Price does not count, so a discount never lifts a model. Only robots a lab has tested are ranked.
The highest score today is 8.0.
Beside it, a model with the same kind of station that scores about the same for at least 25% less, and one that scores clearly higher for at most 20% more, where we find them on sale today.
Green is the best of these 3, also when they share the lead.

The Roborock Saros 20 is a flagship with an embedded lidar and no turret, keeping it under eight centimetres tall, a lifting chassis that carries the robot over thresholds of more than four centimetres and adapts to thick carpet, two spinning mop pads that detach automatically, and a station that washes in boiling-hot water, dries with hot air and doses detergent. TechRadar names it the best robot for carpet, Tom's Guide the best for pet hair, and Vacuum Wars ranks it 11th of 20.
All three testers see the same strength: embedded pet hair and sand in carpet. Tom's Guide measured the effect of the 36,000 Pa of suction, the highest in their guide, and saw the twin anti-tangle brush stay clean even after heavy runs; Vacuum Wars lifted 89 percent of the sand out of carpet and 88 percent of the pressed-in pet hair, with a perfect score in the long-hair test. Obstacle recognition dodged toys and bowls reliably, and the low build takes it under furniture a turret cannot. The pads press with adaptive force and use less water than average, which limits streaks.
The criticism targets mopping and price: Tom's Guide saw patches missed and visible streaks in the lab, TechRadar still finds sticky spills a job for a cloth, and both call it more machine than many homes need, at a price to match. TechRadar also saw the odd strange behaviour on certain tasks. For homes with plenty of carpet, thick rugs, high thresholds and shedding pets it is one of the best choices; if mopping is the priority, look at a roller-mop model.

Yes. The station empties the robot’s dust bin after every run. The 2.7 l dust bag in the station lasts up to 65 days, the maker says.
Yes. The station washes the mop itself, with water at 100 °C. It then dries the mop with warm air.
It works with Alexa, Google Assistant and Siri. It also supports Matter, so it fits into another brand’s app. Home Assistant has an official integration for this model.
Thresholds up to 45 mm, the maker says. With its climbing system it also takes two steps close together, up to 88 mm in all. Measure your own thresholds: the ones to a bathroom or balcony are often higher.
The robot is 8 cm tall, so it fits under furniture with at least 8 cm of clearance. It has no turret on top.
Yes, the maker says. The brush guides hair to the side instead of winding it round the roller.
