Floor polishing and washing device for e.g. hospital, has suspension between coupling unit and plate, and recesses coinciding with supports to allow pellets passage so that working surfaces of pellets and disk are coplanar in usage position

摘要

The device has an elastic suspension (2) between a working plate (3) and a coupling unit (1) coupling the plate to a rotating head of a cleaning machine. The plate has coupling units (31) and supports (32) to respectively fix a washing disk and polishing pellets. The disk has recesses (51a) coinciding with the supports to permit passage of the pellets so that working surfaces of the pellets and disk are coplanar in utilization position.
