摘要： A scrubbing device is provided including a body which is supported on a plurality of wheels which are driven by a hydraulic pump. The scrubbing machine has a squeegee which is hydraulically raised and lowered. The machine is provided with a sensing device adjacent the hydraulic drive pump which senses the flow of the hydraulic fluid and actuates valving to raise the squeegee upon reverse movement of the scrubber and lower the squeegee upon forward movement of the scrubber.

摘要： An improvement for floor maintenance equipment employing electrically driven scrubbing or polishing brushes including means for varying the speed of the brush motors. Two brush speeds are provided by switching apparatus which change the interconnection of the brush motors from series to parallel and from parallel to series. This results in a substantial change in motor speed and power.
