Pros & cons
Ecovacs Deebot T80S Omni
- ✓Exceptional raw power for the price - Vacuum Wars measured 2.44 kPa suction, about 2.5x the category average, with a 91% carpet deep-clean score
- ✓Perfect 100% pet hair pickup and zero tangles in seven-inch hair tests thanks to ZeroTangle 3.0
- ✓Self-rinsing OZMO Roller 2.0 posted a 30.5 combined mopping score (20.3 average) while leaving almost no water behind
- ✓Strong AIVI 3D obstacle avoidance (21 of 24 test objects) using structured light, RGB camera, and LED assist
- ✓OMNI station washes the mop with 167°F water, dries with heated air, and holds up to 90 days of debris in a sealed 3L bag
- ✗Below-average navigation efficiency - the embedded mini-ToF LiDAR covers ground more slowly than top-mounted turret designs
- ✗Threshold climbing tops out around 0.8 inches, so raised transitions can strand it
- ✗Uses the older OZMO Roller 2.0 rather than the 3.0 mop found on the pricier T90 Pro Omni
- ✗US availability only began around May-June 2026, so the review base is thin - the 4.4 rating and ~80 review count are honest estimates (Vacuum Wars scored it 4.17/5)
Ecovacs Deebot T90 Max Plus Omni
- ✓40,000 Pa suction, the same rating as the T90S Pro
- ✓212°F hot-water roller wash and hot-air drying
- ✓Roller lifts 15 mm on carpet
- ✓ZeroTangle 4.0 anti-tangle brush
- ✓TruEdge 3.0 edge cleaning
- ✓95 mm body height
- ✗Station uses 2.5 L dust bags, an ongoing cost
- ✗Runtime, bin size, noise, weight, warranty and obstacle-avoidance hardware are not published
- ✗$300 more than Ecovacs' T50 Pro Omni, which also washes its mop with hot water
