I vacuum a 3,000 sq. ft. dog training center every day and have tried several other machines. It's a pricey machine but well worth the cost. I used to purchase a new vacuum every 6 or 7 months because we burned them out, not this one! This is they only one for us. I keep one as "back up" but haven't had to use it for the last 3 years. Love this machine. Best price I've seen, delivery was prompt and in good condition.
