Hello, please refer to the video of the air scrubber and pressure washer connection in the link below. The pneumatic scrubber is connected to the high-pressure cleaner with a 3/8 quick connector. As long as the parameters of the high-pressure cleaner meet the working requirements of the pneumatic scrubber, it is not limited to any brand of high-pressure cleaner. So yes, this works for a ryobi 2000w 2200psi.
