A supply line breaks overnight in a basement storage room with no floor drain. With an ordinary wet vac you fill 20 gallons, stop, roll it to a sink, lift, pour and start again, for hours. The NaceCare WV 1800P pumper wet vac doesn't stop: a float-activated sump pump inside the 20-gallon tank pushes water out through a 33-foot discharge hose while you keep vacuuming.
The 500-watt centrifugal pump moves up to 60 gallons per minute on the flat and 7 gallons per minute up 22 feet, enough to send water up a basement stairway to a sink or out a window. Choose a single 1,200-watt motor (WV 1800P) with 100 inches of water lift, or twin motors (WVD 1800P) with 180 cfm of airflow.
A pumper is an expensive wet vac, so I'd only buy one where water has nowhere to go: basements without drains, elevator pits, parking garage stairwells, flooded mechanical rooms, and restoration crews who walk into a different building on every call. There it earns its price on the first big leak.
Be realistic about what it is. It weighs 85 to 90 lbs and ships with a wand kit, not a squeegee, so it's a pickup machine, not a floor dryer. If your building has floor drains, the WV 1800DH does the same pickup for much less. Single or twin motor? The single motor has more water lift, which helps through a long hose. The twin motors move nearly twice the air, which pulls shallow water across a floor tool faster.
Continuous pump out. The float switches the pump on as the tank fills, so you never stop to dump.
60 gpm on the flat, 7 gpm at 22 feet. Send water to a sink, a drain or outside, even one floor up.
33-foot discharge hose included. Run it to the nearest drain without moving the machine.
20-gallon structural foam tank. Rustproof, and covered by NaceCare for 10 years.
A pump built for dirty water. High-impact plastic housing for heat and chemical resistance, a stainless steel shaft, a triple seal and thermal overload protection.
Rotating ball float shutoff and a 42-foot cord. The motor stays dry, and the outlet can stay well away from the water.
WV 1800P, $3,349. One 1,200 W (1.6 HP) motor, 100 inches of water lift, 95 cfm, 64 dB(A), 85 lbs. The pick for deep standing water and long hose runs.
WVD 1800P, $300 more. Two 800 W motors, 90 inches of water lift, 180 cfm, 67 dB(A), 90 lbs. The pick for wide floors with a shallow layer of water, where airflow matters more than lift.
Both have the same tank, the same 500 W pump, the same 33-foot discharge hose and the same BS7 wand kit. Not sure which fits your calls? Tell us what you pump out and how far the water has to go, or call (855) 601-5678.
1. Make it safe first. Shut off power to anything electrical sitting in the water, and plug the pumper into a GFCI-protected outlet above the water line.
2. Lay out the discharge hose. Run the 33-foot hose to a sink, floor drain or outside, keep it free of kinks and tie the end down so it can't whip around.
3. Work toward the machine. Start at the far edge and pull water toward you with the wet floor tool. When the tank level reaches the float, the pump starts on its own and keeps pace.
4. Finish clean. We'd finish by picking up a bucket of clean water so the pump and hose flush out, then empty the tank and leave the head off to dry.
One thing a pumper won't do is dry the floor. After the standing water is gone, you'll still want air movers or a squeegee pass on hard floors.
Have floor drains? The NaceCare WV 1800DH is the same 20-gallon machine with a dump hose instead of a pump, for $1,950 less. Honestly, if every room you clean has a drain, that's the smarter buy.
Comparing flood machines? The EDIC Floodbuster flood pump extractor is another dedicated flood machine with continuous pump out, rated at 50 gpm, for $783 more than the WV 1800P. For everyday spills, see our full range of commercial wet dry vacuums.
NaceCare is Numatic's North American distributor, and Numatic has built structural foam wet vacs in England for decades, so floats, hoses and pump parts stay easy to get. The 1800P pumpers are covered by NaceCare's 2025 US warranty for wet dry vacuums: 10 years on the structural foam body, and 2 years on the motors, switches, electrical parts and labor. We're an authorized NaceCare retailer, so that warranty comes with every machine. Found a lower price? Call or message us and we'll beat it.
