The Scheppach SprayVac20 spray and wash vacuum cleaner requires a 20 litre steel waste water tank for wet vacuuming. This container is part of the appliance and is used to collect the suctioned dirty water.
Hands off this appliance - it really is just rubbish! The water pump on the first appliance was defective from the start. After replacing it with a new appliance, the washing/suction result was so miserable - I gave the appliance away.
