Numatic TTB1840NX

Mid size hard floors stay cleaner without a trailing cable. This cordless compact scrubber dryer lays the same 400mm path as the mains TT1840G, so teams keep a familiar lane width while working away from sockets.

The TTB1840NX suits offices, schools, surgeries and retail floors where cables block fire exits or trip the public. Fill, lower the 400mm brush head, and walk steady lanes with the vacuum recovering as you go. One NX300 battery gives 60 minutes, and fitting a second pack stretches the shift to 2 hours without returning to base. The 52kg frame stays planted on the pass yet rolls between areas on its wheels.

The 36V 300Wh NX300 platform drives a 400W brush motor with a 300W vacuum motor behind a 400mm brush width. Charging runs about 2 hours per pack, so rotation planning decides continuous output. Cordless walk behind geometry means the operator guides rather than carries, with weight doing the scrubbing work.

Rinse the tanks, clean the squeegee blades and park on charge with batteries seated correctly. A second battery pack is the difference between one hour and a full morning. Check brush wear weekly, because a worn 400mm brush leaves edge lines that the next pass has to correct.
