My Wet/Dry vac is a Home Depot Bucket Head 5 Gallon. It's a vacuum motor that clips onto a 5 gallon bucket. It's $20 at Home Depot plus the $5 or so for the bucket, as the bucket is sold separately. It's top heavy, so you can't drag it around that easily and the hose is stiff. It's good for cleaning cars and sawdust.
