I work in a banquet hall with two large dining rooms and several smaller meeting rooms. All rooms are carpeted and each room hosts various activities throughout the day, seven days a week. A few years ago a former GM bought a pair of Dysons in addition to the two Sanitaires he was already using for double the price. We threw away the Dyson after a few months because both broke. To be honest, these Dysons were probably intended more for home use. However, at my workplace for the past 10+ years, we have used and abused sanitaires before and after every event. I recently bought two of these to replace two that finally ran out of breath and expect them to last just as long, if not longer. If you work in an industry that requires frequent vacuuming, you'll be glad you chose Sanitaire. Pros: Quality parts, strong suction yet easy to use, bag shaking system (no need for disposable bag), great value for money. .Cons: The noise level can be higher than other home vacuum cleaners.
