Abstract

A floor tool for use in vacuum cleaning floor surfaces includes a sole plate that has a suction channel formed in it. The suction channel is bounded on at least one side by a working edge for engaging with the floor surface. Lint pickers are positioned alongside the suction channel and are separated from the suction channel by the working edge. The lint pickers are mounted on a surface of the floor tool which is inclined with respect to the plane in which the working edges lie. The sole plate is pivotally mounted with respect to a suction outlet so that movement of the floor tool in a forward and backwards direction alternately brings one of the working edges into closer contact with the floor surface.

Claims

1. A floor tool for use in vacuum cleaning floor surfaces, comprising a sole plate comprising a suction channel, the channel being bounded on front and rear sides by two continuous working edges extending the width of the floor tool and lying in a common plane, the working edges lying adjacent corresponding lower faces of the sole plate which are inclined with respect to the plane in which the working edges lie, and lint pickers mounted on the lower faces, each lint picker being positioned alongside the suction channel and separated from the suction channel by its corresponding working edge, wherein the working edges are configured so as to alternatively engage with and agitate a floor surface across their full widths.

2. A floor tool according to claim 1, wherein the suction channel extends across the tool transversely to the direction in which the tool is configured to be pushed across the floor surface.

3. A floor tool according to claim 1, wherein the lint pickers are mounted on supports which project outwardly from the inclined lower faces.

4. A floor tool according to claim 3, wherein the supports are arcuately shaped.

5. A floor tool according to claim 1, wherein the sole plate is pivotally mounted with respect to the suction outlet such that movement of the floor tool in a forward and backwards direction alternately brings one of the working edges in closer contact with the floor surface.

6. A floor tool according to claim 1, 2 or 5, wherein the working edges are angular edges.

7. A floor tool according to claim 6, wherein each working edge has a radius of curvature substantially equal to 0.2 mm.

8. A floor tool according to claim 1, 2 or 5, wherein the lint pickers extend across more than one third of the width of the suction channel.

9. A floor tool according to claim 7, wherein the lint pickers extend across substantially one half of the width of the suction channel.

10. A floor tool according to claim 8, wherein the lint pickers extend across substantially the full width of the suction channel.
