I have 2 Shop-Vac brand units - one is the 'old school' orange shop-vac that you should probably wear jet aircraft hearing protection for. The newer one is one of their quiet models (QSP model?) and is just a bit louder than our home vac. It's actually a pleasure to use compared to the other one. Funny thing is the old one has worked all along, the new one went kaput after maybe 3 or 4 years. I called them, explained what was going on, completely expecting the old " I'm really sorry to hear about that, but your unit is out of warranty " pitch - instead they asked for my address and Fed-Exd a new motor unit to my door the next day. Sure, it should not have broken, but they stood by it and made it right. I give them very high marks for customer service, and wouldn't hesitate to buy another.
As for a blower feature, the 1st unit has that - and compared to a dedicated leaf blower it's performance is pathetic. If you need a blower just buy a separate unit.
