If you want a super vacuum to vacuum large dibries, sharp objects and dirty wet liquid, get this monster unit. We use it in a very large dealership and mechanics use it all day long to clean cars, engines, shop floors and to detail and wash cars after they fix them. the cart makes it to move easily and the tank is super large. The suction can vacuum screws and bolts from the shop floors and mechanics even vacuum oil from the floor and still no problem. The motor is mounted on top so it is protected from liquids and hazardous stuff. The tools are also well made and commercial grade. Made in Canada means quality. Supports at vacuum warehouse is awesome. We have been dealing with them for 20 years. Very good people.
