Hand-held surface cleaning apparatus
First Claim
1. A portable cleaner apparatus for cleaning a workpiece surface, the apparatus comprising:
- (a) a housing having a nozzle extremity, a suction opening being formed at the nozzle extremity and a suction passage extending within the housing and terminating at the suction opening;
(b) a motor drive supported by the housing;
(c) a brush member rotatably supported relative to the housing on a brush axis and operatively coupled to the motor drive, the brush member extending on the brush axis in a direction away from the housing beyond the nozzle extremity for selective engagement of desired circumferential portions of the brush member with the workpiece surface;
(d) a vacuum pump fluid connected to the suction passage for drawing unwanted material into the suction passage through the suction opening;
(e) supply means for holding a cleaning fluid;
(f) at least one fluid delivery passage for the cleaning fluid, the delivery passage being supported by the housing and having a fluid outlet proximate the suction opening;
(g) a pressure pump fluid connected to the supply means for selectively feeding the cleaning fluid through the delivery passage and from the fluid outlet; and
(h) collector means for receiving the unwanted material from the suction passage.

Abstract
Disclosed is a portable cleaner apparatus for cleaning a workpiece surface. The apparatus includes a housing having a suction opening at a nozzle extremity, a suction passage in the housing terminating at the suction opening; and a motor driven brush rotatably supported relative to the housing and axially projecting beyond the nozzle extremity for selective engagement of desired circumferential portions of the brush with the workpiece surface; a vacuum pump for drawing unwanted material into the suction passage through the suction opening. A supply container holds a cleaning fluid and is releasably held fluid connected to a supply passage by a supply support. At least one fluid delivery passage having a fluid outlet proximate the suction opening selectively applies the cleaning fluid to the workpiece surface. A pressure pump fluid connected to the supply means for selectively feeds the cleaning fluid through the delivery passage and from the fluid outlet. A collector for receiving unwanted material from the suction passage includes a receiver passage connected to the suction passage; a receiver support for releasably supporting a receiver container that is fluid connected to the receiver passage and fluid connected to the vacuum pump; and a separator for preventing the unwanted material from passing to the vacuum pump from the receiver passage. The apparatus can include a handle for manually manipulating the apparatus, and a feed control for selectively feeding the cleaning fluid.
