Roborock Qrevo CurvX

Multi-floor mapping is where the Qrevo CurvX earns its place in a bigger home: it stores up to four separate floor plans and figures out which one it's on automatically when you carry it upstairs, rather than forcing a fresh mapping run every time. An AdaptiLift chassis lifts to cross thresholds and low obstacles that would otherwise separate one room from the next in an open, sprawling layout.

Suction runs at 22,000Pa, near the top of what Roborock currently ships, useful for the extra square footage and accumulated debris a larger home generates day to day. The Thermo+ dock washes mop pads in 176°F water and handles drying and refilling, so the extra floor area doesn't translate into extra manual maintenance. It's built for a house with more than one level and enough square footage that a robot's map-switching reliability actually matters.
