NaceCare TBL 2228/150T 28" Walk-Behind Scrubber – 3 LFP Batteries, 5 hr Runtime

28" Traction Drive Walk-Behind Scrubber with 5-Hour LFP Runtime for High-Demand Shift Cleaning

The NaceCare TBL 2228/150T is a traction-drive walk-behind floor scrubber engineered for high-volume commercial and industrial facilities that need full-shift runtime without battery swaps. Three NX1K lithium phosphate batteries provide up to 5 hours of continuous operation, a 7-hour full recharge, and over 4,000 cycle life — all in a simplified mechanical design that eliminates actuator motors and complex electronics. The 28" dual-brush cleaning path delivers 110 lbs of adjustable brush pressure at 150 rpm, cleaning 31,000 sq ft per hour on concrete, VCT, epoxy, and terrazzo surfaces.

TBL 2228/150T Drivetrain, Brush Deck, and Tank Specifications

• 28" dual-brush cleaning path with two 14" brushes at 150 rpm — overlapping brush coverage prevents centerline residue on wide-aisle institutional floors
• 110 lbs adjustable brush pressure — maximum in the TBL walk-behind lineup; suitable for removing buildup on rough concrete and quarry tile
• Traction drive at up to 4.3 MPH transport speed — self-propelled across large floor areas; operator controls speed via ergonomic handlebar
• Three NX1K lithium phosphate batteries — 5-hour runtime covers a full cleaning shift; zero equalization or water maintenance required
• 7-hour full charge time with on-board charger — charge overnight between shifts using a standard 120V outlet; no external charger or battery removal needed
• 4,000+ charge cycle rating — LFP chemistry does not degrade under regular partial-charge cycles, unlike lead-acid chemistry
• 23-gallon solution and 23-gallon recovery tanks — extended capacity reduces refill interruptions on large open-floor areas
• No actuator motors or complex control boards — toggle switches for vacuum and water control; fewer electronic failure points reduce service calls
• Tool-free squeegee blade change — blade replacement in under 5 minutes; easy-fill hose access on solution tank lid
• Nu-Assist App integration — QR-code access to operator training, maintenance schedules, and diagnostics from any smartphone

Industries and Floor Types Where the TBL 2228/150T Performs

The TBL 2228/150T is built for large single-floor facilities where a walk-behind scrubber is preferred over a ride-on for maneuverability around racking and equipment. Warehouse and distribution centers use it on sealed concrete floors during off-peak hours, relying on the 5-hour runtime to complete full building passes without stopping to recharge. Schools and university facilities deploy it for evening cleaning of gymnasium floors, cafeterias, and corridor VCT. Healthcare facility managers choose the TBL 2228/150T for patient wing corridors and clinical ancillary spaces where the simplified electronics and no-maintenance batteries reduce total cost of ownership versus comparable lead-acid walk-behind machines. Hospitality and retail environments benefit from its 4.3 MPH transport speed for fast repositioning between zones.

Simplified Mechanics, LFP Safety, and What Ships in Box

NaceCare's decision to remove actuator motors from the brush deck mechanism means the TBL 2228/150T has fewer solenoids, relays, and control boards than competing units — each eliminated component is one fewer failure point for in-house maintenance teams. The NX1K lithium phosphate chemistry is thermally stable: LFP cells do not exhibit the thermal runaway risk associated with NMC or NCA lithium chemistries, making them safe to charge in occupied building mechanical rooms. The machine ships with three NX1K batteries installed, one set of scrub brushes, the squeegee assembly, on-board charger, and operator documentation.
