The catch
Roborock S8 MaxV Ultra
The navigation tower is fixed, so it needs more headroom than Saros 10. Measure your lowest furniture rail before you choose.
Side by side
Roborock S8 MaxV Ultra vs Saros 10: S8 only lifts its mop, whereas Saros leaves it behind
Quick verdict
If low furniture or leaving the main wet mop at the station is a hard requirement, the Saros 10 is the choice. The S8 MaxV Ultra fits better when you like its dual-roller vacuum head and the current offer looks good. Vibrating mops are on both, but the S8's 20 mm mop lift is not the same as the Saros leaving its mop behind.
Before you buy
Why, and what it costs you
Taking the mop off alters the carpet problem
Saros can vacuum with its main mop off. On the S8 the lifted pad stays attached, which keeps pad clearance relevant.
Where this comes from
Mop lifting on S8 MaxV Ultra is specified at up to 20 mm. At its station, Saros 10 supports automatic main-mop detachment.
The catch
Roborock Saros 10
In the manufacturer's tests, a single vertical step tops out at 1.18 inches. The 1.57-inch climbing claim refers to two-level thresholds.

Differences you will notice
Taking the mop off alters the carpet problem
Saros can vacuum with its main mop off. On the S8 the lifted pad stays attached, which keeps pad clearance relevant.
How we worked this out
Mop lifting on S8 MaxV Ultra is specified at up to 20 mm. At its station, Saros 10 supports automatic main-mop detachment.
Suction does not mean 2.2-times the cleaning
Saros is rated at 2.2 times the S8, yet that ratio is not a measure of debris removal from a rug.
How we worked this out
22,000 / 10,000 = 2.2 for manufacturer-rated pressure. Because of brush design, airflow and test conditions, it cannot be read as a pickup ratio.
Low access is a reason to switch you can measure
Above the Saros's lowered body, a 90 mm furniture opening leaves 10.2 mm. Before buying for that access, confirm the whole route in.
How we worked this out
90 - 79.8 = 10.2 mm, based on the published lowered height of Saros 10. Uneven floors, fabric and navigation behavior are not part of that margin.
Option A

- Automatic detergent dosing and Reactive AI 2.0 obstacle recognition
Option B
Roborock, Saros 10
Saros 10
Its retractable navigation tower lets the vibrating mop reach beneath low furniture. Before vacuuming carpet, it can park its main mop at the dock.
- Best for
- A vibrating mop under low furniture
Facts we checked
- Body height of 79.8 mm once the navigation tower is lowered
- Specified mop pressure of 8N, plus automatic detachment of the vibrating mop
- Threshold ratings of 30 mm for a single step and 40 mm for two levels
Spec by spec
Where they really differ
| Spec | Roborock S8 MaxV Ultra | Roborock Saros 10 | In practice |
|---|---|---|---|
| Main brush arrangement | Dual rollers | DuoDivide split brush | The shape of the brush counts for more than where the model sits in the lineup. |
| Mop motion | Vibrating pad | Vibrating pad | Both scrub in the same broad way. |
| Wet-mop separation | Raises the mop up to 20 mm | Can leave the main mop at the dock | Removal means not relying only on lift clearance. |
| Low-body design | Conventional tower body | Retractable tower, 79.8 mm lowered | Hold furniture sizes up to the exact robot dimensions. |
| Obstacle approach | Camera-assisted Reactive AI 2.0 | Camera-assisted sensing with retractable navigation | Do not trust either one around pet waste or loose cables. |
| Rated suction | 10,000 Pa | 22,000 Pa | The bigger number is no measured pickup ratio. |
Trade-offs
What each pick costs you
With Roborock S8 MaxV Ultra
- The mop lifts and does not detach on its own, so thick rugs may still call for avoidance zones.
With Roborock Saros 10
- You still fill and empty the water tanks yourself. The linked model is the tank version rather than the plumbed-in dock.
Decision guide
How to decide
Treat carpet protection as a physical choice
A lifted pad stays on the robot, and a detached pad stays at the station. That difference tells you more than calling one flagship better across the board. With thick or moisture-sensitive rugs, begin with the cleaning sequence that keeps the wet main mop away.
Don't swap out an S8 that suits you for suction alone
Dual rollers on the S8 and a split brush on the Saros make for different cleaning heads. Pressure ratings do not show which one pulls more embedded hair out of your carpet. A higher number alone is a weak reason to replace an S8 that already fits your rooms and routine.
Put the low body to work where it pays off
The Saros's retracting tower earns its keep when it opens up a space you would otherwise clean by hand. Look at the underside of the bed or sofa, and not only the front edge, because a blocked route farther under can cancel the benefit of fitting through the entrance.
What this page can’t tell you
- Specs from the manufacturer describe the hardware only. They are no substitute for a shared cleaning test and guarantee nothing about performance on every floor.
