A trolley for carrying cleaning materials includes a main trolley structure having a front end, a rear end, and a pair of sides, front wheels at the front end, back wheels at the rear end, a housing, and a handle structure at the rear end for guiding the main trolley structure over a floor on the wheels. The handle structure is moveable from a stowed condition to an operating condition for guiding the trolley. A bucket structure includes a container for containing cleaning liquid and at least three wheels for stables moveable over the floor independently of the trolley. The housing has a space into which at least a part of the bucket structure may be wheeled from the front end or a side of the pair of sides, such that the bucket structure is substantially within the housing when the bucket structure is received by the space.
