Abstract
A surface treating head in the form of a floor tool for a vacuum cleaner includes a main body, a suction cavity and an outlet. The suction cavity includes first and second suction channels, bounded on both sides by respective working edges. A fluid flow path extends from the first suction channel to the second suction channel and from there to the outlet. The plurality of suction channels permits effective pick-up of dirt. To enable the surface treating head to be used to treat both carpeted floor surfaces and hard floor surfaces, the surface treating head may be provided with a brush unit and a drive mechanism for moving the brush unit between a stowed position and a deployed position.
