NaceCare CTB 370NX Battery Spotter – 400W, 33 PSI, 105 CFM, 40 Min, 21 lbs

NaceCare CTB 370NX: Cordless Spot Extractor for Carpet, Upholstery, and Hard Floors

The CTB 370NX is a battery-powered spotter that sprays, scrubs, and extracts — three functions in one 21 lb cordless unit. A 400W motor rated for 2,000-hour service life drives both the 105 CFM vacuum and the 33 PSI spray pump at 0.30 GPM, while the NX300 36V lithium battery delivers 40 minutes of run time. Dual 2-gallon tanks keep clean solution and recovery water separated for hygienic operation, and at 64 dB(A) the unit runs in occupied buildings without triggering noise restrictions. The A40B kit includes a full extraction hand tool and hard floor brush for immediate multi-surface use.

Spray-Scrub-Extract in One Cordless Unit

• 400W motor with 2,000-hour rated life — built for high-frequency use in commercial facilities without early rebuild
• 33 PSI pump at 0.30 GPM — injects solution at controlled pressure for carpet, upholstery, and hard floor spotting without over-wetting
• 105 CFM / 60" water lift — extracts moisture quickly to minimize dry time after spot treatment
• Dual 2-gallon tanks — separate clean and dirty water prevent cross-contamination between spotting jobs
• NX300 36V battery — 2,500 charge cycles rated; 80% charge in 1 hour supports mid-shift recharging

Restaurants, Gyms, and Multi-Surface Spotting

The CTB 370NX is deployed in environments where spills are frequent, surfaces are mixed, and cord routing is impractical — restaurant dining rooms with booth upholstery and carpet aisles, gym facilities with rubber flooring and textile wall panels, supermarket tile floors with matted entranceways. The 21 lb weight and 40-minute battery support multiple spotting runs between charges, and the A40B kit's hard floor brush switches the unit to tile and vinyl spot-scrubbing without carrying a second machine. The 2,000-hour motor life translates to roughly four years at daily use in a high-frequency spotting program before a motor service is indicated.
