A rotary push broom provides a geometry between the centerline of the broom's wheels and the centerline of the broom's cylindrical brush that allows the vertical height of the cylindrical brush relative to that of the wheels to be adjusted as the frame rotates. The broom includes a support stand that allows the broom to be stored in a way that does not put the broom's weight on the brush. The broom also includes a ratchet gear system so that the broom rotates along with the wheels when the broom is operated in a forward sweeping direction and spins independent of the wheels when the broom is operated in a rearward direction. The gear system should be arranged so that the cylindrical brush rotates slower than the wheels in the sweeping direction. The support stand can be integrated with an endplate that accommodates the wheel connection and ratchet gear system.

Provided are a floor brush assembly for a vacuum cleaner and the vacuum cleaner. The floor brush assembly includes a roller brush component and a driving mechanism. The roller brush component includes a sleeve and a roller brush body rotatably mounted in the sleeve. The roller brush body is provided with bristles. The driving mechanism includes a power source and a transmission component. The transmission component includes a first driving member, a second driving member, and a driving wheel connected to the power source. The driving wheel is connected to the first driving member through a transmission shaft to drive the roller brush body to rotate. The driving wheel is connected to the second driving member through a linkage structure to drive the sleeve to rotate. The first driving member and the second driving member are eccentrically arranged to allow the bristles to be selectively extended out of or retracted into the sleeve.

A wash apparatus for a vehicle wash installation is provided, which includes a shaft drivable in rotation about a rotation axis and wash elements operatively connected thereto. In order to be able to adapt to the contour of a vehicle, the wash apparatus can be divided axially in two or more wash apparatus segments and that the at least one wash apparatus segment includes a wash element holding body having wash elements held thereto, said wash element holding body defining a wash apparatus segment axis which is different from the rotation axis, and a gear device which couples the shaft to the wash element holding body in order to rotate same about the wash apparatus segment axis, wherein the wash element holding body is configured for pivotal movement relative to the shaft via the gear device. Furthermore, a vehicle wash installation including a wash apparatus is provided.

A cleaning device 50 for cleaning a removable dental appliance 12 is described. The device 50 comprises a rotatable upper cleaning brush 14 comprising a plurality of downwardly protruding bristles 16 for cleaning an upper surface of a removable dental appliance. The device also comprises a lower dental appliance holder 18 for holding the dental appliance 12 and which is used in connection with the rotatable upper cleaning brush 14 to limit movement of the dental appliance 12 relative to the rotatable upper cleaning brush 14 wherein, in use, a cleaning action can be applied to the dental appliance 12 by rotating the rotatable upper cleaning brush 14 relative to the dental appliance. The cleaning device 50 further comprises a casing connector 30 for temporarily rotatably interconnecting the rotatable upper cleaning brush 14 and the lower dental appliance holder 18 so as to form a single integrated unit when assembled.

Embodiments of the present application provide for a roller device that includes a housing, a handle coupled to the housing, and a drum that is disposed within the housing and rotatably coupled to the housing. The roller brush further includes a debris collection cavity, an elastic member, and a scraping end. The debris collection cavity is disposed adjacent to a rear portion of the drum. The elastic member includes a first end and a second end, where the first end is coupled to the housing. The scraping element is disposed in the housing and is coupled to the second end of the elastic member. The scraping element includes a rotating shaft coupled to the second end of the elastic member and extends tangentially relative to the drum.
