The Mercury STORM WVC-20 is a 20-gallon dual-motor wet/dry vacuum on a chromed stainless-steel tank, built for commercial flood cleanup, restoration, and heavy janitorial work. Dual 1.335 HP motors deliver 2.67 HP combined, 225 CFM of airflow, and 78 inches of water lift -- the spec that determines how much water the unit can pull out of a flooded carpet, hard floor, or basement in one pass. Janitorial crews, restoration techs, plumbers, and facility managers reach for this class of vac when a household shop-vac just is not enough machine for the job.
Use cases
- Flood and water-damage cleanup in commercial buildings, basements, and crawl spaces
- Plumbing emergencies: pipe breaks, supply line failures, hot water tank leaks
- Carpet over-wetting recovery after extractor passes
- Janitorial wet/dry cleanup of restrooms, locker rooms, and shop floors
- Auto detailing for shops that need a dedicated shampoo-extractor companion
- Construction and contractor cleanup of drywall dust, sawdust, and slurry
- Industrial spill response in warehouse and manufacturing facilities
Why the chromed steel tank matters
The WVC-20's chromed stainless-steel tank distinguishes it from the plastic-tank WVP-20 sibling at roughly the same spec. Steel tanks survive bumps from rolling restoration carts, drywall scrapes, and impact with door frames in tight basements. They also clean up after a session of pulling oily or chemical-laden water, where the chrome surface releases residue better than a porous polyethylene tank. For contractors who use the vac for restoration or industrial spill work, the steel tank is the right investment over the poly version.
Frequently asked questions
How much water can it actually pick up?
The WVC-20 has a 20-gallon dry capacity and a 15-gallon wet capacity (about 5 gallons of headroom keeps water from being pulled into the motors when the tank is full). A 15-gallon fill on a restoration job is roughly 125 pounds; most operators dump at the 10-gallon mark to keep the unit easier to wheel.
Can I run both motors at once?
Yes. The two switches on the head let you run one motor for lighter work and conserve cord amperage, or both motors for maximum lift on heavy water pulls. Two motors on a 20-amp circuit will draw close to capacity, so plan your outlets accordingly.
What is the warranty?
Mercury Floor Machines covers the motors and parts for one year against manufacturing defects. Routine wear items (filters, hoses, brushes, wheels) and damage from misuse or improper chemicals are excluded.
What hose and tools are included?
The vac ships with a 5-piece tool kit: crevice tool, dust brush, squeegee tool, scalloped bristle floor tool, and a two-piece wand. The standard hose is 1.5-inch by approximately 6 feet; many operators add an extension hose for restoration work in larger spaces.
How does it compare to the WVP-20 poly-tank version?
The WVP-20 has the same motor and airflow specs in a polyethylene tank. The WVP weighs slightly less and costs less; the WVC trades that for impact resistance and easier residue cleanup. Detailers and light janitorial crews often choose the WVP; restoration techs and contractors choose the WVC.
Does it have a built-in pump-out?
The base WVC-20 is gravity-drain. Mercury offers an optional pump-out kit if you need to evacuate water without lifting the tank or tipping the unit. For restoration crews doing repeated flood pulls, the pump-out kit pays for itself within a few jobs.
