Our Verdict: Roborock S8 MaxV Ultra
The Bottom Line: For carpet-heavy homes, the S8 MaxV Ultra is the robot to beat: the top carpet score in our database, a strong mapping reputation and the most mature software. Its only real competition is on price, where the JONR X9 Pro gets uncomfortably close on features for under half the cost.

- You need downward active roller scrubbing for thick dried kitchen spills
- 10,000 Pa rated suction and dual rubber rollers for deep carpet
- FlexiArm side brush and extending mop reach right into corners
- Best-in-class app with remote video, voice assistant and Matter
- Dock also refills the robot's water tank and dispenses detergent
- Independently measured 93.9% debris removal on high-pile carpet and 99.8% on hardwood
- You have deep-pile carpets requiring 10,000 Pa suction and dual counter-rotating rubber rollers
- You want complete hands-off autonomy with extending side brush and mop baseboards
- You need Reactive AI 2.0 obstacle avoidance to steer around cables, pet toys, and shoes
- Street price is still around $1,300
- Mop pads spin rather than scrub, so dried stains take multiple passes

- The onboard voice assistant and auto-extending side brush have been reported unreliable in independent testing
- Struggles with fine granular debris (sugar, litter) worked into carpet fibers
- You are on a tight budget under $1,000 and want a better value-to-price ratio

In-Depth Notes & Analysis
DuoRoller Riser Agitation & Carpet Mastery
Roborock's 10,000 Pa motor and counter-rotating DuoRoller Riser system deliver the highest carpet score in our database. The dual textured rubber rollers rotate inward at high speed, dislodging deep debris from carpet fibers without the hair wrap common to bristled brushes.
When crossing onto carpets during a mopping session, the robot automatically lifts its mopping pads by 20 mm and raises the DuoRoller to keep moisture off delicate rug fibers.
FlexiArm Edge Coverage & Sonic Mopping
To overcome the limitation of round robot vacuums in 90-degree corners, the S8 MaxV Ultra features a motorized FlexiArm side brush that extends outward when wall edges or baseboards are detected.
Mopping is powered by VibraRise 3.0 sonic vibration scrubbing at 4,000 vibrations per minute with dual vibration modules, exerting consistent downward pressure on dried kitchen spills.
Reactive AI 2.0 Obstacle Avoidance & App Ecosystem
Reactive AI 2.0 combines structured 3D light with an RGB camera to detect and classify up to 73 distinct object types, including pet waste, slippers, charging cables, and power strips.
The companion app supports multi-floor 3D mapping, customizable no-go zones, and real-time remote video calling with pet-snapshot features. The robot also supports Matter over Wi-Fi for direct Apple Home, Google Home, and Alexa integration.
RockDock Ultra Maintenance & Water Management
The all-in-one RockDock Ultra automates maintenance with 60-day dust bag collection, 140°F (60°C) hot-water mop washing to dissolve greasy stains, and warm-air drying to prevent bacterial growth.
Independent lab tests measured 93.9% debris removal on high-pile carpet and 99.8% on hardwood, confirming flagship-tier pickup across mixed surface layouts.

What Outside Reviewers Say
We cross-check our picks against published expert reviews and, where a page is publicly readable, owner ratings. These sources do not set our score; they test it. Read on 2026-10-18. How we use them.
- T3 (via Yahoo Tech) (2024-07-31): Strong, low-maintenance hybrid vacuum and mop and among the best all-rounders, but the reviewer finds the price hard to justify against competitors. Criticisms: Occasionally stuck on cables; small-obstacle detection trails iRobot's; Mopping better than average but not as thorough as a dedicated hard-floor cleaner; Over 1,000 GBP, dearer than many similarly capable hybrids.
- ProductReview.com.au: owners rate it 4.0 out of 5 from 76 reviews.
