Abstract

A motorized floor mop that can deliver liquid to a surface to be cleaned is provided with a handle, a base, a fluid delivery system, a motorized agitation system and a multi-axis swivel joint coupling the handle with the base for movement of the handle. A lock-out mechanism selectively locks out one of the axes of rotation of the multi-axis swivel joint.

a base connector pivotally coupled to the base and defining the first axis of rotation about which the handle can rotate in a front-to-back direction;

an upright connector pivotally coupled to the base connector and defining the second axis of rotation about which the handle can rotate in a side-to-side direction;

a first lock-out mechanism configured to selectively lock out movement of the handle about the second axis of rotation; and

a second lock-out mechanism configured to selectively lock out movement of the handle about the first axis of rotation.

5. The motorized floor mop of claim 4 wherein the second lock-out mechanism comprises:

a locking projection provided on the upright connector; and

a seat in the base configured to receive the locking projection in an upright storage position of the motorized floor mop;

wherein the motorized floor mop is self-supporting in the upright storage position.

6. A motorized floor mop, comprising:

an upright assembly comprising a frame, and a handle extending upwardly from the frame;

a base;

a fluid delivery system comprising a supply tank supported by the frame and a fluid distributor provided on the base and in fluid communication with the supply tank via a fluid delivery pathway;

a motorized agitation system, comprising;

a plurality of cleaning pads provided on the base; and

at least one drive motor operably coupled with the plurality of cleaning pads for rotation of the cleaning pads; and

a multi-axis swivel joint coupling the handle with the base for movement of the handle about a first axis of rotation and a second axis of rotation that is orthogonal to the first axis of rotation, the fluid delivery pathway extends at least partially through the multi-axis swivel joint, the multi-axis swivel joint, comprising;

a base connector pivotally coupled to the base and defining the first axis of rotation about which the handle can rotate in a front-to-back direction;

an upright connector coupled with a lower portion of the upright assembly and pivotally coupled to the base connector and defining the second axis of rotation about which the handle can rotate in a side-to-side direction; and

a lock-out mechanism configured to selectively lock out movement of the handle about the second axis of rotation.

7. The motorized floor mop of claim 6 wherein the lock-out mechanism comprises:

a spring-biased plunger operatively coupled with one of the base and the handle; and

a detent notch operatively coupled with the other of the base and the handle and configured to receive the spring-biased plunger.

8. The motorized floor mop of claim 7 wherein the lock-out mechanism further comprises:
