Clash of the Titans: An Overview
The world of robotic cleaning has evolved rapidly, and these three models represent the pinnacle of current technology. Each brings a unique approach to automated floor care. The 🟨 DEEBOT X2 OMNI stands out with its innovative square shape, designed for superior edge cleaning. The 🟦 S8 MaxV Ultra pushes the boundaries with its dual roller brushes and an advanced mopping system that includes a side brush for corners. Meanwhile, the 🟩 Roomba Combo j9+ leverages iRobot's decades of experience with a unique, fully retractable mop and a system that automatically refills its own cleaning solution.
Key Feature Comparison
When looking at flagship features, all three models boast impressive capabilities. The 🟨 X2 OMNI features a powerful 8,000 Pa suction, hot water mop washing, and an intelligent mop lifting system. It's a true all-in-one that aims for minimal human intervention.
The 🟦 S8 MaxV Ultra counters with an even stronger 10,000 Pa suction power and its DuoRoller Riser™ Brush system to prevent hair tangles. Its standout feature is the FlexiArm Design™ side brush and an extra side mop that extends to clean edges and corners that others might miss, a common pain point for robot mops.
The 🟩 Combo j9+ introduces the D.R.I. (Dry Rug Intelligence) system. Its Auto-Retract Mopping System lifts the mopping pad to the top of the robot, completely away from carpets to guarantee they stay dry. It also features a Dirt Detective function that automatically prioritizes the dirtiest rooms and adjusts cleaning settings accordingly.
Design and Build Quality
The design philosophy of each robot is distinct. The 🟨 X2 OMNI adopts a slim, square profile. This 'squircle' shape is not just for looks; it's engineered to get deeper into corners than its round counterparts. Its compact OMNI station is also designed to fit more seamlessly into modern homes.
The 🟦 S8 MaxV Ultra maintains a more traditional circular design but is packed with visible tech. Its RockDock® Ultra is a comprehensive station that handles everything from washing the mop with heated water, to drying it with warm air, to emptying the dustbin and refilling the water tank.
The 🟩 Combo j9+ features a premium, textured finish and a more utilitarian design. Its Clean Base® Auto-Fill Dock is unique because it not only empties debris for up to 60 days but also refills the robot's water or cleaning solution tank for up to 30 days, a feature aimed at maximum autonomy.
Vacuuming and Mopping Performance 🧹💧
Vacuuming Power
In terms of raw suction, the 🟦 S8 MaxV Ultra leads with a staggering 10,000 Pa. This is followed closely by the 🟨 X2 OMNI at 8,000 Pa. The 🟩 Combo j9+ uses a 4-Stage Cleaning System with powerful suction and dual rubber brushes, though iRobot doesn't typically publish Pa ratings, focusing instead on the effectiveness of the entire cleaning system. All three are exceptional at picking up debris, from fine dust to pet hair, on both hard floors and carpets.
Mopping Innovation
Mopping is where these robots truly diverge. The 🟨 X2 OMNI uses its OZMO Turbo 2.0 rotating mopping system, where two pads spin under pressure to scrub floors. It also uses hot water in its station to wash the mops, which helps break down grease and grime more effectively.
The 🟦 S8 MaxV Ultra employs the VibraRise® 2.0 Mopping System, which sonically scrubs floors up to 3,000 times per minute. Its unique extending side mop gives it an edge in reaching tricky spots along baseboards.
The 🟩 Combo j9+ focuses on preventing cross-contamination. Its mop pad retracts to the top of the robot when carpet is detected, ensuring no dampness touches your rugs. It's the only one of the three that can use a pre-mixed cleaning solution that its dock automatically replenishes.
Navigation and Obstacle Avoidance 🗺️
Smart navigation is crucial for an effective clean. The 🟨 X2 OMNI uses a combination of Dual-Laser LiDAR embedded within the chassis, which contributes to its lower profile, and an AINA deep learning model for agile movement and obstacle avoidance.
The 🟦 S8 MaxV Ultra is equipped with Reactive AI 2.0 Obstacle Avoidance, which uses an RGB camera and 3D structured light to recognize and avoid a wide range of household objects, from shoes to pet waste. Its LiDAR navigation creates precise maps for efficient cleaning paths.
The 🟩 Combo j9+ relies on its advanced vSLAM® navigation and PrecisionVision Navigation system. It uses a camera to identify and avoid obstacles in real time. iRobot backs this with its P.O.O.P. (Pet Owner Official Promise), guaranteeing it will avoid pet waste.
Docking Station Capabilities 🔋
The "OMNI" and "Ultra" names signify that these are more than just robots; they are complete cleaning systems. The stations are large but incredibly functional.
🟨 X2 OMNI Station: Auto-empties the dustbin, washes the mop pads with 55°C (131°F) hot water, dries the mops with hot air, and refills the robot's water tank.
🟦 RockDock® Ultra: Auto-empties dust, washes the mop with 60°C (140°F) hot water, dries with warm air, refills the water tank, and has an optional dock that can be plumbed into your home's water lines for true automation.
🟩 Clean Base® Auto-Fill Dock: Auto-empties debris into an AllergenSeal bag, and uniquely, auto-fills the robot's tank with either water or a cleaning solution from a large reservoir within the dock.
