Abstract
An apparatus having utility for cleaning large, non-horizontal surfaces such as walls. A generally planar head is adapted to be oriented in a generally vertical manner during use, such that it will have a top, bottom, two sides, and front and rear surfaces. A fibrous pad is sized to cover a substantial portion of the front surface of the head. The pad is selectively removable from the head; but during use the pad is firmly held against the friction forces that are imposed on it by moving the head across the surface being cleaned. A plurality of reservoirs, a conduit, and a pump are provided for supplying a selected cleaning or rinsing liquid at a controlled rate to the top of the head. A low-pressure chamber adjacent the rear of the head is used to collect arty liquid that: has passed through the fibrous pad. A resilient seal around the sides and the bottom of the head is effective to inhibit the leakage of liquid from around the boundaries of the head for as long as the head is maintained upright and as long as a pressure lower than atmospheric is maintained in the chamber. An elongated handle is used by an operator to support the head during cleaning. An open-top tub with supporting casters is used to support and transport the apparatus at a job site.
