- ✓Mop lifts 10.5mm, one of the highest in the market
- ✗Suction power at 7000Pa is mid-range for the price
- ✗Dock is bulky and the water tanks need refilling every few cleans

- ✓Anti-tangle brushes genuinely resist pet-hair wrap
- ✓Dual spinning mops scrub better than flat-pad budget rivals
- ✓180-minute runtime covers large homes in one charge

- ✗Only a 1-year warranty
