Outer wall cleaning robot.

摘要

An outer wall cleaning robot includes an arm (14) pivotable about a first rotation axis (I) and a rotational body (15) supported by the arm for pivotal movement about a second rotation axis (II). The rotational body can be driven independently of a pivotal movement of the arm. To the rotational body are attached respective mounting mechanisms (17, 19) for a wiping squeegee (18) and a receiving squeegee (20).
