- •Combines vacuuming and mopping in one device, saving the hassle of multiple cleaning tools.
- •AutoWash Dock autonomously washes, dries, and refreshes spinning mop pads to keep them clean without manual effort.
- •Self-emptying dustbin in the dock holds debris for up to 75 days, drastically reducing maintenance.
- •ClearView LiDAR navigation maps the home quickly and efficiently, enabling smarter, more organized cleaning routes that avoid obstacles and stairs.
- •App offers easy setup with room mapping, naming, customizable Keep Out zones, and scheduling for automatic cleaning routines.
- •Smart mop pad lift feature prevents wetting carpets, with automatic carpet detection to protect rugs and carpets during mopping.
- •Vacuum function boosts suction automatically on carpets and lifts pet hair, allergens, and debris with up to 70X more suction power compared to older Roomba 600 models.
- •Quiet operation suitable for early morning or late-night cleaning without disturbing the household.
- •Intelligent self-cleaning cycle in the dock helps prevent mildew and musk build-up, keeping the system fresh.
- •Compatible with Alexa, Siri, and Google Assistant for convenient voice control.
Cons
- •Struggles significantly with throw rugs, often getting tangled or dragging mop pads across carpets despite the pad-lift feature.
- •Frequent connectivity and app issues, including losses of connection mid-clean and frustrating repeated factory resets needed.
- •Customer service response is slow and often unhelpful when technical or app problems arise.
- •Vacuuming sometimes leaves dirt lines along area rugs and struggles with hair pickup due to the main roller clogging easily with wrapped hair.
- •Noticeably noisier than some previous Roomba models.
- •Mapping occasionally shows false stuck bumper alerts even in clear spaces, disrupting cleaning runs.
- •Sensor fails to detect pet waste, potentially causing messy run-ins during cleaning.
- •Mop function with rotating pads works reasonably but may not always meet expectations for deep scrubbing on tough grime.
- •Battery life is reliable but not exceptional on longer or multi-floor cleaning sessions.
- •Some users experienced performance decline after initial runs.
Bottom Line
The iRobot Roomba Plus 405 is a compelling all-in-one combo vacuum and mop solution that truly streamlines home floor care with its advanced AutoWash Dock and smart LiDAR navigation. It stands out for its autonomous maintenance features like self-emptying and mop pad washing, cutting down daily hassle significantly. However, if you have many throw rugs or rely heavily on flawless app connectivity, prepare for some frustration — app glitches and rug tangling have been notable pain points. For pet owners or homes with tricky rugs, considering alternatives with more robust hair handling or fewer connectivity hiccups might be wise. Still, if you seek a high-tech, largely hands-off cleaner for a predominantly hard floor home and appreciate voice assistant control, this robot offers impressive convenience and cleaning power.
