The investigation
5 questions this comparison examines
How does each robot map and avoid obstacles?
LiDAR placement and obstacle-recognition scope vary across all four robots, with independent obstacle-avoidance testing published for two of the four records.
Yeedi S20 Infinity Ultra
Dreame L60 Ultra PE
L60 Pro Ultra Robot Vacuum
Ecovacs Deebot T90 Pro OmniVacuum Wars' independent lab review measured the L60 Pro Ultra's retracting turret and a 22-of-24 obstacle-avoidance score against a 16-of-24 category average.
Dreame's product documentation and Vacuum Wars' review credit the L60 Ultra PE's AI camera and 3D time-of-flight sensors with 220+ recognized object types.
Yeedi's and Ecovacs' own specification pages do not publish an independent obstacle-avoidance score for the S20 Infinity Ultra or the T90 Pro Omni.
Which robots have documented threshold-crossing capability?
This section looks at whether each robot's chassis crosses raised thresholds unassisted, and what independent testing found where it exists.
Yeedi S20 Infinity UltraDreame L60 Ultra PEL60 Pro Ultra Robot VacuumEcovacs Deebot T90 Pro OmniVacuum Wars measured the L60 Ultra PE crossing a 19mm threshold and failing at 25mm, and the L60 Pro Ultra's ProLeap legs exceeding their rated 45mm single-step spec at 51mm in testing.
Neither Yeedi's product documentation nor Ecovacs' T90 Pro Omni specification page publishes a chassis threshold-crossing rating for either robot.
How does each robot's mop system target stains?
Mop mechanisms range from a pre-spray nozzle system to roller pads with differing water use, with stain-removal results independently measured for two records.
Yeedi S20 Infinity UltraDreame L60 Ultra PEL60 Pro Ultra Robot VacuumEcovacs Deebot T90 Pro OmniYeedi's press release and product page describe FocusJet's pressurized pre-spray nozzles as a manufacturer capability; no independent stain-removal test of the S20 Infinity Ultra was found.
Vacuum Wars measured the L60 Ultra PE's stain removal below the category average and linked it to lower water use during mopping.
The same lab measured the L60 Pro Ultra using more water per mop pass than average, alongside a below-average combined mop score.
What does each robot's dock automate, and what stays manual?
Dock automation covers emptying, mop washing and drying across all four robots, but the specific wash temperature, detergent handling and manual steps differ.
Yeedi S20 Infinity UltraDreame L60 Ultra PEL60 Pro Ultra Robot VacuumEcovacs Deebot T90 Pro OmniEcovacs' T90 Pro Omni specification page documents a dirty-water flush step in the Omni station alongside 75C mop washing and heated air drying.
Dreame's after-sales and product pages describe both L60 docks washing mop pads with boiling water and dispensing detergent automatically; owners still manage water tanks.
Yeedi's product page lists weekly water-tank refill and periodic FocusJet nozzle inspection as owner tasks the self-empty station does not automate.
How much ownership-history evidence exists for each robot?
All four robots launched within the past six months, so the amount of independently documented ownership and failure history varies by weeks, not years.
Yeedi S20 Infinity UltraDreame L60 Ultra PEL60 Pro Ultra Robot VacuumEcovacs Deebot T90 Pro OmniRobovations classifies the T90 Pro Omni's evidence status as Verified and the other three as Provisional, reflecting differences in source depth (five source groups cited versus two to three) and time in market.
The S20 Infinity Ultra carries a New to Market readiness classification; the other three robots in this comparison are classified Ready Now.
None of the four records cite independent multi-year failure-rate or reliability data; all four launched between February and May 2026.
In closing
What the evidence shows
Patterns that emerged across the questions above.
All four sit at the same Autonomy Ladder rung
Yeedi S20 Infinity Ultra, both Dreame L60 variants, and the Ecovacs Deebot T90 Pro Omni classify at Level III, Conditional Autonomy; the differences sit in hardware and evidence depth, not autonomy tier.
Threshold-crossing evidence exists for only two records
Independent lab testing documents chassis threshold-crossing height for the two Dreame L60 models; the Yeedi and Ecovacs records carry no comparable independent measurement.
Evidence status splits three Provisional records from one Verified
The T90 Pro Omni is the only record classified Verified; the other three, all launched within the prior three to four and a half months, remain Provisional.
