An upright vacuum cleaner has a universal joint arrangement 31 between the cleaner body 10 and a nozzle unit 20. Manipulation of the hand 11 by a user, twisting to one side, may cause the nozzle unit 20 to turn in the same direction. A variety of outrigger wheel arrangements to the joint arrangement 31, including some with flexing wheel arm supports, may also be provided |
