Background

Currently, a cleaning machine is a floor washing machine, a dust collector or a floor sweeping machine, which sucks a mixture of dust and the like mixed with water vapor on the floor into a sewage tank thereof.

The existing floor washing machine and dust collector usually need to be pushed by a user to clean, but because the cleaning parts of the floor washing machine and dust collector need to be fully contacted with the ground to achieve a good cleaning effect, the friction force between the cleaning parts and the ground can require larger pushing force on the floor washing machine, and the user is more laborious to operate. In order to solve the problem of laborious operation of users, a power assisting mechanism is additionally arranged in a cleaning product in the prior art, so that pushing operation is more labor-saving. Chinese patent application of cleaning device
