Carpet needs a brush that agitates fibers and a robot that won’t drag a wet mop across your rugs. We don’t invent deep-clean rankings — we stick to maker claims and honest gaps.

How I chose
Criteria: brush type, maker suction claims (Pa only when the maker publishes them), threshold climbing notes if listed, and mop-lift or no-mop behavior on rugs. Sources: iRobot and Roborock product pages via our live reviews. No lab carpet scores.
Who this is for
Homes with wall-to-wall or large area rugs who still want a robot for daily debris — especially mixed hard-floor + carpet layouts.
What matters
- Brush type that can agitate carpet (rubber rollers vs flimsy bristles)
- Maker suction claims — only as labeled (e.g. Roborock 4200 Pa Max+ on their page)
- Threshold / climb limits if the maker lists them
- Mop lift, detach, or no-mop zones so wet pads stay off rugs
- Edge cleaning if you care about baseboards
First looks on this site
Roomba Combo j9+

Dual rubber brushes, Auto-Retract mop, Clean Base (maker). Full review.
iRobot’s Auto-Retract mop lifts to the top of the robot on carpet so rugs stay dry (maker). Dual rubber brushes and power-lifting suction claims are aimed at mixed floors. Read: Roomba Combo j9+ review.
Roborock Q7 Max

Rubber brush, LiDAR mapping, vacuum+mop (maker). Full review.
Roborock lists 4200 Pa in Max+ (maker internal test, IEC 62885-2) and simultaneous vacuum+mop. How the mop behaves on carpet is not spelled out as an auto-lift on the product page we used — plan no-mop zones or lift the pad yourself unless the app/manual says otherwise.

Who should skip
Skip combo mops that can’t lift or detach if you have thick rugs and hate babysitting no-mop zones. Skip any pick if you need a published carpet deep-clean score from us — we don’t run that test.
FAQ
Will high Pa clean high-pile? Maker Pa is a peak claim, not a pile-height guarantee. Check brush design and the maker’s carpet notes.
Do I need obstacle avoidance on carpet? It helps with cords and toys sitting on rugs; still declutter when you can.
Bottom line
Prefer rubber brushes and a clear mop-lift story for carpet. Confirm live price and stock before you buy.
