## Our score

- Score 7.8 out of 10
- Lab tests, 60% of the score: no lab has tested it.
- Owners’ ratings, 25%: none yet at the stores that ship to the United States, so this part is left out and the others count for more.
- Features, 15%: 7.8, 62 of the 80 points for the facts the maker states.
- Price does not count, so a discount never lifts a model. Only robots a lab has tested are ranked.
