The Multiwash Floor Cleaning Machine works well on awkward profile floors and tiles, rubber, wood, and carpet. It is especially effective in cleaning tile grout and non-slip floors. The Multiwash gives outstanding results – in a single pass – on most types of hard floor surfaces leaving wood, PVC, studded rubber, marble, granite, stone, quarry-tile, profiled ceramic floors, and non-slip safety floors ready to walk on in minutes. – No hard pushing, pulling, or lifting is required as the machines are incredibly maneuverable and extremely light to handle. – Cylindrical brush system provides deep scrubbing at 650 rpm – over 3 times higher than rotary brush scrubbers and 4 times more contact pressure for superior cleaning. – Counter-rotating brushes and recovery drum clean and clear debris in one pass. – Self-cleaning brushes – no messy pads to worry about and brushes far outlast pads. – Eco-friendly low moisture cleaning uses 30% less chemical and water providing increased savings. – Whisper quiet 69 dB level for day cleaning and noise sensitive application. * For use on commercial (direct glue) carpet. The Multiwash is NOT for use on carpet with a pad.
