NaceCare TT 516 903921 Compact Scrubber – 16", 400W, 65 ft Cord

NaceCare TT 516 903921 – 16-Inch Corded Compact Pad Assist Floor Scrubber, 55 lbs

The NaceCare TT 516 (part number 903921) is a 16-inch corded pad-assist walk-behind scrubber weighing 55 lbs with a 400W brush motor, 400W vacuum motor, 55 lb brush pressure, 40 RPM brush speed, 5-gallon solution and recovery tanks, and a 65-foot power cord. At 67 dB(A) and 17,600 square feet per hour, this machine fills the gap between mop-and-bucket cleaning and larger scrubbers in restrooms, break rooms, small classrooms, and narrow aisles where a 17"+ scrubber is too wide to maneuver.

TT 516 903921 Motor Specs, Brush Pressure, and Cord Length

• 16" cleaning path / 17,600 sq ft/hr: fits through standard doorways and into restroom stalls, classroom aisles, and narrow service areas inaccessible to wider scrubbers.
• 400W brush motor / 55 lb brush pressure at 40 RPM: sufficient downforce for daily scrubbing on commercial hard floors; 40 RPM single-disc pad drive is appropriate for pad-assist scrubbing rather than high-speed burnishing.
• 400W vacuum motor / pivoting squeegee: dedicated vacuum motor maintains independent suction regardless of brush load; pivoting rear squeegee maintains blade contact during turns.
• 5-gal solution / 5-gal recovery tanks: appropriately sized for the 16" path — larger tanks would add unnecessary weight to a 55 lb machine that operators frequently reposition.
• 65-foot power cord: covers most room-size areas without repositioning to a new outlet; significantly longer than the 25–35 ft cords on comparable compact scrubbers.
• 55 lb weight — fits in a car trunk: can be transported in a standard vehicle without specialized equipment, appropriate for mobile cleaning contractors visiting multiple small sites.

Where the TT 516 Replaces Mop-and-Bucket in Tight Commercial Spaces

Mop-and-bucket cleaning on commercial hard floors requires multiple passes and leaves floors wet for extended drying periods. The TT 516's 400W vacuum motor recovers solution immediately after scrubbing, leaving floors dry and walk-safe within minutes rather than the 15–30 minutes typical of mopped floors. In school restrooms, the 16" width clears individual stall areas with one or two passes. In healthcare environments, mechanical scrubbing with solution recovery is a hygiene improvement over mops that recirculate contaminated water across multiple surfaces. The 67 dB(A) noise level allows use during occupied school hours without requiring the area to be cleared.

TT 516 Maintenance and Transport

The 5-gallon tanks drain through a floor drain port without lifting the machine. The pivoting squeegee blade is tool-free for replacement. At 55 lbs, the machine lifts into a car or van without specialized loading equipment. The 65-foot cord stores on the machine frame for transport. Pad replacement is the primary consumable — 16" scrubbing pads are widely available in scrubbing, cleaning, and stripping grades.
