High-end vision system with unusual tank tracks. The 360° camera was a genuine departure from LiDAR. Availability was always the constraint, not capability.

45of 100

Limited

DeficientLimitedCapableStrongExemplary

Measured on 8 of the 9 inputs14% not counted

Our assessment did not establish an independent source for software stability on this machine, so that input is 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 score59What it does without you.

Task completion16% of the score70

Evidence

The Ambient's tester reports the 45-minute cycle often does not finish, but 'the Dyson is clever enough to go and charge itself and then resume the job from exactly where it left off', while the 0.33-liter bin is 'full of grey filth' after a single carpet run and is emptied by hand. TechRadar found dock placement alone could make it 'miss out entire areas of your home', the robot refusing to 'venture outside of the lounge' until the dock was moved and the door left fully open.

Coverage and navigation10% of the score63

Evidence

A 360-degree fisheye camera with eight LED sensors running Dyson SLAM produces genuinely systematic coverage, and owner reports put it comparable to LiDAR in well-lit homes, which is a real achievement for a 2018 vision system. The reason it does not reach the anchor is in the same sentence: owners report it struggles in very dark rooms, and a dark room is part of the work area rather than an edge case.

Edge-case recovery10% of the score32

Evidence

The record states Dyson published no obstacle-detection capability and relied on SLAM mapping alone, so there is no material-aware pre-contact perception and the category ceiling applies. The tracked drive helps with carpet transitions but Dyson published no threshold or obstacle height anywhere, so what it clears is undocumented. Owner forums report hair and fiber wrapping the track drive, which the maintenance schedule treats as a weekly manual removal rather than something the machine resolves.

Operating envelope4% of the score72

Evidence

Trusted Reviews' test notes the tank tracks 'climb bigger steps and push through thick-pile carpet and rugs' and that the added LED ring 'makes it possible for the robot to keep going in dark rooms'; TechRadar documents the limit, that it 'needs a bit of space to work in' and 'cramped rooms with a lot of furniture and relatively small gaps to dart through can stop the cleaner from going where it needs to'.

Dependability40% of the score39Whether it keeps doing it.

Field failure rate16% of the score56

Evidence

Eight years since a 2018 launch across EMEA and Asia with four press reviews and active owner forums, and no recall or systemic defect documented, which is a mature record. Four recurring modes are documented, none job-stopping: track drive hair and fiber wrap, lens condensation after every use, track bearing debris, and moisture interference in humid climates. Held at 45 because the 42 anchor requires an orderable part at proportionate cost, and the record states parts and repairs are unavailable through official channels.

Software stabilitynot countedno source verified33

Evidence

The last firmware update is dated 2020 and Dyson ceased support on discontinuation in 2021, so there is no update channel at all, which is the anchor exactly. Six quiet years are not a record of updates that fixed more than they broke; there have been no updates. Under rule 1 a machine with no software left to update earns nothing for having none to break.

Support longevity10% of the score12

Evidence

The textbook case this input exists for. The record states Dyson ceased manufacturing and support to move owners to the 360 Vis Nav, that replacement parts and repairs are unavailable through official channels, that support and parts status is not published, and that secondhand units carry no warranty with parts scarcity making post-repair serviceability risky. There is no first-party channel, no published commitment, and no independent repair path recorded.

Ownership burden20% of the score30What it asks of you.

Routine maintenance12% of the score30

Evidence

Nothing is automated. The bin is emptied and the lens checked for condensation after every single use, the track drive is inspected weekly for hair and fiber with manual removal, the filter is replaced or deep-cleaned monthly with a track bearing check, brushes and a lens calibration check come at three to six months, and the dock has to be dried in humid climates. The per-run cadence on a machine with a small bin is the binding cost.

Consumables8% of the score30

Evidence

The filter is washable and the parts list is short, which would ordinarily be respectable. What decides this input is supply rather than price: the record states parts and repairs are unavailable through official channels, so filters, brush bars, side brushes and the battery must be sourced third-party or secondhand for a machine never sold in the United States. A consumable with no assured channel has an unbounded effective cost, and no credit accrues for the short list.

Reported, not scoredneither measures how well the robot works

Five-year costNot costed

Not purchasable new at any price. Discontinued in 2021, never released in the United States, and sold at £799 at UK launch with no US price ever set. Secondhand units carry no warranty, and the record states parts and repairs are unavailable through official channels, so no honest five-year figure can be quoted: the dominant cost is the risk that any failure is terminal.

Common questions

What people actually ask.

4 answered

OperationWhat made the Dyson 360 Heurist's camera system different from LiDAR competitors?

The Heurist used a 360° fisheye camera with 8 LED sensors and Dyson SLAM technology for navigation, departing from the LiDAR standard established by Roborock and iRobot. Dyson published no “AI obstacle detection” marketing, relying instead on SLAM mapping. Real-world owner reports noted the camera performed comparably to LiDAR in well-lit homes but struggled in very dark rooms.

OperationWhy were the tank tracks significant?

The Heurist used tracked drive units instead of wheels, which help with carpet transitions and give the machine an unusual chassis for its class. Dyson published no threshold or obstacle height for it, in the manual or on the product page, so how large a lip it clears is undocumented. The chassis stands 120 mm (4.7 in) tall, high for a robot vacuum, which keeps it out from under most low furniture.

OperationWhy was the Heurist discontinued?

Dyson has not published a reason. The Heurist sold in a limited set of markets at a premium price and was never released in the United States. Dyson’s next robot vacuum, the 360 Vis Nav, was previewed in May 2023 and reached the US market later still, so it followed the Heurist by several years rather than displacing it at launch.

ComparisonHow does the Heurist compare to the 360 Vis Nav?

Both navigate by vision rather than LiDAR. The Heurist runs on tracked drive units; the Vis Nav uses conventional wheels. Neither mops, and Dyson has not shipped a mopping robot; the Vis Nav also ships without an auto-empty dock or wash station. The Vis Nav is the current-generation product with available support. The Heurist is a historical entry in Dyson’s robot lineup.
