Pros
- Roller mop is washed in 140°F water and heat-dried, so it stays clean and odour-free
- Bagless cyclonic dock holds up to 100 days of debris with no bags to buy
- Camera spots stains and obstacles so it can rescrub messes and avoid clutter
- Covered about 850 sq ft per charge in Vacuum Wars’ test
Cons
- Lifted only 76% of sand worked into carpet in Vacuum Wars’ test
- Picked up 80.5% of pet hair on carpet, behind similarly priced rivals
- Stands 4.3 in tall, too high for many sofas and beds
- Dyson publishes no threshold-climbing figure
