  • the vacuum cleaner 100 may include a lock which inhibits rearward tilting of the upright section 1 10 when the upright section 110 is in the storage position.
  • the cleaning head 120 includes a lock release control 204 which may be pressed to disengage the lock and permit the upright section 1 10 to tilt rearwardly into the in-use position.
  • the lock may disengage automatically when the upright section 1 10 is pulled towards the in-use position with a sufficient amount of force.
  • the coupling portion 130 may include a detent plate which a support member engages when moved to the storage position. A threshold amount of force may be required to disengage the detent plate to obtain free the rearward tilting of the upright section 1 10.

As exemplified in FIGS. 2 and 3, the upright section 1 10 can pivot sideways without changing the rearward inclination angle 220, without twisting the upright section 110 and without turning or otherwise moving the cleaning head 120.
  • the rearward tilt and sideways pivot of the upright section 1 10 may be interrelated.
  • the sideways pivoting of the upright section 1 10 may be inhibited when the upright section 1 10 is in the storage position (as exemplified in FIG. 1 ) and uninhibited when the upright section 1 10 is in the in-use position.
  • the lock release control 204 may be configured to both unlock the rearward tilting and the sideways pivoting of the upright section 1 10.
