A floor scrubber is disclosed including a frame including a drive wheel, rear wheels, brushes, vacuum squeegee system, batteries, solution tanks, and an operator seat. The rear wheels are rotatably mounted on the opposite ends of a steel rod. Arms are attached rigidly to the axle and each include a cylindrical pivot in which an elastomer bushing is press fit. Pivot pins extend through first and second pairs of first and second plates and the elastomer bushing for pivotably mounting the arms to the frame while isolating any transmitted vibrations. Elastomeric isolator mounts are provided each including a frusto-conical shaped body and each having a nut embedded in the lower end for threadable receipt of a bolt passing through an attachment plate attached to the axle. The upper ends of the elastomeric isolator mounts each include a plate secured thereto and secured to the frame.

Machine for cleaning floors comprising, in combination: a frame; means attached to the frame for cleaning floors; an axle in the form of a rod and having first and second ends; first and second relatively rigid wheels each having an axial opening, with the axial openings of the first and second wheels being directly rotatably mounted on the axle adjacent the first and second ends; at least a first arm rigidly and directly attached to and extending from the axle, with the first arm including a free end; means for pivotably mounting the free end of the arm to the frame about a pivot axis parallel to but spaced from the axle and for isolating any transmitted vibrations from the wheels and the axle to the frame through the pivot axis; means for resiliently attaching the axle to the frame for restricting the pivotal movement of the arm relative to the frame and for isolating any transmitted vibration from the wheels and the axle to the frame through the resiliently attaching means; and a drive wheel attached to the frame spaced from the axle.
