Query: Great purchase!

Great carpet cleaner. I went with this model after MUCH research b/c my parents bought the same one about 10 years ago and have NEVER had an issue with theirs. After borrowing theirs for 4 years, I decided that it was time to buy my own.Sometimes the vac doesn't suck- but that is b/c I don't always have the canister locked into place. With an infant and 2 large dogs...this was a great purchase and it does a wonderful job!
