Side-by-Side Comparison
| Spec | ECOVACS DEEBOT X11 OmniCyclone | eufy RoboVac 11S MAX (T2126) |
|---|---|---|
| Price | $699.00 | $139.99 |
| Release Year | 2025 | 2019 |
| Claimed Suction (Pa) | 19,500 Pa claimed ('BLAST'). ECOVACS also publishes 38 CFM of airflow, which is the more meaningful number; Vacuum Wars separately measured 23 CFM at the nozzle, among the highest they have recorded. Airflow is comparable between brands in a way Pascals are not | 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: 100% pet-hair pickup, 0% tangling, 85% carpet deep clean, a 271-point combined mopping score against a 184 average, 0.7 g residual water (the driest finish they record), and 20 of 24 obstacles avoided. Ranked #14 in their 2026 Top 20 | 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 | AIVI 3D 3.0 — RGB camera plus 3D structured light driven by a vision-language model. Vacuum Wars' criticism is speed, not accuracy: the internal LiDAR maps slowly and needs several runs to settle | 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 | ECOVACS markets AIVI as recognising pet waste among 100+ object types but publishes no replacement guarantee if the robot drives through it | eufy makes no pet-waste claim for this model and it has no camera, so it cannot see waste at all |
| Mop System | OZMO Roller 2.0 — a high-density nylon roller at 200 rpm, continuously rinsed with clean water and scraped into a 2.7 L dirty-water tank as it cleans | None. Vacuum only |
| Mop Lift Over Carpet (mm) | 10 mm automatic lift on carpet detection (ECOVACS' own figure) — the lowest lift of the omni-dock robots here | Not applicable — no mop |
| Dock Type & Plumbing | OmniCyclone bagless auto-empty station with 3.2 L clean and 2.7 L dirty water tanks and an auto-fill module. No plumbing connection | Charging base only. No self-empty, no water, no plumbing |
| Dock Mop Wash & Dry | 167°F (75°C) hot-water roller washing with two solution tanks and a dirty-water sensor that triggers a re-wash and re-mop, then 2-4 hours of hot-air drying. You still empty and rinse the dirty-water tank yourself | Not applicable |
| Dock Bags & Running Cost | $0 a year in bags — the headline feature. The catch Vacuum Wars records is that damp debris cakes onto the inside of the cyclone bin, so you periodically scrub the station out by hand instead of throwing a bag away | 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) | 220 ml — roughly half a flagship's, so it leans hard on the station's 60-day rating | 600 ml, emptied by hand every 2-3 runs |
| Rated Runtime (and at what setting) (min) | ECOVACS claims up to 369 minutes on hard floor in standard mode with PowerBoost charging enabled — that figure includes mid-run recharges. Vacuum Wars' independent battery figure is 254 minutes, still the most efficient they have tested | Up to 100 minutes — eufy's figure is Standard mode on hard floor. BoostIQ on carpet cuts it |
| Account, Cloud & Camera Privacy | ECOVACS account required and maps are cloud-synced. The robot carries a camera with in-app remote viewing. At DEF CON in August 2024 researchers demonstrated taking over ECOVACS robots over Bluetooth and reaching the camera and microphone with no indicator light; ECOVACS patched it within weeks. One 2026 comparison also reports an optional ECOVACS premium plan at $2.99/mo for AI video monitoring — ECOVACS does not advertise this on its US product page and we could not confirm it | 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 | Black | Black, White |
Category Scores
Carpet Cleaning
The ECOVACS DEEBOT X11 OmniCyclone leads clearly here, 8.5 against 5.5 — a 3.0-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 eufy RoboVac 11S MAX (T2126) does not close the gap elsewhere.
Hard Floor & Edges
The ECOVACS DEEBOT X11 OmniCyclone leads clearly here, 8.5 against 6.5 — a 2.0-point margin on pickup on hard floor including crevices, edges and corners, and whether the side brush or mop actually extends to the skirting..

Pros & Cons
ECOVACS DEEBOT X11 OmniCyclone
Pros
- +Bagless cyclone station plus a full hot-water mop wash — the only dock here that does both
- +100% pet-hair pickup and 0% tangling in Vacuum Wars' bench test, with the driest mop finish they record
- +38 CFM published airflow, which is a genuinely comparable figure unlike the Pascal claims
- +$699 buys mopping that beats robots at twice the money
Cons
- −10 mm mop lift is the lowest of the omni-dock robots here — a plush rug will still get wet edges
- −220 ml bin is tiny, so a hairy house fills it inside one run
- −Bagless means periodically scrubbing caked damp debris out of the cyclone bin by hand
- −ECOVACS is the brand whose robots were publicly taken over at DEF CON 2024 with camera and mic access and no indicator light; patched, but it is the reason to think about where the camera is
- −Vacuum Wars rates its mapping as the slowest of the flagships — several runs before it settles
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
