Robot Vacuums / eufy
eufy Robot Vacuum Omni S2
A 28 mm mop lift and a perfect obstacle score, wrapped around the emptiest suction claim here.
Overall score 7.3/10
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
eufy Robot Vacuum Omni S2 review: what the specs say
A 28 mm mop lift and a perfect obstacle score, wrapped around the emptiest suction claim here. At $1,399.99, eufy's 2026 model sits at the premium end of the category — the robot Vacuums we compare run from $139.99 to $1,399.99. It scores 7.3/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Obstacle Avoidance at 9.5/10 — real camera or structured-light recognition versus bump-and-turn, scored against published obstacle-course results rather than the number of object types claimed.. The weakest is Privacy & Control at 3.5/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: 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; and $1,399.99 makes it the most expensive robot on this page, and the $699 ECOVACS X11 mops far better. Every specification on this page comes from eufy's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Claimed Suction (Pa) | 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 | 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 | 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 | eufy markets pet-waste recognition as part of MatrixEye's 200+ object library but publishes no replacement guarantee |
| Mop System | HyperStream 2.0 roller mop at 240 rpm with 15 N down-pressure, washed continuously during the run |
| Mop Lift Over Carpet | 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 mm |
| Dock Type & Plumbing | 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 | 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 | 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 | 330 ml ml |
| Rated Runtime (and at what setting) | 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 min |
| Account, Cloud & Camera Privacy | 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 |
| Connectivity | Wi-Fi (eufy Clean app), Alexa |
| Material | Plastic; eufy publishes no housing material |
| Warranty | 12 months |
