The Multiwash will wash, mop, scrub and dry in a single pass on virtually every kind of floor. The compact MW240 (24cm cleaning width/1.2 litre tank) is useful for those difficult to reach locations. The MW340 (34cm cleaning width/1.7 litre tank) is available in two options, either with the standard 1.7 litre tank or with the larger 4 litre tank if larger areas are to be cleaned. The version with the tank feeds the water through a pump and is a must if you are going to use this machine for carpet cleaning. The MW440 version has the tank and pump assembly fitted as standard.
