I started with and currently clean the majority of my homes with the RDM. I bought a titanium wand and pimped it out with the latest greatest. I still prefer the RDM, and I think it flushes better and is easier to clean with once you get it going. Yes, it is heavy and lugging it in and out of the truck is the downside. The wand is faster, but your still stroking the floor as the downside. I use both but the wand is secondary and is useful for the small houses and apartments. In case you haven't heard of it, the greenie stair tool is the one to have when it comes to doing stairs.
