This is a Kodak brand A2K antistatic negative cleaner. I bought it about 10-11 years ago and used it off an on since. I don't know if it really does what it claims to. It buzzes and the brush wipes film, but that is all I know. I never tried a different one to compare results. It is heavy, maybe 15 pounds (7 kilos), so shipping may be a little high for it's size. Mounts to the wall.
