Patent ID: 7614107

Claim:
A cleaning apparatus comprising: (i) a body assembly comprising: an elongated body housing having a chamber; a motor at least partially disposed within the chamber of the body housing; and a body drive shaft at least partially disposed within the chamber of the body housing, the body drive shaft being coupled with the motor such that during selective operation of the motor, the body drive shaft is rotated continuously about a rotational axis thereof, and (ii) a head assembly comprising: an elongated head housing; a head drive shaft disposed within the head housing and having a rotational axis about which the head drive shaft rotates; a brush head comprising a carrier plate having a plurality of bristles secured thereon and having a rotational axis about which the brush head rotates, the brush head being mounted on the head housing and being coupled with the head drive shaft such that continuous rotation of the head drive shaft facilitates reciprocating rotation of the brush head, the rotational axis of the brush head intersecting the rotational axis of the head drive shaft so as to form an inside angle therebetween in a range between about 110° to about 140°, the inside angle remaining constant during reciprocating rotation of the brush head, the head assembly being adapted to be selectively coupled with the body assembly so that the body drive shaft is coupled with the head drive shaft.
