Description

Floor brush assemblies and cleaning equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on July 21, 2023, with application number "202321935744.3" and application name "Floor brush assembly and cleaning equipment", all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of cleaning equipment, and in particular to a floor brush assembly and a cleaning equipment. Background Art

[0003] At present, cleaning equipment such as floor scrubbers are emerging popular household cleaning appliances that integrate sweeping, mopping and washing. However, there is a common problem of a large amount of residual water stains on the ground after using floor scrubbers for cleaning.

[0004] In the related art, a water squeezing roller is usually arranged on one side of the roller brush, and a bearing is arranged on the side of the water squeezing roller away from the roller brush. The circumferential sides of the bearing and the water squeezing roller abut against each other, so that when the roller brush rotates, the water squeezing roller is supported by the bearing and abuts against the roller brush, thereby squeezing out the accumulated water on the roller brush.

[0005] However, under this solution, the sliding friction between the squeeze roller and the bearing bushing causes the squeeze roller to have a large resistance, which affects the rotation of the roller brush and the cleaning effect of the floor scrubber.

[0006] Summary of the Invention

[0007] The present application aims to at least solve or improve the technical problem in the prior art that the upper water squeezing roller of the cleaning equipment is supported by a bearing, resulting in a large rotational resistance of the water squeezing roller, thereby affecting the cleaning effect of the floor scrubber.

[0008] To this end, the first aspect of the present application proposes a floor brush assembly.

[0009] A second aspect of the present application provides a cleaning device.

[0010] In view of this, according to the first aspect of the present application, the present application proposes a floor brush assembly, comprising: a shell; a roller brush, rotatably arranged on the shell; a squeezing roller, arranged on the shell through a bearing, the circumferential side of the squeezing roller and the circumferential side of the roller brush are in contact with each other, and the squeezing roller squeezes the roller brush; wherein, when the roller brush rotates, the squeezing roller rotates with the roller brush.

[0011] The floor brush assembly proposed in the present application includes a shell, a roller brush and a squeezing roller. The roller brush and the squeezing roller are rotatably arranged on the shell, and the circumferential side of the squeezing roller is in contact with the circumferential side of the roller brush. In addition, the squeezing roller applies a pre-tightening force to the roller brush so that the squeezing roller squeezes the roller brush. When the roller brush rotates, the roller brush can drive the squeezing roller to rotate through friction, and the squeezing roller can discharge the liquid adsorbed by the fluff on the surface of the roller brush, so that the surface of the roller brush is drier and water collection on the cleaning surface is reduced.

[0012] In addition, the squeezing roller is arranged on the shell through a bearing, which reduces the setting of the bearing shell, so that the squeezing roller is only subjected to rolling friction, making the rotation of the squeezing roller smoother, reducing the resistance of the squeezing roller, making the roller brush rotate more smoothly, improving the working stability of the squeezing roller, and improving the cleaning effect of the cleaning equipment.

[0013] In addition, the squeezing roller and the roller brush are both rotating, so there is rolling friction between the squeezing roller and the roller brush. The rolling friction is low, which can reduce the damage to the fluff on the surface of the roller brush, improve the cleaning effect, and increase the service life of the roller brush.

[0014] In addition, the floor brush assembly according to the above embodiment provided by this application may also have the following additional technical features:

[0015] In some embodiments, optionally, the shell includes: a shell body; a bracket, which is arranged on the shell body, and the squeezing roller is rotatably arranged on the bracket.

[0016] In this embodiment, the housing includes a housing body and a bracket. The bracket is arranged on the housing body, and the squeezing roller is rotatably arranged on the bracket, thereby facilitating the installation of the squeezing roller and the housing and reducing the difficulty of installation.

[0017] In some embodiments, optionally, the shell further includes: an elastic member, one end of which is connected to the shell body, and the other end of which is connected to the bracket, and the elastic member enables the squeezing roller to squeeze the roller brush.

[0018] In this embodiment, the shell also includes an elastic member arranged between the shell body and the bracket, one end of the elastic member is connected to the shell body, and the other end of the elastic member is connected to the bracket, and the elastic member is in a pre-tightened state, thereby supporting the bracket, so that the bracket brings the squeezing roller to squeeze the roller brush. That is, through the setting of the elastic member, the squeezing effect of the squeezing roller on the roller brush can be ensured, so that the liquid on the roller brush can be discharged more thoroughly.

[0019] In some embodiments, optionally, the shell further includes: comb teeth, which are arranged on the bracket and located on one side of the squeezing roller, with the comb teeth facing the roller brush.

[0020] In this embodiment, the shell also includes comb teeth, which are arranged on the bracket and facing the roller brush, and the comb teeth are arranged on one side of the extrusion roller. When the roller brush rotates, the comb teeth can scrape off debris on the roller brush, reducing the difficulty of cleaning the roller brush.

[0021] In some embodiments, the comb teeth are optionally located below the squeezing roller.

[0022] In this embodiment, when the roller brush rotates, it usually rotates from outside to inside, that is, the rotation direction of the position where the roller brush and the squeezing roller are in contact is upward. Therefore, the comb teeth are arranged below the squeezing roller so that when the roller brush rotates, it can pass through the comb teeth first and then through the squeezing roller. That is, before the squeezing roller squeezes the roller brush, the debris on the roller brush is scraped off first, making it easier for the comb teeth to scrape off the debris, reducing the difficulty of cleaning the roller brush, and reducing the possibility of debris being entangled on the squeezing roller, thereby improving the stability of the squeezing roller.

[0023] In some embodiments, optionally, the bracket includes a liquid outlet, and a port at one end of the liquid outlet faces the roller brush.

[0024] In this embodiment, the bracket is provided with a liquid outlet, and a port at one end of the liquid outlet faces the roller brush, so that liquid can be sprayed toward the roller brush through the liquid outlet to facilitate the roller brush to clean the surface to be cleaned.

[0025] In some embodiments, the bracket is optionally embedded in the housing body.

[0026] In this embodiment, the bracket is embedded in the shell body, thereby improving the stability of the bracket, better supporting the squeezing roller, and reducing the possibility of the squeezing roller tilting or separating from the roller brush.

[0027] In some embodiments, optionally, the housing includes: a cantilever beam, and the roller brush is arranged on the cantilever beam.

[0028] In this embodiment, the housing includes a cantilever beam, and the roller brush is arranged on the cantilever beam, so that the roller brush can be conveniently used to clean corners.

[0029] In some embodiments, optionally, it further includes: the roller brush and the squeezing roller are both cylindrical structures, the roller brush and the squeezing roller extend in the same direction, and the circumference of the roller brush and the circumference of the squeezing roller fit together.

[0030] In this embodiment, the roller brush and the squeezing roller are both cylindrical structures, and the axis of the roller brush and the axis of the squeezing roller are arranged roughly parallel, so that the circumferential side of the squeezing roller can better fit the circumferential side of the roller brush, thereby improving the liquid drainage effect of the roller brush.

[0031] In some embodiments, optionally, there are multiple squeezing rollers, and along the axial direction of the roller brush, the multiple squeezing rollers squeeze different positions of the roller brush.

[0032] In this embodiment, there are multiple squeezing rollers, and along the axial direction of the roller brush, the multiple squeezing rollers squeeze different positions of the roller brush, thereby reducing the length of the squeezing roller, reducing the possibility of deformation of the squeezing roller, and improving the squeezing effect of the squeezing roller on the roller brush, thereby improving the squeezing effect of the squeezing roller on the roller brush without setting a bearing.

[0033] In some embodiments, optionally, there are multiple bearings, and the multiple bearings are respectively arranged at both ends of the squeezing roller, and the squeezing roller is connected to the housing through the bearings.

[0034] In this embodiment, the floor brush assembly includes multiple bearings, and the squeezing roller is mounted on the housing via the bearings, thereby reducing the resistance of the squeezing roller and the friction on the bristles of the roller brush. Specifically, when there are multiple squeezing rollers, at least one bearing is provided at each end of each squeezing roller, thereby improving the squeezing effect of the squeezing roller on the roller brush.

[0035] According to a second aspect of the present application, the present application proposes a cleaning device, comprising: a floor brush assembly as proposed in any one of the above embodiments.

[0036] The cleaning device proposed in this application includes the floor brush assembly proposed in any of the above embodiments, and therefore has all the beneficial effects of the floor brush assembly proposed in any of the above embodiments, which will not be stated one by one here.

DETAILED DESCRIPTION

[0044] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0046] The following describes a floor brush assembly 100 and a cleaning device according to some embodiments of the present application with reference to FIG1 to FIG4 .

[0047] As shown in FIG1 , according to the first aspect of the present application, the present application provides a floor brush assembly 100, comprising a housing 110 and a roller brush 130 and a squeeze roller 140 provided on the housing 110, wherein the roller brush 130 is rotatable relative to the housing 110, and the squeeze roller 140 is rotatable relative to the housing 110, and the circumference of the roller brush 130 and the circumference of the squeeze roller 140 are in contact with each other, wherein the circumference of the roller brush 130 has fluff, and the squeeze roller 140 squeezes the fluff of the roller brush 130, and then after the fluff absorbs water, the squeeze roller 140 can press the water out of the fluff, thereby reducing the water content of the fluff on the roller brush 130, and then when the roller brush 130 cleans the surface to be cleaned, the possibility of water accumulation on the surface to be cleaned can be reduced, thereby improving the cleaning effect. The squeeze roller 140 and the roller brush 130 are interference fit, and the interference between the squeeze roller 140 and the roller brush 130 is between 4 mm and 6 mm.

[0048] The squeezing roller 140 is only arranged on the housing 110 via the bearing 150. That is, the squeezing roller 140 is arranged on the housing 110 via the bearing 150, which reduces the need for a bearing bush, so that the squeezing roller 140 is only subjected to rolling friction, making the squeezing roller 140 rotate more smoothly, reducing the resistance experienced by the squeezing roller 140, making the roller brush 130 rotate more smoothly, improving the stability of the squeezing roller 140, and improving the cleaning effect of the cleaning device.

[0049] Specifically, when the roller brush 130 rotates, under the action of friction, the roller brush 130 can drive the squeezing roller 140 to rotate, wherein the squeezing roller 140 and the roller brush 130 rotate in opposite directions.

[0050] The floor brush assembly 100 provided in the present application includes a shell 110, a roller brush 130 and a squeezing roller 140. The roller brush 130 and the squeezing roller 140 are both rotatably arranged on the shell 110, and the circumferential side of the squeezing roller 140 is in contact with the circumferential side of the roller brush 130. In addition, the squeezing roller 140 applies a pre-tightening force to the roller brush 130, so that the squeezing roller 140 squeezes the roller brush 130. Then, when the roller brush 130 rotates, the roller brush 130 can drive the squeezing roller 140 to rotate by friction, and then the squeezing roller 140 can discharge the liquid adsorbed by the fluff on the surface of the roller brush 130, so that the surface of the roller brush 130 is drier and the water collection on the cleaning surface is reduced.

[0051] In addition, the squeezing roller 140 and the roller brush 130 are both rotating, so there is rolling friction between the squeezing roller 140 and the roller brush 130. The rolling friction is low, which can reduce the damage to the fluff on the surface of the roller brush 130, improve the cleaning effect, and increase the service life of the roller brush 130.

[0052] The squeezing roller 140 may be made of plastic or metal.

[0053] Furthermore, the squeezing roller 140 is only arranged on the housing 110 through the bearing 150 , which can ensure that the squeezing roller 140 rotates more smoothly and improve the stability of the squeezing roller 140 .

[0054] As shown in FIG1 , as a possible embodiment of the present application, the housing 110 includes a housing body 112 and a bracket 114 . The bracket 114 is disposed on the housing body 112 . The squeezing roller 140 is disposed on the bracket 114 , and the squeezing roller 140 is rotatable relative to the bracket 114 .

[0055] In this embodiment, the housing 110 includes a housing body 112 and a bracket 114 . The bracket 114 is disposed on the housing body 112 , and the squeezing roller 140 is rotatably disposed on the bracket 114 , thereby facilitating the installation of the squeezing roller 140 and the housing 110 and reducing installation difficulty.

[0056] Specifically, the bracket 114 has a receiving groove on a side facing the roller brush 130 , and a portion of the squeezing roller 140 is disposed in the receiving groove, thereby improving the stability of the squeezing roller 140 .

[0057] As shown in Figures 3 and 4, as a possible embodiment of the present application, the shell 110 also includes an elastic member 116 arranged between the shell body 112 and the bracket 114. Specifically, one end of the elastic member 116 is connected to the shell body 112, and the other end is connected to the bracket 114. Then, under the action of the elastic member 116, the bracket 114 is pushed toward the roller brush 130, and then the bracket 114 drives the extrusion roller 140 to squeeze the roller brush 130.

[0058] In this embodiment, the shell 110 also includes an elastic member 116 arranged between the shell body 112 and the bracket 114. One end of the elastic member 116 is connected to the shell body 112, and the other end of the elastic member 116 is connected to the bracket 114. In addition, the elastic member 116 is in a pre-tightened state, thereby supporting the bracket 114, so that the bracket 114 and the squeezing roller 140 squeeze the roller brush 130. That is, through the setting of the elastic member 116, the squeezing effect of the squeezing roller 140 on the roller brush 130 can be ensured, so that the liquid on the roller brush 130 can be discharged more thoroughly.

[0059] Specifically, the elastic member 116 includes a mechanical spring, a gas spring or a hydraulic spring, etc. In addition, there can be multiple elastic members 116 , which are evenly distributed on the bracket 114 , so that the squeezing roller 140 squeezes the roller brush 130 more evenly.

[0060] The elastic member 116 can ensure that the squeezing roller 140 and the roller brush 130 have a fixed interference, thereby ensuring the water squeezing effect of the squeezing roller 140. The interference between the squeezing roller 140 and the roller brush 130 can be changed by the elasticity of the elastic member 116.

[0061] As shown in Figure 2, as a possible embodiment of the present application, the shell 110 also includes a comb tooth 118 arranged on the bracket 114, and the comb tooth 118 is arranged on one side of the squeezing roller 140, and the comb tooth 118 faces the roller brush 130. The comb tooth 118 can be in contact with the roller brush 130, or the comb tooth 118 can squeeze the roller brush 130, or the comb tooth 118 can have a smaller distance from the roller brush 130.

[0062] In this embodiment, the shell 110 also includes comb teeth 118, which are arranged on the bracket 114 and facing the roller brush 130, and the comb teeth 118 are arranged on one side of the extrusion roller 140. Therefore, when the roller brush 130 rotates, the comb teeth 118 can scrape off the debris on the roller brush 130, reducing the difficulty of cleaning the roller brush 130.

[0063] Specifically, the comb teeth 118 include a plurality of protruding teeth, which are arranged at intervals along the axial direction of the roller brush 130, so that the comb teeth 118 can catch hair, long threads and other debris on the roller brush 130, and when the roller brush 130 rotates, the hair, long threads and other debris can be pulled off the roller brush 130.

[0064] As shown in FIG. 2 , as a possible embodiment of the present application, the comb teeth 118 are located below the squeezing roller 140 . When the roller brush 130 rotates, the same position on the roller brush 130 first passes through the comb teeth 118 and then passes through the squeezing roller 140 .

[0065] In this embodiment, when the roller brush 130 rotates, it usually rotates from outside to inside, that is, the rotation direction of the position where the roller brush 130 and the squeezing roller 140 are in contact is upward. Therefore, the comb teeth 118 are arranged below the squeezing roller 140, so that when the roller brush 130 rotates, it can first pass through the comb teeth 118 and then pass through the squeezing roller 140. That is, before the squeezing roller 140 squeezes the roller brush 130, the debris on the roller brush 130 is scraped off first, making it easier for the debris to be scraped off by the comb teeth 118, reducing the difficulty of cleaning the roller brush 130, and reducing the possibility of debris being entangled on the squeezing roller 140, thereby improving the working stability of the squeezing roller 140.

[0066] As shown in Figure 2, as a possible embodiment of the present application, a liquid outlet 120 is provided on the bracket 114, and the port at one end of the liquid outlet 120 faces the roller brush 130, wherein the other end of the liquid outlet 120 can be connected to the water tank of the cleaning equipment, thereby spraying water to the roller brush 130, so that the roller brush 130 forms a mopping effect.

[0067] In this embodiment, the bracket 114 is provided with a liquid outlet, and a port at one end of the liquid outlet faces the roller brush 130, so that liquid can be sprayed toward the roller brush 130 through the liquid outlet to facilitate the cleaning effect of the roller brush 130 on the surface to be cleaned.

[0068] Specifically, one end of the liquid outlet 120 is arranged above the squeezing roller 140. When the roller brush 130 rotates, it usually rotates from outside to inside, that is, the rotation direction of the position where the roller brush 130 and the squeezing roller 140 are in contact is upward. Therefore, one end of the liquid outlet 120 is arranged above the squeezing roller 140, so that when the roller brush 130 rotates, it can first pass through the squeezing roller 140 and then pass through the liquid outlet 120. That is, after the squeezing roller 140 squeezes the roller brush 130, liquid is sprayed onto the roller brush 130, and then the surface to be cleaned can be cleaned with clean water, thereby improving the cleaning effect of the roller brush 130 on the surface to be cleaned and achieving a cleaning effect on the roller brush 130.

[0069] As shown in FIG. 2 , as a possible embodiment of the present application, a mounting groove is provided on the shell body 112 , and the bracket 114 is embedded in the shell body 112 .

[0070] In this embodiment, the bracket 114 is embedded in the shell body 112 , thereby improving the stability of the bracket 114 , better supporting the squeezing roller 140 , and reducing the possibility of the squeezing roller 140 tilting or separating from the roller brush 130 .

[0071] In addition, the elastic member 116 is disposed in the mounting groove, and the mounting groove serves as a guide to ensure that the squeezing roller 140 squeezes the roller brush 130 .

[0072] As shown in FIG. 1 , as a possible embodiment of the present application, the housing 110 includes a cantilever beam 122 , and a roller brush 130 is disposed on the cantilever beam 122 .

[0073] In this embodiment, the housing 110 includes a cantilever beam 122 , and the roller brush 130 is disposed on the cantilever beam 122 , thereby facilitating the roller brush 130 to clean corners.

[0074] Specifically, the cantilever beam 122 is disposed on the shell body 112 . By disposing the cantilever beam 122 , the cover on the shell 110 can be eliminated, so that the roller brush 130 can better clean the surface to be cleaned.

[0075] As shown in Figures 1, 2, 3 and 4, as a possible embodiment of the present application, the roller brush 130 is a cylindrical structure, the squeezing roller 140 is also a cylindrical structure, and the axes of the roller brush 130 and the squeezing roller 140 are roughly parallel, and the extension directions of the roller brush 130 and the squeezing roller 140 are the same, and the circumferential side of the roller brush 130 and the circumferential side of the squeezing roller 140 are in contact with each other.

[0076] In this embodiment, the roller brush 130 and the squeezing roller 140 are both cylindrical structures, and the axis of the roller brush 130 and the axis of the squeezing roller 140 are arranged roughly parallel, so that the circumferential side of the squeezing roller 140 can better fit the circumferential side of the roller brush 130, thereby improving the drainage effect of the roller brush 130.

[0077] As shown in FIG2 , as a possible embodiment of the present application, there are multiple squeezing rollers 140 , and the multiple squeezing rollers 140 can be arranged with their ends facing each other. Along the axial direction of the roller brush 130 , the multiple squeezing rollers 140 squeeze different positions of the roller brush 130 .

[0078] In this embodiment, there are multiple squeezing rollers 140. Along the axial direction of the roller brush 130, the multiple squeezing rollers 140 squeeze different positions of the roller brush 130, thereby reducing the length of the squeezing roller 140, reducing the possibility of deformation of the squeezing roller 140, and improving the squeezing effect of the squeezing roller 140 on the roller brush 130, thereby improving the squeezing effect of the squeezing roller 140 on the roller brush 130 without setting a bearing.

[0079] Specifically, the number of the squeezing rollers 140 may be two, three, or four, etc. Bearings 150 are provided at both ends of each squeezing roller 140 , and the ends of the plurality of squeezing rollers 140 are arranged opposite to each other.

[0080] Also, the entire length of the squeezing roller 140 may be slightly greater than, slightly less than, or equal to the length of the rolling brush 130 .

[0081] As shown in Figures 1, 2 and 3, as a possible embodiment of the present application, the floor brush assembly 100 also includes a plurality of bearings 150, and the squeezing roller 140 and the shell 110 are connected through the bearings 150. Specifically, bearings 150 are provided at both ends of the squeezing roller 140, so that the rotation of the squeezing roller 140 is more balanced.

[0082] In this embodiment, the floor brush assembly 100 further includes a plurality of bearings 150, and the squeezing roller 140 is disposed on the housing 110 via the bearings 150, thereby reducing the resistance of the squeezing roller 140 and the frictional force exerted on the fluff on the roller brush 130. When there are multiple squeezing rollers 140, at least one bearing 150 is disposed at both ends of each squeezing roller 140, thereby enhancing the squeezing effect of the squeezing roller 140 on the roller brush 130.

[0083] Specifically, the bearing 150 may be a roller bearing, a ball bearing, or a cylindrical bearing.

[0084] As shown in Figures 1, 2, 3 and 4, as a possible embodiment of the present application, the floor brush assembly 100 includes a squeezing roller 140, a roller brush 130 and a shell 110, and the shell 110 includes a shell body 112, a spring and a bracket 114.

[0085] The squeezing roller 140 is cylindrical and made of metal. It is embedded in the bracket 114 and has a bearing 150 at its end. The bearing 150 may be a rolling bearing. The squeezing roller 140 abuts the roller brush 130 with a certain interference fit (4 to 6 mm). The roller brush 130 rotates counterclockwise under the drive of the motor. The squeezing roller 140 rotates clockwise due to the friction of the roller brush 130, squeezing out the sewage adsorbed on the hair of the roller brush 130. The sewage can then be sucked away through the sewage suction port, which can be located on the housing 110.

[0086] That is, the floor brush assembly 100 provided in the present application transforms the sliding friction between the wiper strip and the roller brush 130 in the related art into rolling friction between the squeezing roller 140 and the roller brush 130, thereby reducing the wear of the roller brush 130 during use, thereby extending the service life of the roller brush 130;

[0087] Specifically, there are two squeezing rollers 140 , and bearings 150 are provided at both ends of each squeezing roller 140 , and the rollers 140 are fixed to the bracket 114 through the bearings 150 , thereby increasing the stability of the structure.

[0088] In addition, the housing 110 further includes a cantilever beam 122 , and the roller brush 130 is disposed on the cantilever beam 122 , which can realize a “double-edge” function of the roller brush 130 structure and improve the cleaning effect.

[0089] Optionally, comb teeth 118 are provided at the lower end of the squeezing roller 140 to achieve an anti-entanglement function. During the rotation of the roller brush 130, dirt first passes through the comb teeth 118, preventing hair, pet hair and other debris from being entangled in the structure of the squeezing roller 140, thereby improving the working stability of the squeezing roller 140.

[0090] Optionally, an elastic member 116 is provided at the rear end of the bracket 114. Under the action of the elastic force of the elastic member 116, the squeezing roller 140 and the roller brush 130 are always in abutment and maintain a fixed interference fit, further ensuring the water squeezing effect of the squeezing roller 140 on the roller brush 130.

[0091] The floor brush assembly 100 provided in the present application effectively alleviates the wear of the roller brush 130 caused by the scraping roller brush 130 adsorbing sewage by changing the friction form, ensures the water squeezing effect of the roller brush 130, reduces residual water stains on the ground, improves the cleaning effect of the roller brush 130, and extends the service life of the roller brush 130.

[0092] Furthermore, the use of a multi-segment squeezing roller 140 in conjunction with a bearing 150 structure increases system stability, reliability, and manufacturability, while also adapting to the "double-edge" functional structure of the roller brush 130 .

[0093] According to a second aspect of the present application, the present application provides a cleaning device, comprising: a floor brush assembly 100 as provided in any of the above embodiments.

[0094] The cleaning device provided in the present application includes the floor brush assembly 100 provided in any of the above embodiments, and therefore has all the beneficial effects of the floor brush assembly 100 provided in any of the above embodiments, which will not be stated one by one here.

[0095] Specifically, the cleaning device further includes a motor for driving the roller brush 130 to rotate.

[0096] Among them, cleaning equipment includes floor scrubbers or floor scrubbing robots.
