The NaceCare CTB 370NX: A Cordless Carpet Spotter That Sprays, Scrubs and Extracts
A coffee lands on the carpeted stairs ten minutes before the board meeting. Dragging the big extractor up there means a cord across the landing and an outlet you can't find. The NaceCare CTB 370NX battery carpet spotter runs on a 36-volt NX300 lithium battery for up to 40 minutes, weighs 21 lbs, and sprays, scrubs and extracts the stain where it is.
A 26-watt pump at 33 psi puts down cleaning solution at 0.3 gallons per minute, and a 400-watt motor with 105 cfm pulls it back out of the carpet. Swap tools and the same machine cleans upholstery, restroom corners and the tile around fixtures that a floor scrubber can't reach.
The Owner's Insights on the CTB 370NX
What sells me on the CTB 370NX is how fast it goes from closet to stain. No hose to the sink, no cord, no warming up: fill the inner tank with cold water and solution, click in the battery, and you're extracting. When you're done, the wand docks on the back of the machine.
It's a spotter, not a carpet extractor for whole rooms. The clean water tank holds about 1.6 gallons, and at 0.3 gallons a minute that's roughly 5 minutes of trigger time per fill. NaceCare also says to use cold water only, up to 68°F. If you're cleaning hallways wall to wall, look at a box or walk-behind extractor. For stairs, upholstery, spills and the corners everything else misses, it's one of the handiest machines we sell.
Why You'll Love the CTB 370NX Battery Spot Extractor
Cordless spray extraction. Clean stairs, landings and seating with no cord across the floor.
Carpet, upholstery and hard floors. Pick the kit that matches the surfaces you clean most.
33 psi pump, 105 cfm vacuum. Enough to flush a stain out and leave the fibers damp, not soaked.
64 dB(A). Just above normal conversation at about 60 dB, so you can spot clean an open lobby.
2,000-hour motor, 5-year motor warranty. Per NaceCare's spec sheet.
NX300 battery, 2,500 cycles. NaceCare puts that at about 10 years of cleaning 5 days a week, and it charges to 80% in an hour.
Which Kit Should You Pick?
Every CTB 370NX comes with one NX300 battery and a charger. Tap a picture to see it up close.
A42 kit: 10-foot hose and 4-inch hand tool. The classic spotter setup at $1,549. Best for upholstery, stairs, car seats and small carpet stains you clean on your knees.
A40B kit: extraction kit, hand tool and hard floor brush. Adds $100 over the A42. The pick when restroom tile, grout lines and sealed floors are part of the job.
CTX 170 X-tract wand. Adds $200 over the A42. A stand-up wand that switches between a scrub brush and an extraction head, so you clean carpet and hard floors without kneeling. It docks on the back of the machine.
One battery or two? A second NX300 in the box adds $575, about 80 minutes in all. One battery handles a day of spot calls; take two if the machine runs a scheduled stair or seating route.

Battery Carpet Spotter or Portable Carpet Extractor?
A spotter wins on small, scattered jobs: one stain here, a stair run there, a chair in the lobby. Because there's no cord, the CTB 370NX is working while you'd still be unrolling an extension cord, and it rides between floors easily at 21 lbs.
A portable box extractor wins on whole rooms. Bigger tanks, hotter water and a longer reach mean fewer refills. If you only need to pick up water, the NaceCare WVB 370NX cordless wet/dry vacuum uses the same body and battery and costs $50 less. Compare more machines in our carpet spotters and portable carpet extractors collections.
Happy to work near an outlet? The NaceCare GVE 370 George is the corded spotter from the same Numatic 370 range, for $700 less. The corded NaceCare TP 4X steps up to 4-gallon tanks and a 2 hp vacuum, for about $440 less.
Why You Should Consider a NaceCare Carpet Spotter
NaceCare is Numatic's North American distributor, and Numatic builds the CTB 370NX in England on the same NX300 battery platform that runs NaceCare's cordless vacuums and scrubbers, so one spare battery covers several machines. We're an authorized NaceCare retailer, so the full NaceCare warranty comes with every machine. Found a lower price? Call or message us and we'll beat it.
