Zusammenfassung: | The present invention provides a vacuum cleaner control system comprising: a first user-operable control (30) for switching a suction source (14) of said vacuum cleaner between an on condition and an off condition; a second user-operable control (32) for switching a rotatable brush (24) in a floorhead (22) of said vacuum cleaner 5 between an on condition and an off condition; a third user-operable control (34) for switching a filter cleaning mechanism (20) for cleaning a filter (18) of said vacuum cleaner between an on condition and an off condition; a detector (38) for detecting when a handle (12) of said vacuum cleaner is tilted between a substantially vertical, storage position and an angled, use position; and an electronic circuit (40) for 10 receiving input signals from said first, second and third user-operable controls (30, 32, 34) and from said detector (38), said electronic circuit (40) having a first output for switching said suction source on and off, a second output for switching said floorhead brush on and off and a third output for switching said filter cleaning mechanism on and off. In a preferred embodiment, the vacuum cleaner control system further 15 comprises a display (36), and the electronic circuit (40) further comprises an output for driving said display, and said display comprises an input for receiving said output from said electronic circuit.
