摘要

The floor cleaner has an absorbent endless belt (1) which passes over a system of rollers (2 - 4) before contacting the floor. Liquid is squirted into it through a perforated roller (5), so that dirt is transported to its outer surface. It is then squeezed between rollers (3, 6) so that the dirty liquid falls into a trough (9). The endless belt does not contact the liquid in the trough.
