SUMMARY OF THE INVENTION
In accordance with one embodiment of the present invention, a hand held motorized household cleaning apparatus is provided having a housing, a battery located in the housing, a motor located in the housing, and a cleaning section connected to a drive shaft of the motor. The connection between the drive shaft and the cleaning section provides linear reciprocating motion of the cleaning section.
In accordance with another embodiment of the present invention, a hand held cleaning apparatus is provided comprising a housing, a battery located in the housing, a motor located in the housing, and a movable cleaning section connected to the motor. A drive transmission is provided between the motor and the movable cleaning section that provides at least two alternative types of motion of the cleaning section. The at least two types of motion are at least partially different from one another.
In accordance with another embodiment of the present invention, a hand held scrub brush is provided comprising a housing, a battery, a motor, and a cleaning section. The battery is located in a handle of the housing. The motor is located in the housing and is electrically connectable to the battery. The cleaning section is connected to the motor by a drive transmission. The drive transmission provides an orbital motion of the cleaning section.
