- 1 - A B S T R A C T CLEANING APPARATUS A wheeled trolley (11,12) supports a removable back-pack unit (35,36) containing a motor drive (37,39) and a fluid pump (38). The motor (37) drives the pump (38) to draw fluid from a canister (32) and supply the fluid via flexible hoses (62,63, 64, 65) to a rotary brush unit (57,58,59). The motor rotates the brush via a flexible drive line (61) running from an output (39) on the back-pack to an input (56) on the brush handle (57). The trolley body (11) and back-pack casing (35) co-operate to retain the back-pack on the trolley in a readily removable manner. The canister (32) is likewise readily removable. The fluid supply and the motor electrical supply both run independ- ently of the trolley. The back-pack can therefore be used as such, at locations remote from the trolley, or can remain on the trolley to function as a power pack for the apparatus. The brush (59) may be a cylindrical brush and two different formats (66,83) are disclosed.
