AI Verdict
A 2-in-1 robot vacuum and mop with LiDAR navigation and an AutoWash dock, but its mopping and deep carpet cleaning performance are below average.
This Roomba offers a convenient 2-in-1 solution with a feature-rich AutoWash dock for self-emptying and pad maintenance. However, its actual cleaning performance, particularly on carpets and for mopping, falls short of expectations for its price band, making it a better fit for specific floor types and user priorities.
If deep carpet cleaning and advanced mopping are priorities, look for models with higher suction ratings (e.g., 13,000 Pa or more) and features like hot water washing or heat drying for mop pads.

Pros
- ClearView LiDAR quickly maps homes and navigates efficiently, even in the dark, supporting up to 4 multi-level maps.
- AutoWash Dock self-empties debris for up to 75 days and washes/dries mop pads, reducing manual maintenance.
- DualClean Mop Pads lift automatically when sensing carpet, preventing wet carpets during combo cleaning.
- Offers multiple cleaning modes: vacuum-only, mop-only, combo clean, or vacuum first then mop.
- The robot handles hair, crumbs, and fine dust on hard floors with 70x more suction than Roomba 600 series.
Cons
- Actual suction power and airflow are below average compared to other robots, performing poorly on deep carpet cleaning and flattened pet hair pickup.
- Mopping leaves too much water on floors in some tests and lacks hot water washing or hot air drying for pads.
- The Roomba Home app is described as buggy, slow, unintuitive, and lacks granular controls for suction or water levels.
- Obstacle avoidance is limited, frequently running over objects shorter than 3 inches.
- No onboard water tank means frequent trips back to the base station to rewet mop pads during cleaning.
Dimension Scores
While it has 70x more suction than the Roomba 600 series and handles hard floors, its deep carpet cleaning and flattened pet hair pickup are significantly below average.
The AutoWash Dock provides hands-off maintenance for 75 days of self-emptying and automatic pad washing/drying, but the app is reported as buggy and unintuitive.
iRobot is known for its fit and finish, and the design carries a polished aesthetic, with a removable tray for manual deep cleaning of the dock.
The product is battery-powered and operates at 4 watts, but specific energy consumption for charging and dock operations is not detailed in the specs or reviews.
Best For
- Homes with mostly hard floors and low-pile rugs that need regular vacuuming and light mopping.
- Users who prioritize hands-off maintenance for up to 75 days of self-emptying and automatic pad washing/drying.
- Environments where precise room-by-room cleaning and virtual boundaries are needed via LiDAR mapping.
Not Recommended For
- Homes with thick carpets or significant pet hair embedded in carpets, due to below-average deep cleaning performance.
- Users expecting advanced obstacle avoidance for small, low-lying items.
- Anyone needing precise control over mopping wetness or hot water cleaning for stubborn stains.
Watch Out For
- The robot's suction power and airflow are below average, resulting in significantly poor deep carpet cleaning and only picking up about half of flattened pet hair in tests.
- Mopping performance can leave excessive water on floors and only has one water level setting, potentially leaving floors dirty.
- The app is buggy and slow, with firmware updates taking too long and lacking granular control over cleaning settings.
- Obstacle avoidance is limited; the robot will run over objects under 3 inches tall.
- The AutoWash dock, while convenient, is louder than average during the emptying process.

What Buyers Say
Many users, including Vacuum Wars, expressed disappointment with the Roomba Plus 405, noting that despite its new LiDAR navigation and spinning mop pads, its actual cleaning performance, especially on carpets, was a letdown. The app experience is also a recurring pain point, described as buggy and lacking fine-tuned controls.
“Honestly, I had high hopes for this Roomba with the auto-wash dock, but the mopping just leaves my floors too wet and it barely cleans my rugs. The app is a nightmare to use too, seriously frustrating. I paid too much for this.”
Common Praise
- The LiDAR navigation quickly maps the home and allows for precise, straight-line cleaning paths.
- The AutoWash Dock's ability to self-empty for 75 days and wash/dry mop pads is a major convenience.
- Mop pads lifting over carpets is a practical feature for mixed flooring homes.
- It effectively picks up debris like crumbs and fine dust on hard floors.
- The robot's ability to handle hair in the roller is better than previous generations, with only 17% hair tangled in tests.
Common Complaints
- Deep carpet cleaning performance is significantly below average, struggling with embedded dirt and pet hair.
- Mopping leaves too much water on floors and lacks hot water for better cleaning or hot air for faster drying.
- The Roomba Home app is buggy, slow, and lacks granular control over suction and water levels.
- Obstacle avoidance is poor for low-lying items, with the robot frequently running them over.
- The dock is noticeably loud during the self-emptying process.
- The robot makes frequent trips back to the base to rewet its mop pads due to the absence of an onboard water tank.
Ownership Tips
- The robot struggles with low-profile obstacles, requiring users to pre-clear floors of small items like cables or socks.
- The single water level setting for mopping means you can't adjust for different floor types or levels of dirt.
- Frequent app updates are often required, which can be time-consuming and sometimes fail.
- The dock's noise during emptying is noticeable, especially if running at night or in quiet environments.
- Despite the 75-day self-empty claim, the mop pads still need regular manual cleaning of the removable tray in the dock.
Frequently Asked Questions
Does the Roomba Plus 405 vacuum and mop simultaneously?
Yes, it can vacuum and mop at the same time. You can also choose to vacuum only, mop only, or vacuum first then mop.
How long does the AutoWash Dock hold debris?
The AutoWash Dock can self-empty debris for up to 75 days before needing the bag to be changed.
Does it avoid obstacles like shoes or cables?
It uses LiDAR for navigation and can avoid taller obstacles, but it frequently runs over low-lying items like shoes or cables that are shorter than 3 inches.
Can the mop pads be washed with hot water?
No, the AutoWash Dock washes and dries the mop pads, but it does not use hot water for washing or hot air for drying.
How well does it clean pet hair?
It handles pet hair on hard floors effectively with its 70x suction compared to the 600 series, but its performance on deeply embedded or flattened pet hair on carpets is below average.
Is the app easy to use?
User feedback indicates the app can be buggy, slow, and unintuitive, with a clunky interface and limited granular controls for cleaning settings.
Buying Guide
When looking at robot vacuum mops, you need to think about your floor types first. If you have mostly hard floors, a robot like this with spinning mop pads might be okay for light maintenance. But if you have a lot of carpet, especially with pets, you need to check the actual suction power and deep cleaning capabilities, not just marketing claims. Also, consider how much hands-on maintenance you're willing to do for the mop pads and dustbin.
LiDAR Navigation
This is like the robot having a precise map and GPS. It allows the robot to quickly map your home, clean in neat rows, and avoid obstacles it can 'see,' making cleaning more efficient and less random than older navigation types.
AutoWash Dock
This is your robot's self-care station. It automatically empties the dustbin, washes the mop pads, and dries them, meaning you don't have to deal with dirty pads or empty the bin for weeks.
Dual Spinning Mop Pads with Auto-Lift
Instead of just dragging a wet cloth, these pads spin to scrub floors. The 'auto-lift' feature is crucial if you have both hard floors and carpets, as it raises the pads to prevent wetting your rugs while vacuuming.
Suction Power (e.g., 70x vs. Roomba 600 series)
This tells you how much power the vacuum has to pick up dirt. A higher number generally means better cleaning, especially on carpets or for pet hair. However, marketing comparisons like '70x' need to be cross-referenced with real-world test results, as raw numbers don't always tell the whole story.
Alternatives
If this model doesn't fit, look for robot vacuums with higher measured suction power for deep carpet cleaning, advanced obstacle avoidance sensors (like front-facing cameras), and mopping systems that include hot water washing or heat drying for pads.
