As consumers become more accustomed to the convenience offered by robotic cleaners, the demand shifts towards devices that can handle more challenging environments and deliver superior cleaning results. Roborock’s decision to concentrate on suction, obstacle negotiation, and deep cleaning capabilities directly addresses these escalating expectations.
Design and Technological Advancements: A Sleeker, Smarter Machine
Building upon the successful dual-flagship strategy of its previous generation, the Saros 10 and Saros 10R, Roborock has streamlined its offering with a single, unified model in the Saros 20. This consolidation signifies a refinement of design and functionality, integrating the best aspects of both previous models into one cohesive unit. The Saros 20 draws significant inspiration from the Saros 10R, notably by replacing the traditional raised LiDAR dome with the innovative StarSight Autonomous System 2.0. This advanced system utilizes front-facing 3D Time-of-Flight (ToF) sensors, enabling precise mapping and navigation of its surroundings without the need for a protruding sensor.
This design evolution results in a remarkably low profile for the Saros 20, standing at just 79.8mm tall. This reduced height allows the robot to effortlessly glide beneath low-lying furniture such as sofas, sideboards, and coffee tables – areas often overlooked by less agile cleaning devices. While the Saros 10 could achieve similar clearance by retracting its LiDAR sensor, the Saros 20’s integrated, dome-less design inherently possesses fewer moving parts, contributing to enhanced durability and reliability. During extensive testing, the navigation capabilities of the Saros 20 proved to be consistently dependable, demonstrating the effectiveness of the StarSight system.
Complementing its advanced navigation, the Saros 20 incorporates front-mounted cameras that are instrumental in its ability to recognize and actively avoid common household obstacles. This intelligent object recognition significantly reduces the likelihood of the robot becoming entangled with cables, shoes, or other items, thereby minimizing user intervention and ensuring a smoother cleaning operation.
Beneath its sleek exterior, the Saros 20 features a sophisticated dual rotating microfibre mop pad system. One of these mop pads is equipped with Roborock’s signature FlexiArm system. This innovative extension allows the mop pad to reach beyond the robot’s main body, enabling it to effectively clean along cupboard edges and under overhangs, ensuring comprehensive coverage even in challenging nooks and crannies.
The main cleaning brush of the Saros 20 has also undergone a significant redesign. The split DuoDivide main brush is engineered to channel hair towards its central opening, where it can be efficiently drawn into the dustbin, substantially reducing the common issue of hair wrapping around the brush roller. Furthermore, a secondary FlexiArm system powers the side brush, granting it the agility to sweep along wall edges and into tight corners, thereby capturing dust and debris that might otherwise be missed.
AdaptiLift Chassis 3.0: Conquering Varied Terrains
Perhaps the most significant mechanical upgrade in the Saros 20 is the introduction of the AdaptiLift Chassis 3.0. This advanced system goes beyond merely raising the robot’s body by adjusting its main wheels; it incorporates additional, deployable legs that provide an extra increment of vertical clearance. This enhanced capability allows the Saros 20 to overcome a two-stage threshold measuring up to an impressive 8.7cm. This is achieved through a first step of 4.5cm followed by a second step of 4.3cm. While this may not be sufficient to surmount every architectural barrier – for instance, a particularly large step encountered in older Victorian homes might still pose a challenge – it represents a substantial leap in obstacle-climbing ability compared to many competing robotic vacuums. This capability is particularly beneficial in homes with varied floor heights or multiple levels.
The AdaptiLift system also plays a crucial role in the Saros 20’s adeptness at cleaning carpets. It enables the robot to handle carpets with a pile height of up to 3cm, ensuring that it can effectively vacuum even thicker rug materials without becoming bogged down.
The Saros 20’s floor management capabilities are equally impressive in their flexibility. In vacuum-only mode, the robot can intelligently leave its mop pads at the docking station, preventing unnecessary wear and tear. When engaged in mopping, it has the ability to lift its main brush roller to prevent any collected dust from inadvertently smearing or staining the cleaned floor.
A key feature for homes with mixed flooring is the Saros 20’s intelligent response to carpet detection. Upon identifying a carpeted surface, the robot can automatically retract its mop pads. If further obstacle negotiation is required, it can also engage the AdaptiLift chassis to raise its body, allowing it to transition seamlessly from hard floors to carpets and rugs without manual intervention. This adaptive behaviour makes the Saros 20 exceptionally well-suited for environments that feature a combination of hard surfaces, carpets, and area rugs.
The Roborock Dock: Comprehensive Cleaning and Maintenance
The accompanying Roborock Dock is an integral component of the Saros 20’s advanced cleaning ecosystem, handling both dust emptying and mop maintenance with sophisticated automation. The dock features a heated mop washing system that utilizes water heated to 100°C, providing a deep and hygienic clean for the mop pads. A separate tank is provided for cleaning solution, although none is included with the base package, offering users the flexibility to choose their preferred cleaning agent.
Following the wash cycle, the dock employs 55°C air drying to thoroughly dry the mop pads, preventing the development of mildew and unpleasant odours. The dustbin on the robot is automatically emptied into a replaceable dust bag within the dock, which boasts an impressive capacity to hold up to 65 days of dirt. For user convenience, the dock is supplied with a spare dust bag and two additional mop cloths, ensuring that users are well-equipped for extended periods of operation.
The Roborock App: Intuitive Control and Intelligent Mapping
The Roborock app continues to be a standout feature, offering a powerful and intuitive interface for controlling the Saros 20. The initial mapping process is remarkably swift, typically taking only a few minutes to generate a comprehensive map of the home. The app automatically partitions the mapped area into distinct rooms and can even identify and label furniture based on the robot’s camera input.
Users have granular control over the mapped environment. Rooms can be easily split or merged to accurately reflect the home’s layout. Furthermore, users can manually add furniture, define thresholds, establish no-go zones to prevent the robot from entering certain areas, and designate pet-specific zones. The ability to recognize furniture also serves as a useful cleaning shortcut, allowing users to easily target specific areas, such as the space around a dining table, for focused cleaning.
Cleaning operations can be initiated for the entire map, selected rooms, or a specific zone. The AI SmartPlan feature offers an automated approach, intelligently selecting optimal cleaning settings. Alternatively, users can manually choose from various cleaning modes, including vacuuming and mopping, mopping only, vacuuming only, or a combined vacuuming and mopping sequence.
The Saros 20 offers four standard suction settings, complemented by a MAX+ mode for vacuum-only operations, providing ample power for various cleaning needs. The mop water flow can be adjusted across 30 levels, a level of granularity that may feel excessive to some users, as discerning significant differences between adjacent settings might prove challenging.
Most cleaning modes support one or two passes and offer three distinct routing options, allowing for customized cleaning strategies. The routines feature further enhances control, enabling users to combine different settings for individual rooms, creating tailored cleaning plans for each area of the home. Advanced settings provide deeper customization, including options for automatic re-mopping, stain detection, and closer cleaning beneath furniture or into corners. The Saros 20 also possesses the intelligence to return to areas that were previously blocked by people or pets, ensuring that no spot is missed.
Unrivaled Performance: Power and Precision in Action
The Saros 20 sets a new benchmark for suction power in the robotic vacuum market, boasting a claimed 36,000Pa. This extraordinary level of suction translates directly into exceptional cleaning performance. During rigorous testing on a heavily soiled test rug, two passes at maximum power with carpet boost engaged successfully removed all traces of flour, delivering results comparable to a high-powered handheld vacuum cleaner.
On hard flooring, the Saros 20 demonstrated equal efficacy, effortlessly collecting dust from the center of a room without leaving any residue. Edge cleaning performance was rated as good, with the robot collecting the majority of dust along walls, with any minor remnants being effectively picked up during the mopping cycle, resulting in an excellent overall finish.
The mopping functionality, enhanced by re-mopping and stain detection features, proved highly effective. The robot intelligently adjusted its route and performed multiple passes over marked stain areas. The ability to raise its front wheel to increase pressure through the rear mop pads further contributes to its deep cleaning capabilities. Coffee and red wine stains were successfully removed after a single mopping pass. Loose dirt from a mud test was vacuumed away before the remaining stain was efficiently tackled by the mop.
Ketchup, a notoriously difficult stain, presented a more significant challenge. The initial mopping pass dramatically reduced the stain, and two subsequent runs removed almost all of the remaining mark. A final pass completed the task, although pre-soaking the stain with kitchen cleaner aided the process. While the Narwal Flow demonstrated slightly superior performance in this specific stain removal test, the Saros 20 maintained an advantage in overall vacuuming and edge cleaning capabilities.
Navigation throughout testing was consistently excellent. The Saros 20 adeptly avoided cables, shoes, and simulated pet waste. Its adaptive lifting chassis proved invaluable in successfully traversing the sled feet beneath desks without becoming immobilized. Furthermore, the robot operates at a relatively quiet 58dB, making it unobtrusive enough for use in the same room as occupants.
Battery life is rated at 200 minutes on its lowest setting. Even when employing stronger suction settings and performing multiple vacuuming and mopping passes, the Saros 20 consistently provided ample power for comprehensive spot-cleaning tasks.
