A multi-surface cleaning apparatus is provided that includes a cylindrical dowel having an eccentrically-shaped body comprising first and second lobes. The body further comprises at least two arrays of differing sized bristle packets extending therefrom. The first array is configured for engaging a flat surface and the second array is configured for engaging a woven surface. First and second wheels are guided by a respective annular eccentric race formed by an inset and a boss in the race. The eccentrically-shaped body and the eccentrically shaped first and second races prevent the wheels from engaging a flooring surface when the first array is in contact with the floor and the eccentrically-shaped body and the eccentrically shaped first and second races allow the wheels to engage a flooring surface when the second array is in contact with the floor.

A treatment element for attachment to a wash media element includes a tab portion for engaging and effecting attachment to the wash media element. A treatment head is connected to the tab portion and is configured to engage a vehicle exterior. The treatment head including a plurality of individual finger portions that are moveable with respect to one another.

The invention relates to a mounting device for a drum (2) consisting of at least two joined drum segments (21, 22) as a part of a shaft (1) of a brush roller, said mounting device including an internal circumferentially directed shoulder (24) being a part of a first drum segment (21) and an external circumferentially directed shoulder (23) being a part of a second drum segment (22), said two shoulders (23, 24) are provided with cooperating contact surfaces mainly positioned in a circumferential or tangential direction with respect to a complete drum (2), the external shoulder (23) being provided with a radial directed clearance hole intended to involve a screw (30), the threaded end of which being directed into the geometrical rotation axis of a complete drum, whereby the interior circumferentially directed shoulder (24) is provided with a recess (26) having a bottom (25) and an opening (27) facing the geometrical rotation axis and the recess (26) is designed with plain inner side surfaces (42, 43) facing each other and being parallel and axial with respect to the drum, and the recess (26) is equipped with projections (28) tangentially and circumferentially originating from each one of said side surfaces and pointing to each other. Furthermore the invention relates to a drum segment, a drum, and a brush roller with such a mounting device.
