Side-by-Side Comparison
| Spec | eufy Robot Vacuum Omni S2 | eufy RoboVac 11S MAX (T2126) |
|---|---|---|
| Price | $1399.99 | $139.99 |
| Release Year | 2026 | 2019 |
| 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 | 2,000 Pa claimed by eufy. Sources conflict: TechGearLab's spec table for this same model lists 1,300 Pa, which is the figure for the older non-MAX 11S. Either way the number is a marketing figure, not a measurement you can compare across brands |
| 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 | TechGearLab: 90% hard-floor debris pickup, 6.8/10 carpet, but 3.4/10 for navigation and obstacle avoidance. Overall 55/100, 18th of 23 robots tested |
| 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 | Bump-and-turn random navigation. Front bumper and infrared cliff sensors only — no LiDAR, no camera, no map, no no-go zones |
| 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 | eufy makes no pet-waste claim for this model and it has no camera, so it cannot see waste at all |
| Mop System | HyperStream 2.0 roller mop at 240 rpm with 15 N down-pressure, washed continuously during the run | None. Vacuum only |
| Mop Lift Over Carpet (mm) | 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 | Not applicable — no mop |
| 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 | Charging base only. No self-empty, no water, no plumbing |
| 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 | Not applicable |
| 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 | No bags at all, so $0/yr in dock consumables. Recurring parts are a washable filter, a rolling brush and side brushes; eufy and third parties both sell refill kits for the 11S/15C/30 family |
| Robot Bin Capacity (ml) | 330 ml | 600 ml, emptied by hand every 2-3 runs |
| Rated Runtime (and at what setting) (min) | 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 | Up to 100 minutes — eufy's figure is Standard mode on hard floor. BoostIQ on carpet cuts it |
| 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 | No account, no cloud, no camera, nothing leaves the house. The price is no map, no zones and no scheduling beyond the remote's daily timer |
| Warranty | 12 months | 12 months |
| Colors | White | Black, White |

Pros & Cons
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
eufy RoboVac 11S MAX (T2126)
Pros
- +Under $150 street with no app, no account and no Wi-Fi — there is genuinely nothing to sign up for
- +90% hard-floor pickup in TechGearLab's test, better than the price suggests
- +72 mm tall, so it clears kick-boards and bed frames every dock-equipped robot here is too fat for
- +Zero proprietary consumables: no bags, no pads, no detergent — the cheapest robot here to keep running
Cons
- −A 2019 design still on sale in 2026 — bump navigation means no map, no no-go zones and no memory of where it has been
- −TechGearLab scored navigation and obstacle avoidance 3.4/10; it eats cables and strands itself
- −eufy's 2,000 Pa claim is unverifiable and TechGearLab's own spec table records 1,300 Pa for the same robot
- −No mop and no self-empty base — you empty a 600 ml bin by hand every two or three runs
- −Street price swings between roughly $140 and the $279.99 list, so buying at list is a bad deal
