Shop-Vac 5 Gallon 4.5 Peak HP Wet/Dry Vacuum, Stainless Steel Tank, 5920588 Review (2026)

Overview

Model 5920588 is Shop-Vac's 5 gallon wet and dry vacuum built around a stainless steel tank instead of the plastic tank used on the brand's similarly specced 5971536 model. It carries the same 4.5 peak HP motor rating, runs on a standard 120 volt household outlet, and draws 9.9 amps, so it fits any typical garage or workshop circuit without special wiring. The unit ships with a 7 foot by 1.25 inch hose, three extension wands, a 10 inch wet and dry nozzle, a crevice tool, a gulper nozzle, and a tool holder for keeping accessories organized on the tank between uses.

Stainless steel tank

The main difference from Shop-Vac's plastic-tank counterpart is the tank material, described by Shop-Vac as a durable, easy to clean stainless steel tank that is more resistant to dents, scuffs, and long-term wear than a plastic tank exposed to years of garage use. Stainless steel also tends to hold up better if the vacuum gets knocked around while being moved in and out of storage. The tradeoff is added weight, since a metal tank is heavier than the equivalent plastic one, which matters if the vacuum needs to be carried up stairs or into a vehicle regularly for use away from the garage.

Suction and performance

Shop-Vac lists this 4.5 peak HP class of motor at up to 70 CFM of airflow and 58 inches of sealed pressure, with a rear blower port that lets the same hose blow debris out of tight corners instead of only vacuuming it up. The 6 foot power cord and 1.25 inch hose diameter match the rest of Shop-Vac's standard lineup, keeping clog risk low for typical shop debris like sawdust and shop floor spills. As with all shop vacuums, peak horsepower is a lab-measured figure rather than continuous real-world output, so real airflow will vary somewhat depending on the hose and attachment used.

Warranty and durability

Shop-Vac backs this model with what the company lists as a limited lifetime home use warranty for the original purchaser, a longer coverage period than many wet and dry vacuums in this price range typically offer. Combined with the stainless tank, that warranty signals the model is positioned as a longer-term garage fixture rather than a budget disposable vacuum meant to be replaced after a few seasons. Buyers should register the purchase and keep the receipt, since lifetime warranties on home use products commonly exclude commercial or rental use, and proof of purchase is usually required to process any warranty claim down the road.

Who it's for

This model suits a garage owner who wants the extra durability of a metal tank and is willing to carry a bit more weight in exchange, particularly if the vacuum will be moved around a workshop or stored somewhere it might get knocked or scraped. It is a reasonable step up from the plastic-tank 5971536 for anyone planning to keep the vacuum for many years of regular garage use. Buyers who prioritize a lighter unit over tank durability, or who want the built-in blower highlighted more prominently, may prefer the plastic-tank sibling instead, since both share the same 4.5 peak HP motor, hose length, and accessory set.
