Are the Yeedi S20, Dreame L60 models, and Ecovacs T90 Pro Omni all at the same Autonomy Ladder level?

No. The Yeedi S20 Infinity Ultra, Dreame L60 Ultra PE and Ecovacs Deebot T90 Pro Omni are classified Level III, Conditional Autonomy. The Dreame L60 Pro Ultra is classified Level IV: independent testing found it avoided shoes, socks and backpacks in a home whose floors were rarely clear, avoided 22 of 24 test obstacles, and never stalled or appeared at risk of getting stuck, while its dock emptied, washed and refilled with no extra input.

Which of these robots can lift its chassis over a raised threshold?

Only the Dreame L60 Pro Ultra has a documented leg-lift mechanism, ProLeap, independently tested crossing a threshold higher than its rated 45mm single-step spec; independent lab testing measured 51mm.

What evidence tier does each robot carry, and what does it mean?

On these records the Ecovacs Deebot T90 Pro Omni's evidence tier is verified, the two Dreame L60 models are provisional and the Yeedi S20 Infinity Ultra is pending. The T90 Pro Omni's own record states it carries no verified independent navigation testing, so its tier here does not mean the robot was independently tested more than the others.

Do any of these four robots have documented multi-year reliability data?

No. All four launched between February and May 2026, so none of the records cite independent long-term failure-rate data.

What separates the Dreame L60 Ultra PE from the L60 Pro Ultra?

The Pro Ultra adds ProLeap retractable legs for threshold crossing and a retracting LiDAR turret for low-furniture clearance. Independent lab testing measured the Ultra PE using less mop water but scoring below average on stain removal.
