Price Comparison

The Vexilar W9 Robot Vacuum Cleaner with Mop is priced at £123.99, making it significantly more affordable than the iRobot Roomba® 405 Combo, which retails for £349.00. This price difference of £225.01 can be a crucial factor for budget-conscious consumers seeking effective cleaning solutions without breaking the bank. While the Roomba offers advanced features, the Vexilar presents a strong case for those who prioritise affordability while still wanting a capable robotic vacuum.

Cleaning Performance

When it comes to suction power, the Vexilar W9 boasts an impressive 8000Pa, which is essential for effectively lifting dust, dirt, and pet hair from various surfaces. In contrast, the iRobot Roomba 405 claims to have 70 times more suction compared to its older models, although it does not provide a specific measurement for its suction power. Both models are designed for deep cleaning, but the Vexilar’s extreme suction might make it more adept at tackling deeply embedded debris. The choice between these two cleaning performances may depend on the specific cleaning needs of the user.

Mopping Capability

The Vexilar W9 offers a 3-in-1 functionality, allowing it to vacuum, sweep, and mop simultaneously, which is particularly advantageous for those wanting comprehensive cleaning in one pass. It features a 2-in-1 water tank and dustbin with adjustable water levels, ensuring that different floor types are cared for without the risk of excessive moisture. The iRobot Roomba 405, on the other hand, features DualClean Mop Pads and SmartScrub technology that promise deeper cleaning with two times the scrubbing power compared to standard modes. Each model presents unique mopping strengths, catering to various preferences for cleaning methods.

The Vexilar W9 employs intelligent 360° Laser Navigation, allowing it to map an entire home in just 15 minutes, which is an impressive feat for efficient cleaning. It can store up to five floor maps and offers customisable no-go zones via its app. The iRobot Roomba 405 also utilises ClearView LiDAR for quick mapping and obstacle avoidance, and it cleans in neat rows, even in low light. While both devices feature advanced navigation systems, Vexilar's capability to store multiple maps may be more beneficial for multi-storey homes.

Battery Life and Efficiency

The Vexilar W9 is powered by four 2600mAh batteries, providing a runtime of up to 150 minutes. When the battery level drops below 15%, it automatically docks to recharge and resumes cleaning from where it left off. In contrast, the iRobot Roomba 405 does not specify its battery life but boasts an AutoWash Dock that allows for 75 days of auto-emptying and continuous cleaning with minimal intervention. If long cleaning sessions without needing to recharge are a priority, the Vexilar W9 may be the more efficient option.

Smart Features

The Vexilar W9 includes a variety of smart features, such as scheduled cleaning, room customisation, and live tracking. Users can adjust cleaning routes and set virtual walls to protect sensitive areas. The iRobot Roomba 405 also offers a user-friendly app that enables custom cleaning routines, filter health checks, and insights into which areas require attention. Both models provide advanced smart capabilities, but the specific features and ease of use will vary depending on user preference and how they plan to integrate the vacuum into their daily routines.

User Experience and Control

With the Vexilar W9, users can fully customise their cleaning experience through an app, allowing for real-time monitoring and adaptability to specific cleaning needs. The iRobot Roomba 405 enhances user interaction with voice control compatibility, enabling users to command the vacuum through Alexa, Siri, or Google Assistant. While both vacuums offer excellent user experience features, the Roomba's voice control may appeal more to those seeking hands-free operation.

Which should you buy?

Choosing between the Vexilar W9 Robot Vacuum Cleaner with Mop and the iRobot Roomba® 405 Combo ultimately depends on your specific cleaning needs and budget. If you prioritise affordability and robust cleaning power, the Vexilar W9 offers significant value at £123.99, especially with its strong suction and multifunctionality. However, if you're willing to invest more for advanced features like the AutoWash Dock and superior mopping capabilities, the iRobot Roomba 405 at £349.00 may be worth the extra cost. Consider your home layout, cleaning preferences, and how much you are willing to spend to determine which robot vacuum fits your lifestyle best.
