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.
