Abstract

The present invention relates to an automatic vacuum cleaner. According to an aspect of the present invention, the automatic vacuum cleaner includes a first movement part and a second movement part capable of together moving along an inclined cleaning surface, a movement unit provided in at least one of the first movement part and the second movement part, a cleaning member provided in at least one of the first movement part and the second movement part, and a detection unit which detects states of the cleaning surface, wherein movement speeds of the first movement part and the second movement part are varied according to the states of the cleaning surface.

Claims

1. An automatic vacuum cleaner, comprising:

a first movement module configured to move along a first surface of a panel, including when the panel is inclined;

a cleaner provided in the first movement module;

at least one fixed suction provided on a main body of the first movement module;

a first suction motor to provide a negative pressure to the fixed suction;

a plate rotatably coupled to the main body, the plate having first and second grooves;

a first driving motor that rotates the plate;

a first movable suction configured to move along the first groove based on an operation of a second driving motor; and

a second movable suction configured to move along the second groove based on an operation of a third driving motor,

wherein a second suction motor provides a negative pressure to the first movable suction and a third suction motor provides a negative pressure to the second movable suction.

2. The automatic vacuum cleaner according to claim 1, further comprising a controller to control movement of the plate, the first movable suction, and the second movable suction and to control negative pressure to the fixed suction, the first movable suction, and the second movable suction, wherein the vacuum cleaner moves along the first surface of the panel.

3. The automatic vacuum cleaner according to claim 2, further comprising a second movement module capable of moving along a second surface of the panel.

4. The automatic vacuum cleaner according to claim 3, wherein the first movement module communicates operation methods to the second movement module using a communication module.
