Abstract
A floor cleaner having a recovery tank, a suction source, and a filter basket. The suction source is configured to generate an airflow along a fluid flow path to draw fluid and debris from a surface to be cleaned into the recovery tank. The recovery tank has an outlet duct on a tank body. The filter basket is positioned in the outlet duct on the tank body and configured to filter debris from the airflow.
Claims20
A floor cleaner comprising:
- a fluid flow path extending from a suction nozzle to a clean air outlet;
- a recovery tank in the fluid flow path, the recovery tank in fluid communication with the suction nozzle and including a tank body, a tank inlet, a tank air outlet, and an outlet duct upstream of the tank air outlet;
- a suction source in fluid communication with the suction nozzle and the recovery tank, the suction source configured to generate an airflow through the fluid flow path to draw fluid and debris from the surface to be cleaned through the suction nozzle and into the recovery tank;
- and
- a filter basket positioned in the outlet duct, the filter basket including a first end, a second end downstream of the first end, and a sidewall extending between the first end and the second end,
- wherein the first end is open enabling ingress of debris and the sidewall of the filter basket has perforations allowing air flow to pass through the filter basket and inhibiting debris from passing through the filter basket.
