Is this the right machine for you?
Best for:
- Grout, textured tile, quarry tile and uneven floors: roller brushes reach low spots
- Floors with small debris: the brushes sweep it into a tray while they scrub, so you often skip the sweeping step
- Schools, healthcare, retail, food service and offices: 60 dB(A) in eco mode (TASKI figure)
Not a good fit for:
- Round pads and pad polishing: this machine uses roller brushes and pad rollers
- Large debris such as cans, bottles or pallet scraps: sweep first
- Carpet
