Cleaning devices

Abstract

The present disclosure provides a cleaning device. The cleaning device may include a machine body, a cleaning liquid tank, and a floor brush, wherein the floor brush may be connected to an end of the machine body, the cleaning liquid tank may be arranged above the floor brush, and the cleaning liquid tank may be configured to provide cleaning liquid for the floor brush or floor. When a user uses the cleaning device for cleaning work, the user may hold the machine body to control a moving direction of the floor brush. In the cleaning device, by setting a cleaning liquid tank on the floor brush, a volume and weight of the machine body can be reduced, which reduces an overall volume and weight of the cleaning device, thereby reducing a load and weight when the user operates the machine body and improving experience of the user during cleaning work.
