Query: Poor suction, big disappointment

I don't understand why this machine is rated "commercial" - it is TINY, the suction is terrible, and the floor attachment is difficult to manuever. The "bare floors to carpet" option is a joke - it's impossible to push on carpet; the small fibers on the attachment grip the carpet and don't allow it to move! I bought it to use in my retail store space and returned it after one use. We have old hardwood floors that we clean pretty regularly but had hitherto only swept. I expected a commercial vacuum to provide some power but this one failed big time - I had to move very slowly and go back and forth repeatedly to pick up dust bunnies that any household vacuum would grab the first time. I would have been better off getting a Shop-Vac for around $20.
