Module surface cleaning mechanism

The embodiment of the utility model provides a modular surface cleaning mechanism, and relates to the field of modular surface cleaning. The modular surface cleaning mechanism comprises a base plate and a plurality of dust collection units, wherein the dust collection units are movably mounted on the base plate; wherein the dust collection unit comprises a brush and a dust collection bin, the brush is detachably arranged in the dust collection bin, part of the brush is located outside the dust collection bin, and the brush and the dust collection bin are used for moving to the outer side of the base plate at the same time to conduct sweeping and dust collection operation. When the modular surface cleaning mechanism is used, the multiple dust collection units can move to the outer side of the base plate at the same time to conduct cleaning and dust collection operation, the problem that in the prior art, due to the fact that the position of a dust collection bin is fixed, metal chippings fall off is solved, th
