Abstract
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. A head assembly includes an elongated head housing having a head drive shaft and a brush head mounted thereon. The head assembly is adapted to be selectively coupled with the body assembly so that the body drive shaft is coupled with the head drive shaft.
Claims19
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;
- 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 about a rotational axis thereof;
- and
- a gear assembly disposed between the motor and the body drive shaft, the gear assembly increasing the torque produced on the drive shaft by the motor by a ratio in a range between about 1.5:1 to about 3.5:1;
- 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;
- and
- a carrier plate having a rotational axis about which the carrier plate rotates, the carrier plate being coupled with the head drive shaft such that rotation of the head drive shaft facilitates rotation of the carrier plate, the rotational axis of the carrier plate intersecting the rotational axis of the head drive shaft so as to form an inside angle greater than 95°, the inside angle remaining constant during rotation of the carrier plate, 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;
- and
- a cleaning element secured to the carrier plate.

A cleaning system kit 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;
- 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 about a rotational axis thereof;
- and
- a gear assembly disposed between the motor and the body drive shaft, the gear assembly increasing the torque produced on the drive shaft by the motor by a ratio in a range between about 1.5:1 to about 3.5:1;
- (ii) a first head assembly comprising:
- a first head housing;
- a first head drive shaft disposed within the first head housing and having a rotational axis about which the first head drive shaft rotates;
- and
- a first carrier plate having a rotational axis about which the first carrier plate rotates, the first carrier plate being mounted on the first head housing and being coupled with the first head drive shaft such that rotation of the first head drive shaft facilitates rotation of the first carrier plate, the rotational axis of the first carrier plate intersecting the rotational axis of the first head drive shaft so as to form an inside angle greater than 95°, the inside angle remaining constant during rotation of the first carrier plate, the first head assembly being adapted to be selectively coupled with the body assembly so that the body drive shaft is coupled with the first head drive shaft;
- and
- a first cleaning element secured to the first carrier plate;
- and
- (iii) a second head assembly comprising:
- a second head housing;
- a second head drive shaft disposed within the second head housing and having a rotational axis about which the second head drive shaft rotates;
- and
- a second carrier plate having a rotational axis about which the second carrier plate rotates and having a configuration that is different than the first carrier plate, the second carrier plate being mounted on the second head housing and being coupled with the second head drive shaft such that rotation of the second head drive shaft facilitates rotation of the second carrier plate, the rotational axis of the second carrier plate intersecting the rotational axis of the second head drive shaft so as to form an inside angle greater than 95°, the inside angle remaining constant during rotation of the second carrier plate, the second head assembly being adapted to be selectively coupled with the body assembly so that the body drive shaft is coupled with the second head drive shaft;
- and
- a second cleaning element secured to the second carrier plate.
