Price Comparison

The roborock Saros 20 is priced at £1,098.99, while the Dyson Spot+Scrub™ AI Wet Robot Vacuum with Mop is significantly cheaper at £849.00. This £249.99 difference in price may influence your decision based on your budget and the features you desire. Despite the higher price, the roborock offers advanced features that justify its cost, appealing to those who prioritise cutting-edge technology and comprehensive cleaning capabilities. Conversely, the Dyson presents a more budget-friendly option without compromising too much on functionality, making it attractive for those seeking a capable robot vacuum at a lower price point.

Cleaning Performance

In terms of cleaning power, the roborock Saros 20 boasts an impressive 36,000 Pa suction capability, making it highly effective at removing dust, pet hair, and debris from various surfaces. This robust suction power ensures that even deep-seated dirt is extracted efficiently. In contrast, the Dyson operates with a powerful 18,000 Pa motor, which, while still effective, may not match the depth of cleaning offered by its competitor. The roborock also features a dual anti-tangle system, ideal for pet owners, reducing the hassle of manual brush cleaning, whereas the Dyson employs advanced AI to intelligently adapt its cleaning methods based on the surface, providing a tailored cleaning experience.

The roborock Saros 20 integrates the StarSight Autonomous System 2.0, leveraging advanced 3D ToF sensors and RGB vision for precise navigation and mapping. This technology allows the robot to recognise over 300 obstacles, minimising interruptions and enhancing cleaning efficiency. The Dyson, on the other hand, utilises high-speed LiDAR for mapping and navigation, which also aims to eliminate missed areas. While both robots are equipped with sophisticated navigation systems, the roborock's superior obstacle recognition may contribute to a more thorough clean in complex environments.

Design and Accessibility

The design of the roborock Saros 20 is tailored for accessibility, with a slim profile that allows it to glide under furniture as low as 3.13 inches. This feature ensures that hidden dust and debris are not overlooked, providing a more comprehensive clean. In comparison, the Dyson's design focuses on functional aesthetics, featuring a precisely angled blade that reveals hidden stains and dust. However, it may not have the same low-profile advantage as the roborock. The roborock's emphasis on accessibility makes it a better choice for homes with lower furniture, ensuring that every corner is reached.

Self-Cleaning and Maintenance

For those who value convenience, the roborock Saros 20 comes with a fully automated dock that supports extensive self-cleaning features. It includes a one-piece cleaning tray, hot water washing, and up to 65 days of auto dust emptying, delivering a hands-free experience. In contrast, the Dyson employs a 12-point hydration system that cleans its roller during operation, ensuring that it uses clean water throughout the cleaning process. While both models feature self-cleaning capabilities, the roborock offers a more comprehensive solution that significantly reduces the frequency of manual maintenance, making it ideal for busy households.

Advanced Features

The roborock Saros 20 is packed with advanced features, such as FlexiArm technology that extends the side brush and mop for edge-to-edge cleaning. This capability allows it to tackle dirt in corners and behind curtains, ensuring no spots are missed. Meanwhile, the Dyson Spot+Scrub™ offers innovative stain detection using a high-contrast green light, revealing hidden stains and adapting its cleaning power accordingly. While both products feature unique advanced functionalities, the roborock's all-encompassing approach to cleaning and its ability to reach hidden areas may provide a more thorough overall cleaning experience.

User Experience

User experience is a significant factor when choosing a robotic vacuum. The roborock Saros 20's integrated app allows for seamless control, including marking areas for cleaning, while its advanced navigation ensures a smoother cleaning process with fewer interruptions. On the other hand, the Dyson's data-driven cleaning reports provide users with insights into cleaning intensity and coverage, allowing for more informed cleaning practices. Both options offer a user-friendly experience, but the roborock's emphasis on comprehensive and automated cleaning may appeal more to those who prefer minimal input during operation.

Which should you buy?

In conclusion, the choice between the roborock Saros 20 and the Dyson Spot+Scrub™ AI Wet Robot Vacuum with Mop ultimately depends on your specific cleaning needs and budget. If you prioritise superior suction power, advanced navigation, and extensive self-cleaning features, the roborock Saros 20 is worth the investment at £1,098.99. However, if you're looking for a capable robot vacuum at a more affordable price of £849.00, the Dyson offers a solid alternative with innovative stain detection and effective cleaning capabilities. Your decision should align with your priorities, whether it's cutting-edge technology or budget-friendly efficiency.
