Abstract
A vacuum tank with a rear door, and air and material hoses connectable to the tank door. The tank is rotatable, while the door remains stationary. Liquid, particulate, or slurry material can be vacuumed into the rotating tank, without twisting the hoses. Additional water and/or drying agent can be added to the tank to create a slurry mixture, which can then be discharged from the tank at a convenient dump site. The tank may be mounted on a truck or trailer for transport to a job site and a dump site.
