iRobot Roomba, Roborock, and Ecovacs represent three very different bets on what a robot vacuum should be in 2026 — Roomba the pioneer clawing its way back from bankruptcy under new Chinese ownership, Roborock the engineering-obsessed premium leader, and Ecovacs the value-hunter's favorite that keeps sneaking flagship features into mid-range prices — and after digging through independent lab testing, owner reviews, and the brands' own spec sheets, the winner really does change depending on which one of those three stories you care about most. None of them is simply "the best." Each one is optimized for a different kind of buyer, and pretending otherwise is how people end up disappointed with an objectively good machine.
Why This Comparison Looks Different in 2026
This category went through more upheaval in the past twelve months than in the previous decade combined. iRobot — the company that invented the mainstream robot vacuum with the original Roomba in 2002 — filed for Chapter 11 bankruptcy in December 2025 after a failed Amazon acquisition attempt and years of losing ground to Chinese rivals. It was acquired in February 2026 by Picea Robotics, and against most expectations, the "new" iRobot came out swinging: eight redesigned Roomba models launched within months, headlined by the Roomba Max 775 Combo with 30,000Pa suction, ClearView Pro LiDAR with AI visual recognition, and an AutoWash dock.
Meanwhile Roborock and Ecovacs never stopped moving. Roborock's Saros 20 pushed suction to 36,000Pa and obstacle recognition past 300 object types, while Ecovacs quietly built the market's best value story with the Deebot T90 Pro Omni. Independent testers at Vacuum Wars, who buy every unit themselves rather than accepting review samples, have tracked all three brands closely through 2026, and their data is the backbone of what follows.
iRobot Roomba: The Comeback Story, With Real Caveats
The honest version of the Roomba story in 2026 is complicated. Under Picea's ownership, iRobot says nothing changes for existing customers, but several long-running Roomba lines (the J9+ Combo, the i3) have quietly been discontinued, and reviewers at Tom's Guide flatly say "now's not a good time to buy a Roomba" for anyone chasing the older lineup — the new range hadn't even finished rolling out in the US as of mid-2026.
What the new lineup gets right: the flagship Roomba Max 775 Combo nearly doubles the previous generation's suction (16,000Pa to 30,000Pa), adds pressurized hot-spray pre-treatment for dried-on messes, and pairs LiDAR with an AI camera system for obstacle recognition. At £799 (roughly $899 at current exchange rates, though US pricing hadn't been finalized at launch), it undercuts its own predecessor's £999 ceiling and puts real pressure on Roborock and Shark. The step-down Plus tier (models 575 through 675) brings the same ClearView Pro LiDAR with AI recognition down to sub-£400 prices, which is arguably the more interesting story for budget-conscious buyers who still want the Roomba name.
What hasn't changed: mopping remains Roomba's weak spot. iRobot only added serious mopping with the Combo series, and it still lacks the self-washing, hot-air-drying sophistication that Roborock and Ecovacs treat as standard on mid-range models, not just flagships. If your floors are mostly carpet and you mainly want reliable, well-supported vacuuming from a name your parents recognize, Roomba still earns its keep. If mopping matters, it's the weakest of the three brands here.
Roborock: The Engineering Flagship, at a Real Price
Roborock's Saros 20 is, by pretty much every independent measure available right now, the best all-around robot vacuum money can buy — and testers are not shy about saying so with real specifics attached. Gizmodo's reviewer called it "hands-down the best robot vacuum I've tested, and it's honestly not that close," while still flagging genuine quirks: it vacuumed up a USB-C cable during testing, occasionally misheard voice commands, and struggled slightly more with obstacle avoidance on patterned rugs than on bare floors.
The hardware backs up the hype. The Saros 20 packs 36,000Pa suction, a StarSight Autonomous System 2.0 that recognizes more than 300 obstacle types (Roborock's own materials cite the RGB camera correctly labeling things down to "footwear" and flagging office chairs as "easily trapped furniture"), and an AdaptiLift chassis that climbs double-layer thresholds up to 3.46 inches while staying just 3.13 inches tall — slim enough to clean under most sofas and beds. In Vacuum Wars' hands-on testing it avoided 17 of 24 test obstacles and posted a perfect score on the 7-inch hair-tangle test.
The catch is obvious: $1,599.99 MSRP in the US ($1,499 in the EU). That's premium-tier pricing for a premium-tier robot, and Roborock's own lineup below the Saros line (the Qrevo and Q series) covers most of the same core technology at $600–$1,000 if the absolute newest chassis engineering isn't a priority.
Ecovacs: The Value Play That Keeps Punching Up
If Roborock is chasing the ceiling, Ecovacs has spent 2026 quietly optimizing the floor — and the results are genuinely impressive for the money. The Deebot T90 Pro Omni, officially Ecovacs' mid-range flagship at $899.99 MSRP, won Vacuum Wars' "Value Robot Vacuum" award for June 2026 with a combined mopping score of 34.6, ahead of the category average of 20.3 and just behind Ecovacs' own $1,300+ X9 Pro Omni. Notebookcheck's independent German review went further, saying the T90's mopping "made many more expensive flagship models from the recent past pale in comparison."
The T90 runs AIVI 3D 4.0 obstacle recognition, 30,000Pa suction, an OZMO Roller 3.0 self-cleaning mop, and PowerBoost fast charging that recovers 10% battery in three minutes during routine dock visits — a genuinely clever way to extend runtime on large homes without a bigger battery. For buyers who want Ecovacs' true flagship tier, the X11 and X12 OmniCyclone models sit at $1,300–$1,500 with bagless docks and, on the X12, a pressurized water pre-wash feature nothing else in this comparison offers yet.
Where Ecovacs consistently loses points against Roborock: navigation efficiency and app polish. Multiple reviewers, including Notebookcheck and Vacuum Wars, flag inconsistent navigation and a lack of a dedicated mop-only mode as recurring T-series weaknesses. The honest read is that Ecovacs delivers flagship-adjacent cleaning performance at a real discount, but the software experience still trails Roborock's more mature app.

Which One Should You Actually Buy?
- Want the single best-performing robot regardless of price: Roborock Saros 20. It's the most consistently top-ranked machine across independent testing in 2026, and the threshold-climbing chassis solves a real problem the other two haven't matched yet.
- Want flagship-level cleaning without flagship pricing: Ecovacs Deebot T90 Pro Omni. It's currently the best dollar-for-dollar mopping performance in the category, according to independent lab data, at roughly half the Saros 20's price.
- Mostly carpet, minimal mopping needs, want US-based support and brand recognition: iRobot Roomba Max 775 Combo or one of the Plus-tier models. Just go in aware that the brand is mid-transition under new ownership, and hold off if you were eyeing a discontinued older model.
- Renting, small apartment, tight budget: None of the three flagships above make sense — look at the entry-level Roomba 115 (£229) or Roborock's Q-series instead, since none of this year's obstacle-avoidance or threshold-climbing upgrades matter much in a studio apartment.
Frequently Asked Questions
Is iRobot Roomba still a reliable brand to buy in 2026?
iRobot says existing customers see no change in support, and the new 2026 lineup brings genuine hardware upgrades. That said, the brand went through Chapter 11 bankruptcy in December 2025 and was acquired by Chinese manufacturer Picea Robotics in February 2026, and several older models have been discontinued. It's a real comeback, not a sure thing yet.
Is the Roborock Saros 20 worth $1,600?
If threshold-climbing, ultra-slim under-furniture cleaning, and best-in-class obstacle recognition matter to your specific home, independent testing supports the price. If you mainly want strong day-to-day cleaning, Roborock's own Qrevo and Q-series models deliver most of the core performance for hundreds less.
What is the best budget alternative to these three flagships?
Ecovacs' own lower T-series models (T50, T80) and Roborock's Q-series both bring LiDAR navigation and decent mopping under $500. Independent test data from Vacuum Wars generally rates these as better value than any flagship-tier robot for smaller homes.
Do any of these robot vacuums work with Matter smart home standards?
Roborock and Ecovacs have both announced future Matter support, and iRobot is expected to follow, but as of 2026 native Matter integration remains limited across all three brands — check current firmware notes before assuming compatibility.
