Price Comparison

The Lefant M2 Robot Vacuum Cleaner with Mop is priced at £129.99, making it a significantly more affordable option compared to the iRobot Roomba® 405 Combo, which retails for £349.00. The substantial price difference of £219.01 could make the Lefant M2 appealing to budget-conscious consumers who still want reliable robotic cleaning capabilities. While the iRobot Roomba offers a range of advanced features, the question remains whether those features justify the higher price tag for an average household.

Cleaning Performance

In terms of suction power, the Lefant M2 boasts a strong 6000Pa suction capability, effectively removing dust, debris, and pet hair from multiple surfaces. On the other hand, the iRobot Roomba® 405 Combo claims to provide 70 times more suction compared to the Roomba 600 series, featuring advanced DualClean Mop Pads and a multi-surface rubber brush designed to tackle tough messes. This difference in cleaning performance could be a key consideration for households with pets or high foot traffic, as the iRobot may offer superior cleaning efficiency.

Mopping Functionality

Both models offer mopping capabilities, but they differ significantly in execution. The Lefant M2 features a 300ml water tank and three adjustable water levels, allowing it to mop floors effectively for various cleaning needs. In contrast, the iRobot Roomba® 405 Combo includes spinning DualClean Mop Pads and SmartScrub technology, which provides 2x deeper scrubbing power. This advanced mopping feature, combined with the option to use a cleaning solution, suggests that the Roomba may deliver a more thorough clean for stubborn stains compared to the Lefant M2.

When it comes to navigation, the Lefant M2 utilises advanced dToF laser navigation, enabling it to map and clean efficiently with three-level mapping capabilities. The iRobot Roomba® 405 Combo, however, employs ClearView LiDAR technology, allowing it to map homes quickly and clean in organised rows, even in low light. While both devices are designed to avoid obstacles and maximise cleaning coverage, the Roomba's technology may provide more precise navigation, which could result in a more effective cleaning routine.

Battery Life and Runtime

The Lefant M2 offers an impressive runtime of up to 140 minutes on a single charge, making it suitable for larger homes without frequent interruptions. In comparison, while the iRobot Roomba® 405 Combo does not specify its exact runtime, it compensates with an AutoWash Dock that provides 75 days of auto-emptying and up to 4 weeks of mopping and pad washing. This feature implies a more hands-off approach to maintenance, although it may not match the Lefant's runtime in a single cleaning session.

Smart Features and Control

Both the Lefant M2 and iRobot Roomba® 405 Combo come with smart features allowing for app control and voice commands. The Lefant M2 can be managed through the Lefant APP as well as via Alexa and Google Home, enabling users to schedule cleanings and adjust settings easily. The iRobot Roomba takes this a step further, offering a user-friendly Roomba Home app that provides custom cleaning routines and insights into room cleaning priorities. This additional level of customisation could be appealing for tech-savvy users who want more control over their cleaning schedules.

Maintenance and Convenience

Maintenance is a crucial factor in any robotic vacuum cleaner's appeal. The Lefant M2 requires manual emptying and maintenance, which might be less convenient for users who prefer a more automated solution. Conversely, the iRobot Roomba® 405 Combo's AutoWash Dock handles not only auto-emptying but also washing and refreshing the mop pads. This feature means less frequent hands-on maintenance, allowing users to enjoy a consistently clean home with minimal effort.

Which should you buy?

Deciding between the Lefant M2 and the iRobot Roomba® 405 Combo ultimately depends on your cleaning needs and budget. If you are looking for an economical choice that still offers solid vacuuming and mopping performance, the Lefant M2 is an excellent option at £129.99. However, if you desire advanced features, superior suction, and a more convenient maintenance experience, the iRobot Roomba® 405 Combo, despite its higher price of £349.00, may be the better investment for a busy household.
