I have a bissell carpet cleaner, it just uses hot water. It was about $250 when I got it 5 years ago. The carpet shampoos are expensive but excellent. I use the special for pets one, safe for pets and gets rid of pet smells and pet germs. I use very hot tap water in the cleaning mix and it works well.

you can just spot clean with it too , no need to do the whole house

also I do rugs with it , just have to do it on a tiled section in the house

in the long run it has been worth every penny and does a great job.

the one I got is now 299, that's the one you want
