Price Comparison
The XIAOMI Robot Vacuum X20 Pro is priced at £299.99, whereas the Roborock Saros 20 Robot Vacuum Cleaner with Mop comes in at a significantly higher price of £1,098.99. This makes the XIAOMI option more accessible for budget-conscious consumers looking for a capable robotic vacuum. While the Roborock Saros 20 offers premium features, the price difference of £799 is substantial and may not be justifiable for all users. Therefore, if you’re looking for a cost-effective solution, the XIAOMI Robot Vacuum X20 Pro is a compelling option.
Suction Power
When it comes to suction power, the Roborock Saros 20 dominates with an impressive 36,000 Pa compared to the XIAOMI Robot Vacuum X20 Pro's 7,000 Pa. This significant difference means that the Saros 20 can pull dust, pet hair, and debris from deep floor gaps much more effectively. For households with pets or heavy foot traffic, the enhanced suction of the Roborock may result in a noticeably cleaner home. Thus, if maximum suction is a priority, the Saros 20 stands out as the better choice.
Cleaning Technology
Both vacuums utilise advanced cleaning technologies, but they differ in approach and capabilities. The XIAOMI Robot Vacuum X20 Pro features a high-precision obstacle avoidance system that utilises a combination of 120° wide-area structured light and edge sensors. In contrast, the Roborock Saros 20 employs the StarSight Autonomous System 2.0, which uses advanced 3D ToF sensors to create accurate maps and recognise over 300 obstacles. This means that while the XIAOMI excels in avoiding collisions, the Roborock offers superior navigation and fewer missed spots, making it more efficient in complex environments.
Mopping Functionality
The XIAOMI Robot Vacuum X20 Pro includes a comprehensive mopping feature, with an automatic mop washing system and hot air drying capability. It also has a large 4L clean water tank, allowing it to cover an area of 120 square metres in one go. On the other hand, the Roborock Saros 20 offers a fully automated dock with enhanced mop coverage, self-cleaning capabilities, and a hot water washing feature. While both vacuums provide effective mopping, the Roborock's advanced docking system may appeal to those seeking a more hands-free experience.
Battery Life
The XIAOMI Robot Vacuum X20 Pro boasts a robust 5,200mAh battery that lasts up to 160 minutes in standard mode, making it suitable for larger homes without frequent recharges. In contrast, the battery performance for the Roborock Saros 20 is not explicitly stated, but its advanced features suggest a focus on high performance rather than extended runtime. For users prioritising long cleaning sessions without interruption, the XIAOMI may be the more practical option.
Design and Size
In terms of design, the Roborock Saros 20 has an ultra-slim profile that allows it to glide under furniture as low as 3.13 inches, ensuring it can reach hidden dust and pet hair. The XIAOMI Robot Vacuum X20 Pro, while effective, does not specify its height, which may limit its ability to access tighter spaces. If a sleek design that reaches those hard-to-clean spots is essential, the Roborock Saros 20 takes the lead.
Maintenance and Convenience
Maintenance is an important consideration when choosing a robotic vacuum. The XIAOMI Robot Vacuum X20 Pro features a convenient detachable cleaning tray, which simplifies the cleaning process. However, the Roborock Saros 20 excels with its fully automated dock that allows for up to 65 days of auto dust emptying, alongside a one-piece cleaning tray for mopping. This hands-free approach significantly reduces the effort required for maintenance, making the Roborock a more user-friendly option for households that prefer minimal upkeep.
Which should you buy?
Choosing between the XIAOMI Robot Vacuum X20 Pro and the Roborock Saros 20 ultimately depends on your specific needs and budget. The XIAOMI is a fantastic choice for those seeking an affordable, efficient vacuum with solid features, especially if you value longer battery life and easy maintenance. On the other hand, if your priority is maximum suction power, advanced navigation technology, and an automated cleaning experience, the Roborock Saros 20 justifies its higher price tag. Consider your cleaning requirements and choose accordingly.
