CLEANING ROBOT

摘要

PURPOSE: A cleaning robot is provided to reduce cleaning hours and to improve cleaning efficiency by having enlarged suction port. CONSTITUTION: In a cleaning robot, a suction unit(300) includes a first and a second suction member(310,320), a first and a second brush(330,340), a driving unit(350) rotating one of the brushes, and a couple of bevel gears(361,362). The first brush and the second brush are rotatably installed at the first suction member and the second suction member, respectively. The bevel gears are installed at the ends of the brushes and are engaged with each other to transmit rotary force from one brush rotated by the driving unit to the other brush.
