Roborock S8 MaxV Ultra: Specs, Features, Pros & Cons
Roborock counts eight jobs in the dock that comes with the S8 MaxV Ultra. It empties the robot, washes the mop pads, doses detergent on its own and dries the pads with air warmer than most rivals use. The robot it serves sits above the Qrevo models, at the top of the maker's mainstream range.
The robot's own defining number is its mop lift. The pads rise 20 mm when the robot rolls onto a rug, about twice what most mopping robots manage, so a rug and the tiles around it can share one scheduled run with nothing fenced off in the app. Around that come LiDAR navigation, obstacle avoidance, maps for several floors, an extending FlexiArm for edges and dirt detection that orders a second pass. A rubber brush does the vacuuming, and the pads come off for a hand wash.
The compromises lie in the numbers the lift does not touch. Suction trails most rivals by a wide margin, so a deep carpet gets a lighter clean than the lift might suggest. The wash water is cooler than most rivals use, and the threshold clearance is lower than on many rivals, so a raised door saddle can end a run. Roborock gives no runtime figure for the battery. The body is tall, which leaves low furniture out.
The whole design aims at one robot and one schedule for a home that mixes surfaces room by room. Rugs laid over hard floor, flush doorways and furniture tall enough to pass under make the floor plan it was built for, and topping up the detergent now and then is the only chore it leaves behind.

How this VS Score was computed
Score 54: each known spec is measured against the median of all robot vacuums (58 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 48% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
The S8 MaxV Ultra is the top of Roborock's mainstream range, and the specification that most separates it from the Qrevo models below it is how high the mop lifts.
That figure decides whether a home with both hard floor and carpet can be cleaned in a single run. At full lift the pads clear medium-pile carpet entirely, so the machine mops the tiles and vacuums the rug without you cordoning anything off. The Qrevo models manage 7 to 10 mm, which handles a thin rug and not much more.
Suction is 10,000 Pa through a DuoRoller rubber brush, the dock washes the pads at 60 degrees C and dispenses detergent automatically, and dirt detection triggers a second mopping pass over an area that comes up dirty. It stores four floor maps, so a multistory house works without re-teaching it.
Navigation is LiDAR with obstacle avoidance, and the 5,200 mAh battery supports recharge-and-resume, though Roborock states no runtime figure. The bin holds 270 ml and the tank 100 ml. The pads are removable for hand washing, and the filter is washable.
Two limits. It is 103 mm tall, so low furniture is out. Measure first. And Roborock states no threshold figure, so assume a raised door saddle will still stop it.
Buy it if you have carpet and hard floor in the same rooms and want one run to handle both. Buy a Qrevo if your floors are uniform, where the extra lift buys nothing.

The bottom line
The Roborock S8 MaxV Ultra earns a VS Score of 54, above the median of the 58 robot vacuums it is measured against (a score of 50 is level with that median).
- Who it’s for
- Rugs and hard floor in the same rooms, in a home that wants one scheduled run to mop and vacuum without zones drawn in the app.
- Who should look elsewhere
- Uniform hard floors get nothing from the lift, and low furniture or raised saddles point to another machine.
- The trade-off that matters
- Suction is modest for the top of Roborock's mainstream range, so the mop lift is what you are paying for and deep pile gets a lighter clean.
- The main alternative
- Roborock Qrevo: the same kind of self-servicing dock for much less, if every floor is hard
