Dyson R2 Nurovi Wash+Dry · Roborock S5 Max

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.

You are buying proven reliability at the cost of feature newness. The S5 Max’s simplicity is its strength; the Qrevo’s complexity adds capability you may not need.

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.

Dynamic homes with frequent furniture rearrangement

Classical LiDAR mapping is less forgiving of layout changes than AI-enhanced systems on newer Qrevos. Map updates require manual intervention.

Owners wanting the latest autonomy features

No camera or AI obstacle recognition; obstacles are found by the bumper rather than avoided in advance. Mopping has no lift and no automation, so the pad is down whenever the module is fitted, including on carpet, and the only zone control is cutting the water flow while the damp pad still passes over. Carpet Boost does raise suction on carpet automatically.

High-pile or shag carpet homes

The mop is a single flat cloth that cannot lift, so on carpeted floors the water tank module has to come off before the run rather than being managed by the robot. On the vacuum side, Carpet Boost raises suction on pile, but suction and brush design are a generation behind later models.
