Price Comparison
The iRobot Roomba Max 705 is priced at C$669.99, while the iRobot Roomba Plus 405 is available for a more budget-friendly C$469.99. This C$200 price difference may influence your decision, especially if you are looking for essential features without breaking the bank. The Roomba Plus offers solid performance at a lower cost, making it a more accessible option for those who may not need the advanced features of the Max 705.
Cleaning Technology
The iRobot Roomba Max 705 boasts extreme power-lifting suction that is 180 times more effective in Spot Clean mode compared to the Roomba 600 series. In contrast, the Roomba Plus 405 offers 70 times more suction than the same series, which is impressive but falls short of the Max 705's capabilities. Both models utilize advanced mapping technologies, with the Max 705 featuring ClearView Lidar for optimal coverage and navigation, while the Plus 405 also employs ClearView Lidar but focuses on neat rows even in darkness. While both robots excel in cleaning efficiency, the Max 705's superior suction power makes it the better choice for tackling tougher messes.
Auto-Empty and Maintenance Features
The Roomba Max 705 comes with an AutoEmpty Dock that can trap debris as small as 0.7 microns, providing up to 75 days of hands-free cleaning. This feature is particularly beneficial for those with allergies or pets. Conversely, the Roomba Plus 405 also includes an AutoWash Dock, which not only empties the vacuum but also washes the mop pads, ensuring optimal cleaning performance for up to four weeks. While the Plus 405 offers a comprehensive solution for mopping and vacuuming, the Max 705's extended hands-free cleaning capability may appeal more to users who prioritise minimal maintenance.
Mopping Capabilities
While both robots excel in vacuuming, the Roomba Plus 405 has the edge when it comes to mopping. It features DualClean Mop Pads and SmartScrub technology, providing 2x deeper scrubbing for thorough cleaning, while also offering the ability to mop with a cleaning solution or just water. The Max 705, on the other hand, focuses primarily on vacuuming, making it less versatile in this regard. If mopping is a crucial aspect of your cleaning needs, the Roomba Plus 405 is the more suitable option.
Smart Features and App Integration
Both the Roomba Max 705 and the Roomba Plus 405 come equipped with the new Roomba Home App, allowing for detailed control and custom cleaning routines. The Max 705 allows users to select specific rooms for cleaning, adjust suction levels, and utilize features like the advanced Dirt Detect Technology. The Plus 405 also offers room-specific cleaning through Clean Zones and the ability to set Keep Out Zones. While both models provide extensive smart features, the Max 705's nuanced control over cleaning settings and data on dirt detection may give it an edge for tech-savvy users.
Design and Aesthetics
In terms of design, both the Roomba Max 705 and the Roomba Plus 405 are crafted to blend seamlessly with modern home decor. The Max 705 is described as having elegant finishes and textures, making it a stylish addition to any living space. The Plus 405 also maintains a sleek design but focuses more on functionality with its AutoWash dock. While both models are aesthetically pleasing, the Max 705 may appeal to users looking for a more refined look in addition to high performance.
Performance on Different Surfaces
When it comes to versatility on various floor types, both the Roomba Max 705 and the Roomba Plus 405 excel. The Max 705's patented rubber brushes effectively adapt to different surfaces, enhancing its ability to clean carpets and hard floors alike. The Plus 405 also adapts well, with its mop pads lifting automatically when detecting carpet. While both models are adept at multi-surface cleaning, the Max 705's powerful suction and advanced brushes may provide superior performance on challenging surfaces, particularly for homes with pets.
Which should you buy?
The choice between the iRobot Roomba Max 705 and the iRobot Roomba Plus 405 ultimately depends on your cleaning needs and budget. The Roomba Max 705, priced at C$669.99, offers superior suction power, extended hands-free cleaning, and advanced features for those seeking the best performance. On the other hand, the Roomba Plus 405, at a more affordable C$469.99, provides excellent mopping capabilities and smart features that cater well to everyday cleaning tasks. If cost is a priority and mopping is essential for you, the Plus 405 is a strong contender. However, for those who desire top-notch vacuuming performance and less frequent maintenance, the Max 705 is the clear winner.
