Abstract
An improved shop vacuum with wet/dry capability uses a vacuum tube that terminates in a space between the canister and the vacuum compartment such that the fluid and content exiting the vacuum tube is not directly opposed the negative pressure source. This allows the fluid to drain into the canister in a more controlled and less volatile condition, reducing splashing and entrainment of the fluid. Moreover, a second exit for the vacuum has been added to the canister to improve the efficiency of the vacuum and the overall performance of the device.
