Overview of the Roborock Qrevo S5V and Saros 20
When it comes to robotic vacuums, the Roborock Qrevo S5V and the Roborock Saros 20 stand out with their advanced features and smart technology. The Qrevo S5V is priced at £399.98, while the Saros 20 is significantly higher at £1,098.99. This price difference reflects the varying capabilities of each model, which cater to different cleaning needs and preferences.
The Qrevo S5V is designed for thorough cleaning with its 12,000Pa suction power and all-in-one smart dock, making it a solid choice for many households. In comparison, the Saros 20 boasts an impressive 36,000Pa suction and industry-leading obstacle-crossing capabilities, making it more suitable for larger homes or those with complex layouts.
Suction Power
The Roborock Saros 20 features an exceptional suction power of 36,000Pa, which is three times that of the Qrevo S5V’s 12,000Pa. This significant difference means that the Saros 20 can effectively lift more embedded dirt and pet hair, especially from carpets and rugs. The higher suction power is particularly advantageous in homes with pets or heavy foot traffic, ensuring a cleaner environment with minimal effort.
On the other hand, the Qrevo S5V’s 12,000Pa suction is still robust and suitable for most cleaning tasks, especially on hard floors and low-pile carpets. While it may not match the Saros 20’s performance, it effectively handles everyday messes, making it a viable option for smaller homes or apartments.
Cleaning Technology
The Qrevo S5V is equipped with a comprehensive cleaning system that includes features like a zero-tangle system and a flexible mop design. Its SGS-certified zero-tangle system ensures that pet hair won’t wrap around the brushes, making it more convenient for pet owners. The dual spinning mops can mimic hand mopping, effectively tackling stubborn stains on various surfaces.
In contrast, the Saros 20 introduces the AdaptiLift Chassis 3.0, which allows it to glide over thresholds and uneven floors without losing suction. This feature enables it to clean carpets up to 1.18 inches deep and cross double-layer steps of up to 3.46 inches. Such advanced cleaning technology ensures that the Saros 20 can handle a broader range of cleaning scenarios, making it ideal for larger, multi-level homes.
Smart Navigation
When it comes to navigation, both the Qrevo S5V and the Saros 20 utilise advanced technologies to enhance their cleaning efficiency. The Qrevo S5V employs PreciseSense LIDAR navigation, which scans and maps the environment in 360°, allowing it to navigate around furniture and obstacles while creating detailed floor plans. This capability supports up to four floor plans, making it suitable for multi-level homes.
The Saros 20, however, takes navigation a step further with its StarSight Autonomous System 2.0, which uses advanced 3D ToF sensors and RGB vision for real-time mapping. This allows the Saros 20 to recognise over 300 obstacles, preventing interruptions during cleaning and ensuring complete coverage of the area. The enhanced navigation system in the Saros 20 could be a game changer for users with complex layouts or numerous obstacles.
Cleaning Modes and Control
Both robotic vacuums offer smart app control, allowing users to customise cleaning modes and schedules. The Qrevo S5V features a smart app that enables users to control various aspects of the cleaning process, including customising water flow for mopping, which can be adjusted up to 30 levels.
The Saros 20 also provides a high level of customisation through its app, allowing for edge-to-edge cleaning with its FlexiArm technology that extends the side brush and mop. This ensures that every corner and edge is reached, delivering a more thorough clean. While both models offer smart features, the Saros 20’s advanced technology may provide an edge for users seeking a more tailored cleaning experience.
Maintenance and Convenience
Maintenance is a crucial aspect of robotic vacuums, and both models offer hands-free solutions to ease this burden. The Qrevo S5V comes with an all-in-one smart dock that automatically empties dust into a 7-week storage bin, self-washes the mops, and uses hot air drying to prevent odour. This system allows for uninterrupted cleaning across large areas, making it particularly convenient for busy households.
Conversely, the Saros 20 features a fully automated RockDock that enhances mop coverage and water capacity while offering self-cleaning maintenance. With up to 65 days of auto dust emptying and hot water washing at 100°C, it presents a truly hands-free experience. This level of convenience may appeal more to users who prefer minimal intervention in their cleaning routines.
Design and Aesthetics
In terms of design, the Qrevo S5V and Saros 20 reflect modern aesthetics suited for contemporary homes. The Qrevo S5V features a sleek design that integrates well into various home settings, while its flexible mop arm is designed to reach hidden corners effectively.
The Saros 20 is ultra-slim, allowing it to glide under furniture as low as 3.13 inches. This design prioritises efficiency in cleaning areas that are often neglected. However, the more robust features of the Saros 20 come at a higher price, which may not be justifiable for every user.
Which should you buy?
In conclusion, the choice between the Roborock Qrevo S5V and the Saros 20 largely depends on your individual cleaning needs and budget. The Qrevo S5V, priced at £399.98, offers solid performance with effective suction, smart features, and convenient maintenance, making it ideal for smaller homes or those looking for efficient cleaning without a hefty investment.
On the other hand, the Saros 20, at £1,098.99, delivers unmatched suction power and advanced navigation, making it a superior choice for larger homes or users who require more sophisticated cleaning technology. If you prioritise high-performance cleaning and can justify the cost, the Saros 20 is the better option. However, for most users, the Qrevo S5V presents an excellent balance of features and value.
