Side-by-Side Comparison
| Spec | Dreame X50 Ultra | eufy Robot Vacuum Omni S2 |
|---|---|---|
| Price | $999.99 | $1399.99 |
| Release Year | 2025 | 2026 |
| Claimed Suction (Pa) | 20,000 Pa. For scale: Dreame's own 2026 flagship X60 Max Ultra claims 35,000 Pa, and Vacuum Wars still ranks the 30,000 Pa eufy Omni S2 below ECOVACS' T90 Pro Omni for mopping. The Pascal ladder is a marketing ladder | 30,000 Pa — the biggest claim on this page, and up from 8,000 Pa on the eufy Omni S1 it replaces. Vacuum Wars still scores its mopping about 20% below average, which is the whole argument against reading Pascals as a ranking |
| Independent Test Result | RTINGS and Vacuum Wars both bench this robot. Vacuum Wars' 2026 Top 20 is now led by its successors; the L50 Ultra, which uses the same ProLeap legs, sits at #8 at $799.99 | Vacuum Wars ranked it #3 overall in their 2026 Top 20 with a perfect 24/24 obstacle score and 87% carpet sand removal against 61% for the S1 — but its dried-stain mopping score of 82 points is about 20% below average, and they measured slower navigation than the S1 |
| Navigation & Obstacle Avoidance | LiDAR plus an AI RGB camera and 3D structured light, detecting up to 200 object types | 3D MatrixEye 2.0 — computer vision plus structured light recognising 200+ household objects. Perfect 24/24 in Vacuum Wars' obstacle course, matching the Roborock Saros 10R |
| What the Maker Promises About Pet Waste | Dreame lists pet waste among the recognised object types but publishes no replacement guarantee | eufy markets pet-waste recognition as part of MatrixEye's 200+ object library but publishes no replacement guarantee |
| Mop System | Dual spinning pads with a detachable mop module, so the mops can stay in the dock for a carpet-only run | HyperStream 2.0 roller mop at 240 rpm with 15 N down-pressure, washed continuously during the run |
| Mop Lift Over Carpet (mm) | 10.5 mm pad lift on carpet detection — Dreame's own figure, and notably lower than the Roborock Qrevo Curv's 17 mm or the eufy Omni S2's 28 mm despite the higher price | 28 mm (1.10 in) on carpet detection — nearly three times the ECOVACS X11's 10 mm and the only lift here that clears a thick pile rug |
| Dock Type & Plumbing | Self-empty, mop wash, hot-air dry and automatic solution refill. No plumbed connection on the standard kit | Self-empty, hot-water mop wash, hot-air dry, water electrolysis and auto detergent dosing. A separate Auto Refill & Drainage version plumbs into a supply and drain; the standard dock does not |
| Dock Mop Wash & Dry | Up to 80°C (176°F) hot water with four selectable temperatures, an AceClean DryBoard washboard with 20 spray nozzles that rinses itself, then automatic hot-air drying. The dirty-water tank is still emptied by hand | 140°F (60°C) heated wash — TechRadar reports 70°C — then 131°F (55°C) hot-air drying, with built-in water electrolysis (Eco-Clean ozone) and automatic detergent dosing. Sources conflict on the wash temperature; eufy quotes both. The dirty-water tank is still emptied by hand |
| Dock Bags & Running Cost | 3.2 L proprietary bag rated by Dreame at 100 days, so roughly 3-4 bags a year. Two bags and 200 ml of cleaning solution are in the box, along with spare mop pads, main brush and side brush | 2.5 L bag with a 68-day rating, so roughly 5-6 bags a year. TechRadar describes the base as taking generic 2.5 L dust bags rather than a locked proprietary part, which if it holds is a meaningful saving over Roborock and iRobot. Add detergent and fragrance capsules, which are eufy-branded consumables |
| Robot Bin Capacity (ml) | 395 ml — among the largest onboard bins here | 330 ml |
| Rated Runtime (and at what setting) (min) | Up to 220 minutes, and Dreame states the condition in the same sentence: quiet mode, vacuuming and mopping. Coverage up to 205 m² per charge | Up to 180 minutes across four modes (Quiet, Standard, Turbo, Max) — eufy's figure is the quiet mode. Vacuum Wars measured slower navigation efficiency than the cheaper S1 it replaces |
| Account, Cloud & Camera Privacy | Dreamehome account required and maps are cloud-synced. Camera on board with in-app remote viewing; independent privacy write-ups report Dreame processes obstacle-avoidance images on-device by default | eufy account required and maps are cloud-synced. Camera on board with remote viewing. eufy is the brand that marketed local-only storage on its security cameras and was then caught uploading footage to the cloud unencrypted, and privacy write-ups note eufy's policy allows sharing personal identifiers with advertising partners — hold its privacy marketing to a higher burden of proof than most |
| Warranty | 36 months | 12 months |
| Colors | White, Black | White |
Category Scores
Carpet Cleaning
The eufy Robot Vacuum Omni S2 leads clearly here, 9.0 against 8.5 — a 0.5-point margin on embedded-debris and pet-hair pickup from carpet in independent bench tests, plus anti-tangle brush design — not the manufacturer's Pascal claim.. If that is what you are buying for, the Dreame X50 Ultra does not close the gap elsewhere.
Hard Floor & Edges
The eufy Robot Vacuum Omni S2 leads clearly here, 8.5 against 8.0 — a 0.5-point margin on pickup on hard floor including crevices, edges and corners, and whether the side brush or mop actually extends to the skirting.. If that is what you are buying for, the Dreame X50 Ultra does not close the gap elsewhere.
Mopping
The Dreame X50 Ultra leads clearly here, 8.0 against 6.5 — a 1.5-point margin on whether the mop scrubs or just drags: pad versus spinning versus washed roller, down-pressure, dried-stain removal and how wet the floor is left. Vacuum-only robots score 0.. If that is what you are buying for, the eufy Robot Vacuum Omni S2 does not close the gap elsewhere.
Obstacle Avoidance
The eufy Robot Vacuum Omni S2 leads clearly here, 9.5 against 8.0 — a 1.5-point margin on real camera or structured-light recognition versus bump-and-turn, scored against published obstacle-course results rather than the number of object types claimed.. If that is what you are buying for, the Dreame X50 Ultra does not close the gap elsewhere.
Dock Automation
The eufy Robot Vacuum Omni S2 leads clearly here, 9.5 against 9.0 — a 0.5-point margin on how much the dock genuinely does unattended: self-empty, hot-water mop wash, hot-air dry, solution dosing, plumbed refill and drain — minus the jobs it still leaves you.. If that is what you are buying for, the Dreame X50 Ultra does not close the gap elsewhere.
Running Cost
The Dreame X50 Ultra leads clearly here, 7.0 against 6.5 — a 0.5-point margin on the trap dimension. What the machine costs to feed each year in proprietary bags, mop pads, filters and detergent, and whether a bagless dock lets you spend nothing at all. 10 means it costs nothing to keep running.. If that is what you are buying for, the eufy Robot Vacuum Omni S2 does not close the gap elsewhere.
Privacy & Control
The Dreame X50 Ultra leads clearly here, 5.5 against 3.5 — a 2.0-point margin on whether an account and cloud are required, where the maps live, whether there is a camera and where its frames are processed, and the brand's actual privacy and security record.. If that is what you are buying for, the eufy Robot Vacuum Omni S2 does not close the gap elsewhere.
Value
The Dreame X50 Ultra leads clearly here, 8.5 against 5.5 — a 3.0-point margin on tested cleaning performance and dock automation against the real street price and the year-one consumables bill.. If that is what you are buying for, the eufy Robot Vacuum Omni S2 does not close the gap elsewhere.

Pros & Cons
Dreame X50 Ultra
Pros
- +ProLeap legs clear a 6 cm obstacle — no other robot on this page climbs anything close
- +A three-year warranty on Dreame's own US page against one year from Roborock, iRobot, ECOVACS, Shark and eufy
- +395 ml bin and a 100-day bag rating mean very little hands-on maintenance
- +Detachable mop module means carpet runs happen with no damp pad anywhere near the rug
Cons
- −10.5 mm mop lift is low for a $1,000 robot — the $849 Roborock Qrevo Curv lifts 17 mm
- −The 20,000 Pa headline is already two rungs down Dreame's own ladder (the X60 Max Ultra claims 35,000 Pa) for no measured cleaning reason
- −Sources conflict on the warranty: Dreame's product page says 3 years, a published warranty comparison says 1 year extendable to 2 with registration inside 30 days
- −Big, tall dock; this is not the robot for a small flat
- −Camera with remote viewing and a China-based cloud account, with no published on-device-processing guarantee from Dreame itself
eufy Robot Vacuum Omni S2
Pros
- +28 mm mop lift is in a different league — this is the one robot here you can run on a plush rug without wetting it
- +Perfect 24/24 obstacle score and 87% carpet sand removal, both at the top of Vacuum Wars' 2026 rankings
- +42 mm threshold clearance handles doorway transitions that stop most of this field
- +Fully automated dock: electrolysed water, auto detergent dosing, hot wash and hot dry
Cons
- −The 30,000 Pa headline is the largest claim here and Vacuum Wars scores its mopping about 20% below average — the clearest single proof that Pascals do not predict cleaning
- −$1,399.99 makes it the most expensive robot on this page, and the $699 ECOVACS X11 mops far better
- −eufy's own wash-temperature claim varies between 60°C and 70°C depending on where you look
- −eufy's privacy record is the weakest here: it was caught uploading security-camera footage after marketing local-only storage
- −Vacuum Wars found navigation efficiency slower than the cheaper S1 and threshold climbing inconsistent above 32 mm
