Dyson R2 Nurovi Wash+Dry · iRobot Roomba Combo j5+

Corner reach is the whole reason for the triangle pads, and the only public demo never pointed them at a corner.

Ninety days between bin emptyings is Dyson’s internal test figure; Dyson itself says real intervals vary with debris, habits and floor type.

The Combo bin gives you both jobs in one pass, but self-emptying is disabled for as long as it is installed, so those runs end with a bin to empty by hand.

The bin sets the mode, which makes the behavior easy to predict, but the robot cannot decide to start a wet run on its own: whichever bin is fitted is what the next scheduled run does.

Buyers who need independent cleaning tests before buying

No hands-on review had been published by 14 Sep 2026. Expert Reviews watched a Dyson event demo handle salt and water spills, but the demo never showed the R2 cleaning a corner.

Homes over 3,000 sq ft expecting one-charge coverage

Dyson publishes a 90-minute maximum run time and a 6.5-hour charge time, but no coverage area per charge and no statement on recharge-and-resume behavior for long runs.

Homes with rugs in rooms that also get mopped

An ultrasonic sensor detects carpet and adjusts suction, but Dyson's product and FAQ pages do not state whether the wash pads lift or detach before the robot crosses a rug.

US shoppers without a Costco membership

Vacuum Wars describes the US launch as a Costco exclusive, and no other US retailer appeared in the sources read. Dyson's own UK store sells it at £749.99.

Owners who want consumable costs known up front

Dyson sells replacement Reuleaux pads, filters, a brush bar with soleplate, and side sweepers, but the UK product page gives no replacement interval or price for any of them.

Mixed-floor homes expecting carpet to be avoided automatically

With the mopping bin fitted, the j5+ has no automatic carpet avoidance. Rugs have to be excluded by the owner, either by drawing No Mop Zones in the app or by running only rooms without carpet. A home that needs that judgment made by the machine rather than by the owner is outside this model's design.

Carpet-primary homes needing intensive mopping

Mopping bin lacks water heating and pad-lift. Design assumes hard floors with light wet cleaning. Deep carpet cleaning and stubborn stains require manual intervention.

Owners seeking zero hands-on involvement with mopping

Bin swaps are required to switch modes. Water tank refill happens manually. Pads are hand-washed weekly. Mopping is not truly autonomous; it is scheduled autonomy.
