Walmart offers the Vacmaster 2.5-Gallon Portable Wet/Dry Vacuum, model no. VP205, for $28.83. Choose in-store pickup to dodge the $4.97 shipping fee. (Home Depot charges the same with pickup; Amazon charges the same shipped for Prime members.) That's the lowest price we could find by $11. It features a 2HP motor, 4-foot x 1.25" suction hose, and 8-foot power cord.
