Score 7.4 out of 10
Test-site results, 60% of the score: 7.0, measured by Just A Dad Approved and Vacuum Wars.
Owners’ ratings, 25%: none yet at the shops that deliver to the Netherlands, so this part is left out and the others count for more.
Features, 15%: 8.9, 82 of the 92 points for the facts the maker states.
Price does not count, so a discount never lifts a model. Only robots a test site has tested are ranked.
The highest score today is 8.0.
Beside it, two models on sale today that come closest to it on score and price, with the same kind of station where we have them.
Green is the best of these 3, also when they share the lead.

The Dreame L40 Ultra is an all-in-one robot with two spinning mop pads that extend and swing, an extending side brush and camera-based obstacle recognition. The station empties the bin into a 3.2-litre bag, washes the pads in 65-degree water, dries them with hot air, doses cleaning solution and can be plumbed in; the pads stay behind in the station when the robot only vacuums. TechRadar names it the best robot for pet hair; Vacuum Wars calls it better than the pricier X40.
TechRadar tested it in a home full of pets and saw it pull more hair out of carpet than any other robot the reviewer had tried, without clogging the emptying mechanism; it also did well on hard floors and mopping muddy paw prints. Vacuum Wars measured the highest battery efficiency it had seen, roughly double the average, with a quoted run time of 194 minutes, and a dried-stain mopping score above average and above the X40. On carpet it lifted embedded sand at an above-average rate.
Both testers' criticism concerns the station: it is big and the styling is not for everyone. Beyond that, the robot is on the tall side at just over ten centimetres, thresholds stop at a little over two centimetres and the quoted 11,000 Pa of suction is modest next to newer models. Compare its price with the L40 Ultra AE and the newer L50 models too.
Each point sums up, in our words, the review of the test it names, and its link leads to that review. We do not summarise RTINGS or Wirecutter: their lists are linked above.
