Abstract
A floor cleaner includes a recovery tank including an inflow path allowing liquid-laden air to enter the recovery tank, an outflow path allowing air to exit the recovery tank; and a chamber for storing liquid. The chamber includes an inlet, a separator that separates liquid from the liquid-laden air, an air outlet, and a float. The float includes a base and a valve with an indicator. The float is moveable between a first position and a second position. In the first position the valve is spaced away from the air outlet and air is allowed to exit the chamber. In the second position the valve is adjacent the outlet and impedes air from exiting the chamber. In the second position the indicator is visible when the chamber is full.

A floor cleaner comprising:
- a recovery tank including,
- an inflow path allowing liquid-laden air to enter the recovery tank;
- an outflow path allowing air to exit the recovery tank;
- and
- a chamber for storing liquid including,
- an inlet;
- a separator that separates liquid from the liquid-laden air;
- an air outlet;
- and
- a float including a base and a valve with an indicator, the float movable between a first position with the valve spaced away from the air outlet, allowing air to exit the chamber and a second position with the valve adjacent the air outlet, impeding the air from exiting the chamber, wherein the indicator is visible when the chamber is full.
A floor cleaner comprising:
- an inlet;
- an outlet;
- a suction source operable to generate a suction airflow through the inlet and the outlet;
- a fluid flow path extending from the inlet to the outlet;
- a recovery tank positioned in the fluid flow path and including a recovery tank inlet and a recovery tank outlet;
- and
- a float that obstructs the recovery tank outlet in a closed position of the float in response to a fluid level in the recovery tank, wherein the float includes an indicator visible when the float is in the closed position to indicate to the user that the float is in the closed position.
