Introduction
We're looking at two Roborock models that share a surname but belong to different generations. The Qrevo Edge S5A arrived on the market in 2024 as a high-end device with advanced features, whilst the Qrevo S Pro was introduced in April 2026 as a more simplified alternative within the same family. Both devices include a multifunction base capable of washing and drying the mops with hot water and air, which guarantees effective mopping in homes where this task is a priority.
The suction power is identical in both: 18,500 Pa, sufficient for medium-pile carpets and hard floors. They also share a 5,200 mAh battery and 180-minute runtime, which makes them suitable for considerably sized homes. The differences appear in details that can make a difference to the daily user experience, especially in the brushing system and detection capabilities during mopping.
Power and Suction
The 18,500 Pa of power is shared, so pure suction performance doesn't make a difference. What does change radically is the main brushing system. The Qrevo Edge S5A incorporates Roborock's DuoDivide anti-tangle brush, designed to push hairs towards the central suction gap and minimise tangles. This is especially useful in homes with pets or people with long hair.
The Qrevo S Pro, on the other hand, features a traditional single brush. Whilst functional, it doesn't offer the same resistance to tangles and will require more manual maintenance if you live with animals.
Another important difference is in the side brush. The Edge S5A has an extendable side brush, which allows better sweeping of corners by projecting beyond the robot's diameter. The S Pro doesn't have this function, so perimeter sweeping will be less effective. Both models include an anti-tangle side brush, which helps reduce maintenance on this component.
Neither model lifts the main brush or side brush during mopping, so both keep sweeping active even when mopping.
Mopping
This is where the differences become most evident. Both robots use two rotating mops and lift the mops 10 mm when they detect carpets or need to avoid wetting them. They also mop with cold water, without heating the water inside the robot's tank.
The Qrevo Edge S5A's great advantage is in the extendable mops. These project towards the edges during mopping, allowing cleaning of skirting boards and corners that would normally be out of reach. The Qrevo S Pro doesn't have this capability, so perimeter mopping will be less thorough.
More importantly: the Edge S5A incorporates dirt detection on both the mops and the floor. This means the robot can detect when the mops are dirty and return to the base to wash them earlier than scheduled. It also identifies particularly dirty areas of the floor and re-mops them automatically. The Qrevo S Pro lacks both functions, so mopping will be more basic and less adaptive.
Neither model automatically removes the mops at the base when you only want to vacuum, so you'll have to do it manually if you don't want to drag them dry across the floor.
Navigation System
Both models use a 3D LiDAR turret to map the home and avoid obstacles. Both include SmartPlan 2.0, Roborock's intelligent cleaning system that optimises routes and adjusts parameters according to the type of floor detected.
The Qrevo Edge S5A features the RR Mason 11.0 processor, whilst the S Pro's chip is not identified in the specifications. This may translate into differences in processing speed or navigation precision, although in practice both should offer reliable mapping.
Neither integrates a front AI camera, front 3D laser sensor, pet recognition, curtain detection, or remote camera access. They also don't include LEDs for night vision. Obstacle avoidance is managed through LiDAR, without advanced visual recognition systems.
Runtime and Battery
There are no differences here. Both feature a 5,200 mAh battery with a declared runtime of 180 minutes. This capacity allows covering large homes in a single session, even with active mopping which usually consumes more battery due to returns to the base to wash mops.
In practice, 180 minutes can translate to surfaces of up to 200-250 m² depending on mapping complexity, number of obstacles, and whether mopping is activated. Both robots manage charging autonomously and resume cleaning if the battery runs out before finishing.
Smart Features
Both models overcome obstacles up to 20 mm in height, which allows navigating thick carpets, expansion joints, or small level changes between rooms. Neither incorporates a robotic arm or its own voice assistant, although both are compatible with Alexa and Google Home for external voice control.
Multifunction Cleaning Base
Both bases share most functions: they auto-empty the dustbin into a 2.7-litre bag, wash the mops with hot water, and dry them with hot air. The clean water (4 litres) and dirty water (3.5 litres) tanks are identical, as is the absence of an integrated detergent tank, UV disinfection, and plumbing connection.
The difference is in the washing tray's auto-cleaning. The Qrevo Edge S5A includes 2.0 auto-cleaning, a system that automatically cleans the tray where the mops are washed to prevent dirt accumulation and bad odours. The Qrevo S Pro doesn't have this function, so you'll have to manually clean the tray more frequently to maintain the base's hygiene.
This can be especially noticeable in homes with pets or where mopping is done daily, as the tray accumulates organic residue and can generate odours if not cleaned regularly.
Dimensions
The diameter is practically identical: 352 mm on the Edge S5A versus 353 mm on the S Pro. The relevant difference is in height. The Qrevo Edge S5A measures 98 mm, whilst the S Pro is 1.5 mm lower at 96.5 mm. It may seem like little, but in practice those millimetres can determine whether the robot passes under certain low furniture, sofas, or beds with little clearance from the floor.
The robot's dustbin also varies slightly: 325 ml on the Edge S5A versus 330 ml on the S Pro. A minimal difference that won't affect real-world use. The robot's water tank is 80 ml in both cases.
The bases have almost identical measurements: 340 mm wide and 487 mm deep. The Edge S5A's base height is 521 mm, 2 mm more than the S Pro's 519 mm. Imperceptible differences that don't affect the space they occupy.
Real-World User Experience
For homes with pets, the Qrevo Edge S5A offers clear advantages thanks to the DuoDivide anti-tangle brush. Maintenance will be less frequent and you won't have to be cutting tangled hairs every few days. The S Pro, with its single brush, will require more attention if you have dogs or cats that shed hair.
If edge and corner mopping is a priority, the Edge S5A stands out again with its extendable mops and extendable side brush. The result will be visibly better on skirting boards and corners. The S Pro will leave these areas less clean.
The Edge S5A's dirt detection makes a difference in homes that get very dirty or have young children. The robot adapts on its own, re-mops where needed, and washes the mops when it detects they're dirty. The S Pro follows a fixed pattern without adapting to actual dirt levels.
The 2.0 auto-cleaning of the tray on the Edge S5A reduces base maintenance. If you don't like having to manually clean components, this is a real advantage. The S Pro will require you to clean the tray periodically.
For homes with low furniture, the S Pro has 1.5 mm less height. It may seem irrelevant, but in borderline cases it can be the difference between accessing certain areas or not.
Conclusion: Which to Choose?
Choose the Roborock Qrevo Edge S5A if: You have pets and want to minimise main brush maintenance. If you value thorough edge and corner mopping with extendable mops. If you prefer a robot that detects dirt and adapts its cleaning autonomously. If you want to forget about cleaning the base tray thanks to 2.0 auto-cleaning. It's the most complete and advanced option in this comparison, designed for users seeking maximum autonomy and superior mopping results.
Choose the Roborock Qrevo S Pro if: You're looking for a robot from the Qrevo family with a multifunction base but without needing the Edge S5A's most advanced features. If your home has very low furniture and those 1.5 mm of height difference could be decisive. If you don't have pets that shed a lot of hair and the single brush doesn't pose a maintenance problem. It's a simpler option that maintains the essentials of the Qrevo range with hot water and air washing and drying base, but forgoes the detection and extension technologies that make the Edge S5A stand out.
