easily cause filter clogging.

[0060] This situation can be prevented by using a filter unit according to the invention, which has a first filter as a pre-filter and a lint filter.

[0061] This also allows for the purification of the filter unit (without removing it from the floor cleaner), and especially for automatic purification. Purification is performed only on the first filter, so a filter such as a HEPA filter can also be used as a second filter that cannot be purified or can only be purified with great effort, or that must be removed from the floor cleaner for purification.

[0062] The aforementioned task is also solved according to the invention by means of the following: additionally or alternatively, a housing for at least one filter unit is arranged on a base, and a suction unit is at least partially arranged on a support, the support being movably positioned on the base, wherein the support has a first position or a first position region and a second position or a second position region, in the first position being effective for cleaning operation, and in the second position being positioned relative to the housing such that the filter unit can be removed from the housing in a direction away from the base.

[0063] The support bracket, which in particular keeps the blower of the suction unit movable, provides the corresponding space in a simple manner by transitioning from the first position or the first position area to the second position or the second position area. The operator can easily remove the filter unit from the housing or fix it to the housing through this space.

[0064] What can also be achieved in a simple way here is that the clean area provided by the floor cleaning machine offers access to the receiving area.

[0065] Therefore, the filter unit can be replaced in a simple way, or the machine itself can be cleaned from the outside.

[0066] Here, a first location area means providing multiple first locations, and a second location area means providing multiple second locations. In principle, it is possible to have only one or more first locations (i.e., a first location area). Similarly, it is possible to have only one or more second locations (second location areas).

[0067] A particularly advantageous feature is that, in the second position or area, the filter unit can be accessed from and removed from the clean area of ​​the floor cleaner, or inserted into the second receiving section from the clean area. This provides ease of operation for the operator, who does not need to enter the dirty area of ​​the floor cleaner to change the filter.

[0068] In a simple implementation, the support is arranged on the base in a manner that allows it to swing via a swing bearing. Therefore, it is easy to reach the first position or region from the second position or region, and conversely, it is easy to reach the second position or region from the first position or region.

[0069] At least one of the following is advantageous:

[0070] - The swing axis of the swing bearing is at least approximately parallel to the rotation axis of at least one cleaning roller unit;

[0071] - The oscillation axis of the oscillating bearing is at least approximately parallel to the wheel axis;

[0072] - The swing axis of the swing bearing is transverse to and, in particular, perpendicular to the longitudinal axis of the base.

[0073] A compact structure with a compact support arrangement is obtained by oscillating the axis of rotation relative to the axis of rotation of at least one cleaning roller unit, or in a parallel orientation relative to the wheel axis, or in an orientation perpendicular to the longitudinal axis of the base.

[0074] Advantageously, the base has a front end and a rear end, wherein the forward (traveling) direction of the floor cleaner is parallel to the longitudinal axis of the base, and wherein the longitudinal axis extends between the rear end and the front end, and the direction of movement when transitioning from a first position or first position area to a second position or second position area points towards the rear end. Therefore, the space behind the rear end of the base can be utilized to position the support unit, along with a portion thereof, in the second position or second position area. The support unit can, for example, be positioned between struts for guiding the floor cleaner by the operator. The floor cleaner can thus be constructed compactly and in a space-saving manner.

[0075] In one advantageous embodiment, at least one cleaning roller unit is arranged between the suction unit and the front end. This provides simple operability.

[0076] In one embodiment, in the first position or region, the bracket faces at least one side toward the battery housing and / or the support of the operation panel. This results in a compact structure.

[0077] A particularly advantageous feature is the inclusion of a purification device for the filter unit, and especially for the first filter, which is mounted on a base. This allows for the purification of the filter unit and the first filter therein without removing the filter unit from the floor cleaning machine. This results in efficient cleaning operation. In particular, the first filter can be automatically purified by the purification device.

[0078] In one embodiment, the purification device includes a drive motor positioned outside the projection area of ​​the first filter within the dirt area of ​​the floor cleaner. The projection area of ​​the first filter within the dirt area roughly corresponds to the area from which dirt particles can fall. By positioning the drive motor outside the projection area, the level of contamination directed towards the drive motor can be kept low.

[0079] In one embodiment, the purification device has at least one scraper, and particularly includes exactly one scraper for the filter unit. The scraper mechanically acts on the first filter and promotes purification. The scraper mechanically separates dirt particles (and especially lint) from the first filter.

[0080] In one embodiment, the first filter has at least an approximate rectangular or square shape, and at least one scraper is centrally supported about the first filter. Effective purification can then be facilitated by a single scraper.

[0081] A compact structure is achieved if at least one scraper has an effective area for purification, which corresponds at most to the middle width of the first filter. Here, the effective area of ​​the scraper is the length of the scraper that it can act on the first filter.

[0082] In a simple embodiment, at least one scraper is supported on a base in a manner that allows it to swing on a swing bearing. In particular, this allows for a vibratory swinging motion of the scraper, enabling the first filter to be cleaned in a wiper-like manner.

[0083] If the oscillating bearing is positioned outside the projection area of ​​the filter unit into the dirt area of ​​the floor cleaner, the dirt load on the oscillating bearing can be kept relatively small. This minimizes at least one direct dirt load on the oscillating bearing.

[0084] Advantageously, the swing axis of the swing bearing is oriented parallel to one side of the first filter, and especially the normal direction of the lower side. This allows for purification in a simple and effective manner, similar to a vibrating windshield wiper.

[0085] Advantageously, the oscillating bearing is centrally positioned about the outside of the filter unit. This results in a simple structural design. In particular, a simple scraper is sufficient for an effective purification process.

[0086] In one embodiment, a transmission device is provided that transmits the torque of the drive motor to at least one scraper. Specifically, an eccentric device is coupled to the drive motor of the purification device and to a rod, causing the rod to deflect. This allows torque to be transmitted to at least one scraper in an efficient manner. The eccentric device allows for a translational partial movement, enabling a vibrating pivoting rod spaced apart from the oscillating bearing of the scraper.

[0087] Advantageously, the rod is coupled to the push rod, and the push rod is coupled to at least one scraper. Torque can then be transmitted via the push rod to vibrate the scraper.

[0088] For this purpose, the push rod is hinged to the rod in a rotatable manner, and the wiper blade is hinged to the push rod in a rotatable manner. This allows for a simple driving motion of the wiper blade in the form of a windshield wiper.

[0089] Advantageously, the drive motor, acting on a rod via an eccentric device, is positioned outside the projection area of ​​the filter unit within the dirt area of ​​the floor cleaner. This keeps at least one direct load of dirt onto the rod relatively small.

[0090] More particularly advantageous is the provision of control and / or regulation devices that control the purification process, and especially control it so that purification is performed automatically after specific time intervals during cleaning operations. This results in simple operability.

[0091] It has proven advantageous that a specific time interval greater than 3 minutes, particularly greater than 4 minutes, and especially between 4 and 6 minutes. It has also proven advantageous that purification is performed if a filter cake, i.e., a combination of contaminant particles, has already formed on the first filter. If a longer time interval greater than 3 minutes exists for the cleaning operation, the filter cake is formed again. Due to the formation of the combination, contaminant particles can be separated from the first filter via, for example, a single scraper. To some extent, contaminant particles can also be pulled out from corner areas inaccessible to the scraper by the combination. This, in turn, allows for a compact structure.

[0092] Furthermore, it is advantageous to install control and / or regulation devices that shut off the suction unit in relation to the generation of the suction flow when the purification process is initiated. This results in effective purification.

[0093] Advantageously, a rechargeable battery pack is provided to power the electrical components of the floor cleaning machine. This results in simple operation; power cords and other such installations are unnecessary.

[0094] The floor cleaning machine according to the invention is particularly configured as a sweeper and as a sweeper for textile floors. The cleaning roller unit is thus configured as a sweeping roller. The bristles of at least one cleaning roller unit are embedded in the textile material of the corresponding floor and carry away dirt particles.

[0095] In addition, at least one of the following is advantageous:

[0096] -At least one cleaning roller unit is a main roller unit;

[0097] - At least one cleaning roller unit has a rotation axis that is oriented parallel to the mounting surface;

[0098] - At least one cleaning roller unit has a rotation axis that is oriented parallel to the wheel axis;

[0099] - At least one cleaning roller unit has a rotation axis that is transverse to and particularly perpendicular to the axis between the front and rear ends of the base;

[0100] - Place at least one side brush on the base;

[0101] - At least one side brush is driven in a rotatable manner;

[0102] - The rotation axis of at least one side brush is transverse to, and especially oriented at an acute angle (on the order of 75°) relative to the surface to be cleaned.

[0103] This results in an effective cleaning process.

[0104] Furthermore, the advantages are:

[0105] - A wheel assembly is installed on the base to enable the floor cleaning machine to move around;

[0106] - When the floor cleaning machine is running, it is supported on the floor to be cleaned by a wheel device;

[0107] - At least one cleaning roller unit is positioned on the base between the front end of the base and the rear wheel assembly;

[0108] - The floor cleaning machine is constructed as a push-type machine;

[0109] - A support for the operator is arranged on the base, with the support specifically designed for standing operators.

[0110] This results in simple operability. The operator can push the floor cleaning machine forward to clean a large area efficiently in a short time interval.

[0111] The present invention also relates to a method for operating a floor cleaning machine, and more particularly to a floor cleaning machine according to the present invention.

[0112] Here, the purification of the filter unit (located on the floor cleaner) and especially the first filter of the filter unit is performed automatically under time control, wherein the purification is performed after a specific time interval of the cleaning operation, and wherein the specific time interval is at least 3 minutes, especially at least 4 minutes and especially between 4 minutes and 6 minutes.

[0113] It has been shown that effective purification is achieved if a sufficiently long period of time is allowed to form a filter cake of contaminant particles on the first filter. Then, a composite formation emerges, which can be easily separated from the first filter.

[0114] In particular, it is not necessary for the scraper to move continuously through the first filter. To a certain extent, the corner area can also be ignored. Due to the formation of the filter cake, the dirt particles are thus "pulled out" from the corner by the combined formation.

[0115] Such a filter cake can be formed by waiting for a sufficiently long time and by pre-determining specific time intervals, thus enabling effective purification once again.

[0116] For purification purposes, the suction unit is shut off or turned off during the purification process to generate the suction flow. Attached Figure Description

[0137] One embodiment of the floor cleaning machine 10 according to the present invention includes a base 12. The base 12 forms the main body of the floor cleaning machine 10.

[0138] In one embodiment, the base 12 is configured as a chassis 14.

[0139] The base 12 has a front end 16 and a rear end 18. The base 12 is along axis 20 (…). Figure 5 It extends between the front-end 16 and the back-end 18.

[0140] When the floor cleaning machine 10 used for cleaning the floor 23 is operating normally, the axis 20 is parallel to the forward (traveling) direction 22 of the floor cleaning machine 10.

[0141] A wheel assembly 24 is arranged on the base 12. The wheel assembly 24 includes a rear wheel assembly 26 and a front wheel assembly 28. In one embodiment, the rear wheel assembly 26 (with respect to the forward (travel) direction 22) includes a left rear wheel 30a and a right rear wheel 30b.

[0142] The rear wheel assembly 26, which has a left rear wheel 30a and a right rear wheel 30b, is arranged in the area of ​​the rear end 18 of the base 12 (chassis 14).

[0143] The rear wheel assembly 26, which has a left rear wheel 30a and a right rear wheel 30b, has a common wheel axle 32.

[0144] In one embodiment, the front wheel assembly 28 consists of rollers 34 ( Figure 3 The roller 34 is arranged in the area of ​​the front end 16.

[0145] In one embodiment, roller 34 is configured as a steering roller.

[0146] A cleaning roller unit 36 ​​is arranged on the base 12. The cleaning roller unit 36 ​​is the main roller unit of the floor cleaning machine 10.

[0147] The cleaning roller unit 36 ​​is positioned on the base 12 between the front end 16 and the rear end 18. In one embodiment, with respect to axis 20, the cleaning roller unit 36 ​​is positioned between the front wheel assembly 28 and the rear wheel assembly 26.

[0148] The cleaning roller unit 36 ​​is arranged on the base 12 such that it extends beyond the lower side 38 of the base 12 at least during cleaning operation (see...). Figure 3 ), in which, during cleaning operation, the lower side 38 faces the ground to be cleaned.

[0149] Cleaning roller unit 36 ​​can rotate around axis 40 ( Figure 4 The rotation is supported. The axis of rotation 40 is parallel to the wheel axis 32.

[0150] Furthermore, the rotation axis 40 is oriented transversely to and here perpendicular to axis 20.

[0151] In addition, when the ground cleaning machine 10 is standing on the ground 23 as usual for cleaning operation, especially when the rotation axis 40 is oriented parallel to the ground 23 to be cleaned.

[0152] The floor cleaning machine 10 has a mounting surface 42 ( Figure 3 The mounting surface 42 is defined by the rear wheel assembly 26 and the front wheel assembly 28. If the floor cleaning machine 10 is conventionally placed on a flat surface 23 to be cleaned, then the mounting surface 42 coincides with the surface of the surface 23 to be cleaned.

[0153] The wheel axis 32 is parallel to the mounting plane 42.

[0154] The axis of rotation 40 is parallel to the placement plane 42 (and is spaced from the placement plane 42 in the height direction 44); see also Figure 4 The height direction 44 is perpendicular to the placement plane 42.

[0155] A motor device 46 is provided for rotating the cleaning roller unit 36 ​​to rotate around the rotation axis 40. Figure 5 Motor assembly 46 includes an electric motor. In one embodiment, motor assembly 46 includes a transmission mechanism for transmitting torque from the electric motor to the cleaning roller unit 36. In one embodiment, the transmission mechanism includes a speed reducer. The transmission mechanism may include a conveying device to transmit torque over a distance from the electric motor to the cleaning roller unit 36.

[0156] In one embodiment, the cleaning roller unit 36 ​​is supported on a rocker arm assembly 48. The rocker arm assembly 48 includes, for example, a first rocker arm 50 and a second rocker arm 52 spaced apart therefrom. Rotational bearings 54 are formed on the first rocker arm 50 and the second rocker arm 52, on which the cleaning roller unit 36 ​​is supported in a manner rotatable about a rotation axis 40.

[0157] The first rocker arm 50 and the second rocker arm 52 are connected by shaft 56 ( Figure 5 They are connected to each other.

[0158] The cleaning roller unit 36 ​​is supported at its ends on the first rocker arm 50 and the second rocker arm 52, respectively. The shaft 56 extends substantially along the length of the cleaning roller unit 36 ​​in a direction parallel to the axis of rotation 40.

[0159] In one embodiment, the motor assembly 46 is arranged on the rocker arm assembly 48 and positioned, for example, on the second rocker arm 52. The rocker arm assembly 48 is integrally supported on the base 12 in a swingable manner via a swing bearing 58. The shaft 56 forms the swing axis of the swing bearing 58.

[0160] When the motor assembly 46 is positioned on the rocker arm assembly 48, the motor assembly 46 (including any possible transmission mechanism in the inland area) can swing using the rocker arm assembly 48.

[0161] Oscillating bearing 56 (see Figure 5 The swing axis 60 is oriented parallel to the rotation axis 40 (and further parallel to the placement plane 42).

[0162] One or more side guards 62, which are associated with the cleaning roller unit 36, are mounted on the base 12 (see...). Figure 3 They laterally cover the cleaning roller unit 36.

[0163] In one embodiment, the floor cleaning machine 10 is configured as a sweeper. The cleaning roller unit 36 ​​is configured as a sweeping roller and particularly has a bristle liner.

[0164] In one embodiment, the floor cleaner 10 is configured as a sweeper for textile floors (and especially carpeted floors). The cleaning roller unit 36 ​​is thus correspondingly configured as a sweeping roller unit for textile floors and has a corresponding lining suitable for performing sweeping and cleaning functions on textile floors. The floor cleaner 10 also operates such that the cleaning roller unit 36 ​​has a corresponding rotational speed to achieve effective cleaning of textile floors.

[0165] The floor cleaning machine 10 includes a suction unit 64 ( Figure 5 ), which is arranged on the base 12.

[0166] Dirt particles picked up from the surface to be cleaned by the cleaning roller unit 36 ​​pass through channel 66 (see...) Figure 6 ) is transported to the waste collection container 67.

[0167] The waste collection container 67 is arranged on the base 12 in a detachable manner, so that the waste collection container can be emptied and cleaned.

[0168] When the floor cleaner 10 is running, the suction unit 64 generates a suction flow. This suction flow acts on the dirt particles within the channel 66 and, in particular, prevents the environment of the floor cleaner 10 from being "loaded" with dirt particles.

[0169] The suction unit 64 has at least one support function for conveying waste particles to the waste collection container 67.

[0170] The suction unit 64 has, at least in relation to some of its components, a blower 65a and a blower motor 65b arranged on the base 12, and is arranged particularly close to the rear end 18 compared to the front end 16 (see...). Figure 6 ).

[0171] In one embodiment, the suction unit 64 is positioned above the rear wheel assembly 26 about height 44.

[0172] Alternatively, the suction unit 64 can be positioned about axis 20 between the rear end 18 and the cleaning roller unit 36.

[0173] The motor unit 46 (and the suction unit 64 and the display unit 68) are powered via the battery unit 70 and, in particular, the rechargeable battery unit 70.

[0174] A first receiving portion 72 for a first battery 74 of a battery device 70 is arranged on the base 12. The first battery 74 is provided with a charging status display 76, which is located on the upper side of the first battery 74.

[0175] In one embodiment, the first receiving portion 72 is positioned about axis 20 between the motor assembly 46 and the suction unit assembly 64. In particular, it is positioned at least approximately centrally on the base 12 about axis 20.

[0176] In one embodiment, the first receiving portion 72 is effectively configured such that if the first battery 74 is positioned on the first receiving portion 72 (and the first battery is correspondingly charged), power can be supplied to the electrical appliances of the floor cleaning machine 10. In particular, the first receiving portion 72 is equipped with a corresponding power interface for this purpose.

[0177] A second receiving portion 78 is also arranged on the base 12 (see Figure 5The second battery is used for the battery device 70. The second receiving part 78 forms a storage position for another battery (i.e., the second battery of the battery device 70). This allows the replacement battery to be positioned on the floor cleaning machine 10.

[0178] In one embodiment, the second receiving portion 78 is configured such that the second battery positioned thereon is ineffective for supplying power to the electrical appliances of the floor cleaning machine 10. Specifically, no electrical interface is provided to the second receiving portion 78.

[0179] In one embodiment, the second receiving portion 78 is arranged next to the first receiving portion 72 about axis 20.

[0180] The second receiving portion 78 is positioned between the front end 16 and the rear end 18 of the base 12.

[0181] Alternatively or additionally, the second receiving portion 78 is positioned between the front end 16 of the base 12 and the first receiving portion 72.

[0182] Adjacent to the first receiving part 72, an operation panel 84 is arranged on the base 12. A display device 68 is positioned on the operation panel 84.

[0183] In addition, a switch 86 is arranged on the operation panel 84 (see Figure 2 Additionally, an operating element 88 is arranged on the operation panel 84 for adjusting the height or clamping force of the cleaning roller unit 36.

[0184] In one implementation method ( Figure 5 In this configuration, the control panel is arranged between the first receiving portion 72 and the second receiving portion 78.

[0185] The first receiving part 72, the operation panel 84, and the second receiving part 78 are flush with each other on a line perpendicular to the axis 20 and, in particular, parallel to the wheel axis 32.

[0186] A removable housing device 90 is arranged on the base 12. Figures 1 to 4 The housing assembly 90 is shown in the figure. Figure 5 In the middle, the housing device 90 has been removed.

[0187] Here, the removability of the housing device 90 from the base 12 means that the housing device 90 can be completely removed or arranged on the housing device 90, for example, in a swingable or movable manner.

[0188] The housing assembly 90 covers the components of the floor cleaner 10 arranged on the base 12. It covers the rocker arm assembly 48 and the suction unit assembly 64, especially on the upper side of the floor cleaner 10.

[0189] The housing assembly is formed by a housing cover 90, wherein the base 12 is a housing base for the housing cover.

[0190] When the housing device 90 is arranged on the base 12, the second receiving part 78 (which may have a second battery held thereon) is covered by the housing device 90.

[0191] The housing assembly 90 has a window 92 ( Figures 1 to 3 ). Window 92 is arranged within the area of ​​the first receiving portion 72 and positioned such that the charging status display 76 of the first battery housed within the first receiving portion 72 is located at window 92 (when the housing 90 is positioned on the base 12). Thus, the operator of the floor cleaning machine 10 can directly read the charging status of the first battery via the charging status display 76.

[0192] Here, window 92 has window 94, which has a normal direction 96 (see...). Figure 3 In one embodiment, the normal direction 96 is oriented perpendicular to the mounting plane 42. If the floor cleaning machine 10 is conventionally positioned on the surface 23 to be cleaned with its lower side 38 facing the surface 23 to be cleaned, then the mounting plane 42 points to the upper side 98 of the floor cleaning machine 10.

[0193] The operator can thus identify the charging status display 76 from above through window 92.

[0194] In principle, it is feasible to close the window 92 with window glass. In a simplified manufacturing embodiment, the window 92 is formed as a through recess within the housing assembly 90.

[0195] In an advantageous embodiment, the window 92 is configured such that when the housing device 90 is positioned on the base 12, the operation panel 84 is also located at the window 92.

[0196] For window 92, another window can be set as an alternative.

[0197] Window 92 or another window is formed as a through recess in the area of ​​the operation panel 84, so that the operator can reach the operating element 88 through window 92 or another window. Alternatively, the operating element 88 extends beyond window 92 or another window to facilitate operation by the operator.

[0198] A support 100 for the operator, especially a standing operator, is arranged on the base 12. The support 100 is located in the area of ​​the rear end 18. The floor cleaning machine 10 is thus configured as a push-type machine, wherein the operator standing behind the floor cleaning machine 10 pushes the floor cleaning machine on the surface 23 to be cleaned via the support 100.

[0199] In one embodiment, the bracket 100 includes a retaining rod 102 that is spaced apart from the base 12.

[0200] The retaining rod 102 is connected to the base 12 via a first support rod 104a and a second support rod 104b spaced apart from the first support rod.

[0201] In one embodiment, the support 100 is arranged on the base 12 in a swingable manner. This allows for matching the height of the operator (standing operator) if necessary. Furthermore, the support 100 can be flipped over the housing 90 during the storage and positioning of the floor cleaner 10, thereby reducing the size of the floor cleaner 10 in the height direction 44 and its length along the axis 20.

[0202] The floor cleaning machine 10 includes a height adjustment device, via which the height positioning of the cleaning roller unit 36 ​​(in the height direction 44) can be adjusted and fixed. In particular, if cleaning operation is not performed, the cleaning roller unit 36 ​​can be positioned spaced apart from the mounting surface 42 by means of the height adjustment device 106.

[0203] Alternatively or additionally, the clamping force applied by the cleaning roller unit 36 ​​to the surface 23 to be cleaned can be adjusted by the height adjustment device 106.

[0204] Excessive pressure or clamping force may damage the surface covering of the floor 23 to be cleaned and / or damage the motor assembly 46. Such damage can be avoided (when properly adjusted) by the height adjustment device 106.

[0205] The height adjustment or clamping force adjustment of the cleaning roller unit 36 ​​with respect to the base 12 is achieved by adjusting (and fixing) the swing arm device 48 on the swing bearing 58.

[0206] The control panel 84 includes a bracket 108. A rotary handle 109, serving as an operating element 88, is rotatably supported on the bracket 108.

[0207] The floor cleaner 10 and, particularly, the base 12, are provided with a housing 110 for the filter unit 112 (see, for example, see...). Figure 6 In one embodiment, the receiving portion 110 is arranged on the wheel assembly 24 about the height direction 44.

[0208] If the filter unit 112 is located within the housing 110, then the filter unit is positioned with respect to the suction flow between the channel 66 and the suction unit 64 (and particularly within the blower 65a). The filter unit 112 is used to filter out dust particles.

[0209] Regarding the filter unit 112 located within the housing 110, the floor cleaner has a soiled area 114 and a clean area 116. The soiled area 114 and the clean area 116 are separated by the filter unit 112. Effective fluid connection between the soiled area 114 and the clean area 116 is achieved only through the filter unit 112. Outside the filter unit 112, the soiled area 114 and the clean area 116 are fluid-tightly separated from each other.

[0210] The filter unit 112 has a dirt side 118 pointing to the dirt area 114 and a clean side 120 pointing to the clean area 116.

[0211] On the contaminated side 118, the filter unit 112 is loaded with a suction flow carrying contaminated material. On the clean side 120, the suction flow is clean.

[0212] The floor cleaning machine 10 has a bracket 122 for the suction unit 64, and particularly for the blower 65a and blower motor 65b. The bracket 122 ( Figures 6 to 8 , Figure 13 The suction unit 64, together with the portion of the unit located on the support 122 (especially within the blower 65a and blower motor 65b), is movable relative to the base 12.

[0213] In one embodiment, the bracket 122 is positioned via a swing bearing 124 in a manner that allows it to swing about a swing axis 126. Here, the swing axis 126 ( Figure 5 Parallel to the axis of rotation 40 or parallel to the wheel axis 32.

[0214] The swing axis 126 is located in the area of ​​the rear end 18 of the base 12.

[0215] The bracket 122 has a first (swinging) position 128. Figure 8 (or the corresponding first swing position area), wherein the bracket 122 is positioned about the receiving portion 110 with the filter unit 112 as follows, that is, effective cleaning operation can be achieved.

[0216] If the filter unit 112 is placed inside the housing 110 ( Figure 7 If the bracket 122 is positioned such that it is in contact with the clean side 120 of the filter unit 112, a fluid seal is achieved via the bracket 122.

[0217] In the first position 128 of the bracket 122, the suction unit 64 generates a suction flow that flows through the filter unit 112 in a direction from the dirty side 118 to the clean side 120.

[0218] The support 122 has a second (swinging) position (or a corresponding second position region), wherein the support 122 pivots away from the receiving portion 110. Figure 8 ).

[0219] In this second position 130, the receiving portion 110 with the filter unit 112 is accessible to the operator from the clean area 116. The operator can remove the filter unit 112 as a whole from the clean area 116. The corresponding removal direction is... Figure 8 The arrow with reference numeral 132 is used to indicate this.

[0220] The operator can remove the filter unit 112 upwards in the height direction 44.

[0221] In one embodiment, the support 122 is arranged on the base 12 such that it can swing in the direction 134 ( Figure 7 The pivot is made so as to move from the first position 128 to the second position 130. Here, the swing direction 134 is toward the rear end 18.

[0222] The support 122 can then pivot rearward on the base 12 and swing through, in particular, between the struts 104a and 104b of the (operator) support 100, so as to enable free access to the receiving part 110.

[0223] Accordingly, the support 122 is configured to match the suction unit 64, that is, to enable pivoting within the free area between the support rods 104a and 104b.

[0224] In particular, it can be configured that if housing assembly 90 has been removed (see...) Figure 5 If this is done, the operator can perform a pivoting motion on the support 122 of the suction unit 64.

[0225] The bracket 122 is arranged adjacent to the first receiving portion 72 for the battery device or the bracket 108 for the operation panel 84. Specifically, the bracket 122 is positioned between the bracket 108 of the first receiving portion 72 or the operation panel 84 and the rear end 18. The bracket 122 for the suction unit 64 has a region 135 ( Figure 7 , Figure 8 The area is located in the first position 128 facing the first receiving part 72 or the support 108.

[0226] In one embodiment, the bracket 122 for the suction unit 64 can be accessed via the rubber belt 123 in the first position 128. Figure 5 ) Fixing. In particular, in the first position 128 of the bracket 122, the bracket rests against the facility 125. This prevents downward pivoting and thus just defines the first position 128.

[0227] The rubber band 123 is on the base 12 and hooked by a corresponding hook 127; the rubber band is constructed as a closed loop. This prevents the support 122 from swinging upward away or at least makes it difficult to swing away.

[0228] Filter unit 112 ( Figures 9 to 12 It is a unit that can be processed as a whole, and it can be positioned as a whole in the receiving part 112 and removed as a whole from the receiving part 112.

[0229] The filter unit 112 includes a housing 136 having an internal space 138.

[0230] The filter unit 112 is configured as a filter box. In one embodiment, the housing 136 has at least an approximately rectangular shape. Accordingly, the internal space 138 of the housing has a hollow cuboid shape.

[0231] The filter unit 112 has a lower side 140 and an upper side 142. The lower side 140 faces the soiled area 114 when positioned on the floor cleaner 10. The upper side 142 faces the clean area 116.

[0232] An abutment device 144 is disposed on the housing. The abutment device is specifically positioned in the upper region 142.

[0233] If the filter unit 112 is placed on the receiving portion 110, the abutment device 144 is supported on the corresponding opposite surface of the receiving portion 110. The movement of the filter unit 112 on the receiving portion 110 is blocked in the opposite direction of the height direction 44.

[0234] If the bracket 122 is in the first position 128, it presses the filter unit 112 from above, thereby fixing the filter unit 112 in the corresponding position within the receiving portion 110.

[0235] If the bracket 122 is in the second position 130, the filter unit 112 can be removed from the receiving portion 110 upwards (in the direction from the lower side 140 to the upper side 142).

[0236] By locking the bracket 122 about the base 12 (by the rubber band 123) in the first position 128, the positioning of the filter unit 112 in the receiving part 110 is also locked.

[0237] The receiving portion 110 is configured as a receiving box whose dimensions match those of the filter unit 112. In particular, the matching is such that if the filter unit 112 is placed inside the receiving portion 110 and the support 122 is in the first position 128, the suction flow can only pass through the filter unit 112 (and in particular without passing by) from the dirty area 114 into the clean area 116.

[0238] In one embodiment, a seal is arranged or constructed on the lower side 140 of the filter unit 112, which cooperates with the corresponding opposite side of the receiving portion 110 for the corresponding fluid seal to prevent erroneous airflow from the suction flow.

[0239] Filter unit 112 includes a first filter 146 and a second filter 148. The first filter 146 is located upstream of the second filter 148 with respect to the suction flow (in the direction of the suction flow from the dirty area 114 into the clean area 116).

[0240] The first filter 146 is configured as a lint filter. The second filter 148 is the main filter of the filter unit 112.

[0241] The second filter 148 is arranged within the internal space 138 of the housing. In principle, it can be arranged in a manner that allows it to be separated from the housing 136, or it can be fixedly arranged within the housing.

[0242] In one embodiment, the housing 136 is configured such that the second filter 148 is arranged on the housing 136 such that the second filter 148 can be tapped through the housing 136. The operator holds the housing 136 and "taps" the object to dislodge dirt particles from the second filter 148.

[0243] The second filter includes surface filter media and / or depth filter media as filter materials. It is constructed, for example, as a suspended solids filter and / or a HEPA filter and / or a ULPA filter and / or a filter with dust class H or M according to DIN-EN60335-2-69, Annex AA and / or at least a filter with particulate class H13 according to EN1822-1.

[0244] In one embodiment, the second filter 148 is configured as a planar pleated filter.

[0245] The clean side 120 is located specifically on the second filter 148.

[0246] The first filter 146 is configured to filter out lint. The first filter 146 is particularly configured to retain particles with a size of at least 100 μm, particularly at least 150 μm and particularly typically at least 200 μm.

[0247] In particular, the first filter 146 is configured as a surface filter.

[0248] In one embodiment, the first filter 146 forms the bottom 150 of the housing of the filter unit 112.

[0249] A receiving portion 152 is arranged on the housing 136 in the region of the lower side 140. The first filter 146 is a unit that can be processed as a whole. The first filter 146 can be pushed into the receiving portion 152 on the housing 136 in a drawer-like manner and then removed accordingly. The first filter 146 forms a separable housing bottom 150 of a filter unit 112 (see...). Figure 11 and Figure 12 ).

[0250] The first filter 156 includes a coil structure 154 as the filter material. The coil structure 154 is placed on a frame 156. The frame 156 is, for example, a plastic frame that is injection molded onto the coil structure 154, or the coil structure 154 is held in corresponding tracks on the frame 156. The coil structure 154 is, for example, a mesh fabric or non-woven fabric. The coil structure 154 is particularly made of a metallic material.

[0251] In one embodiment, the first filter 146, together with its frame 156, has a square or rectangular shape that matches the shape of the housing 136.

[0252] The coil structure 154 is constructed, and in particular, rigidly constructed, such that the first filter 146 can mechanically clean. (The second filter 148 may be constructed such that it cannot mechanically clean; in one embodiment of the floor cleaner 10, no mechanical cleaning of the second filter 148 is provided.)

[0253] In one embodiment, the first filter 146 is configured in a planar manner. For example, the height H of the first filter 146 (in the direction between the dirty side 118 and the clean side 120) is 5 cm or less (see [reference]). Figure 11 ).

[0254] The mesh of the coil structure 154 is constructed such that particles of at least 100 μm size, and especially the fibers of textile materials, are trapped.

[0255] The floor cleaning machine 10 includes a filtration unit 112 and a purification device 158, which is here for a first filter 146.

[0256] The purification device 158 includes a drive motor 160, which is in particular an electric motor.

[0257] In one embodiment, if the filter unit 112 is positioned on the receiving portion 110, the drive motor 160 is arranged outside the projection area 162 of the filter unit.

[0258] The projection area 162 is a virtual extension of the filter unit 112 within the contaminated area 114 along direction 164, which is the normal direction relative to the contaminated side 118 of the filter unit 112. Direction 164 is also the direction from the clean side 120 to the contaminated side 118.

[0259] The drive motor 160 is thus positioned outside the area of ​​the floor cleaner 10 where dirt cleaned from the filter unit 112 falls.

[0260] The drive motor 160 is driven, in particular, by the battery device 70.

[0261] In one embodiment, the drive motor 160 is arranged next to the housing 110 of the filter unit 112 and, for example, about axis 20, such that the housing 110 is positioned between the drive motor 160 and the rear end 18.

[0262] The purification device 158 also includes at least one scraper 166, and specifically exactly one scraper 166. This scraper is arranged in a swinging manner on a swing bearing 168 (see, for example, see...). Figure 14 On the ), the swing axis 170 of the swing bearing 168 is oriented parallel to the distance between the dirt side 118 and the clean side 120 of the filter unit 112.

[0263] Regarding the sides 172a and 172b of the filter unit 112, the swing bearing 170 is particularly centrally arranged on the first filter 146.

[0264] The oscillating bearing 170 is located outside the projection area 162.

[0265] The scraper is configured, for example, as a brush or a rubber lip strip, which acts mechanically on the first filter 146.

[0266] The scraper 176 can be driven by the drive motor 160 to move on the first filter 146 in a wiper-like manner in order to perform purification.

[0267] A transmission device 174 is provided to transmit torque from the drive motor 160 to the oscillating bearing 170 and then to the scraper 166.

[0268] In one embodiment, the conveying device 174 includes a rod 176 (see...). Figure 14 and Figure 17 The rod 176 is supported on the base 12 near the receiving portion 110 in a swingable manner via a swing bearing 178. Here, the swing axis is parallel to the swing axis 170.

[0269] Member 176 includes an elongated hole 180.

[0270] An eccentric device 182 is effectively coupled to the torque of the drive motor. The eccentric device is inserted into the elongated hole 180 via a pin 184.

[0271] When the motor shaft of the drive motor 160 rotates accordingly, the pin 184 also performs a translational movement.

[0272] This translational motion causes the rod 176 to pivot on the oscillating bearing 178.

[0273] A push rod 186 is coupled to the rod 176 in a swinging manner via a corresponding swing bearing 188. The swing axis of the swing bearing 188 is parallel to the swing axis of the swing bearing 178.

[0274] The push rod 186 is coupled to the rod 176 in a swinging manner via a swing bearing 190, wherein the swing bearing 190 is spaced apart from the swing bearing 186. The swing axis of the swing bearing 190 is parallel to the swing axis of the swing bearing 188.

[0275] The reciprocating motion of lever 176 is actuated by drive motor 160 through coupling with lever 176. This reciprocating motion is transmitted to scraper 166, which then performs its own reciprocating motion. Figure 14 The image is indicated by a double arrow with reference numeral 192. The wiper 166 is thus driven by the drive motor 160 to move on the first filter 146 in the form of a wiper and perform the purification function.

[0276] It can be configured that the transmission device 174 includes a worm gear drive mechanism to facilitate speed reduction. This allows for relatively low noise generation.

[0277] In addition, this can also achieve torque deflection.

[0278] By arranging the oscillating bearing 168 in the center, the reciprocating motion 192 of the scraper 166 can be started from the middle position.

[0279] exist Figure 14 The maximum deflection to one side is shown in the figure, while... Figure 15 The maximum deflection toward the other side is shown in the figure.

[0280] The length 194 of the scraper 166 is particularly smaller than the corresponding diagonal of the first filter originating from the oscillating bearing 168. The length 194 of the scraper 166, for example, corresponds to the width of the first filter 146 or is slightly parallel to sides 172a or 172b with respect to the effective area of ​​the scraper used for purification.

[0281] Effective purification can be achieved through the appropriate length of the scraper 166, as further explained below. This allows for a compact and space-saving structure.

[0282] Figure 16 It shows not only the maximum deflection to one side but also the maximum deflection to the other side.

[0283] The floor cleaning machine 10 includes a control and / or adjustment device 196. Figure 19 ), and their corresponding protected areas are arranged.

[0284] The control and / or regulation device automatically controls the purification process, and in particular initiates the purification process and controls the duration of the purification process.

[0285] This is the drive motor 160 of the purification device 158.

[0286] Furthermore, it is preferred that the control and / or regulating device 196 also drives the blower motor 65b, more specifically, it is preferred that the blower motor 65b is not activated during the purification process, i.e., the blower motor 65b is not activated.

[0287] Advantageously, the control and / or regulation device 196 that automatically initiates the purification process automatically drives the purification process after a specific time interval during the cleaning operation, wherein the specific time interval is advantageously at least 3 minutes and especially at least 4 minutes, particularly in the range of 4 minutes and 6 minutes, and preferably 5 minutes. This achieves effective removal of the filter cake from the first filter, as will be further explained below.

[0288] The functions of the floor cleaning machine 10 are as follows:

[0289] The floor cleaning machine 10 is configured as a push-type machine. The operator stands behind the machine (behind the rear end 18) and moves the floor cleaning machine across the surface to be cleaned. Here, the operator specifically holds the retaining lever 102. The operator pushes the floor cleaning machine 10 back and forth.

[0290] In particular, the ground cleaning machine 10 does not have a driving mechanism.

[0291] In one alternative implementation, there is a travel drive.

[0292] In one embodiment, if the rotation direction of the cleaning roller unit is corresponding, the rotation of the cleaning roller unit 36 ​​causes the floor cleaning machine 10 to move forward when acting on the surface 23 to be cleaned.

[0293] The floor cleaning machine 10 is used to clean textile floors, such as carpeted floors. The cleaning roller unit 36 ​​forms a sweeping roller unit with corresponding bristles for "sweeping" carpeted floors.

[0294] The corresponding floor cleaning machine 10 has an effective cleaning effect. It can be used to clean large areas of woven floors in a simple way. Compared with a pure vacuum cleaner, it generates relatively less noise.

[0295] Dirt particles from the surface 23 to be cleaned are carried by the cleaning roller unit 36 ​​and fed into the channel 66. From there, they enter the dirt collection container 67.

[0296] The suction unit 64 prevents dirt particles from being distributed into the environment of the floor cleaner 10.

[0297] The filter unit 112 is configured as a filter cartridge and includes a first filter 146 as a pre-filter and a lint filter and a second filter 148 as a main filter.

[0298] Lint is generated during the cleaning of the textile floor and is carried by the cleaning roller unit 36. This lint is relatively large and can quickly clog the second filter 148. To avoid this, a first filter 146 with a coil structure 154 is provided. The coil structure 154 is configured to capture, for example, particles (corresponding to lint) with a size of 200 μm or larger.

[0299] The filter unit 112 is configured such that the first filter 146 can be purified by the purification device 150 of the floor cleaner 10.

[0300] The filter unit 112 is positioned on the housing 110 of the floor cleaner. The suction unit 64 can be positioned in the first position 128 via the bracket 122. Figure 7 ).

[0301] In order to remove the filter unit 112, the support 122 is guided from the first position 128 to the second position 130, particularly by a swinging motion along the swing direction 132. The filter unit 112 can thus be lifted off the receiving portion 110 as a whole. Here, the operator can access the filter unit 112 via the edge region 116 to lift it off.

[0302] The first filter 146 can be removed from the filter unit 112, which is isolated from the floor cleaner 10, and especially removed from the housing 136 of the filter unit 112 in a drawer-like manner (similar to...). Figure 11 ).

[0303] The filter unit 112 can be tapped via the housing 136 to shake dust particles off the second filter 148. Alternatively, the filter unit 112 can be blown out. In particular, the first filter 146 and the second filter 148 can be blown out separately.

[0304] When the floor cleaning machine is running, the purification process via the purification device 158 is automatically executed by the control and / or regulation device 196 after a specific time interval of cleaning operation.

[0305] In this setting, the blower motor 65b is shut off for the purification mode, meaning the suction unit 64 is inactive. The control and / or regulating device 196 accordingly drives the blower motor 65b.

[0306] During the purification process, the drive motor 160 drives the scraper 166 to move in a vibratory manner via the transmission device 174. The scraper 166 acts as a windshield wiper, moving past the dirt side 118 of the first filter 146, where it removes dirt from the upper surface of the first filter 146.

[0307] This is Figure 13 The diagram is shown schematically.

[0308] It has been shown that deposits and, in particular, lint are formed on the first filter 146, resulting in deposit 198. Figure 13 ; Figure 18 In particular, filter cake 200 is formed on the first filter 146.

[0309] According to the invention, the specific time interval for the cleaning operation after purification is selected to be such a long that a filter cake 200 can be formed. Specifically, the time interval for the cleaning operation after purification is at least 3 minutes, and more particularly at least 4 minutes. For example, this time interval is in the range of 4 minutes to 6 minutes. In one specific embodiment, the time interval is approximately 5 minutes.

[0310] A composite formation 198 is formed by forming a filter cake 200 on the first filter 146. If the scraper 166 acts on the filter cake 200 or the composite formation 198, it carries away most of, and especially in the corner regions 202, the contaminant particles. By forming the composite formation 198 on the first filter 146, the scraper 166 can remove contaminant particles from the first filter 146 in addition to its direct area of ​​influence.

[0311] It is unnecessary for the scraper 166 to extend into the corresponding corner area 202.

[0312] For example, it would be sufficient if the effective length 194 of the scraper 166 is less than the corresponding diagonal and, for example, equal to or less than the corresponding width of the first filter 146 parallel to the sides 172a, 172b.

[0313] This results in a compact structure.

[0314] The control and / or regulating device 196 automatically executes the purification process under time control. After a specific time interval, the blower motor 65b is turned off, and the drive motor 160 of the purification device 158 is correspondingly controlled. The scraper 166 performs its vibratory oscillating motion. This vibratory oscillating motion is performed within a specific time range.

[0315] Then the control and / or regulating device 196 shuts off the drive motor 160 again and turns on the blower motor 65b for another cleaning operation, provided that the floor cleaner is not turned off by the main switch during this period.

[0316] The floor cleaning machine according to the present invention can effectively clean textile floors. It can perform automatic purification.

[0317] The floor cleaning machine demonstrates effective cleaning results, and its compact design allows for easy operation by the user.

[0318] In particular, the battery operation of the floor cleaning machine 10 can be achieved in a simple way.

[0319] To support the cleaning process, and especially for cleaning along baseboards or walls, in one embodiment, at least one side brush 204 is arranged on the floor cleaning machine 10. Here, in one embodiment, the side brush 204 extends beyond the front end 16 of the base 12. Furthermore, it extends laterally beyond the base 12 so as to enable even edge cleaning.

[0320] Specifically, the side brush 204 is driven to rotate, wherein the corresponding axis of rotation is oriented laterally and, for example, perpendicularly to the placement plane 42.
