Dyson's first serious robot vacuum brings genuinely clever stain detection and bagless convenience, but a bulky dock and immature software hold it back from the Chinese flagships it's priced against.
The stain detection is not marketing theater -- we deliberately smeared dried coffee and pasta sauce on tile, and the green LED picked up both on its first pass, then circled back to re-scrub until the sensor gave the all-clear. That capability is genuinely unique. The bagless cyclone emptying is vintage Dyson and saves real money over time. Where the cracks show is in the software and dock reliability -- the MyDyson app is frustratingly bare-bones compared to what Roborock and Dreame ship, the dock is enormous, and we experienced the re-docking alignment issue that other reviewers have flagged. If stain detection and zero consumable costs matter most to you, nothing else does what the Spot+Scrub does. For everything else, the competition is ahead.
Key Specs at a Glance
Pros & Cons
What We Like
- + AI stain detection with green LED genuinely finds and re-scrubs dried-on stains other robots roll right over
- + Bagless cyclone auto-empty eliminates ongoing dust bag costs — a Dyson exclusive in this category
- + Hot-water mopping at 60C with self-cleaning roller is more hygienic than most pad-based competitors
- + Recognizes nearly 200 object types for reliable obstacle avoidance around cables, shoes, and pet toys
- + 200-minute battery handles large homes in a single charge without needing to return to dock mid-clean
What Could Be Better
- − Dock footprint is almost comically large — plan to sacrifice a significant chunk of floor space
- − MyDyson app feels basic next to Roborock or Dreame apps, with dock controls buried in menus
- − Occasional dock re-entry failures and self-empty reliability issues reported across multiple reviews
- − At $1,099, the price-to-performance ratio trails Chinese flagships that mop more consistently for less
