ROBOT VACUUM

摘要

A robot vacuum comprises a vacuum body provided to be movable and a suction unit provided to be movable relative to the vacuum body in the vertical direction, wherein the suction unit comprises a suction hole through which foreign materials are suctioned from a surface to be cleaned, and at least one support unit provided so as to separate, at a fixed interval, the suction hole and the surface to be cleaned. The configuration can improve the efficiency of the suctioning of foreign materials from the surface to be cleaned, and can maintain the interval, between the suction unit and the surface to be cleaned, at a fixed interval.
