Introduction
The Dreame X60 Pro Ultra and the Roborock Saros 20 Sonic represent two high-end propositions within the robot vacuum market with multifunction base stations. Both units arrived on the market in 2026, with the Roborock launched in March and the Dreame in May, and they share a similar philosophy: offering complete cleaning autonomy through base stations that not only empty the dust but also wash and dry the mops with hot water.
We're looking at two models designed for users seeking to completely delegate vacuuming and mopping tasks. The Dreame robot vacuum opts for raw power and generous robotic extensions, whilst the Roborock robot vacuum relies on its reputation for reliability and a state-of-the-art vibratory mopping system. The choice between one and the other will depend on the specific priorities of each household.
Power and Suction
The difference in suction power is notable. The Dreame X60 Pro Ultra delivers 42,000 Pa, a figure that places it at the top of the segment, whilst the Roborock Saros 20 Sonic offers 36,000 Pa. In practice, this can translate into a greater capacity for the Dreame to extract ingrained dirt from carpets or pick up heavier particles.
The main brushing system marks another important difference. The Dreame features a dual HyperStream 2.0 brush designed to prevent hair tangles, with two elements anchored at one end that facilitate cleaning. The Roborock mounts the DuoDivide system, which pushes hairs towards the central gap for direct suction. Both are anti-tangle systems, but with different philosophies: one divides the work between two independent brushes, the other channels everything towards the centre.
As for the side brush, both models lift it during mopping and feature anti-tangle design. The difference lies in the extension: the Dreame deploys its side brush up to 12 cm using a robotic system, which allows better reach into corners. The Roborock also has extension, although the exact distance isn't specified. Additionally, the Dreame incorporates a specific brush for skirting boards, a function the Roborock doesn't include and which can make a difference in cleaning the edges where more dust accumulates.
Mopping
Here we find one of the most significant differences in this robot vacuum comparison. The Dreame X60 Pro Ultra uses two rotating mops that spin at 280 RPM with 15N of pressure, whilst the Roborock Saros 20 Sonic opts for the VibraRise 5.0 system, a vibratory mop with 14N of pressure. These are two different approaches: the Dreame's rotating mops cover more surface area and scrub in a circular motion, whilst the Roborock's vibratory system generates rapid back-and-forth movements.
The mop extension also favours the Dreame, with 18 cm of robotic reach that allows mopping very close to skirting boards. The Roborock also extends its mops, although without specific figures. In terms of lifting, the Dreame stands out again with 21.5 mm, sufficient to pass over thick carpets without wetting them. The Roborock reaches between 8 and 18 mm, a tighter figure that may limit its use in homes with high-pile carpets.
Both mop the floor with hot water: the Dreame at 40°C and the Roborock with warm water (without exact temperature specified). Both detect dirt on both the mops and the floor to adjust mopping, and both allow the mops to be removed at the base station when you only want to vacuum.
Navigation System
Both the Dreame X60 Pro Ultra and the Roborock Saros 20 Sonic integrate retractable 360° LIDAR, which guarantees precise mapping and efficient navigation. Both incorporate dual RGB cameras with artificial intelligence, front 3D laser sensor, pet recognition, curtain detection, remote camera access and LED for night vision.
The difference lies in obstacle recognition capacity: the Dreame identifies up to 320 different objects, whilst the Roborock reaches 300. Additionally, the Dreame includes proactive lighting in its obstacle avoidance system, a function that improves detection in low-light conditions.
Regarding intelligent cleaning, the Dreame uses CleanGenius 3.0 and the Roborock SmartPlan 3.0. Both systems adjust routes and cleaning modes according to floor type and detected dirt.
Autonomy and Battery
Both units mount 6,400 mAh batteries, which guarantees sufficient autonomy for large homes. The advantage of the Dreame X60 Pro Ultra lies in its Power Master system, which takes advantage of the time the robot is at the base station washing the mops to recharge the battery. In just 5 minutes it recovers 24% charge, which significantly reduces downtime in large homes. The Roborock doesn't specify autonomy data or charging times.
Smart Functions
The Dreame X60 Pro Ultra can overcome single steps of up to 50 mm and double steps of 100 mm, figures that exceed the Roborock Saros 20 Sonic's 45 mm and 88 mm. This capability is especially useful in homes with level differences between rooms or small steps on terraces.
Both robots include their own voice assistant and compatibility with Alexa and Google Home, which facilitates control through voice commands without needing to open the app.
Multifunction Cleaning Base Station
Both base stations share essential functions: auto-emptying of the dust container, washing mops with hot water at 100°C, drying with hot air and self-cleaning of the washing tray also at 100°C. Both include a detergent tank and allow the mops to be automatically removed when you only want to vacuum.
The differences appear in the details. The Dreame dries the mops with air at 50°C, whilst the Roborock reaches 55°C, which may slightly speed up the process. The Dreame's dust bag has a capacity of 3.2 litres compared to the Roborock's 2.5 litres, which means fewer bag changes throughout the year.
As for the water tanks, the Dreame incorporates 4.2 litres of clean water and 3 litres of dirty water; the Roborock has 4 litres of clean water and 3 litres of dirty water. Minimal differences that barely affect mopping autonomy. The Dreame offers an optional plumbing connection kit that's purchased separately, an option the Roborock doesn't contemplate.
Dimensions
The Dreame X60 Pro Ultra measures 350 mm in diameter and 79.5 mm in height, whilst the Roborock Saros 20 Sonic reaches 353 mm in diameter and 79.8 mm in height. Minimal differences that barely influence the ability to pass under furniture, although the Dreame wins by tenths in both areas.
The Roborock specifies its base station measurements: 409 mm wide, 470 mm high and 440 mm deep. The Dreame doesn't provide these details, which makes it difficult to assess the space it will occupy in the home.
Real-World User Experience
For large homes, the Dreame X60 Pro Ultra offers clear advantages thanks to its Power Master system, which recharges whilst washing the mops, and its larger dust bag capacity. The 42,000 Pa power is also decisive if there are thick carpets or pets that shed a lot of hair, especially with the dual HyperStream 2.0 brush designed to prevent tangles.
The Roborock Saros 20 Sonic excels in mopping thanks to its VibraRise 5.0 vibratory system, which may be more effective on stubborn stains, and in drying mops with air at 55°C. Its reputation for reliability and the quality of its app are compelling arguments for those who prioritise system stability over more aggressive technical specifications.
In homes with many level changes or high thresholds, the Dreame overcomes obstacles of up to 50 mm compared to the Roborock's 45 mm, which can prevent the robot from getting stuck. The Dreame's 18 cm robotic extension on the mops also makes a difference in homes with many corners and tricky nooks.
Conclusion: Which to Choose?
Choose the Dreame X60 Pro Ultra if… you're looking for maximum suction power and have a large home with carpets. Its Power Master system reduces downtime, the 3.2-litre dust bag requires less maintenance, and the ability to overcome steps of up to 50 mm makes it more versatile in homes with level changes. The 18 cm robotic extensions on the mops and 12 cm on the side brush guarantee more thorough cleaning of edges and corners. If you have pets, the dual HyperStream 2.0 brush and the specific skirting board brush can make the difference.
Choose the Roborock Saros 20 Sonic if… you prefer Roborock's proven reliability and a vibratory mopping system that may be more effective on difficult stains. The 55°C drying speeds up the process and reduces the risk of bad odours. Although its 36,000 Pa power is lower than the Dreame, it's still more than sufficient for most homes. If you value software stability and a polished app, Roborock has a solid track record in this regard. It's a balanced option for those seeking a better robot vacuum without needing extreme specifications.
