Abstract
A motor-driven endless absorbent belt on an apparatus may be used for scrubbing or polishing surfaces, or removing liquid from surfaces. The belt is located about a cleaning head demountable from a housing for replacement of the belt, a roller mounted to the head and cooperating with a roller mounted to the housing to squeeze liquid and contaminants from the belt into a first reservoir in the housing. A driven roller mounted on the removable cleaning head preferably encloses a rotary motor, the belt being pinched between the driven roller and the housing-mounted roller.

A cleaning apparatus for cleaning a surface, comprising :
- a housing holding a first reservoir;
- a housing-mounted roller mounted to the housing;
- a cleaning head releasably coupled to the housing;
- a plurality of head-mounted rollers mounted on the cleaning head;
- drive means operatively connected to at least a driven one of the head-mounted rollers for rotation of the driven head-mounted roller, and
- an endless absorbent belt supported for rotation about the head-mounted rollers, wherein,
- in an operating position the belt is pinched between the housing-mounted roller and one of the head-mounted rollers to squeeze liquid and contaminants from the belt into the first reservoir, and
- the cleaning head is movable relative to the housing from the operating position to a released position in which the belt is released from between the housing-mounted roller and the one of the head-mounted rollers to remove the belt.

- drive means operatively connected to at least a driven one of the head-mounted rollers for rotation of the driven head-mounted roller, and
- an endless belt supported for rotation about the head-mounted rollers, wherein,
- in an operating position, the housing-mounted roller deflects the belt from a line tangential to two adjacent head-mounted rollers to tension the belt, and
- the cleaning head is movable relative to the housing from the operating position to a released position in which the belt tension is released to remove the belt.
