Price Comparison

When considering price, the iRobot Roomba Plus 405 is the more budget-friendly option at C$469.99, compared to the DREAME L40s Ultra CE, which retails for C$649.99. This difference of C$180 may be significant for consumers looking for an effective robotic vacuum without breaking the bank. Despite the lower price, the Roomba Plus 405 offers robust features that compete well against the DREAME model, making it an attractive choice for those prioritising cost-effectiveness.

Suction Power and Cleaning Performance

In terms of suction power, the DREAME L40s Ultra CE stands out with an impressive 13,000Pa Vormax suction, designed to tackle both hard floors and carpets with ease. This high suction capability is particularly beneficial for deep cleaning, especially in homes with pets or heavy foot traffic. On the other hand, the iRobot Roomba Plus 405 boasts 70 times more suction compared to the Roomba 600 series, focusing on effective mopping and vacuuming. While the exact suction power isn't specified, the emphasis on strong suction and dual-clean mop pads suggests it effectively handles common household messes.

Mopping Capabilities

The DREAME L40s Ultra CE includes advanced features such as ultrasonic carpet sensing and automatic mop lifting, which optimises its cleaning strategy. This model’s design allows it to seamlessly transition from vacuuming to mopping, ensuring thorough cleaning across different surfaces. In contrast, the iRobot Roomba Plus 405 doubles down on mopping with its spinning DualClean Mop Pads and SmartScrub technology, providing two times deeper scrubbing compared to standard modes. This feature can be a strong selling point for those with significant spills or stains in their homes, showcasing the Roomba's dedication to mopping efficiency.

Maintenance and Convenience

The DREAME L40s Ultra CE excels in maintenance convenience with its all-in-one PowerDock, which allows for water refilling, mop washing, and air drying. This feature reduces the need for frequent manual intervention, promising up to 100 days of hands-free cleaning. In comparison, the iRobot Roomba Plus 405 offers an AutoWash dock that manages 75 days of auto-emptying and 4 weeks of mopping and pad washing. Both models provide substantial convenience, but the DREAME’s extensive hands-free capability may appeal more to busy households.

Smart Features and Mapping

When it comes to smart features, the DREAME L40s Ultra CE utilises Smart Pathfinder technology for accurate mapping and obstacle avoidance, enabling it to create editable maps for comprehensive cleaning. The voice and app control further enhance its usability, allowing commands via third-party assistants. Meanwhile, the iRobot Roomba Plus 405 employs ClearView LiDAR for quick mapping and obstacle avoidance, ensuring efficient cleaning patterns even in low light. Both models are equipped with smart navigation, yet the DREAME's detailed mapping capabilities may offer a more tailored cleaning experience.

Customisation and Control

The level of customisation available in the iRobot Roomba Plus 405 is notable, offering users options to vacuum, mop, or use a combination of both. The ability to set custom cleaning routines through the user-friendly Roomba Home app enhances user experience significantly. In contrast, the DREAME L40s Ultra CE allows voice and app control but is less specific about cleaning modes. While both models provide control via mobile apps, the Roomba’s range of cleaning options may cater better to specific cleaning needs in diverse environments.

Targeted Cleaning and Room Management

For targeted cleaning, the DREAME L40s Ultra CE allows users to issue commands through voice control or the app, making it easy to focus on specific areas. However, the Roomba Plus 405 takes this a step further with its Clean Zones feature, enabling users to send the robot directly to specific rooms or areas needing extra attention. Additionally, it includes Keep Out Zones to avoid certain spaces altogether. This level of control can be particularly beneficial for homes with varied cleaning requirements across different rooms.

Which should you buy?

Ultimately, the choice between the DREAME L40s Ultra CE and the iRobot Roomba Plus 405 comes down to personal priorities and budget. If you value high suction power, advanced maintenance features, and smart mapping, the DREAME L40s Ultra CE, priced at C$649.99, may be the better choice. However, if you are looking for an effective, budget-friendly option with strong mopping capabilities and excellent customisation features, the iRobot Roomba Plus 405 at C$469.99 stands out as a compelling option. Each model offers unique strengths, catering to different cleaning needs and preferences.
