Patent ID: 8267607

Claim:
A surface working apparatus, comprising: a main shaft; a handle coupled to the main shaft, and having a trigger mounted thereto; a cleaning head coupled via a coupling device to one end of the main shaft in a fashion enabling contact with a surface to be cleaned, the cleaning head comprising a leading edge and a trailing edge; a canister holder attached to the main shaft, and configured to hold a canister containing a cleaning solution, wherein a nozzle end of the canister is exposed through a front end of the canister holder; and an actuator functionally coupled on one end of the trigger, and positioned at a front end of the canister holder on an opposite end, such that movement of the trigger is configured to functionally engage the actuator thus liberating the cleaning solution from the canister; wherein the cleaning head includes a smooth concave bottom surface sufficiently long to create a gap between the cleaning head and the surface to be cleaned; wherein the smooth concave bottom surface is flexible such that the gap is collapsed when a force is applied to the main shaft; wherein the concave bottom surface is concave in a first direction across the bottom surface and substantially flat in a second direction across the bottom surface, the first direction being perpendicular to the second direction; wherein in a surface cleaning position the main shaft extends upwardly behind and away from the coupling device at an angle with respect to a surface to be cleaned, the trailing edge is positioned beneath at least one of the main shaft and canister holder, and the leading edge is positioned in front of the coupling device such that the coupling device is positioned between the leading edge and trailing edge; and wherein in the surface cleaning position, the canister holder is configured to position a substantial portion of the nozzle end of the canister in front of the leading edge of the cleaning head.
