Roborock S8 Pro Ultra - Top 10 Questions and Answers in 2025
BIKMAN TECHAre you considering the Roborock S8 Pro Ultra for your home but have questions about its performance, features, and value? You’re not alone! This high-end robot vacuum and mop has sparked a lot of interest, and we’re here to help you make an informed decision. In this article, we’ll answer the top 10 consumer questions, covering noise levels, carpet navigation, mopping effectiveness, and more, so you can see if this investment is right for your cleaning needs.
1. How Does the Noise Level Compare to Other Models, Especially During Docking?
The Roborock S8 Pro Ultra is designed to keep noise to a reasonable level. On normal settings, it operates at 61dB—about the volume of a lively conversation. When tackling rugs, it ramps up to 69dB. During docking, when the RockDock Ultra empties the dustbin, it peaks at 77dB, similar to a traditional vacuum cleaner. Compared to the S7 MaxV Ultra, which reaches a louder 82.8dB during docking, the S8 Pro Ultra offers a quieter experience, making it a great choice for homes where noise is a concern.
2. Does It Handle Carpet Navigation Well, Like Avoiding Getting Stuck?
Navigating carpets is a breeze for the S8 Pro Ultra, thanks to its LIDAR and Reactive 3D technology, which provide precise mapping. It also includes a Carpet Boost feature that increases suction automatically on carpets. That said, it’s not flawless—it can occasionally get tangled in thick cords or stuck in tight spots like between furniture legs. The good news? The Roborock app lets you set no-go zones to avoid trouble areas. Just clear the floor of small obstacles beforehand, and you’ll enjoy smooth carpet cleaning.
3. How Effective Is the Mopping, Especially Wetness and Stain Removal?
The S8 Pro Ultra shines with its VibraRise 2.0 mopping system, featuring dual vibration points for superior scrubbing. In tests, it scored an impressive 4.64 out of 5, tackling dried-on stains and wet spills with ease. The mop pad lifts automatically when it detects carpets, keeping them dry, and the RockDock Ultra washes and dries the pad after each use to prevent mold. While tiles may feel slightly damp in wipe-only mode, you can tweak wetness levels in the app for a customized clean.
4. Is the Docking Accuracy Reliable, and Does It Charge/Empty Properly?
Docking is a strong suit for the S8 Pro Ultra. It reliably returns to the RockDock Ultra to charge and empty its dustbin, with a 2.5-liter dust bag that lasts weeks. The dock also washes and dries the mop pad, minimizing upkeep. Some users note occasional misalignment, but it’s rare and doesn’t disrupt performance. After cleaning 743 sq ft, it recharges from 19% to full in about an hour, ensuring it’s ready for the next round.
5. How Does It Compare in Price and Features to S7 MaxV Ultra or S8+?
At $1,600, the S8 Pro Ultra sits above the S7 MaxV Ultra ($1,400) and S8+ (around $1,000) in price. But it justifies the cost with upgrades like dual roller brushes, 6,000Pa suction (versus 5,500Pa on the S7), and VibraRise 2.0 mopping. The S7 MaxV Ultra offers a camera for remote viewing, while the S8 Pro Ultra prioritizes privacy with LIDAR navigation. The S8+ skips the self-cleaning dock, making the S8 Pro Ultra the premium pick for hands-off cleaning.

6. Can It Ignore Rugs During Mopping, and How Is the App for Customization?
Yes, the S8 Pro Ultra smartly avoids rugs during mopping. With the app’s Carpet Boost and no-mop zone settings, it lifts the mop pad when it senses carpets, keeping them dry. The Roborock app is a standout—intuitive and packed with options like room-based scheduling, suction adjustments, and 3D mapping to personalize your cleaning. Users love how easy it is to tailor the robot’s performance to their home.
7. What Is the Suction Performance on Different Surfaces, Like Tile Grout?
Boasting 6,000Pa suction, the S8 Pro Ultra excels on hard floors, clearing 97.9% of debris from tile grout and similar surfaces in tests. Its DuoRoller Riser brush doubles down on carpets for a deeper clean. However, tight corners and edges might need a quick manual touch-up, as is common with robot vacuums. Overall, it’s a powerhouse for most flooring types.
8. Are There Privacy Concerns With Cameras and Microphones?
Privacy-minded? You’ll appreciate that the S8 Pro Ultra skips the camera found in models like the S7 MaxV Ultra, relying instead on LIDAR and infrared for navigation. It does have a microphone for voice commands (think Alexa or Google Assistant), but data is encrypted, and you can disable updates in the app for extra control. Reviews suggest privacy risks are low, making it a solid choice for the cautious.
9. How Long Does the Battery Last for Large Areas, Like 3000 Sq Ft?
With a 5200mAh battery, the S8 Pro Ultra runs for up to 180 minutes on quiet mode, covering about 2,500 sq ft per charge. For a 3,000 sq ft home, it might need to recharge mid-session, but it resumes where it left off. The dock also refills the water tank, supporting mopping up to 3,230 sq ft. For big spaces, plan multiple runs or let it recharge and finish the job.
10. Is the Self-Emptying and Self-Cleaning Dock Worth the Premium Price?
The RockDock Ultra is a game-changer, handling dustbin emptying, mop washing, drying, and water refilling with minimal effort—just empty the dirty water tank and swap the dust bag every few weeks. Priced at $1,600, it’s a splurge, but the hands-free convenience and mold-preventing drying feature make it a worthy investment for busy folks or anyone craving automation.
