Why we recommend it

  • Available in a REV Orbital variant (REV 51) for deep-clean performance — 2,250 rpm oscillation reaches into grout lines and floor texture that disc scrubbers skim over. Ideal for tiled washrooms, changing rooms and pool surrounds where hygiene and deep cleaning both matter.
  • Run time of up to 3 hours on a 3-hour charge — clean a full shift, plug in over a break, and the machine's ready for the next one. No second battery to buy, no scheduling around the charger.
  • 7" touchscreen with on-board tutorials and step-by-step maintenance guides — first-time operators are productive in minutes, not weeks. Built for high-turnover cleaning teams.
  • Silent Mode across the family runs as low as 56 ±3 dB(A) — quiet enough for daytime cleaning in public buildings, schools, hospitals and hotels where disruption isn't an option.
