Ecovacs Deebot T90 Pro Omni vs Ecovacs Deebot T80 Omni
Quick take: The Ecovacs Deebot T80 Omni costs $251 less; the Ecovacs Deebot T90 Pro Omni has stronger suction (30,000 vs 18,000 Pa); the Ecovacs Deebot T90 Pro Omni runs longer per charge (350 vs 223 min).
Which one to buy
Fifty dollars separates them, and for most homes the T90 Pro Omni is the better use of it. Both are Ecovacs roller-mop robots with hot-water wash stations and LiDAR-plus-camera navigation, but the T90 is the newer design and it shows in the mopping. Its owners point to the second-highest dried-stain score one tester has recorded, perfect pet-hair pickup with zero tangles, and a run that avoided 23 of 24 test obstacles. Add a 350-minute runtime rating against the T80's 223 and 30,000 Pa against 18,000 Pa, and the T90 looks like the obvious step up.
The T80 Omni holds its ground on carpet. Testing found it removed 89% of embedded sand from deep carpet, and its owners praise the roller mop for cleaning up cooking spills without smearing. The T90's own owners call its carpet deep cleaning good rather than great, so a rug-heavy home loses less by saving the $50.
What tips it back is reliability. About 11% of T80 owners report outright bad experiences, including one on a second warranty replacement within seven months, and warranty claims draw complaints of months-long delays and surprise fees. Some T80 units also lose carpet recognition after a few weeks and start getting stuck on shag rugs, and early mop streaking is common until you turn the water flow down. The T90's complaints are milder: navigation is timid, skipping cluttered areas and hesitating at thresholds, its 250 ml bin is small, and Wi-Fi setup is fiddly. T90 owners also mention quality varying between units and slow support, so register either one the day it arrives.
Buy the T90 Pro Omni. The exception is a carpet-first home where $50 matters and you're willing to watch the T80 closely through its warranty period.
Ecovacs Deebot T90 Pro Omni
Worth it if you mop hard floors, have shedding pets, or want the stronger obstacle-avoidance record, and your home isn't so cluttered that its cautious navigation skips whole areas.
Ecovacs Deebot T80 Omni
The one to get if your floors are mostly carpet, the $50 saving matters, and you'll register the warranty and document any early faults right away.

Pros & cons

- ✓Perfect 100% pet hair pickup and 0% tangling from the ZeroTangle brush in 7-inch hair tests
- ✓Full-width 10.6-inch OZMO Roller 3.0 self-cleans continuously with 167°F water while it mops
- ✓Huge 350-minute runtime plus PowerBoost charging (10% in 3 minutes) covers very large homes

- ✗Small 250ml dustbin triggers frequent noisy auto-empty trips
- ✗Navigation efficiency is only slightly above average despite the new embedded LiDAR
- ✗Roller mop lifts just 15mm on carpet, so thick pile can still get damp
- ✗New for 2026, so long-term reliability feedback is still thin
Ecovacs Deebot T80 Omni

- ✓223-minute runtime in standard sweep mode covers most homes in one pass
- ✓20mm barrier-crossing height with the mop attached handles thicker thresholds
- ✗Sits awkwardly close in price and spec to the T80S Omni already in this catalog - check what's different before buying
- ✗Onboard water tanks (110ml/90ml) are small; you're leaning on the station for real capacity
- ✗0.22L dustbin needs the station bag for anything beyond a quick spot clean
- ✗No verified long-term owner reports available to confirm real-world reliability
Ecovacs Deebot T90 Pro Omni vs Ecovacs Deebot T80 Omni: common questions
Is the T90 Pro Omni worth $50 more than the T80 Omni?▾
For most buyers, yes. The T90's owners report standout mopping, zero hair tangles and better obstacle avoidance, while about 11% of T80 owners report bad experiences tied to reliability and slow warranty service. The T80 makes more sense only if carpet cleaning is your main concern.
Which handles thresholds and clutter better?▾
Neither is great. T90 owners say it hesitates at door thresholds, skips cluttered areas, and sometimes needs help moving between rooms. T80 owners report trouble on shag rugs once carpet recognition degrades after a few weeks. Open floor plans suit both better than busy ones.
How do I stop the T80 Omni's mop from streaking?▾
Owners who hit streaking mostly fixed it by lowering the water-flow setting, with several reporting success around a setting of 20 instead of the factory default. The T90's owners don't report the same problem, which is part of why its mopping rates higher.
