I use the cimex for residential and I've only had one unhappy customer (they really wanted extraction). I have a procaps CRB machine as well but I didn't get it with a tank so I prefer the cimex because otherwise I have to do the extra step of spraying solution. For stairs I either spray and use the zebra brush or use a cimex pad or cotton bonnet with green stripe on the drill driver.
