Embodiment Construction

[0031] The extractor cleaner 1 shown in FIG. 1 has a housing 2 . The housing is composed of an upper case 49 and a lower case 50 . Two front wheels 18 are rotatably fastened to the housing. On the housing 2 of the vacuum cleaner 1 there is provided a connecting piece 17 for connection to the suction device of the vacuum cleaner.

[0032] FIG. 2 shows a sectional view of the suction cleaner. As shown in FIG. 2 , front wheels 18 may also be provided at the front side of the housing 2 . A suction hole 4 is formed in the lower case 50 . The suction opening extends over the entire width transversely to the working direction of the suction cleaning machine 1 . The suction hole 4 is a slit-shaped design. A cleaner, ie a brush roller 8 , is mounted rotatably about an axis of rotation 9 above the suction opening 4 . On this brush roller 8, many bristles 28 are fixed. Transversely to the working direction and parallel to the axis of rotation 9 of the brushroll 8, the housing 2 is...

Abstract

The suction cleaner has a housing (2) with a connecting piece (17) for connection to a suction device of the suction cleaning device. The suction cleaner has a suction hole (4) through which the working airflow flows into the housing (2); and a discharge hole (15) through which the working airflow leaves the housing (2) . The suction cleaner has a cleaner which is rotatably supported in the casing (2) and has a drive device for driving the cleaner to rotate. Good cleaning results and up to turbine power Good fit to different floor conditions. The method for operating the suction cleaner provides that the drive power of the cleaner is controlled as a function of the pressure (p) in the suction cleaner.

Description

technical field [0001] The invention relates to a suction cleaner having a housing with a connecting piece for a flow connection to a suction device of a suction cleaning device; A hole through which the working air flows into the housing; a discharge hole through which the working air leaves the housing; a cleaner which is rotatably supported in the housing; An air turbine for driving the cleaner in rotation, wherein the air turbine is rotatably mounted in a turbine chamber. [0002] The invention also relates to a method for operating an extraction cleaning machine. Wherein, the suction cleaning machine has a housing with a connection nipple for flow connection with a suction device of a suction cleaning device; a suction hole through which the working air flow flows into the housing body; a discharge hole through which the working air flow leaves the housing; a cleaner, which is rotatably supported in the housing; and also has a driving device for driving the cleaner to r...
