Abstract: An automatic cleaning device includes a mobile platform, a lifting station, a cleaning module, a liquid supplying module, and a collecting module. The mobile platform is configured to automatically move in a target direction on a surface to be cleaned. The lifting station is connected to the mobile platform and configured to move upwards or downwards with respect to the mobile platform. The cleaning module is connected to the lifting station and configured to clean the surface to be cleaned; the liquid supplying module is configured to provide cleaning liquid to the surface to be cleaned; and the collecting module is configured to collect the cleaning liquid. A height of the cleaning module of the automatic cleaning device is adjustable, and the automatic cleaning device has a great cleaning strength and is capable of collecting dirty cleaning liquid, thus, the automatic cleaning device can be applied broadly.

Abstract: A main housing provides a first reservoir and a second reservoir. Water flows from the first reservoir to the second reservoir. A draining aperture in the first reservoir directs water from the first reservoir to the second reservoir. The water may be flushed from the first reservoir to the second reservoir. In another embodiment, the water may flow directly from the first tank to the second tank without the flush. A pump circulates water from the second reservoir to the first reservoir. The pump directs the water through a filtration system to filter the water to remove at least some of the dirt, debris, and other contaminants from the water. The filtered water is then returned to the first reservoir. An overflow relief in a dividing wall of the first reservoir directs overflow water to the second reservoir.
