Introduction
Roborock presents for 2025 three models from its Q series that share many technical features, but with important differences worth analysing before making a decision. The Roborock Qrevo S5V, the Roborock QV 35A and the Roborock QV 35S are presented as options within the brand's mid-to-high range, all equipped with a multifunctional base that washes and dries the mops with hot air.
All three models are designed for homes seeking minimal maintenance thanks to their complete bases, although the power level and some mopping features vary between them. This robot vacuum comparison will help identify which model best suits the needs of each household.
Power and Suction
Suction power marks the main difference between these three Roborock robot vacuums. The Qrevo S5V leads with 12,000 Pa, a figure that places it in the high-end market segment and which is especially useful on carpets or for homes with pets that shed a lot of hair. The QV 35S stays at 10,000 Pa, more than sufficient power for most domestic situations. The QV 35A, with 8,000 Pa, offers the most basic level of the three, although it remains competent for hard floors and daily cleaning.
Regarding the brushing system, the Qrevo S5V incorporates Roborock's DuoDivide anti-tangle brush, a design that pushes hairs towards the central suction gap significantly reducing tangles. This detail can make a difference in homes with long hair or pets. The QV 35A and QV 35S models mount a simple brush, less effective against tangles but functional in homes without these issues.
All three units share an anti-tangle side brush, although none offers side extension or brush lifting during mopping. They also don't lift the main brush when mopping, something that higher-range models do incorporate.
Mopping
All models mop with two rotating mops and lift the mops up to 10 mm when they detect carpets or when returning to the base. This lifting prevents wetting unwanted surfaces and allows transit over thin carpets without problems.
The most significant difference in this section is marked by the Roborock Qrevo S5V, which features mop extension to better reach edges and corners. In practice, this notably improves mopping results on room perimeters, where more dirt tends to accumulate. The QV 35A and QV 35S models don't include this function, being limited to conventional mopping without reaching corners with the same effectiveness.
All three robots mop with cold water, without the option of heating water in the internal tank. None automatically removes the mops at the base when you only want to vacuum, nor do they detect dirt on the mops or floor to reinforce cleaning in problematic areas.
Navigation System
Navigation is identical across all three models. All mount a LiDAR turret to map the home with precision and feature obstacle avoidance. However, none integrates a camera with artificial intelligence, front 3D laser sensor, nor specific recognition of pets or curtains. They also don't offer remote camera access or LED for night vision.
All three feature Roborock's SmartPlan function, which optimises cleaning routes, although they don't have AI stain recognition. For a 2025 Roborock robot vacuum, the navigation system is competent but without the most advanced features that the brand's top-of-the-range models do incorporate.
Autonomy and Battery
There are no differences here: all three models mount a 5,200 mAh battery that provides 180 minutes of autonomy. This capacity allows cleaning medium-to-large homes without the need for intermediate recharges. Real autonomy will depend on the selected power mode and floor type, but under normal conditions it's sufficient for most households.
Smart Functions
All three robots can overcome obstacles up to 20 mm in height, which facilitates passage between rooms with small level differences or transit over thick carpets. None incorporates a robotic arm or own voice assistant, although all are compatible with Alexa and Google Home for control via external voice commands.
Multifunctional Cleaning Base
All models include a multifunctional base with complete self-cleaning. The bases perform auto-emptying of the robot's dust bin, wash the mops with cold water and dry them with hot air. Hot air drying helps reduce bad odours and bacterial proliferation, improving system hygiene.
Tank capacities are identical: 2.7-litre dust bag, 4-litre clean water tank and 3.5-litre dirty water tank. These dimensions allow several days of cleaning without the need for manual maintenance.
None of the bases includes self-cleaning of the washing tray, UV disinfection, detergent tank, nor connection to water pipes. They also don't offer an optional kit for pipe connection.
Dimensions
Measurements are exactly the same across all three robots. At 353 mm in diameter and 96.5 mm in height, they can slip under most standard furniture. The bases also share dimensions: 340 mm wide, 521 mm high and 487 mm deep. It's advisable to measure available space before installation, as multifunctional bases require a certain amount of space.
Real-World User Experience
For homes with pets or people with long hair, the Roborock Qrevo S5V is the most practical option thanks to its DuoDivide anti-tangle brush and greater suction power. Brush maintenance will be less frequent and hair collection more effective.
In households where edge mopping is a priority, again the Qrevo S5V makes the difference with its mop extension system. For large homes or those with thick carpets, this model's 12,000 Pa offers superior performance.
The QV 35S positions itself as an intermediate option, with sufficient power for most situations but without the extra features of the superior model. The QV 35A, with 8,000 Pa and no mop extension, fits better in small flats without pets and with predominantly hard floors.
All three models share the advantage of a complete multifunctional base with hot air drying, which guarantees minimal maintenance and good mopping results by washing the mops during the cleaning process.
Conclusion: Which One to Choose?
Choose the Roborock Qrevo S5V if you're looking for the best 2025 robot vacuum within this range, especially if you have pets, carpets or need more complete edge mopping. Its anti-tangle brush and 12,000 Pa justify the investment in demanding households.
Choose the Roborock QV 35S if you want a balance between features and price. With 10,000 Pa it perfectly covers the needs of medium-sized homes without pets, although you forgo mop extension and the DuoDivide brush.
Choose the Roborock QV 35A if your home is small, hard floors predominate and you don't have pets. It's the most economical option of the three, maintaining the complete multifunctional base but with less power and basic cleaning features.
