iRobot Roomba Plus 405 (G181) Combo Robot Vacuum & Mop with AutoWash Dock - Amazon Exclusive, Dual Spinning Mop Pads, Self-Empties for 75 Days, Intense Suction, Pad Washing & Drying, Pad-Lift, LiDAR
The iRobot Roomba Combo j9+ (model 405 G181) is a multifunctional robotic cleaning system that integrates vacuuming and mopping capabilities. It includes an AutoWash Dock, a LiDAR-based navigation system, dual spinning mop pads, and self-emptying and self-cleaning features. Designed for use on various floor types, this model is part of the Amazon Exclusive line and comes with several advanced automation features tailored to modern households.
Design and Construction
The device features a round body with a low-profile design, enabling it to navigate under furniture and into tight spaces. It has a sleek exterior with a matte finish and houses sensors, wheels, brushes, and mop pads in a compact form. The AutoWash Dock complements the main unit with integrated containers for water and dust, a drying station, and a charging port. Dual mop pads are positioned at the rear underside, while the multi-surface rubber brush and edge-sweeping brush are located underneath the front.
Navigation System
The Roomba Combo j9+ utilizes ClearView LiDAR technology for mapping and navigation. The system scans the surrounding environment to build a digital layout of the home, identifying walls, furniture, and obstacles. This mapping enables the robot to plan efficient routes, ensuring thorough coverage. It includes fall sensors that prevent the device from descending stairs or ledges. The navigation software adjusts the cleaning path in real time based on object detection and floor type.
Cleaning Modes
This model supports multiple cleaning modes: vacuum only, mop only, combination clean, and vacuum-then-mop. Each mode can be selected through the Roomba Home App. In combination cleaning, the robot uses suction and mopping simultaneously, while the vacuum-then-mop mode performs dry cleaning first, followed by wet cleaning. Users can also configure specific rooms or zones for each type of cleaning session. The mop pads automatically lift when the device detects carpeted areas, preventing moisture from contacting sensitive surfaces.
Vacuuming Features
The vacuuming system includes 70x more suction power compared to the Roomba 600 series. A high-efficiency motor generates intense suction to collect debris such as dust, dirt, crumbs, and pet hair. The multi-surface rubber brush adapts to both hard floors and carpets, while the edge-sweeping brush reaches into corners and along baseboards. There are four suction levels available, and the system automatically adjusts based on the detected floor type.
Mopping System
The mopping function includes DualClean spinning mop pads, which rotate to scrub the floor surface. The SmartScrub feature applies downward pressure to improve stain removal. Cleaning fluid or water can be used in the built-in reservoir, and users can configure the mop settings within the app. Mop pads are washable and reusable. During mopping runs, the system can increase scrubbing intensity for sticky or dried-on messes, such as coffee spills or grime.
AutoWash Dock
The AutoWash Dock is designed to handle various maintenance tasks. It empties the dustbin into a disposable bag, which holds up to 75 days’ worth of debris, depending on usage frequency. It also washes the mop pads, refreshes them with clean water, and dries them to prevent odor or mildew. The dock contains compartments for clean water, dirty water, and the vacuumed debris. It reduces the need for manual cleaning or pad handling after each session.
Roomba Home App
The dedicated app allows users to control the device remotely. Features include real-time mapping, scheduling, zone cleaning, performance analytics, and equipment health monitoring. The interface displays an overview of the cleaning session, including estimated duration, completed areas, and filter or pad status. Users can customize cleaning routines, create “no-go” zones, and define preferences for different rooms, such as higher suction in living rooms or pad lifting on bedroom carpets.
Sensors and Automation
The robot is equipped with a combination of proximity sensors, cliff sensors, and floor detectors. These components work together to guide the device through furniture-filled rooms while avoiding falls and collisions. The mop lift sensor ensures that carpets remain dry, and surface sensors allow the vacuum to optimize suction automatically. The robot can also identify high-traffic areas and initiate repeat passes for improved cleaning results.
Battery Life and Charging
The device operates on a rechargeable lithium-ion battery. Depending on the cleaning mode and settings, a single charge can support approximately 120 minutes of runtime. When the battery is low, the robot automatically returns to the dock for charging. Once recharged, it resumes the cleaning task from where it left off. The charging process and battery health can be monitored through the app.
Maintenance and Consumables
Routine maintenance involves replacing the dustbin bag, rinsing the mop pads, checking the filter, and refilling the clean water tank. The robot notifies users when maintenance is needed. Most parts are modular and easily detachable for cleaning or replacement. The mop pads are reusable and machine-washable. The filter and disposable bag need replacement after a certain number of uses, which can be tracked through the app.
Floor Compatibility
The iRobot Roomba Combo j9+ is suitable for various surfaces, including tile, hardwood, laminate, vinyl, and low- to medium-pile carpets. The smart sensing system adapts suction and pad movement based on the floor detected. It transitions smoothly between different surface types and avoids dragging mop pads across carpeted areas. The vacuum function is optimized for deep debris removal, while the mopping function handles light to moderate surface stains.
Noise and Operation
During operation, the device emits a moderate level of noise, particularly when in maximum suction mode or during the pad cleaning cycle. The dock generates additional noise during debris suction and mop pad washing. The volume level varies depending on the floor type, suction level, and cleaning mode. Quiet operation can be scheduled during preferred time slots using the app.
Setup Process
Initial setup includes installing the dock, filling the water reservoir, attaching the mop pads, and connecting the device to the home Wi-Fi network via the app. The first mapping run allows the robot to scan and store a floor plan. Users can then label rooms, set cleaning zones, and schedule sessions. Firmware updates are delivered automatically through the app when the robot is connected to Wi-Fi.
Smart Home Integration
The Roomba Combo j9+ supports integration with smart home platforms such as Amazon Alexa and Google Assistant. Voice commands can initiate or stop cleaning, target specific rooms, or check on cleaning status. The robot can be included in routines, such as cleaning the kitchen after breakfast or running a full-house clean before returning from work.
