Both robots run dual spinning mop pads, LiDAR, and self-cleaning docks, so the split comes down to execution details. The Dreame X60 Ultra pushes harder on mopping (15 N of pressure at 230 RPM), adds a second RGB camera plus an LED light for dark rooms, lifts its side brush over rugs, and backs it all with a three-year warranty. The Saros 20 counters with slightly higher suction, a bigger onboard dustbin, heated air drying at 131 °F, and a 20 mm mop lift that clears thicker carpet.
Two robots with nearly identical feature sheets can still feel very different in a real home, and that's what's happening here. The Dreame X60 Ultra and Roborock Saros 20 both use dual spinning mop pads, LiDAR mapping, AI obstacle avoidance with 3D structured light, and docks that empty the bin and wash the pads. Suction sits within 1,000 Pa of each other. So the decision lands on the smaller stuff: how each one sees in the dark, how much pressure it puts behind a mop pad, how tall a carpet it can clear, and how long the warranty runs.
Dreame X60 Ultra
out of 10Roborock Saros 20
The Dreame takes the overall rating 9.7 to 8.3, and the gaps show up in specific places. Navigation is the widest, 9.3 versus 7.3, helped by the second camera and the LED light for low-light rooms. Value comes in at 9.7 versus 7.4, which tracks with the Dreame also being the cheaper of the two. Cleaning goes 8.8 versus 7.6. Features land in a dead tie at 9.5 apiece, so neither one is short on capability.
Start with the eyes. The X60 Ultra runs dual RGB cameras plus an LED light, so it reads clutter in a dim hallway at night; the Saros 20 uses a single RGB camera with no light. Mopping tilts Dreame's way too, with 15 N of pressure against 13 N and 230 RPM against 200 RPM on the spinning pads, plus a slightly larger onboard water tank. But the Saros 20 lifts its mops 20 mm versus 10.5 mm, which matters if you own medium-pile rugs, and its dock dries the dust bag with heated air at 131 °F. Suction is essentially even at 36,000 Pa versus 35,000 Pa. Warranty isn't close: three years versus one.
Suction sits at 36,000 Pa for the Saros 20 and 35,000 Pa for the X60 Ultra, a difference you won't feel, and the Roborock's dustbin holds a bit more at 259 mL versus 235 mL. Both use a combination rubber and bristle main brush, which handles hard floors and carpet without much fuss.
Both run dual spinning mop pads, the strongest mainstream mopping setup available, but the Dreame spins faster (230 RPM versus 200 RPM) and presses harder (15 N versus 13 N) for scrubbing dried spills. The Saros 20 answers with a 20 mm mop lift, nearly double the Dreame's 10.5 mm, so it keeps pads clear of thicker carpet.
The Dreame's dock bag holds 3.2 L against 2.7 L, which means fewer bag changes during heavy shedding season. Suction is close enough between them that the bag size is the real differentiator for pet households.
Both use LiDAR with AI, camera, and 3D structured light obstacle avoidance, but the X60 Ultra adds a second RGB camera and an LED light so it identifies socks and cords in unlit rooms. That's the main reason it pulls ahead here, along with a liftable side brush that keeps bristles off rug edges.
Dreame's larger 3.2 L dust bag stretches the interval between changes, and the Saros 20 counters with heated dust bag drying at 131 °F to keep things fresh inside the dock. Both docks empty the bin and wash the mop pads automatically.
Nothing separates these two on runtime or coverage. Either one handles a typical multi-room floor plan and returns to recharge if it needs more time.
Identical here: built-in voice assistants plus Amazon Alexa, Google Assistant, and Apple support, along with no-go zones, multi-level maps, and smart obstacle avoidance on both. Whichever you pick, the app and voice experience covers the same ground.

The X60 Ultra wins on navigation hardware, mop scrubbing force, dust bag size, warranty length, and price, which is a lot of ground to give up. Go with the Saros 20 if thick rugs and heated dust bag drying rank high on your list. Otherwise, the Dreame is the easier call.
