Roborock Saros 20

Introduction

The Roborock Saros 20 arrives on the market in February 2026 as a premium range robot vacuum and mop that brings together the best of current home cleaning technology. With 36,000 Pa of suction power and a StarSight 2.0 navigation system equipped with dual AI camera, this model represents Roborock's commitment to an intelligent vacuum capable of adapting to the real needs of each home.

Power and Cleaning System

The 36,000 Pa power places the Roborock Saros 20 amongst the most powerful robots on the market, which translates into particularly effective suction capacity on carpets and for capturing fine particles. The DuoDivide Anti-Tangle main brush is particularly interesting for homes with pets, as its design pushes hair towards the central suction gap preventing it from wrapping around the roller. Additionally, this brush can be raised when the robot detects carpets or when it's not necessary, optimising cleaning according to the surface type.

The side brush incorporates two features that make a difference: it's extendable to better reach corners, and features an anti-tangle system that reduces manual maintenance. In practice, this means less time spent untangling hair from the brush and more complete coverage at the edges of rooms. The 6,400 mAh battery provides sufficient autonomy for considerably sized homes, although the manufacturer doesn't specify the exact minutes of operation.

Mopping System

The Saros 20's mopping system uses two rotating mops that spin at 200 RPM with 13N pressure, which guarantees effective mopping even on stubborn stains. The mops can extend to reach edges and lift between 12 and 22 mm, allowing the robot to move from hard floors to carpets without wetting them. Typically, this lift is sufficient for medium thickness carpets, although very thick ones may require setting no-mop zones.

A notable feature is the use of warm water for mopping the floor, which improves the dissolution of greasy dirt compared to cold water. The robot incorporates dirt detection both on the mops and on the floor, automatically adjusting the mopping intensity and necessary passes. When it returns to the base, the mops are automatically removed for washing with hot water at 100°C, a process that eliminates bacteria and organic residue far more effectively than cold water. Subsequently they're dried with hot air at 55°C, preventing bad odours and microorganism proliferation.

Navigation and Intelligence

The StarSight 2.0 system combines dual AI camera with front 3D laser sensor, creating precise three-dimensional mapping of the home. This configuration allows the robot to recognise up to 300 different types of obstacles, from cables and slippers to small toys or pet excrement. Pet recognition and curtain detection add additional layers of intelligence that avoid problematic situations during cleaning.

The SmartPlan 3.0 technology analyses room type, dirt level and obstacles to create optimised cleaning routes. AI stain recognition makes the robot automatically intensify cleaning in areas that require it. Remote camera access and night vision LEDs even allow using the robot as a basic surveillance system when you're not at home, a function that some users find especially useful for monitoring pets.

Autonomy and Practical Use

With a 6,400 mAh battery, the Saros 20 is prepared to clean large homes in a single session. The 270 ml dust bin is adequate for daily use, although the base will handle automatic emptying into a 2.5 litre bag. The robot's water tank has a capacity of 69 ml, sufficient because the unit returns periodically to the base during mopping to refill water and wash the mops.

The ability to overcome single steps of up to 45 mm and double ones of up to 88 mm is exceptional. In practice, this means the robot can climb onto thick carpets without problems, cross sliding door guides and navigate small level changes that would stop less capable models. At 79.8 mm in height and 353 mm in diameter, it can slide under most standard furniture.

Base and Maintenance

The Roborock Saros 20's multifunction base measures 381 mm wide, 488 mm high and 475 mm deep, dimensions worth considering when finding its location. It integrates 4 litre tanks for clean water and 3 litres for dirty water, plus a detergent compartment that's automatically dispensed during mop washing.

Auto-emptying of the dust bin into a 2.5 litre bag reduces maintenance frequency to once every month or month and a half, depending on the home's dirt level. Self-cleaning of the washing tray with water at 100°C keeps the base hygienic without manual intervention. Ultimately, the user barely needs to refill the clean water tank from time to time and empty the dirty water one, tasks that the app itself will remind you about when necessary.

Conclusion

The Roborock Saros 20 is designed for users seeking a high-end robot vacuum and mop with minimal maintenance. It's especially recommended for homes with pets thanks to its anti-tangle system, and for large homes due to its battery capacity and obstacle-overcoming ability. The combination of power, advanced artificial intelligence and completely autonomous base makes it a comprehensive cleaning solution for those who value convenience and professional results.
