Numatic TT4055G

Mains power still suits buildings with sockets and predictable layouts. This mains 40L walk behind scrubber with a 550mm brush suits buildings that prefer plugged power over battery rotation.

The TT4055G suits schools, offices and retail units doing mains powered walk behind scrubbing on hard floors. Fill the 40L solution and recovery tanks, lower the 550mm brush running at 150rpm, and walk steady lanes with recovery keeping floors open behind. The wider brush path covers more per fill than the TT4045G, which trims passes down long corridors. Cable planning around the 550mm lanes keeps the lead behind the operator at all times.

The specification pairs 40L solution and recovery tanks with a 550mm brush working width at 150rpm brush speed. Mains walk behind geometry gives continuous power without battery swaps, trading cable management for unlimited runtime per shift. The 150rpm brush speed holds a steady scrubbing action suited to maintenance passes rather than aggressive restoration.

Rinse both 40L tanks, clean the squeegee and filters, and coil the cable without kinks after every shift. Park with brushes raised and tanks vented so seals dry fully. Keep spare blades, brushes and pads at the charging cupboard even on a mains machine, because consumables still decide whether the wider path performs.

Key points
