摘要： A mobile surface cleaner 100 has a mobile body 102 configured to travel to areas to be cleaned. A dispensing system 103 attached to the mobile body 102 dispenses liquid on a surface 104 as dispensed liquid. A recovery system 105 attached to the mobile body 102 recovers dispensed liquid as recovered liquid 124. A regenerative media filter 148 attached to the mobile body 102 filters the recovered liquid 124 to form filtered liquid 152 that can be dispensed by the dispensing system 103.
