Roborock Saros 10R review: The StarSight vacuum robot is super flat and really good
Stargazing.
The Saros 10R is Roborock's new flagship with rotating mops. The 7.98-cm-thin model has lots of other exciting highlights to offer, such as the StarSight System 2.0. Our review of the Roborock Saros 10R will reveal whether the vacuum and mopping robot also reaches for the stars in practice.Marcus Schwarten, 👁 Marcus Schwarten (translated by Daisy Dickson) Published 🇩🇪 🇫🇷 ...
Roborock Saros 10R verdict: Different, but just as good
The Roborock Saros 10R is an extremely well-equipped robot vacuum that's packed with numerous features. Thanks to its unique features, it boasted strengths during our test that set it apart from the Saros 10—and suffered only a few weaknesses.
For example, the Roborock Saros 10R's obstacle detection worked really well during our test thanks to its innovative StarSight system, albeit with minor limitations when it came to navigation. Its mopping function showed some slight weaknesses—at least in the endurance test—but managed to clean along edges well.
The Roborock Saros 10R impressed us with its ultra-flat design—without it needing to retract a laser tower—and with its climbing function. Overall, it performed very well during our test and didn't have to hide behind its sister model, the Roborock Saros 10, or the competitor's flagship Dreame X50 Ultra Complete. However, this scope of performance comes at a high price of almost $1,600.

Roborock has started the year 2025 with two brand-new flagship vacuum robots. After we recently reviewed the Roborock Saros 10 and found it to be very good, it's now the Roborock Saros 10R's turn to prove itself to us. Does the robot vacuum, which is a little cheaper, perform worse with its various differences? Or can it even beat the Saros 10? Our Roborock Saros 10R test report will reveal the answer.

Connectivity: StarSight 2.0 and rotating mops
The Saros 10R relies on the StarSight 2.0 system meaning it detects obstacles and navigates the building using ToF sensors in the front and rear as opposed to the usual top-mounted LiDAR tower. StarSight 2.0 is a new version of the Starsight 1.0 tech introduced in 2024 with the release of the Roborock Qrevo Slim; in the meantime, the Saros 10, a close relative of the 10R has a retractable LiDAR sensor tower (that Roborock refers to as RetractSense). The Saros 10 was announced in January 2025 during CES; at the time, no other robot vacuum had a retractable sensor tower.
Back to the 10R. In addition to StarSight 2.0, it also sports the new VertiBeam side-mounted obstacle avoidance system for navigating particularly close to objects that seems to work well, from our experience.
The Roborock Saros 10R is particularly flat at 7.98 cm thanks to its autonomous StarSight System 2.0 whereas the Saros 10 has to retract its laser tower whenever it needs to go under your bed or a similar object to become just as compact. This makes it possible to clean under more furniture, which now only needs to have a ground clearance of 8 cm.
Thanks to its AdaptiLift case, the new top-of-the-range model can reach more areas, as it can overcome obstacles of up to 4 cm (in two stages). During our test, it successfully overcame a single-stage obstacle of 30 mm, thus fulfilling the manufacturer's promise. In addition, the robot can lift itself up to 1 cm when vacuuming long-pile carpets to protect them. So the Saros 10 combines the 2024 innovations from the very slim Qrevo Slim and the round Qrevo Curv.
Another strength is its increased suction power of 20,000 Pa. Its FlexiArm side brush can be raised and extended, as can one of the two rotating mops under the rear of the robot. The Saros 10R can additionally raise its main brush, which is based on the modern Dual Anti-Tangle system with two sections.
Unfortunately, the Roborock Saros 10R's scope of delivery is just as basic as its sister model without the "R". In addition to a second dust bag, only a quick start guide is included. Even a bottle of detergent, which the 10-in-1 multifunctional docking station 4.0 can dispense for the robot and mop washing at temperatures of up to 80 °C, is unfortunately not included.
Other functions include vacuuming the robot, drying the mop using hot air at up to 55 °C, and self-cleaning the removable tray. However, the stylish high-gloss front is not only highly reflective, but also attracts fingerprints quite badly and magically attracts dust. In addition, the 4 and 3 liter water tanks aren't stowed away behind a flap and Roborock unfortunately hasn't included a cable winder at the back.
Impressions of the Roborock Saros 10R
Setup and app: Familiar and excellent fare
We won't go into detail about the Roborock app again here, so please refer to our previous test report.
Its app is one of the best on the market, was easy to set up during our practical test, and offers countless setting options for cleaning performance, map management, the robot itself and its cleaning station. In addition to networking with Matter, the Saros 10R also has its own voice assistant called "Hello Rocky". The microphones are located around the two physical buttons on the top of the device.
Navigation and obstacle detection: Brilliant obstacle detection
The StarSight System 2.0 enables particularly precise scanning of the robot's surroundings using 3D time-of-flight instead of 2D detection with the standard LDS. Its scanning frequency is over 20 times higher, which had a positive effect on obstacle detection during our test of the Roborock Saros 10R.
While LiDAR models such as the Saros 10 usually fail with very small obstacles, the Saros 10R even detected and successfully avoided a single 4x2 brick measuring approx. 3 x 1 cm. The system also successfully detected all other obstacles in our test, including socks, cables and more. Only a single shoelace lying flat on the floor—the final opponent in all robot vacuum tests to date—was the Saros 10's undoing too.
The strength of StarSight's obstacle detection led to minimal deductions in the robot's actual navigation. The Roborock Saros 10R navigated reliably and systematically through its surroundings during our test. However, it occasionally turned on its own axis to reorient itself. This is because the StarSight system only "looks" in two directions and not 360 degrees, as is the case with LiDAR.
This leads to a slightly longer cleaning process. Still, the difference is only a few minutes and is negligible unless a visitor is at your door and it has to be done particularly quickly.
Cleaning performance: Slight deductions when mopping
The Saros 10R delivered good cleaning performance on smooth surfaces in our practical test. Surfaces were cleaned thoroughly, especially when "clean in mixed pattern" was activated in the settings under the menu item "cleaning pattern". The robot then moves through the house or apartment rotated by 90 degrees to the last cleaning direction.
As with the Saros 10, its corner cleaning proved to be a positive feature. To do this, the robot reliably extended its FlexiArm side brush and swept most of the sand from the corners during our practical test.
Its cleaning performance on carpets was good, but not perfect. Thanks to its high suction power, the robot vacuum picked up most of the dirt from the test carpets. However, as Roborock has decided to switch off and retract the side brush when cleaning carpets, it cannot "rummage through" the carpet. This means that more dirt is left behind than necessary, especially if the carpet reaches up to a wall or obstacle. On the other hand, this procedure protects the floor covering.
The anti-hair entanglement technology and the two-part main brush worked reliably in our test.
For mopping, the Saros 10R uses two rotating mops, which we know from many of the manufacturer's Qrevo models or from Dreame's current flagship X50 Ultra Complete. These can be both lifted and, more recently, lowered for carpet cleaning. The mop on the right when viewed from behind can also be extended to the side, allowing not only borderless cleaning, but even wiping just below furniture in the case of slightly overhanging obstacles such as furniture doors. During our test, the Saros 10R therefore managed better edge cleaning than the Saros 10.
With light soiling, the Saros 10R did well when mopping tiles and other smooth surfaces. The only thing that detracted from its overall picture was the traces of the two rotating mops that remained and were visible in certain lighting conditions.
The robot can automatically detect and dynamically rework heavier soiling, which worked well in practice. In one of our endurance tests—which consisted of a splash of ketchup that had dried up for a few hours—the two mops didn't work as thoroughly as the VibraRise 4.0 mopping system in the Roborock Saros 10 or even the rotating mop roller of the Ecovacs Deebot X8 Pro Omni.
Even after cleaning twice, more ketchup remained on the floor and the surface was also a little sticky after cleaning, as the mops spread the ketchup more than the vibrating mop cloth. However, cleaning the mops in the station after the ketchup test worked well.
Battery life and power consumption: Shorter runtimes
In terms of battery life, the Roborock Saros 10R clearly lags behind its sister model. In the endurance test, it only covered 85 square meters on one charge of the 6,400 mAh battery before returning to the charging station for around 2:20 hours with 14 percent charge remaining. If it interrupts a cleaning process due to a lack of battery power, it only charges up again until it can complete the task.
In our 24-hour test, its power consumption was also slightly higher than that of the Saros 10. In this test, the robot had to process a good 75 square meters of smooth flooring and smaller runners with standard suction power, a medium amount of water and a single standard cleaning. This was followed by the usual cleaning program in the station and waiting for the next use (with a standby consumption of approx. 5 watts). After 24 hours, the meter showed just under 0.45 kWh. This results in a monthly power consumption of around 13 kWh if the robot vacuum and mop is to clean around 75 square meters a day.
The Roborock Saros 10R was slightly quieter than the Saros 10 when measuring its noise level (from a distance of 1 m): around 60 dB in maximum suction mode and around 56 dB in standard mode. The station also emits a good 70 dB when vacuuming and hisses relatively quietly for a few hours when drying the mops (depending on the setting in the app).
Roborock Saros 10R test summary: Other strengths than the Saros 10
The Roborock Saros 10R did almost everything well during our test. Its obstacle detection is particularly impressive, while there are slight deductions for its navigation and mopping performance.
