Abstract: Vibration dampening elements that are made of rubber and/or an elastomer may fail when subjected to vertical and/or horizontal stresses caused by repeated lifting of the cleaning head assembly and/or unintentional bumping of the cleaning head assembly into door frames, walls or other non-movable objects. The present invention includes, among other things, at least one stabilizer element and preferably two stabilizer elements to reduce damage to certain vibration dampening elements caused by vertical and/or horizontal stress. Alternative embodiments of the stabilizer element are also disclosed.

Abstract: This orbital motion scrubber uses less cleaning solution than many conventional rotary motion scrubbers of comparable scrub width and tank size, which results in longer solution run time. The present invention drives the cleaning element in a high speed orbital motion which results in more revolutions per spot than many conventional rotary motion scrubbers. A flexible pad driver produces better cleaning of uneven hard surface floors than some prior art designs with rigid pad drivers. The brush motor that drives the pad driver and the cleaning element of the present invention uses less electrical energy than the brush motor in many rotary motion scrubbers which results in longer battery run time.
