Abstract
A cleaner head for a cleaning appliance includes a dirt and dust separating apparatus, a motor configured to drive a fan for generating suction air flow and a selectively-operable switch for energizing the motor and cleaner head. The cleaner head has a drivable agitator in the form of a brush bar and a dedicated motor. When the main vacuum motor is switched on, the brush bar motor is energized so that the brush bar is automatically driven on start-up of the cleaner. This enables the superior cleaning performance achievable with a brush bar to be automatically achieved, without the user having to remember to select operation of the brush bar.

A cleaner head for a cleaning appliance comprising a dirt and dust separating apparatus, a motor configured to drive a fan for generating suction air flow and a control circuit comprising a selectively-operable switch for energizing the motor, the cleaner head comprising
- a driveable agitator configured to be automatically driven each time a user switches on the motor and capable of being de-energized while the motor is energized subsequent to thus being automatically driven, the control circuit being configured to reset the driveable agitator each time the motor is turned off and switched on such that the driveable agitator is automatically driven each time the user switches on the motor.
A cleaning appliance comprising
- a main body housing a dirt and dust separating apparatus,
- a motor configured to drive a fan for generating suction air flow,
- a control circuit comprising a selectively-operable switch for energizing the motor, and
- a cleaner head having a driveable agitator configured to be automatically driven each time a user switches on the motor and capable of being de-energized while the motor is energized subsequent to the agitator thus being automatically driven, the circuit being configured to reset the driveable agitator each time the motor is turned off and switched on such that the driveable agitator is automatically driven each time the user switches on the motor.
A control circuit for a cleaning appliance comprising a dirt and dust separating apparatus, a motor arranged to drive a fan for generating suction air flow and a cleaner head having a driveable agitator which is capable of being de-energized while the motor is energized, the circuitry comprising
- a user-operable switch for energizing the motor, the circuitry being configured to reset the driveable agitator each time the motor is turned off and switched on such that the driveable agitator is automatically driven each time a user switches on the motor.
