Exactly... For residential, I wouldn't want the bigger ones. I've been eyeballing this little guy for quite a while but always ended up with other equipment purchased. (turbohybrid, Dwellpro, RV 360XL, etc) it's time for me to get this guy as I run into more and more of this crushed matted junk that really needs this type of scrubbing.
First time I almost bought a little unit like that was back in 2008 in Greenie's garage..he wanted to get rid of it along with a WhiteTragic tm... I didn't buy either of those..
