iRobot Roomba Plus 405 Combo: The All-In-One Robot Vacuum and Mop System That Does It All

The iRobot Roomba Plus 405 Combo Robot (model G185) represents the intersection of iRobot's 30+ years of robotic cleaning expertise and its most advanced autonomous maintenance technology to date. Paired with the AutoWash Dock, this system doesn't just vacuum and mop your floors — it manages, washes, dries, and maintains its own cleaning equipment so that every session starts fresh and every surface is genuinely clean. For anyone who has ever wondered whether a robot vacuum can truly replace manual cleaning routines, the Roomba Plus 405 Combo with AutoWash Dock is the most compelling answer yet.

AutoWash Dock: The Self-Maintaining Home Base

The AutoWash Dock is the technological centerpiece of this system, and what separates it from standard robot vacuum docks in a meaningful way. It performs four critical functions automatically: it self-empties the robot's debris bin into a sealed bag that holds up to 75 days of dirt; it washes the DualClean mop pads during and after cleaning runs to prevent dragging dirty water across your floors; it dries the mop pads after washing so they're fresh and ready for the next session; and it performs a self-cleaning cycle that clears debris buildup from within the dock itself. This level of autonomous maintenance means the system genuinely manages itself between cleaning sessions, requiring only occasional bag replacements and minimal oversight.

DualClean Mop Pads with SmartScrub Technology

Mopping is where many robot vacuum-mop combos fall short, delivering only a light damp-mop pass that fails to address dried spills or embedded grime. The Roomba Plus 405 Combo takes a fundamentally different approach with its spinning DualClean Mop Pads, which apply active downward pressure while rotating to scrub surfaces rather than simply drag a wet cloth across them. Paired with SmartScrub mode, the robot performs repeated passes over specific areas for 2x deeper scrubbing compared to standard vacuum-and-mop mode — particularly effective on stubborn messes like dried coffee, food residue, and pet-related grime on kitchen and bathroom floors. The mop pads work with water or compatible cleaning solutions for enhanced results.

Automatic Carpet Detection and Pad Lift

A critical limitation of many robot mop combos is the risk of dragging wet mop pads over carpets — potentially causing moisture damage or simply spreading dirty water. The Roomba Plus 405 solves this elegantly with automatic carpet detection: intuitive sensors identify when the robot is approaching carpet and automatically lift the mop pads to prevent contact. This means you can set the robot to combo-clean mode and trust it to mop hard floors while protecting your carpets without any manual zone configuration required.

70x More Power-Lifting Suction

Compared to the Roomba 600 series, the Plus 405 delivers 70 times more power-lifting suction — a dramatic leap in dirt extraction capability. This is backed by a multi-surface rubber brush paired with an edge-sweeping brush, ensuring that fine dust, crumbs, pet hair, and debris hiding along baseboards and in corners are captured comprehensively. The result is a vacuum performance that competes credibly with full-size upright vacuums in terms of the dirt it lifts from both carpet pile and hard floor surfaces.

ClearView LiDAR Navigation

The Roomba Plus 405 uses ClearView LiDAR technology to map your home rapidly and accurately. Lidar-based mapping enables the robot to navigate in neat, efficient rows rather than random bump-and-go patterns, maximizing floor coverage while minimizing redundant passes. The system works effectively even in complete darkness — useful for scheduled overnight cleaning runs. Specialized sensors steer the robot around furniture, pet toys, cables, and other floor obstacles, while stair-detection sensors prevent falls. Clean Zones and Keep Out Zones give you precise spatial control over where the robot cleans and what it avoids.

Fully Customizable Cleaning with the Roomba Home App

The redesigned Roomba Home App offers an intuitive interface built around how people actually clean. You can set custom cleaning routines for specific rooms on specific days and times, direct the robot to clean targeted zones on demand, review filter health and maintenance reminders, and even identify which rooms in your home need the most attention based on historical cleaning data. Four cleaning modes — vacuum only, mop only, combo clean, and vacuum-first-then-mop — give you complete control over the type of clean delivered to each surface. Voice assistant compatibility with Alexa, Siri, and Google Assistant adds a hands-free control layer.

Three-Way Control for Maximum Convenience

Control the Roomba Plus 405 in whichever way fits your lifestyle: use voice commands through Alexa, Siri, or Google Assistant; navigate the user-friendly Roomba Home App for full scheduling and zone management; or simply press the physical buttons on the robot itself for quick, one-touch starts. The flexibility of three control methods ensures the system works seamlessly into any household routine.

The Ideal Solution for Effortlessly Clean Floors

The iRobot Roomba Plus 405 Combo with AutoWash Dock is the flagship expression of truly autonomous floor care. From its self-washing mop pads and 75-day auto-empty bin to its LiDAR mapping and SmartScrub mopping, every component is engineered to reduce your involvement while increasing the quality and consistency of your clean. For households that want genuinely spotless floors without the manual effort, the Roomba Plus 405 Combo is in a class of its own.
