Abstract
The present disclosure relates to a battery powered floor cleaner. The floor cleaner is operable in various modes based on the capacity of a battery pack, such as a normal power mode and a low power mode.
Claims11
A floor cleaner comprising:
- a base having a suction inlet;
- a handle coupled to the base, the base movable along a surface to be cleaned by a user manipulating the handle;
- a suction source configured to generate an airflow through the suction inlet;
- a liquid distribution system including a supply tank connected to a fluid distributor configured to deliver solution to the surface;
- a recovery tank in fluid communication with the suction source configured to store the solution drawn through the suction inlet from the surface to be cleaned by the suction source;
- a battery pack configured to supply power to the suction source and the liquid distribution system;
- a sensor configured to sense a characteristic of the battery pack indicative of a remaining capacity of the battery pack, the characteristic selected from a group consisting of current, voltage, and power;
- a controller operatively connected to the battery pack, the suction source, and the fluid distributor, the controller including an electronic processor and a memory, the controller configured to:
- receive from the sensor the characteristic of the battery pack indicative of the remaining capacity of the battery pack,
- operate the floor cleaner in a first mode when the remaining capacity of the battery pack is greater than a first threshold,
- operate the floor cleaner in a second mode when the remaining capacity of the battery pack is greater than a second threshold and less than the first threshold, and
- interrupt operation of the floor cleaner when the remaining capacity of the battery pack is less than the second threshold.
9 more elements
A method of operating a floor cleaner comprising:
- supplying power to a suction source and a liquid distribution system from a battery pack;
- distributing solution from the liquid distribution system onto a surface to be cleaned;
- recovering the solution into a recovery tank in fluid communication with the suction source through a suction inlet;
- determining a remaining capacity of the battery pack;
- comparing the measured remaining capacity with a first threshold value,
- operating at least one of the suction source and the liquid distribution system in a first mode when the remaining capacity is greater than the first threshold value,
- operating at least one of the suction source and the liquid distribution system in a second mode when the remaining capacity is less than the first threshold value and greater than a second threshold;
- and
- interrupting operation of the floor cleaner when the remaining capacity of the battery pack is less than the second threshold.
