DeWalt 6 Gallon Poly Wet/Dry Vac vs Ridgid 3 Gallon NXT Portable Wet/Dry Vac

Quick take: The Ridgid 3 Gallon NXT Portable Wet/Dry Vac costs $31 less.

Which one to buy

Roll it or carry it: these two cheap shop vacs are nearly opposite in shape. The DeWalt 6 Gallon Poly at $75 is a rolling shop vac: a 6-gallon tank on rubberized casters, a washable cartridge filter, a blower port and 80 CFM published alongside its 4 peak HP. The Ridgid 3 Gallon NXT at $79 is a 12.6 lb toolbox-style unit with no wheels, 100 CFM, a built-in RIDGID Sweep dustpan and a Full Lifetime Warranty against DeWalt's 3 years.

Ridgid owners like the Sweep feature for clearing floor debris without bending for a dustpan, the onboard storage for cord, hose and tools, and how easily it stacks away or carries one-handed. They also list its limits: a 3-gallon tank that needs frequent emptying, a 6-foot hose, 48 inches of water lift that suits light spills more than standing water, and a lifetime warranty that only applies once you register it.

DeWalt owners describe respectable everyday suction and wet/dry use from workshop debris to car detailing, while saying it is not the most powerful shop vac and that the poly tank lacks the toughness of DeWalt's steel models. Their main warning is never to run it without the filter in place, and some point to Ridgid's lifetime warranty as an advantage DeWalt doesn't match.

For wet cleanup or a garage floor, the DeWalt's double-size tank and wheels make it the better tool. For a workbench, truck or small shop where you carry the vac to the mess, the Ridgid's warranty and Sweep feature are worth the extra $4.
