Roborock Qrevo Slim vs Roborock Saros 10R

Introduction

The Roborock Qrevo Slim arrived on the market in 2024 as a proposal focused on discretion, with just 8.2 cm in height that allows it to slip under almost any piece of furniture. The Roborock Saros 10R, launched in 2025, represents the brand's technological evolution with substantial improvements in power and intelligent systems. Both belong to Roborock, the world's leading brand in robot vacuum cleaners, recognised for the reliability of its equipment and the quality of its mobile application.

The Qrevo Slim is designed for those who prioritise a compact robot that doesn't sacrifice essential functions such as mopping with rotating mops and a complete multifunction base. The more recent Saros 10R targets users seeking maximum suction power and the most advanced technologies in navigation and artificial intelligence, with notable improvements in every technical aspect.

Power and Suction

The most evident difference between these two Roborock models lies in raw power. The Saros 10R delivers 18,500 Pa of suction, a figure that places it amongst the most powerful robots on the current market. The Qrevo Slim offers 11,000 Pa, more than sufficient power for most homes but clearly inferior. This difference is especially noticeable on medium or long pile carpets, where the Saros 10R can extract more embedded dirt.

Both feature Roborock's DuoDivide main brush, specifically designed to prevent hair tangles. This system pushes hairs towards the central suction gap, which is particularly useful in homes with pets. Both models can lift the main brush during mopping, preventing it from getting unnecessarily wet.

Regarding the side brush, both have an extendable system to improve cleaning in corners. However, the Saros 10R adds two advantages: it can lift the side brush during mopping (preventing dirty water splashes) and also incorporates anti-tangle technology in this component. The Qrevo Slim doesn't lift its side brush nor includes this anti-tangle protection, which may require somewhat more manual maintenance.

Mopping

Both robots mop with two rotating mops that can also extend to better reach edges and skirting boards. Both detect dirt on the mops themselves as well as on the floor, allowing automatic re-scrubbing when necessary. The bases of both models wash the mops with hot water and dry them with hot air, guaranteeing hygiene and preventing bad odours.

The Saros 10R marks important differences in several aspects. Firstly, it mops the floor with warm water thanks to an internal system that heats the water before applying it, whilst the Qrevo Slim uses cold water. This improves the dissolution of grease and adhered dirt. Secondly, the Saros 10R's mops can lift between 12 and 22 mm, adapting better to carpets of different thicknesses, compared to the Qrevo Slim's fixed 10 mm.

An exclusive function of the 2025 model is the automatic detachment of mops at the base. When you only want to vacuum without mopping, the Saros 10R can leave the mops at the station and go out solely to vacuum, without needing you to remove them manually. The Qrevo Slim doesn't have this option, although it can lift its mops sufficiently so they barely touch the floor during vacuuming.

The Saros 10R includes a detergent tank in its base, something the Qrevo Slim doesn't offer. This allows the base to automatically dispense cleaning product during mop washing, improving system hygiene without manual intervention.

Navigation System

Here we find another substantial difference. The Qrevo Slim features the StarSight 1.0 system, which already includes dual camera with artificial intelligence, front 3D laser sensor, LED for night vision and the ability to recognise 73 different types of obstacles. It can identify pets and allows remote access to the camera from the app.

The Saros 10R evolves to StarSight 2.0, maintaining the same base technologies but expanding recognition to 108 obstacles. This improvement translates into more precise navigation and fewer manual interventions to free the robot from compromising situations. Additionally, it incorporates SmartPlan 2.0 compared to the Qrevo Slim's SmartPlan 1.0, which means more efficient route planning and optimised cleaning times.

The Saros 10R adds stain recognition using artificial intelligence, a function the Qrevo Slim doesn't have. This allows the robot to visually identify particularly dirty areas and automatically apply more intensive cleaning in those specific spots.

Autonomy and Battery

The Saros 10R features a 6,400 mAh battery, clearly superior to the Qrevo Slim's 5,200 mAh. However, both declare 180 minutes of autonomy. This apparent contradiction is explained because the Saros 10R, with greater suction power and more advanced systems, consumes more energy during operation. In the end, both offer the same effective autonomy, sufficient for medium-large sized homes in a single charge.

The Saros 10R's greater battery capacity may be noticeable in particularly demanding cleaning sessions, such as vacuuming in maximum mode on thick carpets, where consumption soars. In those situations, the 2025 model can maintain performance for longer before needing to return to the base.

Intelligent Functions

Both robots can overcome obstacles, but with important differences. The Qrevo Slim overcomes steps of up to 20 mm. The Saros 10R goes further with its "Single step 4 mm - Double step 22 mm" system, which allows it to navigate more complex level changes, such as transitions between rooms with different floor types or small double steps.

Both models include Roborock's own voice assistant and are compatible with Alexa and Google Home, allowing complete voice control of their functions.

Multifunction Cleaning Base

Both bases are complete multifunction units: they auto-empty the robot's dust container, wash the mops with hot water and dry them with hot air. Both have a self-cleaning system for the tray where the mops are washed, although the Saros 10R features version 2.0 of this system, presumably more efficient than the Qrevo Slim's 1.0.

The capacity of the tanks is very similar. The Qrevo Slim has a 2.7-litre dust bag compared to the Saros 10R's 2.5 litres. Both feature a 4-litre clean water tank; the Qrevo Slim offers 3.5 litres of dirty water compared to the more recent model's 3 litres. These differences are minimal in daily practice.

As already mentioned, only the Saros 10R includes a detergent tank, an advantage for those seeking maximum automation of the mopping process. Neither offers connection to water pipes, nor do they have an optional kit available for this.

Dimensions

The diameter is identical in both: 35.3 cm. The height marks a small difference in favour of the Saros 10R, which at 7.98 cm is 2.2 mm lower than the Qrevo Slim's 8.2 cm. It may seem insignificant, but with very tight-fitting furniture those millimetres can make the difference between the robot passing through or not.

The bases have different dimensions. The Qrevo Slim's measures 34 cm wide, 52.1 cm high and 48.7 cm deep. The Saros 10R's is somewhat wider (38.1 cm) but lower (48.8 cm) and less deep (47.5 cm). In practice, the Saros 10R's base occupies a slightly more compact space in height, which can facilitate its placement under shelves or low furniture.

Real-world user experience

For large homes, the Saros 10R offers clear advantages: greater power to clean faster, better navigation that reduces total cleaning time and a more generous battery that holds up better in long sessions. The Qrevo Slim performs perfectly in medium-sized flats, where its 11,000 Pa and 180 minutes of autonomy are more than sufficient.

If you live with pets, both are excellent options thanks to the DuoDivide anti-tangle brush. The Saros 10R adds additional protection with its also anti-tangle side brush and greater power to extract embedded hair from carpets. The Qrevo Slim will require somewhat more manual attention on the side brush, but nothing concerning.

In homes with carpets, the Saros 10R stands out for its greater mop lift (up to 22 mm), its ability to automatically detach the mops for vacuum-only sessions and, above all, for those 18,500 Pa that make a difference on medium and long pile carpets. The Qrevo Slim works well on thin carpets and hard floors, but may fall somewhat short on demanding carpets.

For those seeking maximum automation, the Saros 10R wins by including a detergent tank, automatic mop detachment and better tray self-cleaning system. The Qrevo Slim requires somewhat more manual intervention in these aspects, although it remains very convenient to maintain.

Conclusion: Which to choose?
