Carpets look good, but they don't recommend necessary vacuuming once they dry. I would recommend it. I have a dog and crawling baby and do not want either of them breathing in the dried "crystals" or getting them on their skin- could be a serious irritant. My vacuum canister filled up with fibers and crystals 12 hours later. There is a slight chemical smell when done too. Overall, I'm happy with my fresh clean carpets, but might try conventional steam cleaning next time to compare.
