HOW TO USE IT

GENERAL QUESTIONS

What types of floors can the RT15 clean?

SUNMAX Floor Scrubber Machines are best for cleaning a wide range of floor surfaces, including:

  1. Hard Floors such as tile, ceramic, porcelain, marble, granite, concrete, and vinyl;
  2. Sealed Wood Floors: we recommend using SUNMAX soft brushes or pads that are gentle on wood surfaces;
  3. Linoleum floors which are often found in commercial spaces;
  4. Laminate: we recommend using soft brushes or pads to avoid scratching the surface;
  5. Epoxy-coated floors which are commonly found in industrial settings;
  6. Rubber floors which are often found in gyms and sports facilities;
  7. Terrazzo floors made from a mix of marble chips and concrete;
  8. Concrete floors in warehouses, factories, and distribution centers;
  9. Grouted Floors.

⚠️ Attention: Add cleaning chemicals without oxidizing agents, chlorine or bromine, formaldehyde, or mineral fluxes, such as acid or alkaline cleaners.

Nice floor machine.

This is a very lightweight scrubbing machine very easy to handle small water tank but good for smaller areas.

Great Customer Service

This is a quality scrubber at a reasonable price. I've ordered several for our organization. I had a faulty vacuum pump on one of our scrubbers, so I called Sunmax, and they were fantastic to work with. They sent out a new pump free of charge and it has been working great!
