This portable carpet cleaner will spray, brush, and suction up any stain, no adult supervision needed. It also comes with a hose and tool attachment if you'd prefer a more hands-on cleaning session.
Promising review:"I have two cats (ages 16 and 8), one dog, a 5-year-old kid, and several other dogs on occasion (I pet sit and board dogs). I have needed to rent a carpet cleaner at least twice a year since I can remember. No longer! The SpotBot has revolutionized cleaning in our household.It is ridiculously easy and fast!The best part is thatI barely have to touch anything gross anymore. I always pick up the larger chunks first, but I let the SpotBot do the rest and all I have to do is follow-it up with a good dump and rinse.A single spot takes less than five minutes to clean depending on the setting used and your competency (again, super easy to set up and use).I've had good experience on the stairs and the upholstery using the wand as well." —Rainbow Chicken
