Patent attributes
A cleaning apparatus includes an elongated housing bounding a chamber with a motor disposed therein. A drive shaft is at least partially disposed within the chamber of the housing, the drive shaft being coupled with the motor such that during selective operation of the motor the drive shaft is rotated continuously. A brush head has a plurality of bristles mounted thereon. A hub is disposed on the brush head and has an elongated channel bounded by a pair of spaced apart engagement surfaces. A spherical head is disposed within the channel so as to selectively bias against the engagement surfaces, the spherical head being eccentrically disposed on the drive shaft such that the spherical head reciprocally rotates the brush head when the drive shaft is continuously rotated.
