The Bucket Head wet/dry vac attaches directly to a standard 5-gallon plastic bucket (not included) to make an inexpensive shop vac for your home or garage. Reversing the hose allows the vacuum to double as a blower. The Bucket Head wet-dry vac is available at The Home Depot.
About the shop vac bucket, its dangerous.
It says not to vacuum up hazerdous stuff. Well all dust is hazardous to the lungs. Many people are going to be cleaning up pressure treated wood or plywood that has wicked Chemicals put in them. The vacuum power is good, the bad thing is if you hold the bucket up in sunlight you can see all the smaller dust going strait though it and into the air all over the place. This is a lawsuit waiting to happen.
