Dyson R3 Nurovi Spot+Scrub UV Review 2026: The Robot That Checks Its Own Stain Work With UV

Verdict up front: The Dyson R3 Nurovi Spot+Scrub UV is a $1,199.99 wet-and-dry robot vacuum built around one idea no rival in our coverage offers: it uses UV light and AI vision to find dried-on stains you cannot see, scrubs them with a heated-water roller, then checks the spot again before moving on. Dyson’s US store lists it in stock now, and it launched in Singapore on November 5, 2026 at S$1,699. The catch is price and fine print — the headline clean depends on Dyson’s own test parameters, and the probiotic cleaning solution for the dock is sold separately. Based on specs, pricing, and Dyson’s published details; we have not hands-on tested it.

What is the Dyson R3 Nurovi Spot+Scrub UV?

The R3 is the flagship of Dyson’s three-model Nurovi robot lineup, above the vacuum-only R1 and the Costco-only R2 Wash+Dry. An HD camera, UV illumination, and green laser-like light scan the floor while it cleans; Dyson says the system identifies nearly 200 types of spills, stains, and household objects and adapts its passes to each one. High-speed LiDAR maps rooms and labels them in the MyDyson app. Where roller-mop rivals we have covered, like the Narwal Flow 2 and the eufy Omni S2 Pro, mop on a schedule and move on, the R3’s pitch is verification: clean, re-check under UV, and clean again if the stain is still there.

What Dyson’s own page doesn’t make obvious

Three details from Dyson’s own product page deserve a plainer reading. First, the dock’s “hygienic finish” comes from Dyson’s 02 Probiotic hard floor cleaning solution, which the page lists as sold separately — it is not in the box. Second, the UV verification claim carries Dyson’s footnote that “AI verification is within the defined parameter” and results vary by stain type, and the page’s own walkthrough says the robot checks the floor between passes rather than guaranteeing removal. Third, the dock’s 131°F hot-air drying cycle takes three hours, so the roller is out of action for a while after a deep clean. None of this kills the concept, but buyers comparing it with the Roborock Saros 10R should price the whole system, solution included, not just the robot.

Who it’s for

Hard-floor homes with pets, kids, and a steady supply of dried-on kitchen and entryway stains, where a normal robot mop’s single pass leaves residue behind. If your floors are mostly carpet, or your messes are just dust and hair, the cheaper dry-only robots in Dyson’s own lineup — or any mid-range vacuum — make more sense.

Pros and cons

Pros: UV-verified stain cleaning no rival currently matches; 30,000 Pa suction; bagless dock holds up to 100 days of debris, so no bag subscription; heated-water self-cleaning roller that extends to the skirting board; on-device AI processing, with Dyson stating images are not stored on the robot.

Cons: $1,199.99 flagship pricing; probiotic cleaning solution sold separately; stain claims rest on Dyson’s own test parameters, with no independent lab results yet; three-hour roller drying cycle at the dock.

Frequently asked questions

How much does the Dyson R3 Nurovi Spot+Scrub UV cost? $1,199.99 in the US from Dyson’s own store, and S$1,699 in Singapore, where it went on sale on November 5, 2026.

Does it really remove stains you can’t see? Dyson says its AI scanner uses UV light to reveal hidden stains and re-cleans until its check passes, but its own footnote limits the claim to a “defined parameter” — treat it as targeted extra passes, not a guarantee.

Does the dock need bags? No. The cyclonic dock is bagless and stores up to 100 days of dry debris, though Dyson’s probiotic cleaning solution is an extra purchase.

How long does it run? Up to 200 minutes per charge per Dyson’s spec sheet, with a 3-hour recharge.
