<p>A vacuum cleaner has a hose and wand assembly (2a, 2b, 38), onto which a floor tool may be attached. The wand (38) comprises a plurality of telescoping tubes (39,- 40, 41) which can slide between retracted and extended positions. In order to be able to transmit power and signals from the vacuum cleaner to the end of the wand assembly, conductors (4, 5, 6) are provided in a channel (3a) in the hose. The hose (2a) is connected to the interior of the wand, just beyond the last telescoping joint, with the conductors extending beyond the end of the hose to a connector (48) at the far end of the wand. This arrangement automatically provides a reliable electrical connection down the wand. Previously, electrical conductors were not employed with this type of wand as it was not straightforward to provide electrical connections across the telescoping parts.</p> |
