Abstract
A surface cleaner includes a suction source that generates a suction airflow to draw liquid-laden air along a fluid flow path from a dirty air inlet to a recovery tank. The recovery tank includes a chamber for storing liquid, an inlet along the fluid flow path, an outlet aperture along the fluid flow path, and a float having an indicator. An inflow path upstream of the inlet connects the dirty air inlet to the recovery tank. The float moves between a first position spaced away from the outlet aperture allowing air to exit the recovery tank along the fluid flow path, and a second position adjacent the outlet aperture obstructing the fluid flow path. The indicator is visible to a user when the float is in the second position.

A surface cleaner comprising:
- a suction source operable to generate a suction airflow to draw liquid-laden air along a fluid flow path from a dirty air inlet to a recovery tank;
- the recovery tank including
- a chamber for storing liquid,
- an inlet along the fluid flow path,
- an outlet aperture along the fluid flow path, and
- a float having an indicator;
- and
- an inflow path upstream of the inlet connecting the dirty air inlet to the recovery tank;
- wherein the float is movable between a first position spaced away from the outlet aperture allowing air to exit the recovery tank along the fluid flow path and a second position adjacent the outlet aperture obstructing the fluid flow path;
