I'm in the process of gathering money to go from my bagless Riccar unit to a bagged MD. Right now I have an RPU-C10 Riccar, 2 motor 240v unit, going to an MD M965h2, another 240v dual motor unit (I have a thing for dual motor units...) largely to go with bags, but I also found there's an even more powerful motor I can use to replace the factory ones with, so it'll really have some suck to it! I have the Riccar P/N too, but I am also getting a Wessek Werk EBK360 to use on my QuickClick hose.
