摘要

The mobile wet-cleaning machine has at least one tank (12) for the cleaning-fluid (15) which is conveyed through an outlet (32) in the tank to at least one driven cleaning-tool (7). A suction-foot (8) sucks up the cleaning fluid from the floor area cleaned and is returned to the tank. The dirt particles are separated from the cleaning fluid by a tubular filter arrangement (31, 38) consisting of a micro or ultra-filtration membrane. Between the tank-outlet and the filter-inlet is a preliminary filter (38) for coarse particles and which has a mesh-width of at most 0.3 millimetres, preferably 0.1 millimetres. At least one pump (39) of adjustable output is between the tank outlet and filter inlet. USE/ADVANTAGE - The cleaning cycle is lengthened of the wet cleaning machine is lengthened, and the cleaning fluid more easily discharged at the end of the cleaning cycle.
