<p>A canister vacuum cleaner comprising a main body and a wand 14 that telescopes between retracted and extended positions. The wand 14 and the main body comprise mounting features 21, 22, (23, fig 6) that engage to mount the wand 14 to the main body when the wand 14 is retracted, whilst preventing the wand 14 mounting to the main body when the wand 14 is extended. The wand 14 preferably comprises an inner tube 17 moveable relative to an outer tube 18, a first mounting feature 21 provided on the inner tube 17 and a second mounting feature 22 provided on the outer tube 18 with a third mounting feature (23, fig 6) being provided on the main body. The wand 14 is mounted to the main body by engagement of both the first 21 and second 22 mounting features with the third mounting feature (23, fig 6) when the wand 14 is in its retracted position but when the wand 14 is in its extended position only one of the first 21 and second 22 mounting features engage the third mounting feature (23, fig 6). The first 21 and third (23, fig 6) mounting features engage to permit movement of the wand 14 relative to the main body in a first direction and prevent movement in a second direction and the second 22 and third (23, fig 6) mounting features engage to prevent movement in the first direction and permit movement in the second direction.</p> |
