ABSTRACT:
The present invention relates to a cleaning robot system of a satellite type. The present invention provides a cleaning robot system of a satellite type that includes a flat autonomous cleaning head, a hose assembly, and a cleaning main body. The flat autonomous cleaning head includes a suction inlet formed in a bottom thereof, a side connector communicating with the suction inlet, travel wheels provided on both side thereof, and variable speed drive motors for driving the travel wheels. The hose assembly is connected to the cleaning head and is at least partially flexible. The cleaning main body is connected to the hose assembly and includes a vacuum pump, a dust collector, a discharge air separator, a power supply, and a controller. Since the cleaning head of the cleaning robot system according to the present invention has a simple structure, it is possible to make the cleaning head thin. Further, since the cleaning robot system has high output of power and high vacuum sucking performance, it is possible to satisfactorily clean the house. Furthermore, the cleaning robot system can perform wet cleaning by ejecting steam, hot water, and wash water, unlike a disk-shaped robot cleaner. Therefore, the cleaning robot system can satisfactorily perform all kinds of cleaning options that can be performed by a manual cleaner. In addition, the cleaning robot system can have a self-washing function to perform self-washing.
