Abstract
An autonomous coverage vacuum cleaner includes a transmission element driven to rotate and disposed at the bottom of a body, and an edge cleaning head. The transmission element has a lower surface, a positioning recess denting upward from the lower surface and having a non-circular inner profile, and a fixing hole disposed in the positioning recess. The edge cleaning head includes a body, at least a brush extending from the body, a positioning block disposed on the body, and resilient elements extending upward from the positioning block. An outer profile of the positioning block corresponds in shape to the inner profile of the positioning recess. Under an applied force, the resilient elements deform resiliently, get closer to each other, and engage with the fixing holes. The positioning block engages with the positioning recess of the transmission element, such that the transmission elements drive the edge cleaning head to rotate.
