  • Patent number: 12004705
    Abstract: 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.

  • Patent number: 11839349
    Abstract: 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.

  • Publication number: 20220104671
    Abstract: A cleaning system (100) including a body (105), a motor (140) supported by the body (100), a sensor (325) configured to sense a characteristic of the motor (140), the characteristic selected from a group consisting of current, voltage, and power. The system (100) further includes a controller (305). The controller (305) is connected to the motor 140 and the sensor (325). The controller (305) includes an electronic processor (330) and a memory (335). The controller (305) is configured to receive, from the sensor (325), a signal indicative of the characteristic of the motor (140), determine, based on the signal, an integral of the signal over time, and operate the motor (140) based on the integral of the signal over time.
