<p>A surface treating head in the form of a floor tool(10) for a vacuum cleaner comprises a main body (12), a suction cavity (20) and an outlet (34). The suction cavity (20) comprises first and second suction channels (22, 24), bounded on both sides by respective working edges (40, 42, 44, 46). A fluid flow path (56) extends from the first suction channel (22) to the second suction channel (24) and from there to the outlet (34). 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 (48), which draws air over some of the working edges (42, 44). 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.</p> |
