Score Breakdown
Powerful Vacuuming for Daily Upkeep
The iRobot Roomba Plus 405 Combo, available in Black and Matte Black configurations, earns strong praise for its vacuuming capabilities. Owners frequently highlight its robust suction, noting its effectiveness in collecting pet hair and daily debris from both hard floors and short-pile carpets. Many pet owners, including those with multiple shedding animals, describe it as a "sanity saver" and "life changing" for keeping floors noticeably cleaner. The robot's ability to navigate under furniture and clean in methodical straight lines is a significant improvement over older, less intelligent models. While it excels at maintenance cleaning, some users caution that it does not entirely replace the need for occasional deep cleaning with a traditional vacuum, especially for stubborn dirt or tight corners it may miss. The rubber brushes are generally effective at preventing tangles, a common issue with pet hair.Mixed Results for Mopping
The mopping function of the Roomba Plus 405 Combo receives more varied feedback. Many appreciate the convenience of the dual spinning mop pads and the AutoWash dock, which automatically cleans and dries the pads. This feature is lauded for handling light dirt and spills, making it suitable for daily floor maintenance and leaving hard floors looking polished. However, owners frequently note that the mop is not designed for deep cleaning and struggles with dried-on food or tough stains. Some report issues with streaking, particularly when using the recommended iRobot cleaning solution, finding plain water to be more effective. Concerns also arise regarding the mop's coverage, with some observing that it misses areas near baseboards or that the small mop pads can sometimes push dirt around. The "mop after vacuum" feature is also criticized for its limitations, as the mop may clean the entire house even if the vacuum only cleaned a specific room.Intelligent Navigation with Persistent Quirks
Navigation is a solid point for the Roomba Plus 405 Combo, with its LiDAR technology enabling quick and accurate mapping of homes. Owners commend its ability to create detailed maps, designate rooms and "keep out" zones, and clean in efficient, straight lines. The robot's capacity to recognize different floors and adapt its cleaning path is also a highlight. Despite these advancements, the robot is not without its navigational quirks. Several users report instances of it bumping into furniture, pushing lightweight objects, or getting stuck under specific types of furniture or on rug edges. While it generally avoids obstacles like cords, some owners have experienced it getting tangled or even damaging cables. A recurring complaint involves the robot's battery management, with some units failing to save enough charge to return to the dock, or getting lost and dying before successfully redocking.Frustrating App Experience and Connectivity Challenges
The companion iRobot Home app and its connectivity are frequent sources of frustration for many owners. While some find the app intuitive for setting schedules and customizing cleaning routines, a significant number describe it as buggy, glitchy, and difficult to navigate. Connectivity issues, ranging from Wi-Fi dropouts to the robot losing communication with the cloud or the app, are commonly reported, often requiring reboots or resets. Voice assistant integration, particularly with Alexa, is also noted as inconsistent and inconvenient. Furthermore, the mapping process, though generally accurate, can be tedious, with some users reporting that map updates can delete previously set zones or schedules. The robot's internal sensors, particularly for the dustbin, are sometimes finicky, falsely indicating a full bin even when empty, which prevents cleaning cycles from starting. These software and connectivity challenges detract from an otherwise capable device, demanding patience and troubleshooting from owners.Value and Maintenance Expectations
For many, the iRobot Roomba Plus 405 Combo represents a worthwhile investment, especially when purchased on sale, due to the significant time and effort it saves in daily cleaning. However, the overall value is tempered by its price point and the ongoing demands of maintenance. Owners stress the importance of regular cleaning of the robot's brushes, filters, and sensors to maintain optimal performance, especially in homes with high pet hair volume. The dustbin, while automatically emptied by the dock, is often described as small and requiring frequent attention. Durability concerns are also present, with some units experiencing malfunctions or part failures within a year or two of use, leading to frustration with the product's longevity and customer support. While customer service has been helpful for some in resolving issues and providing replacements, others report unhelpful interactions with bots or lengthy hold times.The Good
- Effective Vacuuming: Owners consistently praise its strong suction and ability to pick up significant amounts of pet hair and everyday debris from both hard floors and carpets.
- Smart Navigation & Mapping: The robot uses LiDAR for accurate and fast home mapping, cleaning in methodical straight lines, and generally avoiding obstacles.
- Convenient AutoWash Dock: The dock automatically empties the dustbin, washes and dries the mop pads, and refreshes water, significantly reducing manual maintenance.
- Time-Saving for Daily Chores: Many users find it a valuable helper for daily floor upkeep, saving considerable time and effort, especially in busy households with pets.
The Bad
- Inconsistent Mopping Performance: While suitable for light maintenance, the mopping feature struggles with dried-on stains, can leave streaks, and sometimes misses edges or leaves puddles.
- App & Connectivity Issues: The companion app is frequently criticized for being buggy, unintuitive, and prone to connectivity problems, affecting scheduling and control.
- Reliability & Durability Concerns: Several owners report units malfunctioning within months or a year, experiencing issues like failing to dock, getting lost, or parts breaking prematurely.
- Frequent Maintenance Demands: Despite the AutoWash dock, the robot requires regular manual cleaning of sensors, brushes, and the dustbin, which is often cited as small and prone to false "full" warnings.
What owners actually said
“Cleans better when you choose vacuum then mop, but in a pinch and need the help it’s amazing! Great suction. Great mop pad cleaning. Very loud when running so better to do while not home. App is easy and creating a map is wonderful for your specific needs.”
“Lasted about 5 years before it just fell apart. But worked well while it lasted.”
“I mostly like it. I don’t like having to move small rugs and be sure any cords are well up and away so they don’t get caught up in the vacuum. I don’t like the app. It seems a little hard to comprehend. It need’s simpler quick start instructions.”
