Clash of the Cleaning Titans: Roomba s9+ vs. Roborock S8 Pro Ultra

 

Robot vacuums have evolved from simple floor sweepers to sophisticated cleaning machines. Today, we're dissecting two top contenders: the iRobot Roomba s9+ and the Roborock S8 Pro Ultra. This isn't just a surface-level comparison; we're diving deep into the features, performance, and nuances to help you make the best choice for your home.

Round 1: Design and Aesthetics – Form and Function

    Roomba s9+: The distinctive D-shape of the s9+ isn't just a stylistic choice; it's designed to improve edge and corner cleaning. This allows the robot to get closer to walls and into corners than traditional round robots. The Clean Base, while functional, is fairly standard in its design, focusing on self-emptying.

    Roborock S8 Pro Ultra: Roborock has opted for a more futuristic aesthetic with the S8 Pro Ultra. However, the real story is its massive dock, the RockDock Ultra. This isn't just a charging station; it's a multi-functional cleaning center. It handles self-emptying, mop washing, and mop drying, significantly reducing user intervention.

Round 2: Cleaning Performance – Where the Rubber Meets the… Floor

    Roomba s9+: The s9+ is a powerhouse when it comes to suction. Its high-efficiency motor and specialized brush system are designed for maximum dirt and debris pickup, especially on carpets. The corner brush and D-shape contribute to effective edge cleaning. However, it's worth noting that the s9+ primarily focuses on dry vacuuming.

    Roborock S8 Pro Ultra: The S8 Pro Ultra offers impressive suction, but its standout feature is the VibraRise mopping system. This sonic mopping technology scrubs floors at a high frequency, removing dried-on stains and grime more effectively than traditional drag-mop systems. The ability to lift the mop pad when encountering carpets is a significant advantage, preventing wet carpets. The S8 Pro Ultra truly is a two-in-one cleaning solution.

Round 3: Navigation and Mapping – The Brains of the Operation

    Roomba s9+: The s9+ utilizes vSLAM (Visual Simultaneous Localization and Mapping) navigation. This system uses a camera to create a map of your home and navigate. While effective, vSLAM can be less reliable in low-light conditions and may struggle with highly reflective surfaces. It also lacks the precision of LiDAR.

 

 

    Roborock S8 Pro Ultra: The S8 Pro Ultra employs PreciSense LiDAR navigation, which uses lasers to create a highly accurate 3D map of your home. This allows for precise navigation, efficient cleaning paths, and features like No-Go Zones, No-Mop Zones (crucial for protecting carpets during mopping), and selective room cleaning. The Reactive AI obstacle avoidance also helps it navigate around everyday clutter like shoes and toys.

Round 4: Features and Functionality – The Details That Matter

Feature	Roomba s9+	Roborock S8 Pro Ultra
Self-Emptying	Yes (Clean Base)	Yes (RockDock Ultra with self-emptying, mop washing, and mop drying)
Obstacle Avoidance	Basic camera-based avoidance	Reactive AI obstacle avoidance (identifies and avoids common household items)
Mopping	No	Yes (VibraRise sonic mopping with automatic mop lifting on carpets)
Mapping	vSLAM	PreciSense LiDAR with 3D mapping and multi-floor mapping
App Control	iRobot Home app (scheduling, cleaning history, custom cleaning preferences)	Roborock app (detailed mapping, custom cleaning modes, No-Go Zones, No-Mop Zones, selective room cleaning, remote viewing with camera on some models)
Battery Life	Up to 120 minutes	Up to 180 minutes
Noise Level	Generally louder due to powerful suction	Generally quieter, especially during mopping
Dustbin Capacity	Relatively small on the robot itself, larger capacity in the Clean Base	Larger dustbin on the robot, large capacity in the RockDock Ultra
Maintenance	Emptying Clean Base, cleaning brushes, replacing filters	Emptying RockDock Ultra, cleaning brushes, replacing filters, cleaning the mop and dock components
Special Features	AllergenLock bags in Clean Base	VibraRise mopping, automatic mop lifting, self-washing and drying mop, Reactive AI obstacle avoidance

Round 5: Price and Value – The Bottom Line

The Roomba s9+ and the Roborock S8 Pro Ultra are both premium-priced robot vacuums. However, the Roborock S8 Pro Ultra typically comes with a higher price tag due to its more advanced features, particularly the mopping system and the multi-functional dock.

 

 

The Verdict: Choosing Your Cleaning Champion

    Choose the Roomba s9+ if: Your primary concern is powerful vacuuming, especially on carpets, and you don't need mopping capabilities. You prioritize a more compact dock and are willing to accept less advanced obstacle avoidance.

    Choose the Roborock S8 Pro Ultra if: You want a truly versatile cleaning solution that can both vacuum and mop effectively. You value advanced navigation, obstacle avoidance, and the convenience of a self-cleaning and self-drying mopping system. You are willing to invest in a higher-priced device for these advanced features.

Beyond the Specs: Real-World Considerations

    Pet Owners: Both robots can handle pet hair, but the s9+'s powerful suction might be slightly better for very heavy shedding. However, the Roborock's self-washing mop is a huge advantage for cleaning up pet messes on hard floors.

    Homes with Mixed Flooring: The Roborock S8 Pro Ultra is the clear winner for homes with a mix of carpets and hard floors due to its mopping capabilities and automatic mop lifting.

    Busy Lifestyles: The Roborock's self-cleaning and self-drying dock significantly reduces maintenance, making it a better choice for busy individuals.

 

By considering these factors and the detailed information provided, you can confidently choose the robot vacuum that best suits your needs and transforms your cleaning routine.
