Pros & cons

Ecovacs Deebot T20 Omni

  • Hot water mop washing at $800 undercuts competitors significantly
  • OZMO Turbo dual spinning mops clean hard floors effectively
  • 260-minute battery handles very large homes
  • Auto mop lifting at 9mm keeps carpets dry
  • 2-year warranty provides good peace of mind
  • No obstacle avoidance — bumps into furniture, cables, and toys
  • ECOVACS app connectivity issues persist for some users
  • 6000Pa suction is adequate but falls behind newer models
  • Robot is on the heavy side at 10.6 lbs

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)
