Abstract

A window cleaning robot includes a main body including a top shell and a bottom shell. The top shell and the bottom shell define an internal space of the main body and the bottom shell includes a plurality of air inlets. At least two driving mechanisms are disposed between the two driving mechanisms. An air pump is disposed in the internal space and configured to extract air, through the inlets of the bottom shell, between the two driving mechanisms to create negative pressure to form a vacuum area located between the two driving mechanisms. An accommodating portion is configured to accommodate the air pump and an air tube, disposed in the internal space, includes an air inlet end coupled to an opening of the accommodating portion and an air outlet end coupled to an air exhaust opening toward the driving mechanism. The air inlet end of the air tube is configured to receive the extracted air and the extracted air is then exhausted toward the driving mechanism via the air tube and the air exhaust opening.
