A cleaning system comprising a vacuum source, a current sensor, a recovery tank having a shutoff float configured to float on a surface of fluid within the recovery tank, and a controller. The vacuum source is in fluid communication with a suction inlet via first and second air paths within the recovery tank. The shutoff float is further configured to block the first air path upon the fluid within the recovery tank reaching a desired level. The controller is configured to receive, from the current sensor, a signal indicative of the current drawn by the vacuum source. The controller is further configured to determine, based on the current drawn by the vacuum source crossing a threshold, the fluid within the recovery tank has reached the desired level and control an operating element of the cleaning system upon determining the fluid within the recovery tank has reached the desired level.

Full recovery tank shutoff

A cleaner including a base defining a suction chamber, a brush roll driven by a brush roll motor, a sensor configured to sense a parameter related to a floor; and a controller having a memory and electronic processor. The controller is configured to receive the parameter, control the brush roll motor based on the parameter and a first floor coefficient, determine a second floor coefficient based on the parameter, and control the brush roll motor based on the second floor coefficient.
