I've owned quite a few of these mighty mites! I use to have a cleaning business and they worked awesome! I still have the original one from probably over 10 years ago. It's just starting to leak thru, where the motor is glued to the canister, but it doesn't owe me a thing. I definitely got my money's worth. Don't forget I was cleaning hair salons that were 10,000 sq ft, 4 days a week. Plus other salons too.
