Surface treating head
First Claim
1. A surface treating head comprising a main body;
- a suction cavity in the main body comprising first and second suction channels, each of which is bounded on at least one side by a working edge configured to agitate a carpeted surface to be treated when the surface treating head is maneuvered over that surface;
an outlet;
a fluid flow path in the suction cavity between the first and second channels and between the second channel and the outlet;
a brush unit; and
a drive mechanism for moving the brush unit between a stowed position and a deployed position, wherein part of the brush unit extends over the upper surface of the main body.

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.
