Dreame Bot W10 · Dyson R3 Nurovi Spot+Scrub UV

The dock washes and hot-air dries the pads without help, but the pads themselves never lift: any carpet inside a mopping zone has to be excluded in the app or the pads taken off by hand.

LiDAR mapping is solid and enables multi-floor handoff, but 4,000 Pa suction is below current flagships. Capability ceiling is ceiling, not floor, for pet homes.

A stain it can see gets washed until it clears; a stain it cannot classify gets the ordinary pass, and Dyson’s own footnote concedes results vary by stain type.

Hot-water roller washing in the dock removes the grimiest chore, at the cost of a dock that heats water to 158°F beside the floor it serves.

Homes with rugs or carpet inside the mopped rooms

The two mop pads are fixed to the underside and do not lift. Dreame's guidance is not to run them over carpet, so a mopping pass through a room with a rug in it means pulling the pads off by hand first or excluding the area in the app.

Pet-hair-heavy carpet homes

LiDAR handles carpet detection well, but suction (4,000 Pa) is mid-range for 2021. Heavy pet shedding results in frequent brush tangles; LiDAR does not compensate for lower suction on high-pile.

Apartment dwellers with space constraints

Dock is large (23" × 15" footprint) and requires a drying rack nearby. Not suitable for compact apartments or homes where dock placement is limited.

High-pile or long-fiber carpet primary surfaces

4,000 Pa suction is adequate for low-pile and hard floors. Owner reports show visible dirt retention on shag or high-pile; LiDAR excels at mapping but suction underperforms the category baseline for 2024+.

Buyers who need independently tested suction and stain detection

The 30,000 Pa rating and the near-200-substance recognition are Dyson claims. Dyson's own footnote says results may vary by stain type and severity, and no third-party test exists yet.

Homes that are mostly carpet or high-pile rugs

Dyson has not published how the wet roller behaves on carpet, whether it lifts, or a carpet cleaning figure for the R3. The stain loop is described only for hard floors.

Shoppers comparing runtime, size and noise before buying

No robot dimensions, weight, battery capacity, runtime or noise rating appear in any launch material or Dyson page reviewed for this record.

Buyers in the UK or Australia wanting one this year

Vacuum Wars reports the UK and Australian launch following in early 2027, and Digital Reviews Network says Australian pricing has not been announced.

Buyers who need a documented navigation sensor suite

Launch coverage names a camera, green illumination and UV light for stain detection, but Dyson has not described how the R3 maps rooms or which sensors it navigates by.
