Quick Answer: For most buyers in 2026, the Ecovacs Deebot T90 Pro Omni is the stronger buy — Vacuum Wars scored it 4.16/5 with a perfect 100% pet-hair pickup and a 157/184 mopping score, the second-highest the lab has ever recorded, all for $799.99-$899.99. iRobot’s Roomba Max 705 Combo finally ships with LiDAR and cleans in total darkness, and its 200 RPM PowerSpin mop earned praise for near-manual hard-floor results — but it costs $1,299.99, and disappointing pet-hair pickup is the most consistent criticism across hands-on reviews. Buy Ecovacs for the stronger tested cleaning performance at a lower price; buy Roomba if overnight cleaning without lights on is the priority.

Roomba and Ecovacs took different paths to their current 2026 flagships. iRobot spent years defending camera-only navigation and just gave in — the Max 705 is its first LiDAR-equipped current-generation robot. Ecovacs, meanwhile, quietly let a mid-range T-series model outscore its own pricier X-series flagships on nearly every measured category. Both are already reviewed in full on this site — here’s the side-by-side.

Ecovacs Deebot T90 Pro Omni — best tested cleaning performance

iRobot’s headline change is LiDAR, and it matters: the Max 705’s ClearView Pro system maps roughly 1,000 sq ft in 9 minutes per iRobot and, unlike the camera-navigating Roombas it replaced, works in total darkness. The Ecovacs T90 Pro Omni skips LiDAR entirely for a single AI camera plus 3D structured light — a setup that generally needs some ambient light to work reliably, but that Vacuum Wars still scored at 23/24 on obstacle avoidance, well above the 16/24 category average. If you want to schedule overnight cleaning with the lights off, only the Roomba’s LiDAR can do that reliably. If your home has normal daytime lighting, the Ecovacs system is dodging clutter about as well as anything else on the market.

Pet hair: not close

This is where the gap is starkest. Vacuum Wars measured a perfect 100% pet-hair pickup on the T90 Pro Omni, plus a perfect 0% hair-tangle rate on its 7-inch hair test using Ecovacs’ ZeroTangle 4.0 brush system. The Max 705 wasn’t run through the same lab, but reviews.org measured roughly 80% overall clearance against a 90-95% industry norm, and disappointing pet-hair pickup is described as “the criticism that recurs across hands-on reviews” of this specific model — a real regression from the Roomba Combo 10 Max it replaced, which held a perfect Vacuum Wars pet-hair score.

Mopping: strong on both sides, harder numbers for Ecovacs

The Max 705 Combo’s 200 RPM PowerSpin roller mop with PerfectEdge extension earned genuine praise — Homes & Gardens called its hard-floor results “as close to a deep manual mop clean” as it has tested from a robot, backed by an AutoWash dock that heat-washes and heat-dries the roller and auto-dispenses cleaning solution. The T90 Pro Omni counters with actual lab numbers: 157 out of 184 on Vacuum Wars’ dried-on stain test, the second-highest score the lab has ever recorded, while leaving just 0.35g of water residue behind versus a 1.1g average — genuinely strong scrubbing without over-wetting floors. Both systems are among the best mopping setups reviewed on this site; the difference is that Ecovacs’ result is a standardized lab score and Roomba’s is a hands-on impression.

Price and value

The gap here is straightforward: the Roomba Max 705 Combo lists at $1,299.99, while the Ecovacs Deebot T90 Pro Omni lists at $799.99 (Vacuum Wars’ own test unit ran $899.99) — roughly $400-500 less for a robot that currently has the stronger lab-tested numbers across pet hair, mopping, and obstacle avoidance. iRobot’s cheaper Max 705 Vac at $899.99 closes some of that gap for buyers who skip mopping entirely, but it still trades away Ecovacs’ near-perfect cleaning scores for LiDAR navigation alone.

The bottom line

The Ecovacs Deebot T90 Pro Omni is the stronger all-around performer on the numbers available in 2026 — a perfect pet-hair score, near-record mopping, and excellent obstacle avoidance, all for $400-500 less than iRobot’s flagship. The Roomba Max 705 Combo answers with one genuine advantage: LiDAR that maps and cleans in a fully dark house, something the Ecovacs’ camera-based system can’t match, plus a roller-mop system that testers rate as close to a manual clean. If dark-room cleaning or brand loyalty to iRobot’s mop system matters most, the Roomba is worth its premium. For most buyers chasing the strongest tested cleaning performance per dollar, Ecovacs wins this matchup.
