What the differences mean
Suction power
36,000Pa against 35,000Pa is a difference of only 1,000Pa, closer than the two numbers suggest; you would not tell these two flagships apart by feel.
Wi-Fi band
The Roborock Saros 20 connects on both 2.4 GHz and 5 GHz Wi-Fi. The Dreame X60 Ultra is 2.4 GHz only, which a few owners found more fiddly to pair on a combined dual-band router.
Warranty
Dreame backs the X60 Ultra with a three-year warranty, two years longer than the one year Roborock gives the Saros 20.
Smart home support timing
The Roborock Saros 20 already works with Apple HomeKit, Samsung SmartThings and Matter alongside Alexa and Google Home. The Dreame X60 Ultra lists those same three as an upcoming over-the-air update, not something usable today.
Mop tank and dock bag size
The Dreame X60 Ultra carries a 4.2L water tank and a 3.2L dock dust bag, both a little bigger than the Roborock Saros 20's 4L tank and 2.5L bag, so it goes slightly longer between refills and emptying.
Battery life
The Roborock Saros 20 is rated for 200 minutes per charge, ahead of the Dreame X60 Ultra's 165 minutes.
Which one to buy if
- value and the longest warranty coverage matter most
The Dreame X60 Ultra costs less, rates higher with owners, and carries three years of coverage against one.
- you want Apple Home or SmartThings working today, not as a future update
The Roborock Saros 20 already supports both; the Dreame X60 Ultra only lists them as an upcoming update.
- your router serves 5 GHz and you want the robot to use it
The Roborock Saros 20 connects on 5 GHz as well as 2.4 GHz; the Dreame X60 Ultra is 2.4 GHz only.
- you would rather refill the mop tank and empty the dock bag less often
The Dreame X60 Ultra's 4.2L tank and 3.2L dock bag are both a little bigger than the Saros 20's.

What owners say
Owners of both flagships name the same standout: a slim chassis that finally cleans under furniture nothing else could reach. Dreame X60 Ultra owners praise 35,000Pa of suction pulling up pet hair and dust other robots left behind, fast dual-camera mapping, and hot-water mop washing at the dock, while flagging an app that has refused to run units bought outside their intended region and a 2.4 GHz-only connection some found fiddly to pair. Roborock Saros 20 owners like an app that maps and splits rooms automatically, quiet overnight runs, and a built-in camera that doubles as a way to check on pets, but they are candid that no cleaning solution ships in the box, that threshold climbing is inconsistent, and that a handful of units arrived faulty.
