Abstract

Provided is a window cleaning machine including a body, air extracting module, first cleaning device, second cleaning device, walking module disposed near the body, and driving device connected to the first and second cleaning devices to cause a reciprocating motion thereof. The body defines a primary suction space. The air extracting module is disposed on the body and is in communication with the primary suction space. The first and second cleaning devices are each in contact with a pane surface while performing a cleaning operation. The first cleaning device defines a first subsidiary space in communication with the primary suction space. The second cleaning device defines a second subsidiary space in communication with the primary suction space. The walking module is disposed outside the first and second subsidiary spaces. The window cleaning machine undergoes the reciprocating motion across a non-horizontal pane surface while clinging firmly thereto by suction.
