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;
an outlet; and
a fluid flow path in the suction cavity extending from the first suction channel to the second suction channel, and from the second suction channel to the outlet, wherein each suction channel is bounded by a front working edge and a rear working edge, the head comprising an air through the main body duct, open to the atmosphere, interposed between the first and second suction channels for conveying air towards the rear working edge of the first suction channel and towards the front working edge of the second suction channel and into the suction channels.

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.
