The vacuum cleaners are produced in Europe to the highest standards. They have a 2-speed motor, with a secondary duct for cooling (2 years' guarantee). The long pipes are in light aluminium, covered with plastic to ensure perfect adherence and prevent rust. WS2 operates with the discharge system. It has a support hook for every 8.5 mt of conductor wire. The nylon filter is optional (ref. 312 for WS22 and WS35, ref. 499 for WS72). The paper filters are available but are not essential.
