Review
The Roomba Plus 405 pairs iRobot's AutoWash dock — which states up to 75 days of auto-emptying plus four weeks of mopping and pad washing based on one mopping run per week — with a LiDAR-guided combo robot. ClearView LiDAR maps a home quickly while its sensors steer around obstacles and prevent falls down stairs.
The DualClean mop pads add SmartScrub, a press-down scrubbing motion iRobot says cleans twice as deep as its standard vacuum-and-mop mode, and the pads lift automatically when the robot detects carpet. Four suction levels and the option to vacuum-only, mop-only, combo-clean, or vacuum first then mop provide useful control. The Roomba Home app adds cleaning-time estimates and filter-health checks alongside scheduling and room targeting.
It's a strong pick for buyers who want the iRobot ecosystem and a long stated self-empty interval without prioritizing every premium dock feature.
Pros
- 75-day self-empty — the longest interval of the three we track
- AutoWash dock washes and dries the mop pads automatically
- SmartScrub press-down mopping for deeper cleaning on hard floors
- Long stated self-empty interval reduces routine bin handling
Cons
- No absolute suction (Pa) figure published — only a relative marketing claim
- Dock water tanks still need periodic rinsing and refilling
- No manufacturer claim of hot-water mop washing
Ideal for: iRobot fans and pet owners who want the longest self-empty interval with light mopping, without paying flagship prices.
