After reading all the positives about the machine I decided to get one. I went to my local Lowes and got the Spot Clean version, as it was the only one on the shelf.
Used it today on what I thought was a clean floor mat, guess not as it pulled out all kinds of nasty stuff. I used the included cleaners for this, but I'll probably switch to just hot water after they run out.
The only negative is how little dirty water it collects before needing to be emptied, guess that's what you give up for $100.
So far I like the unit.
