Price Comparison
The roborock Qrevo Edge 2 is priced at £799.99, making it a more budget-friendly option compared to the roborock Saros 20, which is priced at £1,098.99. The significant price difference of £299 can be a decisive factor for consumers looking for efficient robotic cleaning solutions without breaking the bank. While both models offer advanced cleaning features, the Qrevo Edge 2 provides a solid performance at a lower price point, appealing to those who want effective cleaning without the premium cost associated with the Saros 20.
Suction Power
When it comes to suction power, the roborock Saros 20 excels with an impressive 36,000 Pa suction capability, significantly outpacing the Qrevo Edge 2, which offers 25,000 Pa. This 44% increase in suction power means that the Saros 20 can remove deeper embedded dirt and debris, making it particularly advantageous for homes with carpets or heavy pet hair. If maximum suction is a priority, the Saros 20 is clearly the superior choice, ensuring a thorough clean across various floor types.
Mopping Capability
Both the Qrevo Edge 2 and Saros 20 feature mopping systems, but the Saros 20 takes the lead with its fully automated dock that enhances mopping coverage and includes advanced features like 100°C hot water washing and self-cleaning maintenance. The Qrevo Edge 2 offers an upgraded mopping system with 8N downward pressure, suitable for tackling stubborn stains. However, the Saros 20 provides a more comprehensive hands-free cleaning experience, ensuring that mopping is not only effective but also less labour-intensive for the user.
Navigation Technology
The navigation capabilities of both models are impressive, but the Saros 20's StarSight Autonomous System 2.0 offers a more advanced mapping experience. It utilises 3D ToF sensors and RGB vision to create real-time maps and can recognise over 300 obstacles, reducing missed spots and enhancing cleaning efficiency. In contrast, the Qrevo Edge 2 employs the RetractSense Navigation System, which is effective but does not match the level of sophistication found in the Saros 20. For users prioritising seamless navigation and obstacle avoidance, the Saros 20 is a clear winner.
Design and Size
In terms of design, the Qrevo Edge 2 boasts an ultra-slim profile at just 3.14 inches, allowing it to navigate under low furniture easily. The Saros 20 is also designed to fit under furniture but has a slightly taller profile at 3.13 inches. While both robots can clean under sofas and beds, the Qrevo Edge 2's design is specifically tailored for extreme low spaces. For those with low-profile furniture, the Qrevo Edge 2 may be the better option, while the Saros 20 still maintains strong cleaning capabilities with its advanced features.
Maintenance
Maintenance is a crucial factor for robotic vacuums, and here the Saros 20 offers a more sophisticated solution with its fully automated dock. This dock features a one-piece cleaning tray that significantly boosts mop coverage and includes functionalities like self-cleaning maintenance and up to 65 days of auto dust emptying. The Qrevo Edge 2's maintenance features are solid but less advanced, lacking the comprehensive hands-free capabilities of the Saros 20. For users who desire a truly low-maintenance experience, the Saros 20 will be the preferred model.
User Experience
Both models promise a user-friendly experience, but the Saros 20's combination of advanced navigation, high suction power, and automated maintenance offers a more comprehensive solution. The Qrevo Edge 2 is effective and easier on the wallet, making it a good choice for budget-conscious consumers. However, those willing to invest more for enhanced features and performance will find the Saros 20 to provide superior value in terms of user experience, especially in larger homes or those with pets.
Which should you buy?
Choosing between the roborock Qrevo Edge 2 and the roborock Saros 20 ultimately depends on your specific cleaning needs and budget. The Qrevo Edge 2 is an excellent option for those seeking effective cleaning at a lower price point of £799.99, with solid suction and user-friendly features. On the other hand, if premium suction power, advanced navigation, and hands-free maintenance are your priorities, the Saros 20, priced at £1,098.99, is the superior choice. Each model excels in different areas, so consider what features are most important to you before making a decision.
