The all steel construction is really rugged, the performance is excellent and the giant filters and 2-stage disposable bags keep operating efficiency high. The accessory kit with its extra long hoses, stainless steel tube sets and superb tools is second to none. What you don’t get, however, is the noise! By virtue of the outstanding “low noise” specification this is probably the quietest machine of its type setting an entirely new commercial standard. Accessory Kit: Many other Accessory kits and Accessories are available for boiler cleaning, vehicle cleaning, etc.
