Saros 10R vs Saros 20

Buy the Saros 10R for most homes: it's better at avoiding clutter and pet accidents, and it targets stains automatically. Pay for the Saros 20 if raised doorway thresholds strand your robot or you have a shedding pet and lots of carpet, because it climbs about twice as high and lifts more hair.

Updated

The short version

Saros 10ROur pick

The safer all-rounder. It has no turret, so it's under 8cm tall everywhere, and it finished one lab's obstacle course without a single miss. RTINGS found it avoids pet waste consistently and spends extra time on dirty patches by itself. Its two spinning pads scrub dried stains well. What you give up: a lab found it needed several passes for hair buried in carpet, and it can only climb about half as high as the Saros 20.

Saros 20

Roborock's newer flagship, and its party trick is climbing. It lifts its body to get over a doorway threshold of about 8.5cm with two rises, roughly twice the 10R. Every test rated its hard floors highly, and RTINGS found it better than the 10R on carpet and pet hair. What you give up: RTINGS found it can't be trusted around pet accidents, and one home tester found cheaper robots do most of the job.

What reviewers found

Saros 10R

All three tests rate its hard floors, mopping and obstacle avoidance highly. Vacuum Wars gave it the first perfect score on its obstacle course, and RTINGS found it avoids pet waste consistently. Soy sauce, syrup and milk went in one pass for TechRadar. Carpet hair splits them: TechRadar called it one of the best robots for pet hair, but RTINGS found the brush needed several passes for embedded hair.

Saros 20

All four testers rated its hard-floor cleaning highly, and Expert Reviews got a perfect result in its standard tests. TechRadar was especially pleased with pet hair, and Expert Reviews saw it climb onto thick rugs without rucking them. Avoidance divides them: Expert Reviews called it the best it had tested, while RTINGS found pet-waste avoidance unreliable. Expert Reviews also felt cheaper robots do most of the job.

Where they differ

  1. 01

    Pet accidents and clutter: the 10R is safer

    RTINGS found the 10R avoids pet waste consistently, while the Saros 20 can't be trusted around pet accidents. Vacuum Wars recorded a perfect obstacle score for the 10R. The Saros 20's home results are better than its lab ones, with Expert Reviews calling its avoidance the best it had tested, but RTINGS found it inconsistent on carpet. If your pet sometimes has accidents, that settles it.

  2. 02

    Thresholds: the Saros 20 climbs about twice as high

    Roborock rates the 10R for 4cm over a doorway threshold with two rises. The Saros 20 lifts its body to clear about 8.5cm by TechRadar's figures, or 8.8cm by Roborock's, again over two rises rather than one tall step. If raised thresholds keep stranding your current robot, this is the reason to pay more.

    Climbing height over two rises
    Saros 10R1.6in (4cm)
    Saros 203.3in (8.5cm)
  3. 03

    Carpet and pet hair: the Saros 20 does better

    RTINGS found the Saros 20 cleans carpet and picks up pet hair better than the 10R. RTINGS saw the 10R need several passes for hair buried in carpet, though TechRadar, in a home full of dogs and cats, called it one of the best for pet hair. RTINGS still rated the Saros 20's general carpet pickup decent rather than exceptional, so keep a normal vacuum for deep cleans.

  4. 04

    Stains: the 10R hunts them down

    RTINGS found the 10R spots soiled areas and spends extra time on them automatically, which the Saros 20 doesn't. Both have two spinning pads and both mop well: TechRadar cleared soy sauce, syrup and milk in one pass, and Expert Reviews saw dried coffee and ketchup scrubbed away. The Saros 20's dock washes at a hotter claimed temperature.

  5. 05

    Same height, both turret-free

    Both are 7.98cm tall with no turret, so they stay low everywhere and navigate with built-in sensors. That's low for a robot with a full dock, but an advertised height isn't guaranteed clearance. Measure under your sofa and leave a little room for the robot to move.
