Yeedi S20 Infinity Ultra
Yeedi's stain-targeting approach differentiates it from category norms, but shipping data remains thin. Flagship pricing reflects that positioning; first-year reliability feedback will determine whether the FocusJet system justifies the premium.

Will the Yeedi S20 Infinity Ultra work in your home?
Describe your home using the controls. Each choice reads the spec sheet for you, flagging where the Yeedi S20 Infinity Ultra is built for your space and where it isn’t.
A classification of fit for the conditions you set, not a recommendation. Verdicts describe engineering design intent, not test results.
Living with it.
Dock mechanisms and stain-jet nozzles remain unproven; first-generation field reports pending.
Unprovenowner-reported arc
FocusJet stain-targeting is flagship innovation with no multi-month owner dataset yet. Self-emptying dock and LiDAR navigation follow established Ecovacs/Yeedi patterns; long-term edge-cleaning reliability unknown.
The independent record is still forming. Failure modes are listed once an outside source reports them.
Refill the clean-water tank and empty the waste tank; clean main and ; check the FocusJet nozzles for blockage.
Inspect the OZMO Roller for wear and trapped hair. The roller self-washes during a run and the station washes and dries it between runs, so it is not a scheduled replacement item.
Rinse main ; replace fine filter if clogged.
Replace self-empty station (~$50); check the station's water tanks and channels for mineral buildup.
Recalibrate room maps if LiDAR performance degrades; clear no-go zones before furniture rearrangement.
$999 to buy, then about $120 a year for the replaceable parts below. Over three years that is roughly $360 past the sticker price. Excludes electricity and any repairs.

LiDAR with AI obstacle avoidance
Position shows where the figure sits across the tracked category, not a quality judgment. Suction in Pascals has no standard test method, and the published figure is a peak-mode claim, so it is comparable only within a brand and generation.
