Abstract
Portable vacuum systems are provided. In one embodiment, a portable vacuum system includes a tank, an engine, and a transportation system. The engine is configured to generate a vacuum within the tank. The transportation system illustratively has one or more wheels and is configured to tilt the tank about an axis that is between a front and a back of the tank. In other embodiments, a portable vacuum system may also include a swivel elbow that connects the tank to a vacuum wand, a ledge that supports the engine, a back door that forms a seal with the tank along a curved lip, and a filter that is accessible through a threaded cover on the tank. Additionally, one or more of the components of a system may be made utilizing rotational molding.
