SELF-PROPELLED CLEANING DEVICE Russian patent published in 2023 - IPC A47L9/00 A47L5/00 A47L11/02 A47L7/00 

FIELD: cleaning devices.

SUBSTANCE: group of inventions relates to self-propelled cleaning devices. The self-propelled cleaning device contains a base; a mobile module adjacent to the base and made with the possibility of contact with the surface when the self-propelled cleaning device moves along the surface; a vacuum module located above the base; a dust collector located above the base and connected to a vacuum module, wherein the dust collector contains the first hole and the second hole, where the area of the first hole is larger than the area of the second hole, and the first hole is directed in the first direction other than the second direction in which the second hole is directed; the first suction port located on the base and containing the first suction inlet connected to the first hole where the first suction port does not contain bristles or brush blades; a second suction port located on the base and containing a second suction inlet connected to the second hole, with the first suction port located between the front side of the base and the second suction port, where the second suction port is adjacent to the first suction port; a set of first locking sheets located between the first suction inlet and the second suction inlet and protruding outward from the base for contact with the surface when the self-propelled cleaning device moves over the surface where the first locking sheets are separated; a brush-roller device located on the base and in the second suction port; and an air duct, in this case, the first suction port is connected to the dust collector through an air duct to connect the first suction inlet to the first hole.

EFFECT: expansion of the range of cleaning devices.
