Royal SE 2800 Hand-Held Spot Cleaner
My husband and I bought this machine shortly after we got our basset hound puppy and we regret spending the money.  It holds hardly any liquid, and when the tank gets full, the waste water sprays out of the vents on the side and gets all over you!  It's really disgusting.  It seems to me that with carpet cleaners, bigger is better.  If you plan on using a carpet cleaner a lot, like we do, go with a larger machine.  But whatever you do, DO NOT BUY THIS MACHINE!!!
