Yeedi S20 Infinity Ultra

Name: Yeedi S20 Infinity Ultra
Brand: Yeedi

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.

Autonomy Ladder

Yeedi S20 Infinity Ultra finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control
LiDAR with AI obstacle avoidance
Why this level
- LiDAR-based navigation with multi-floor mapping and no-go zones supports Level III conditional autonomy within known environments.
- Vacuum does not operate via teleoperator control.
- Full task execution (room-to-room scheduling, dock returns) is autonomous within the programmed home layout.

Our assessment did not establish an independent source for coverage and navigation, software stability on this machine, so those inputs are left out of the score rather than guessed at, and the rest re-weighted to fill the space. A gap in what we have been able to verify is not evidence against the robot. Where it reaches 30% of the rubric we publish no number at all.

Capability40% of the score69What it does without you.

Task completion16% of the score80

Evidence

Homes & Gardens found it 'did kick a Cheerio or two around and left a trail of sugar on its first pass', needed an extra pass on carpet, and that the Jet Spray stain feature only runs on a zone the operator picks, 'as opposed to doing it on its own'; CGMagazine's tester saw the default two passes per area clear a two-hour-old oil and soy sauce spill almost entirely. It runs a whole home unattended with the station refilling water and washing the roller mid-run, but a person still closes the loop on edge dust and on stains.

Coverage and navigationnot countedno source verified85

Evidence

homesandgardens.com reports the Ultra mapped the tester's space accurately enough that dividing or combining rooms was never needed, with the map retained and editable afterwards, and records no missed regions. matteralpha.com repeats the maker's suction and brush spec paragraph and was excluded as vendor copy on a third-party server.

Edge-case recovery10% of the score50

Evidence

The navigation field states LiDAR with AI obstacle avoidance, so this machine has real pre-contact perception and is not in the bumper-only class where the category ceiling bites. What it does after a stall is entirely unstated: the record documents no recovery behavior, no resume-at-interruption claim and no failure-mode handling, and the only sources are a manufacturer page, a press release and an aggregator, so nothing independent describes the machine getting itself out of anything. Held just below the clean-halt anchor on that silence.

Operating envelope4% of the score75

Evidence

CGMagazine ran it on tile, hardwood and carpet in one home; Homes & Gardens covered 700 to 800 square feet per session across hard floor and carpet with regular mid-run returns to refill water and wash the roller. The one documented degradation is carpet: H&G writes 'it still does not replace the need for a regular vacuum for deep cleaning. This is true more on carpet than on hard flooring'.

Dependability40% of the score64Whether it keeps doing it.

Field failure rate16% of the score70

Evidence

YEEDI's own launch release dates availability to May 20, 2026, so this model carries under three months of field record, and the anchor caps that at 70 while placing a machine with no documented failure at 70 rather than below it. Neither hands-on review reports a fault of any kind.

Software stabilitynot countedno source verified82

Evidence

Just below the ordinary consumer case because the observation window barely exists. The robot runs on the ECOVACS HOME app, a live and actively maintained update channel shared across the parent brand's fleet rather than a single-product stack, and no regression is reported. But the product is ten weeks old, so no regression pattern could yet have formed, and the record carries no changelog, no firmware source and no published support policy. This asserts neither stability nor instability, which on a machine this new is the only honest reading.

Support longevity10% of the score55

Evidence

Scored as commitments. The positives are structural: this is the current top of the Yeedi lineup, Yeedi is an Ecovacs brand, and control runs through ECOVACS HOME rather than a bespoke app, so the cloud and update path are shared with a much larger fleet and do not depend on this SKU selling. Against that, the record names no warranty term, no parts catalog and no repair channel, yeedi's own FAQ states the company does not publish replacement prices for filters and brushes, no cleaning interval is published for the FocusJet nozzles, and the brand's back catalog already contains discontinued docks with proprietary bags.

Ownership burden20% of the score77What it asks of you.

Routine maintenance12% of the score91

Evidence

The annual dust bag is the standout: most self-empty stations run a bag every 30 to 90 days, this one is a yearly swap. There are no pads to wash or replace because the roller self-cleans in the run and the station washes and heat-dries it. The weekly load is what holds it here and it is heavier than the class average: refill the clean tank, empty the waste tank, clean the main and side brushes, and inspect two atomizing nozzles for which yeedi publishes no interval at all, so the owner is checking on a schedule they invented. Filter rinse every three to six months and a mineral-buildup check on the station channels.

Consumables8% of the score57

Evidence

Two real savings, both mechanisms rather than absences: an annual bag at roughly 40 to 60 dollars a year, and no mop pads at any point because the station washes and heat-dries the roller, which is a machine doing the work rather than a missing part. Held to the middle by what is not priced. Yeedi's own FAQ states the company does not publish replacement costs for filters or brushes, and FocusJet sprays cleaning solution onto the floor on every mopping pass, which is a proprietary liquid consumable with no published price, no published consumption rate and no stated third-party alternative.

Reported, not scoredneither measures how well the robot works

Five-year cost$1,700

Upper third for robot vacuums, and the running-cost half of the figure is an estimate rather than a reading, which is worth saying plainly. About 999 dollars at list, plus dust bags at roughly 50 dollars a year, and then filters, brushes, roller replacement and FocusJet cleaning solution, none of which Yeedi prices anywhere on the record. Roughly 140 dollars a year across those is the working assumption here. No subscription: mapping, scheduling and cleaning modes are free in the ECOVACS HOME app.

OWNERSHIP

Living with it.

Dock mechanisms and stain-jet nozzles remain unproven; first-generation field reports pending.

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.

Common questions

What people actually ask.

6 answered

CompatibilityDoes the S20 Infinity Ultra require a 2.4 GHz Wi-Fi network?

Yes. The robot’s Wi-Fi radio operates on 2.4 GHz only and will not pair with 5 GHz-exclusive networks. Dual-band routers (2.4 + 5 GHz) work fine. Single-band 5 GHz networks will prevent setup.

OperationHow often do the FocusJet nozzles need cleaning?

Yeedi publishes no cleaning interval for them. A weekly visual check and clearing of any blockage is a sensible precaution, and in hard-water areas mineral buildup at the nozzle orifice is the thing to watch for. No field data on real-world cadence yet.

OperationCan the S20 Infinity Ultra handle high-pile carpet?

Design and LiDAR optimization target hard floors and low-pile carpet. Owner reports from related Yeedi flagships document suction loss on shag and high-pile. Mop function requires low-pile floors for effectiveness.

OwnershipWhat is the annual cost for dock consumables?

Self-empty dust bags are the main line item, roughly $40 to $60 a year. There are no mop pads to replace: this machine mops with the OZMO Roller 3.0, which self-washes as it runs and is washed with warm water and dried at 145°F by the station between runs, so the roller is a wear part rather than a scheduled consumable. Filters and brushes are the remaining wear items, and Yeedi does not publish replacement prices for them, so a complete annual figure is not established here.

CompatibilityDoes the S20 Infinity Ultra work with Amazon Alexa or Google Home?

Yes. The robot integrates with Alexa and Google Home for voice commands and scene triggering. Pairing happens in the ECOVACS HOME app first, and scheduling, mapping, and cleaning modes remain accessible there independently.

OperationWhat does FocusJet actually do?

It is a pre-spray, not a separate cleaning mode. Yeedi describes dual high-pressure atomizing nozzles that lay a fine mist of cleaning solution onto a stain to dissolve it just ahead of the mop roller, within the same pass. There is no stain-only cycle to schedule and no preset stain zones to configure. Manufacturer claim; independent validation pending.
