Abstract:
1. A vacuum cleaner, comprising a head and a ball for contacting the ground and a body, wherein the ball is coupled to the body or to the head, wherein the body is pivotable relative to the head about a first axis of rotation and about a second axis of rotation, wherein the body has a locking mechanism and the head has a reciprocal locking mechanism, wherein the locking mechanism and the reciprocal locking mechanism are configured such that the locking mechanism is engageable with the reciprocal locking mechanism, thereby resisting pivotal movement of the body relative to the head about the first axis of rotation, wherein the locking mechanism is disengageable from the reciprocal locking mechanism by pivotal movement of the body relative to the head, thereby allowing pivotal movement of the body relative to the head about the first axis of rotation, and wherein the locking mechanism and the reciprocal locking are located inside the ball.
