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, which may be further enhanced by an air duct, in the form of a slot, which draws air over some of the working edges. The invention permits a tool with a lower profile to be manufactured than would be achievable by providing separate flow paths between the respective channels and the outlet.
