Dreame X50 Ultra Complete vs Roborock Saros 10

Which is better, Dreame X50 Ultra Complete or Roborock Saros 10?

Buy the Dreame X50 Ultra Complete unless most of your floor is carpet.

Updated

The short version

X50 Ultra CompleteOur pick

The better choice if your home has raised doorway thresholds or you prioritise mopping. Its lifting legs help it cross the raised strips between rooms. Dreame claims up to 6cm in total where the threshold has two rises, rather than one vertical step. One home tester called its mopping the most thorough it had tried. You give up some carpet and fine-dust pickup, the battery runs down faster than claimed, and the dock takes a fair bit of floor.

Saros 10

The one to buy if your home is mostly carpet, especially with a shedding pet. It's strong on hair, its mop comes off in the dock, it's a touch lower for getting under sofas, and one tester ran it for ten months without fuss. Its claimed climbing limit is lower, at 4cm over a threshold with two rises, and its mop is gentle on dried stains.

What reviewers found

X50 Ultra Complete

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.

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.

Where they differ

  1. 01

    Climbing: 6cm against 4cm

    Dreame rates the X50 Ultra Complete for thresholds with two rises totalling up to 6cm. This means two successive rises, not a single 6cm step. Its small lifting legs help it climb, and Tech Advisor saw it cross a bedroom threshold that had stopped other robots. The Saros 10 is rated for 4cm over a threshold with two rises. The X50's way down is less graceful: TechRadar called the landing an alarming crash.

    Mopping: the X50's strong suit

    TechRadar found the X50's mopping the most thorough it had tried, with one pad reaching out to clean along skirting boards. The Saros 10's single vibrating pad is gentle, and Vacuum Wars found it weak on dried stains unless you turn the settings up. RTINGS was less sure about the X50 on old stains, so expect to help with set-in marks either way.

  3. 03

    Carpet and pet hair: the Saros 10 is safer

    Everyone who tested the X50 found carpet its weaker side, and RTINGS said it couldn't lift deeply embedded pet hair. The Saros 10 kept a cocker spaniel's hair under control for ten months in TechRadar. Both keep rugs dry: the Saros 10 leaves its mop in the dock, and the X50 lifts its pads or can drop them off.

  4. 04

    Under furniture: the Saros 10 is lower

    Both sink their laser towers to get under sofas. That leaves the Saros 10 at 7.98cm and the X50 at 8.9cm. If the gap under your sofa is around 8cm to 9cm, only the Saros 10 will fit.

Questions people ask

Is Dreame or Roborock better?

Neither brand wins outright. On these two models, the Dreame climbs higher and mops better according to TechRadar, while the Roborock is stronger on carpet and pet hair and has a ten-month test behind it from TechRadar.

Which is better value?

It depends on today's prices, which are listed above. The X50 Ultra Complete has been discounted since Dreame's newer X60 models arrived, and it gives you the higher climb and the stronger mopping. The Saros 10 earns its place if carpet and pet hair are your main job.

Do both work on carpet?

Yes. The Saros 10 detaches its mop in the dock, and the X50 Ultra Complete lifts its pads or can drop them off, which Tech Advisor notes. For deep carpet and pet hair, the Saros 10 did better in testing: RTINGS found the X50 couldn't lift deeply embedded hair.
