Abstract
A surface cleaning apparatus comprises a first flexible electrified air flow conduit having an air inlet end that is electrified.
Claims18
A surface cleaning apparatus comprising:
- (a) a surface cleaning head comprising a dirty air inlet, a brush and a rotatable brush motor;
- (b) air flow path extending from the dirty air inlet to a clean air outlet and including an air treatment member and a suction motor;
- (c) a main electrical switch coupled to an external power source;
- and,
- (d) a switching circuit operable in a first mode wherein power is supplied to the suction motor and the rotatable brush motor and the switching circuit is also operable in a second mode wherein power is supplied to the suction motor but not the rotatable brush motor,
- (e) the rotatable brush motor having a first end and an opposing second end, the rotatable brush motor being connected to a first diode on the first end and to a second diode on the second end, the first diode and the second diode being connected in series with the rotatable brush motor to provide a series combination, and the series combination of the first diode, the rotatable brush motor and the second diode being connected in parallel with the external power source.
