## Abstract

A power assisted device for cleaning toilet bowls includes an elongated stem portion having a brush at the distal end thereof, and a spray outlet port proximate to the brush. The brush is joined to a reciprocally rotating shaft extending through the stem to provide agitation to the brush. At the proximal end of the stem, a housing includes a pump connected between a liquid cleanser tank and a tubing extending from the pump to the spray outlet. The housing includes rechargeable batteries to drive the pump and a motor assembly which drives the brush.

## Claims

### Claim 1

A power assisted cleaning device, comprising a portable housing, a stem assembly joined to said housing in freely reciprocating fashion, a cleaning brush secured to the distal end of said stem assembly, motor means disposed in said housing for driving said stem assembly in reciprocating rotary motion, a spray jet disposed adjacent to said brush, liquid reservoir means in said housing for holding a cleaning solution therein, pump means in said housing and connected between said reservoir and said spray jet for pumping liquid cleaning solution to said spray jet, rechargable battery means disposed within said housing for energizing said pump means and said motor means, wall bracket means for supporting said device, said bracket means including recharging means for recharging said battery means, said wall bracket means including a wall-mounted bracket having a tapered slot extending generally vertically therethrough and adapted to receive a like tapered portion of said portable housing therein, said stem assembly extending downwardly therethrough in suspended fashion, said wall mounted bracket including electrical contacts projecting therefrom and disposed to contact recharging contacts on the exterior of said portable housing.

### Claim 2 (depends on 1)

The device of claim 1, wherein said pump means includes a flexible delivery tube extending from said housing through said stem assembly to said spray jet.

### Claim 3 (depends on 1)

The device of claim 1, further including switch means mounted on said housing for selectively actuating said pump and said motor means.

### Claim 4 (depends on 1)

The device of claim 1, wherein said brush includes bristles extending outwardly therefrom over a continuous surface extending approximately 180.degree. and disposed generally symmetrically with respect to the axis of said stem assembly.

### Claim 5 (depends on 4)

The device of claim 4, wherein said spray jet is disposed among said bristles and is directed outwardly therefrom.

### Claim 6 (depends on 1)

The device of claim 1, wherein said stem assembly includes a shaft rotatably secured in said housing, and a cam arm extending radially from said shaft.

### Claim 7 (depends on 6)

The device of claim 6, wherein said motor means includes a gear reduction assembly connected to the output thereof, said gear reduction assembly including an eccentric arm extending from a rotating portion thereof and engaging said cam arm to drive said cam arm in reciprocal rotation.

### Claim 8 (depends on 1)

The device of claim 1, further including external port means in said housing for refilling said reservoir means.

### Claim 9 (depends on 1)

The device of claim 1, further including a handle hole extending entirely through said portable housing and configured to permit manual gripping of said device.
