Q Revo Curv 2 Flow Roller Mopping System

hands_on_demopositive

The Q Revo Curv 2 Flow utilizes a roller system for wiping, which is stated to remove dirt significantly better than classic pads without creating streaks or just spreading dirt around. This system ensures a more thorough and clean wiping process.

Q Revo Curv 2 Flow Fresh Water Supply

reviewer_claimpositive

The roller is continuously moistened with fresh water via eight nozzles, ensuring the robot always mops with clean water instead of already dirty water. This prevents cross-contamination and maintains cleaning effectiveness.

Q Revo Curv 2 Flow Roller Pressure

measurement_testpositive

The roller of the Q Revo Curv 2 Flow is 270mm wide, rotates at 220 RPM, and is pressed onto the floor with up to 15 Newtons (approximately 1.5 kg), which is significantly higher than many classic mopping pad systems and approaches manual wiping pressure.

Q Revo Curv 2 Flow Carpet Lifting and Protection

hands_on_demopositive

The robot automatically detects carpets with its sensors, lifting the mopping roller by up to 15mm and covering it with a 'Roller Shield.' This reliably prevents moisture or dirt from transferring to the carpet, although high-pile carpets must be under 13mm for reliable function.

Q Revo Curv 2 Flow Edge Cleaning

hands_on_demopositive

Using an Edge Adaptive System, the roller can be extended laterally to clean up to 10mm from edges, including walls, skirting boards, furniture, and chair legs. The reviewer notes it performs very well in these areas where many other robots leave more space.

Q Revo Curv 2 Flow Duo Divide Main Brush

The spiral-shaped Duo Divide main brush is designed to guide hairs to the center, where they are stripped off and vacuumed, significantly minimizing tangling. This is a huge advantage for households with pets or long human hair.

Saros 20 Adapti Lift Chassis Threshold Crossing

measurement_testpositive

The Saros 20's Adapti Lift Chassis 3.0 allows it to cross double thresholds up to 4.5 cm + 4.3 cm, totaling 8.8 cm, which the reviewer confirmed in testing. This reduces getting stuck at door transitions and other elevated edges.

Saros 20 Adaptive Carpet Lifting

hands_on_demopositive

The Saros 20's chassis can be raised up to 30mm with up to eight lift stages, automatically adjusting based on carpet height to ensure optimal brush pressure. This provides visibly better cleaning performance on high-pile carpets and transitions.

Saros 20 Starsight Autonomous System Navigation

The Starsight Autonomous System 2.0 combines Solid State Lidar, 3D ToF Sensor, and an RGB Camera, providing 21,600 sensor points and a high scanning rate for extremely precise orientation and 'fabulous' obstacle detection. It can identify up to 300 different obstacles, including small objects up to 2.2 cm high.

Saros 20 Flat Design

specification_claimpositive

With a height of approximately 7.98 cm, the Saros 20 is one of Roborock's thinnest models. This allows it to reach areas under sofas, beds, and sideboards, where dust and hair often accumulate but are inaccessible to taller robots.

Saros 20 Suction Power

measurement_testpositive

The Saros 20 offers a powerful 36,000 Pascal suction performance, described as a 'real challenge' that does not shy away from heavy dirt. This indicates strong cleaning capability for various types of debris.

Saros 20 Dual Brush System Hair Tangle Prevention

visual_inspectionpositive

The Saros 20 features a dual brush system where the main brush guides hairs to the center, and the side brush is designed to prevent tangling. This means less maintenance and consistently good performance for pet owners or those with long hair.

Saros 20 Flexi Arm Edge Cleaning

hands_on_demopositive

The Saros 20 uses extendable Flexi Arm elements for mopping, which can reach up to 2 cm deep into edges, corners, and skirting board areas. This ensures a reliable, edge-to-edge cleaning performance.

Saros 20 Rockdock Hot Water Mop Cleaning

hands_on_demopositive

The new Rockdock washes the mops with 100°C hot water, rinses them, and then dries them with warm air after each mopping cycle. The dock itself also cleans with hot water, effectively killing bacteria and reducing manual cleaning.

Saros 20 Automatic Mop Detachment

hands_on_demopositive

A key feature of the Saros 20 is its ability to automatically detach the mops before pure vacuuming runs or carpet cleaning, completely eliminating the risk of wetting carpets. The reviewer states this makes the risk of wet carpets "gleich null."

How effective is the Roborock Q Revo Curv 2 Flow at mopping floors?

The Q Revo Curv 2 Flow features a unique roller system that is continuously supplied with fresh water from eight nozzles, preventing the use of dirty water. This system effectively removes dirt and avoids leaving streaks, performing similarly to manual wiping with its 270mm wide roller and 1.5kg of pressure.

Can the Roborock Q Revo Curv 2 Flow clean carpets without wetting them?

The Q Revo Curv 2 Flow is designed to protect carpets. Its sensors detect carpeted areas, prompting the robot to automatically lift the mopping roller by up to 15mm and cover it with a "Roller Shield." This reliably prevents moisture and dirt from transferring to carpets, though high-pile carpets must be under 13mm for this feature to work optimally.

What is the Roborock Saros 20's capability for navigating over obstacles like thresholds and carpets?

The Saros 20 is equipped with an Adapti Lift Chassis 3.0, allowing it to navigate over challenging obstacles like double thresholds up to 8.8 cm high, confirmed by the reviewer's tests. It also features eight lift stages and a maximum 30mm lift when on carpets, ensuring optimal brush pressure for effective cleaning without getting stuck.

How intelligent is the Roborock Saros 20's navigation and obstacle avoidance?

The Saros 20 integrates Solid State Lidar, 3D ToF Sensor, and an RGB Camera into its Starsight Autonomous System 2.0. This combination provides 21,600 sensor points for highly precise orientation and "fabulous" obstacle detection, capable of identifying up to 300 different obstacles, including small items as low as 2.2 cm, though the reviewer still suggests removing very small objects for safety.

What is the suction power of the Roborock Saros 20 and how does it handle hair?

The Saros 20 boasts an impressive 36,000 Pascal suction power, which the reviewer describes as a "real challenge" to heavy dirt. Its dual brush system is specifically designed to guide hair to the center and prevent tangling on the side brush, resulting in less maintenance and consistently good performance for households with pets or long hair.

Does the Roborock Saros 20's dock offer advanced features for hygiene and convenience?

The Saros 20's new Rockdock significantly enhances hygiene and convenience. After mopping, it washes and rinses the mops with 100°C hot water and then hot-air dries them, killing bacteria and ensuring quick drying. The dock also cleans itself with hot water. Crucially, mops can be automatically detached before vacuum-only or carpet cleaning runs, completely eliminating the risk of wet carpets.

Which Roborock robot is better for thorough edge cleaning?

The Q Revo Curv 2 Flow utilizes an Edge Adaptive System where its roller extends laterally to clean within 10mm of edges. The Saros 20, on the other hand, employs extendable Flexi Arm elements that allow its mops to reach up to 2 cm deep into edges, corners, and skirting board areas, ensuring a reliable edge-to-edge cleaning. Both offer strong performance in this area, with slightly different approaches.
