I have 4 cats and 1 room with carpet. I swear they specifically seek out the carpet to do all their nasty deeds. I comes this life saver! Learning to use it was super easy. It sucked up so much dirt! My room felt just like when I moved in. The air was clean, my carpet was white and it didn't even smell like cats. I also used it on my makeup chair which was very dirty with makeup. Literally saved me from buying a new chair
