Provided is a cleaning robot system and a method of controlling the same for economically cleaning, with high workability, plate-shaped members, such as solar cell panels and reflecting mirrors used in photovoltaic power generation and solar thermal power generation systems. A cleaning robot system () for cleaning planar or curved plate-shaped members (), () that are panels for photovoltaic power generation or reflecting mirrors for solar thermal power generation includes: a large number of cleaning robots () each having a function to travel on each of the plate-shaped members () which are to be cleaned and a function to clean the plate-shaped members (); and an arranging robot () having a conveying function to move any of the cleaning robots () from a first one () of the plate-shaped members to a second one () of the plate-shaped members. Each of the cleaning robots () has a suction mechanism for performing cleaning while attaching onto one of the plate-shaped members (), and the large number of cleaning robots () and a smaller number of the arranging robots () than that of the cleaning robots () cooperate together to clean the plate-shaped members () placed in a photovoltaic power generation or solar thermal power generation plant.
