Roomba Plus 405 Review: Vacuum, Mop & AutoWash Dock

Introduction

The Roomba Plus 405 Combo is a robot vacuum and mop combo designed to handle everyday dirt, spilled coffee, pet hair and scuffed floors with minimal babysitting. It pairs a more powerful suction system with spinning mop pads and targeted scrubbing, then returns to an AutoWash dock that handles emptying and pad care.

This model is aimed at busy households that want hands-off floor care across mixed surfaces — especially homes with pets and frequent small messes. Quick verdict: If you want a largely self-maintaining robot that vacuums and aggressively mops, the Roomba Plus 405 Combo is a practical, feature-rich choice.

What’s in the Box

• 1 Roomba Plus 405 Combo robot
• 1 AutoWash dock
• (Other accessories and consumables: Not specified)

Design & Build

The Roomba Plus 405 Combo follows a familiar circular robot silhouette but adds a low-profile mop assembly beneath the chassis. The main outer shell appears to be hard plastic with a glossy top and tactile buttons for one-touch control; specific materials and finish details are not specified. Build quality looks utilitarian and focused on ease of cleaning — the mop pads and brushes are removable, and the dock houses mechanical and fluid-handling components.

Size and weight: exact dimensions and weight are not listed, so you should assume standard mid-size robot proportions. The low profile helps it slide under most sofas and cabinets, while the rounded edges and modest height reduce the risk of getting stuck. Ergonomically, the controls are simple: app control plus direct buttons on the unit. The AutoWash dock is a separate, larger unit that requires dedicated floor space near an outlet.

Key Features

Strong suction and multi-surface cleaning

Benefit: The Roomba Plus 405 Combo emphasizes stronger suction for lifting fine debris and pet hair from carpets and hard floors. The manufacturer compares its suction to older Roomba 600-series models, claiming a substantial increase, which translates to fewer passes to remove embedded dirt. This helps when you need one-pass pickup of crumbs or daily pet shedding.

Where it helps: Kitchens after meals, entryways with tracked-in grit, and homes with shedding pets that need reliable pickup without constant manual vacuuming. (source: listing, checked 2025)

Advanced mopping — DualClean Mop Pads + SmartScrub

Benefit: DualClean mop pads spin and apply downward pressure while SmartScrub increases scrubbing action, designed to tackle dried-on spots like coffee rings and tracked mud. The pads can be used with water or a cleaning solution, providing flexibility depending on floor type and stain severity.

Where it helps: Hard floors with sticky spills, around pet bowls, or in high-traffic areas where grime builds up. The extra scrubbing is useful when a surface needs more than a wipe rather than a full wet mop session. The manufacturer claims the system provides “2x deeper scrubbing” compared to its standard vacuum-and-mop mode (source: listing, checked 2025).

ClearView LiDAR mapping and navigation

Benefit: A LiDAR-based mapping system scans the home to create an efficient cleaning path, reducing redundant passes and improving coverage. This kind of mapping enables consistent room-by-room cleaning and smoother obstacle avoidance.

Where it helps: Homes with multiple rooms, furniture layouts that would confuse simpler random-drive robots, and households where you want predictable results and the ability to send the robot to specific rooms on demand.

AutoWash Dock: emptying, washing, and drying

Benefit: The AutoWash dock is a major convenience feature: it auto-empties the robot’s dust bin, periodically washes and refreshes the mop pads, and dries them so the unit is ready for the next run. iRobot states the dock supports up to 75 days of auto-emptying and about 4 weeks’ worth of mopping and pad washing under a specific usage pattern (source: listing, checked 2025).

Where it helps: Users who dislike handling dust bags or rinsing dirty mop pads after each use — families, allergy sufferers, or anyone seeking lower maintenance day-to-day.

Flexible cleaning modes and carpet-auto lift

Benefit: The robot offers vacuum-only, mop-only, combo cleaning, or a sequence where it vacuums first then mops. Mop pads also auto-lift when the robot detects carpet to prevent wetting rugs and carpets.

Where it helps: Mixed-surface homes where you want continuous transitions between vacuuming and mopping without manual intervention. This is handy when you’re running a whole-home clean and don’t want to block off carpets.

Customizable cleaning: suction levels and repeat passes

Benefit: Choose among multiple suction settings (the listing mentions four levels) and program repeat passes or extra scrubbing in high-traffic areas. These options put more control in your hands to prioritize quiet operation, battery life, or deep cleaning.

Where it helps: Tailoring the robot’s behavior to specific rooms — higher suction for carpets or pet areas, lower suction for quiet overnight runs, and repeat passes for entryways that get dirty faster.

Clean Zones, Keep Out Zones, and smart scheduling

Benefit: Use the app to set Clean Zones to target problem spots and Keep Out Zones to protect fragile areas or stop the robot from entering rooms. Scheduling through the Roomba Home app is straightforward and gives time estimates so you know how long a job will take.

Where it helps: Directing the robot to kitchen spills or preventing it from disturbing baby play areas and pet bowls. Useful for fine-grained control when room-by-room cleaning matters.

Three-way control: voice, app, or onboard buttons

Benefit: Start, pause or schedule cleaning using a voice assistant, the Roomba Home app, or the robot’s onboard controls. Multiple control options mean the robot adapts to how you prefer to manage tasks.

Where it helps: Hands-off households that want voice convenience, people who prefer app customization, and those who just want a quick press of a button on the robot.

Performance & Use

Setup is straightforward: place the AutoWash dock against a wall near a power outlet, position the robot on the dock to charge and register it to the Roomba Home app. The app guides you through mapping and initial runs; LiDAR mapping typically completes in the first couple of cleans to build an accurate floor plan.

Daily use: run a scheduled clean or launch a specific room clean when needed. The AutoWash dock reduces hands-on chores by handling debris disposal and mop pad maintenance. For mopping, you can use plain water or a compatible cleaning solution; the listing allows both options (source: listing, checked 2025). Take care with sensitive floor finishes — always test any cleaning solution in a small area first.

Maintenance tips:

• Check and replace filters and brush components per the app’s health indicators.
• Empty any remaining debris reservoir if prompted, though the base handles most auto-emptying needs.
• Inspect mop pads periodically for wear; even with automatic washing, pads will eventually need replacement.
• Keep the dock’s water/solution reservoir and drainage areas clean to prevent odors.
• Update firmware through the app to get navigation and feature improvements.

Practical notes:

• The pad auto-lift avoids wetting carpets, but some high-pile rugs may still confuse the robot. Use Keep Out Zones where necessary.
• For very stubborn, set-in stains you’ll still need a manual treatment — the robot is designed for regular maintenance and spill management rather than heavy restoration.

Pros vs Cons

Who Should Buy

• Busy households that want a largely hands-off vacuum-and-mop solution.
• Pet owners who need stronger suction and automatic debris management.
• People with mixed floor types who want coordinated vacuum + mop behavior and pad auto-lift for carpets.
• Those who value mapping, zone control, and the convenience of a self-washing dock.

Who Shouldn’t Buy

• Buyers on a tight budget who prefer a basic robot vacuum without an AutoWash dock.
• Homes with many very high-pile rugs or unusual thresholds where robot navigation is likely to struggle.
• People who need detailed technical specs (battery runtime, exact dimensions) before purchase — those specifics are not listed in the product details provided.
• Users who prefer to avoid any consumable costs for pads, filters, or dock supplies.
