Price Comparison

When comparing the iRobot Roomba® 405 Combo with the Robot Vacuum Cleaner with Mop, there is a significant price difference. The iRobot Roomba® 405 Combo is priced at £349.00, while the Robot Vacuum Cleaner with Mop comes in at a more budget-friendly £178.48. This price disparity of over £170 makes the Airzeen option an attractive choice for those who prioritise cost-effectiveness without sacrificing essential features.

The higher price of the iRobot model can be attributed to its advanced functionalities and additional features, such as the AutoWash Dock. However, for users looking for a capable robotic vacuum at a lower price point, the Robot Vacuum Cleaner with Mop offers considerable value, making it a strong contender in this price-sensitive market.

Suction Power

Suction power is a critical consideration for any vacuum, and in this comparison, the iRobot Roomba® 405 Combo shines with its robust suction capabilities. It boasts up to 70 times more suction power compared to the older Roomba 600 series, providing a thorough clean for various debris types, from crumbs to pet hair.

In contrast, the Robot Vacuum Cleaner with Mop delivers a respectable 10,000Pa of suction power. While this is impressive, especially for a device in its price range, it does not match the iRobot's performance. Therefore, if strong suction is your primary concern, the iRobot Roomba® 405 Combo is the superior choice.

Mopping Functionality

Both products offer mopping functionalities, but they differ significantly in their effectiveness and user experience. The iRobot Roomba® 405 Combo features DualClean Mop Pads and SmartScrub technology, which provide 2x deeper scrubbing and can be used with cleaning solutions or plain water. This advanced mopping system allows for a more thorough clean, ensuring that even tougher stains are addressed effectively.

On the other hand, the Robot Vacuum Cleaner with Mop also combines vacuuming and mopping, but its functionality is less sophisticated. While it can perform both tasks simultaneously, users must remove the mop holder when cleaning carpets to avoid wetting them. Therefore, for those prioritising mopping efficiency, the iRobot Roomba® 405 Combo is the clear winner.

In terms of navigation technology, the iRobot Roomba® 405 Combo utilises ClearView LiDAR, which enables it to map your home quickly, avoid obstacles, and navigate effectively even in low light conditions. This ensures a structured cleaning pattern, maximising coverage and efficiency.

Conversely, the Robot Vacuum Cleaner with Mop employs advanced LiDAR navigation as well, creating precise maps and planning efficient cleaning routes. It supports up to five maps, making it suitable for multi-level homes. Both models offer impressive navigation capabilities, but the iRobot's efficiency in dark rooms gives it an edge in this category.

Auto-Emptying and Maintenance

The iRobot Roomba® 405 Combo comes equipped with an AutoWash Dock, which automates several maintenance tasks. It can empty itself for up to 75 days and wash its mopping pads, providing a hands-off cleaning experience that is particularly beneficial for busy households. This feature significantly reduces the frequency of user intervention required for maintenance.

In comparison, the Robot Vacuum Cleaner with Mop features a bagless self-emptying system that allows for up to 90 days of cleaning with a reusable dust cup. While it offers a convenient solution, it lacks the comprehensive maintenance capabilities of the iRobot. Users seeking minimal upkeep will find the iRobot Roomba® 405 Combo more appealing due to its advanced auto-emptying and pad washing functions.

App Functionality

When it comes to app functionality, both models offer user-friendly applications that enhance the cleaning experience. The iRobot Roomba® 405 Combo's app allows for custom cleaning routines, time estimates, and filter health checks, providing detailed insights into cleaning operations.

The Robot Vacuum Cleaner with Mop also offers an app that enables custom schedules, no-go zones, and room targeting. However, it requires a 2.4GHz WiFi connection for compatibility. While both applications are effective, the iRobot’s app may provide more robust features for users who appreciate detailed control and monitoring of their cleaning sessions.

Runtime and Efficiency

The iRobot Roomba® 405 Combo does not specify its exact runtime, but it is designed to efficiently clean areas before returning to its dock for recharging. On the other hand, the Robot Vacuum Cleaner with Mop boasts an impressive runtime of up to 180 minutes in ECO mode. This extended battery life allows users to cover larger areas without interruption.

However, the effectiveness of any vacuum also depends on how well it navigates and cleans the area before needing a recharge. The iRobot’s superior navigation and mapping technology may allow it to clean more efficiently in a shorter period, despite not having an explicitly stated runtime.

Which should you buy?

Ultimately, the decision between the iRobot Roomba® 405 Combo and the Robot Vacuum Cleaner with Mop depends on your priorities. If you are looking for advanced features, superior suction power, and comprehensive maintenance capabilities, the iRobot Roomba® 405 Combo is the best choice, albeit at a higher price of £349.00.

Conversely, if budget constraints are a primary concern and you require a capable vacuum with decent suction and mopping capabilities, the Robot Vacuum Cleaner with Mop at £178.48 offers excellent value. Therefore, assess your cleaning needs and budget to determine which robotic vacuum best fits your lifestyle.
