I purchased the portable carpet cleaner after seeing a video online of someone cleaning their car seats. I bought one and have gone a little nuts with deep cleaning anything I can! I've cleaned my mattress, my car seats, rugs! It cleans so well and it's so easy to use. I've told anyone that cares to listen (and even some who don't, haha) about how amazing this is. It's probably the easiest purchase I've ever made.
