NaceCare CV 570 CombiVac: The Commercial Wet Dry Vacuum That Never Needs a Filter Swap
A cup of coffee hits the lobby floor, someone tracks slush through the entrance, and the mat by the door is full of grit. With most wet dry vacs that's three jobs and a filter change in the middle. The NaceCare CV 570 CombiVac handles all of it in one pass, because its combination filter picks up wet and dry without changing filters or kits.
It's built by Numatic in England and sold in North America by NaceCare as a 120-volt commercial machine. The 6-gallon structural foam tank won't dent or rust, the 1,200-watt bypass motor (1.6 HP) delivers 95 cfm and 100 inches of water lift, and a 42-foot cord lets you cover a lobby or a hallway without hunting for outlets.
A ball float shuts off the airflow before water can reach the motor, dry soil is filtered to 0.5 micron at 98.6% efficiency, and it runs at 64 dB(A), so you can clean up while the building is open.
The Owner's Insights on the CV 570
What sells me on this machine is the filter. On a typical wet dry vac you pull the dry filter before you pick up water, then wait for it to dry before you vacuum dust again. Crews skip that step, the filter gets soaked, and the motor pays for it. The CV 570 takes that decision away from them.
Be honest about what it is, though. It's a compact 6-gallon machine for spills, entryways, restrooms, job site cleanup and daily dust, not a flood pump. There's no drain hose, you empty it by the carrying handles, and at 34 lbs it's heavier than a plastic shop vac because the tank is structural foam. If you're pulling water out of a flooded basement every week, step up to a 15 or 20-gallon machine like the ones linked below.
Why You'll Love the CV 570 Commercial Wet Dry Vac
Wet and dry with the same filter. The dual filtration system works for both at once, so there's no swapping, no soggy dry filter and no downtime between jobs.
Structural foam tank. Tough, light for its strength and nothing to rust, even after years of dirty water.
1,200 W bypass motor, 95 cfm, 100" water lift. A bypass motor keeps the cooling air separate from the dirty air, which is what you want in a machine that picks up water.
Ball float wet shutoff. The ball rotates as it works, so it stays clean and keeps closing reliably when the tank is full.
0.5 micron filtration at 98.6%. Dry dust stays in the tank instead of blowing back into the room.
42-foot power cord. Nearly three times the cord of a typical 15-foot shop vac.
64 dB(A). Quiet enough for daytime cleanup in lobbies, schools and offices.
Carrying handles and casters. It rolls on the floor and lifts with two hands to dump.
Which Tool Kit Should You Pick?
Both kits are 1.5-inch wet and dry kits with a 10-foot hose, a 3-piece stainless steel wand and NaceCare's 16-inch wet floor tool with squeegee blades. They cost the same. The difference is the dry floor tool.
BB8 kit (906566). Adds a dry brush floor tool. It's the standard kit and the one to pick for hard floors: tile, VCT, sealed concrete, entryways and restrooms.
BOW kit (K-8026560). Swaps the brush for a dry combination floor tool. Pick it if the machine also has to vacuum dry debris off carpet and mats.

How the CV 570 Compares to Other Commercial Wet Dry Vacuums
Want something lighter? The Clarke Maxxi II 35 wet/dry vacuum holds 9 gallons, weighs 25 lbs and has a 50 ft cord, for $427 less. It has 72 inches of waterlift to the CV 570's 100 and runs louder, at 81 dB(A).
Want the same water lift in a smaller machine? The NaceCare CVC 370 Charles holds 4 gallons, weighs 19 lbs and has the same 100 inches of water lift and 42 ft cord, for $370 less. The catch: you swap a bag and filter between dry and wet jobs.
Want a bigger NaceCare tank? The NaceCare WV 900 holds 12 gallons in a tank that drains through a dump tube or tips forward to pour, starting at $1,059. With the same BB8 kit it costs $150 more than the CV 570.
Honestly, if your messes are small and frequent, the CV 570 is the better daily machine. If they're big and wet, buy the bigger tank. Browse them all in our commercial wet dry vacuums collection.
Why You Should Consider a NaceCare Vacuum
NaceCare is Numatic's North American distributor, and Numatic has been building commercial vacuums in England for decades, so parts and service aren't going anywhere. The CV 570 is covered by NaceCare's 2025 US warranty for wet dry vacuums: 10 years on the structural foam body and 2 years on the motor, 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.
Do I need to change filters between wet and dry pickup?
No. That's the point of the CV 570 CombiVac. Its combination filter system works for wet and dry pickup at the same time, so you can vacuum dust and then pick up a spill without stopping to swap or dry a filter.
What's the difference between the BB8 and BOW kits?
Both include a 10-foot hose, a 3-piece stainless steel wand and a 16-inch wet floor tool with squeegee blades. The BB8 adds a dry brush floor tool, best for hard floors. The BOW adds a dry combination floor tool, the better pick if you also vacuum carpet and mats. Same price either way.
How do I empty it, and what happens when the tank is full?
The tank holds 6 gallons. When it fills with water, the ball float shuts off the airflow so water can't reach the motor. The CV 570 has no drain hose; you lift it by its carrying handles and dump it.
Can it pick up fine dust?
Yes, dry soil is filtered to 0.5 micron at 98.6% efficiency. It isn't a HEPA or hazardous dust vacuum, so don't use it for lead, silica or mold remediation.
How loud is it?
64 dB(A), quiet enough to clean entryways, restrooms and lobbies while the building is open.
Who makes the CV 570?
Numatic International in England builds it, and NaceCare distributes it in North America as a 120-volt machine with NaceCare's US warranty.
What warranty does the CV 570 have?
Under NaceCare's 2025 US warranty chart for wet dry vacuums: 10 years on the structural foam body, and 2 years on the motor, switches, electrical parts and labor.
