Roborock Saros 10R vs Dreame X50 Ultra

Buy the Saros 10R unless raised doorway thresholds keep stopping your robot. In the UK, where Roborock doesn't sell the 10R, the X50 Ultra is the one you can get.

Updated

The short version

Saros 10ROur pick

The stronger cleaner on hard floors. It has no turret, so it's 7.98cm tall everywhere, and the lab that tested both found it cleaned edges and mopped better than the X50. It also scored a perfect run on one obstacle course. What you give up: its climbing claim is lower, a stack of books beat it at home, and Roborock's UK store doesn't list it.

X50 Ultra

The one for homes with raised doorway thresholds. Small lifting legs help it over the strips between rooms, and both home testers loved its mopping. What you give up: a lab found it rushed past fine dust and edges and rated its stain cleaning mediocre, it's taller under furniture, and one tester averaged only about 90 minutes per charge. In the UK it's sold as the X50 Ultra Complete, the same robot with extra spare parts.

What reviewers found

Saros 10R

All three tests rate its hard floors, mopping and obstacle avoidance highly. RTINGS found it left almost nothing along walls and in corners, and Vacuum Wars gave it the first perfect score on its obstacle course. Soy sauce, syrup and milk went in one pass for TechRadar. Carpet hair splits them: TechRadar, in a home full of dogs and cats, called it one of the best robots for pet hair, but RTINGS found the brush needed several passes to lift embedded hair. At home, a stack of books also beat it at a threshold test.

X50 Ultra

Tech Advisor watched it climb a bedroom threshold that had beaten plenty of other robots, and TechRadar called its mopping the most thorough it had experienced. The lab test was cooler: RTINGS found it fast but careless with fine dust and edges on hard floors, and rated its stain cleaning mediocre, while both home testers found floors spotless. Everyone agrees carpet is its weaker side, and TechRadar averaged only about 90 minutes per charge. RTINGS tested the plain X50 Ultra, which is the same robot with fewer spare parts.

Where they differ

  1. 01

    Climbing: the X50's real advantage

    Dreame rates the X50 for 6cm in total over a threshold with two rises, and Roborock rates the 10R for 4cm. Neither figure is a single step. Tech Advisor saw the X50 climb a bedroom threshold that had stopped other robots, while a stack of books beat the 10R for TechRadar. The X50's way down is noisy: TechRadar called the landing an alarming crash.

    Climbing height over two rises
    Saros 10R1.6in (4cm)
    X50 Ultra2.4in (6cm)
  2. 02

    Hard floors: the 10R is more thorough

    RTINGS found the 10R picked up fine, medium and large debris and left almost nothing along walls and in corners. In the same lab, RTINGS found the X50 moved too fast, missing fine material and barely using its extending brush in corners. The X50's home testers were happier, so the gap shows most with fine dust and skirting boards.

  3. 03

    Mopping: both good, the 10R steadier

    Home testers loved both mops. TechRadar called the X50's the most thorough it had seen, and TechRadar saw spills go from the 10R in one pass. The lab split them: RTINGS rated the 10R's mopping great, while RTINGS rated the X50 mediocre on stains, needing several passes. Vacuum Wars also scored the 10R well above average on dried stains.

  4. 04

    Obstacles: the 10R has the cleaner record

    Vacuum Wars gave the 10R a perfect obstacle score, and RTINGS found it great at avoiding pet waste. RTINGS also found the X50 very good with pet waste, but TechRadar saw it miss socks and short wires and hit fake pet mess until Pet mode was on. Pick up cables before running either.

  5. 05

    Under furniture: the 10R is lower

    The 10R has no turret and stands 7.98cm tall. The X50 sinks its laser tower to reach 8.9cm. If the gap under your sofa is around 8cm to 9cm, only the 10R will fit, so measure first and leave a little room for uneven floors.

    Lowest height
    Saros 10R3.1in (8cm)
    X50 Ultra3.5in (8.9cm)

Questions people ask

Is the Saros 10R better than the Dreame X50 Ultra?

For most homes, yes. The same lab tested both, and RTINGS found the 10R cleaner at the edges and better at mopping than RTINGS found the X50. The X50 is the better climber, so it wins if raised thresholds are your problem.

Which is better for carpet and pet hair?

Neither stands out. RTINGS and RTINGS both found their robot struggled to lift hair embedded in carpet. At home, TechRadar rated the 10R one of the best for pet hair, while TechRadar found powder left in the X50's carpets. Keep a proper vacuum for deep carpet with either.

X50 Ultra or X50 Ultra Complete?

It's the same robot. The Complete bundle adds extra pads, brushes and filters, and the plain X50 Ultra is the US name. RTINGS tested the X50 Ultra, and Tech Advisor and TechRadar tested the Complete.

Can I buy the Saros 10R in the UK?

Not from Roborock's UK store, which doesn't list it. It's sold in the US and much of Europe. In the UK, the X50 Ultra Complete is the one of these two you can buy new, and the prices above show what's on offer where you are.

Can both leave their mops in the dock for carpet?

Yes. The 10R's pads stay in the dock for vacuum-only runs, which TechRadar confirms. The X50 lifts its pads over rugs and, as Tech Advisor notes, can drop them off automatically if you're worried about damp carpet.
