Saros 10 vs Saros 20

Which is better, Roborock Saros 10 or Roborock Saros 20?

Start with the Saros 10 for everyday mixed-floor cleaning; consider the Saros 20 if its extra climbing ability solves a problem in your home.

Updated

The short version

Saros 10Our pick

A strong candidate for mixed floors, with a mop that can stay in the dock for carpet-only runs. Check its current price against the Saros 20 rather than assuming the older robot is always cheaper. Reviewers liked its cleaning but still reported small obstacles it missed.

Saros 20

Worth considering when raised doorway thresholds keep a robot out of a room. Its stronger climbing claims come with specific test conditions, so measure the shape as well as the height. The reviews are less consistent on deep carpet and obstacle avoidance.

What reviewers found

Saros 10

T3 and Trusted Reviews both gave it top marks, and T3 called it the most accurate obstacle dodger it had tested, though TechRadar watched it chew a cable and try to eat a sock. Everyone liked its pickup: Trusted Reviews saw a flour spill on carpet almost vanish, and TechRadar found it cleared a cocker spaniel's hair for ten months without clogging. The mop is the weak spot, with Vacuum Wars scoring it well below average on dried stains, while T3 still cleared a milk and soy sauce spill in one pass.

Saros 20

TechRadar and RTINGS both found it excellent on hard floors, and TechRadar watched it learn to climb a chunky threshold between hall and living room. Carpet splits opinion: TechRadar was impressed with pet hair, but RTINGS called carpet pickup decent rather than exceptional. Avoidance splits them too, with Expert Reviews praising outstanding object avoidance while RTINGS found it inconsistent on carpet and unreliable with pet mess. TechRadar also noticed the dock's drying is audible.

Where they differ

  1. 01

    Climbing: the Saros 20's real advantage

    Roborock rates the Saros 10 for a 3cm single step or 4cm in total over a doorway threshold with two rises. The latter means two successive rises, not a single 4cm step. The Saros 20 lifts its body to clear about twice that over a threshold with two rises: 8.8cm by Roborock's figures, 8.5cm by TechRadar's. If raised doorway thresholds keep stranding your current robot, this is the reason to pay more.

    Saros 104cm
    Saros 208.5cm
  2. 02

    Carpet: the Saros 10 has more proof

    The Saros 10 can leave its mop in the dock for a carpet-only run. TechRadar found it kept rugs clear of dog hair over ten months. Reviews of the Saros 20 are more mixed on carpet. Check its current manual for carpet settings rather than treating a feature omitted from a review as proof that the feature is absent.

  3. 03

    Mopping: gentle pad against hotter spinning pads

    The Saros 10 uses a vibrating main pad and the Saros 20 uses two spinning pads. Their docks also wash at different claimed temperatures. A hotter dock wash is not proof of better stain removal on the floor. Compare the linked cleaning tests, especially if dried food or sticky spills are your main concern.

  4. 04

    Getting under furniture: same height, different trick

    Both are 7.98cm tall. The Saros 10 gets there by sinking its laser turret, which TechRadar says only helps under gaps of roughly 8cm to 11cm. The Saros 20 has no turret at all and navigates with cameras, so it stays low everywhere. Measure under your sofa before deciding this matters.

  5. 05

    Suction figures: bigger on paper

    Roborock quotes 22,000Pa for the Saros 10 and about 35,000–36,000Pa for the Saros 20. Those are claims, not cleaning results, and the reviews above tell you more about carpet and hard floors than the numbers do.

Questions people ask

Is the Saros 20 better than the Saros 10?

It adds climbing capability, but that does not make it a better purchase for every home. Reviews differ on carpet and obstacle avoidance. Compare the current price gap with the features your layout needs.

What is the difference between Saros 10 and Saros 20?

Climbing, navigation and mopping. The Saros 10 has a laser turret that sinks into the body and a single mop pad that detaches in the dock. The Saros 20 drops the turret for camera navigation, climbs about twice as high over doorway thresholds with two rises, and washes its two spinning mops at 100°C.

Which is better for carpet?

The Saros 10. Its mop detaches in the dock, so no damp pad crosses the carpet, and TechRadar found it kept on top of dog hair for ten months. RTINGS rated the Saros 20's carpet pickup decent rather than exceptional.

Why is the Saros 20's suction shown as a range?

Because two sources give different figures: Roborock's UK page says 36,000Pa and TechRadar says 35,000Pa. Rather than pick one, we show both ends. The same goes for its battery (6,300–6,400mAh) and its total climbing height over two rises (8.5–8.8cm).
