Side-by-Side Comparison
| Spec | iRobot Roomba Max 705 Combo Robot + AutoWash Dock | eufy Robot Vacuum Omni S2 |
|---|---|---|
| Price | $899.99 | $1399.99 |
| Release Year | 2025 | 2026 |
| Claimed Suction (Pa) | iRobot publishes no Pascal figure. Its claim is '175x more suction' than a Roomba 600 in spot-clean mode. One third-party spec database lists 13,000 Pa; iRobot has never confirmed it, so treat both numbers as unverified | 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 | Homes & Gardens tested it for a month in a pet household: 'one of the best mopping systems around' on hard floor, but it repeatedly left both short and long pet hair behind and scattered fine debris like sugar and lentils, needing a second pass | 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 | ClearView Pro LiDAR builds 3D maps and names rooms automatically; PrecisionVision AI cameras are trained on cords, socks and pet waste. Homes & Gardens rated obstacle avoidance and mapping as a genuine strength | 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 | iRobot's P.O.O.P. Promise — replace the robot free if it fails to avoid solid dog or cat waste, valid 1 year from purchase, replacement product only, additional terms apply — is still written on iRobot's US page against the Roomba j7+, not against this model. Confirm coverage in writing before buying it for that reason | eufy markets pet-waste recognition as part of MatrixEye's 200+ object library but publishes no replacement guarantee |
| Mop System | PowerSpin roller mop at 200 rpm with heated mopping and a SmartScrub back-and-forth deep-scrub mode | HyperStream 2.0 roller mop at 240 rpm with 15 N down-pressure, washed continuously during the run |
| Mop Lift Over Carpet (mm) | It does not lift a pad at all — a retractable cover closes over the wet roller when the robot moves onto carpet. iRobot publishes no clearance height in millimetres, so there is no number to compare with the 10-28 mm lifts elsewhere here | 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 | AutoWash dock — self-empty, heated mop wash and dry, automatic solution dosing and a dock self-clean cycle. No plumbed refill or drain option | 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 | Heated wash and heated dry with automatic StayClean concentrate dosing and a self-clean cycle. iRobot does not publish the water temperature, unlike Roborock (80°C), Dreame (80°C), ECOVACS (75°C) and eufy (70°C) | 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 | Proprietary iRobot bags rated at 75 days. iRobot's own 3-pack for AutoEmpty/AutoWash docks is $19.99, roughly $32 a year, plus StayClean solution and roller mop replacements. iRobot's Select subscription, which bundled supplies and hardware from $29/month, has been closed to new customers since January 2024 — a 2026 subscription round-up still lists it as available at $29.99/mo | 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) | Not published by iRobot | 330 ml |
| Rated Runtime (and at what setting) (min) | Not published by iRobot, whose spec sheet says only 'lithium-ion battery'. One third-party spec database lists 150 minutes | 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 | iRobot account and iRobot Home app required; maps are cloud-stored with deletion on request. Two AI cameras on board. iRobot's 2022 MIT Technology Review episode — development-unit images, including a woman on a toilet, leaking out of a data-annotation contractor — is the reason buyers ask this question; iRobot says production robots do not send photos without permission. iRobot filed Chapter 11 on 14 December 2025 and now belongs to Picea, and says apps and warranties continue | 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 | 12 months | 12 months |
| Colors | White, Black | White |

Pros & Cons
iRobot Roomba Max 705 Combo Robot + AutoWash Dock
Pros
- +Homes & Gardens rates the mopping as among the best they have used — the heated roller plus AutoWash dock is the closest thing here to a manual mop
- +The retractable roller cover is a smarter answer to carpet than a pad that lifts a few millimetres
- +The only camera robot here whose maker publishes a written pet-waste replacement promise at all, even if it names an older model
- +US support network, 60-day trial, and the most mature app in the category
Cons
- −Homes & Gardens found it repeatedly left pet hair behind and scattered fine debris — poor value against $699 rivals for vacuuming
- −iRobot publishes no suction figure, no runtime, no bin capacity and no dock water temperature for this robot
- −The P.O.O.P. Promise on iRobot's US site names the discontinued j7+, not the Max 705
- −Roughly $32/yr in proprietary bags plus StayClean concentrate, the most expensive dock here to feed
- −Bulky robot and a very large dock, and iRobot is only just out of a Chapter 11 restructuring under new ownership
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
