A travelling apparatus for cleaning the surface of swimming pools has a wide profiled belt, with one end beneath the surface and the other over a filter, to remove the soil.

摘要

The belt (1) lies at an angle to the water surface and is driven in a direction that lifts floating debris and deposits it in a filter pan (2). Propellers (3) drive and steer the machine through the water and a sensor (4) and control system (5) allow the entire surface to be covered.
