Price Comparison

When it comes to price, the Lefant M310 Ultra Robot Vacuum Cleaner with Mop is significantly more affordable at £150.77, compared to the iRobot Roomba® 405 Combo, which is priced at £349.00. This difference of £198.23 makes the Lefant a compelling option for budget-conscious consumers seeking a robot vacuum with mopping capabilities. While the iRobot model offers advanced features and a more sophisticated design, the Lefant still delivers essential cleaning functions at a fraction of the cost, making it an attractive choice for everyday cleaning needs.

Cleaning Performance

The iRobot Roomba® 405 excels in cleaning performance with its strong suction, boasting up to 70 times more power compared to Roomba's 600 series. It features a dual-clean mop pad system that provides deep scrubbing capabilities. In contrast, the Lefant M310, while equipped with a respectable 6000Pa suction, offers a more basic cleaning experience with a fixed water output for mopping tasks. While both models effectively tackle everyday messes, the Roomba’s superior suction power and advanced mopping function give it a distinct edge for those with more demanding cleaning requirements.

In terms of navigation, the iRobot Roomba® 405 features ClearView LiDAR technology, enabling it to quickly map your home and navigate efficiently—even in low-light conditions. This technology allows it to avoid obstacles and clean in neat rows. On the other hand, the Lefant M310 employs ToF laser navigation, which, while effective for real-time scanning of its surroundings, lacks the advanced mapping capabilities of the Roomba. This means that the Roomba can provide a more thorough clean with less chance of missing spots, making it ideal for larger or more complex spaces.

Mopping Capability

The mopping function is a key feature differentiating these two models. The iRobot Roomba® 405 is designed for serious mopping, equipped with dual mop pads and a scrubbing function that can clean with both water and compatible cleaning solutions. It promises to remove stains and grime effectively with its two times deeper scrubbing compared to standard modes. Conversely, the Lefant M310’s mopping capability is more basic, suitable for light tasks thanks to its 200ml water tank. While it can handle spills and stains, it lacks the deep-cleaning features of the Roomba, making it less effective for tougher messes.

Battery Life and Runtime

The Lefant M310 offers an impressive runtime of up to 170 minutes on a single charge, which is advantageous for cleaning larger areas without interruption. In comparison, the specific runtime for the iRobot Roomba® 405 is not detailed, but its advanced features may consume more power. The Lefant's extended runtime makes it suitable for homes requiring longer cleaning sessions, while the Roomba’s efficiency in navigating and cleaning may offset its potentially shorter runtime, depending on the cleaning demands.

Smart Features

The iRobot Roomba® 405 comes equipped with a user-friendly app that allows for custom cleaning routines, real-time updates on filter health, and the ability to target specific areas needing extra attention. It integrates seamlessly with voice assistants like Alexa, Siri, and Google Assistant. The Lefant M310 also features an app for monitoring cleaning paths but lacks the sophisticated scheduling and smart home integration found in the Roomba. This makes the Roomba a more versatile option for tech-savvy users looking to optimise their cleaning routines.

Design and Usability

In design, the iRobot Roomba® 405 boasts a sleek and sophisticated appearance, complemented by its AutoWash Dock, which handles cleaning pad maintenance and emptying for up to 75 days. This feature significantly reduces the need for user intervention. The Lefant M310, with its slim 7.9cm profile, is designed to navigate easily under furniture, which is beneficial for thorough cleaning in tight spaces. However, the lack of an automatic cleaning dock means users must be more hands-on with maintenance compared to the iRobot, potentially affecting overall usability.

Which should you buy?

Ultimately, the choice between the iRobot Roomba® 405 and the Lefant M310 hinges on your specific cleaning needs and budget. If you prioritise advanced features, superior suction, and effective mopping capabilities, the iRobot Roomba® 405 is worth the investment at £349.00. However, if you're looking for an economical option that still provides essential vacuuming and mopping functionality, the Lefant M310 at £150.77 offers solid performance for everyday cleaning tasks. Consider your home’s unique requirements and your willingness to invest in advanced technology when making your decision.
