Dyson R3 Nurovi Spot+Scrub UV · Ecovacs Deebot T20 Omni

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.

Hot-water wash adds cleaning capability but not autonomy because the dock cycle is 2-3 hours; autonomous operation remains scheduled, not on-demand.

TrueDetect 3D replaces the X1 Omni’s camera, which takes in-home imaging off the machine but also removes camera-based object recognition; obstacle detection is laser-only.

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.

High-pile or dense Berber carpet homes

Mop lifting is marginal; owner reports show reduced effectiveness on high-pile surfaces. Brush entanglement remains an issue.

Owners unable to accommodate periodic app-based scheduling

Hot-water wash cycle is 2-3 hours; scheduling conflicts with typical household routines unless owner programs into a low-traffic window.

Homes with sparse Wi-Fi 2.4 GHz coverage

Both robot and dock require stable 2.4 GHz connectivity. 5 GHz-only networks are not supported.

Compact apartments under 1,000 sqft with limited outlet proximity

The station needs a 120V outlet and a clear floor position 17.6 x 16.9 inches with 22.8 inches of height above it. No plumbing or drain is involved, but in a studio that is a permanent piece of floor furniture.
