Product naming conventions
Roborock's product naming is fairly straightforward for instance if a product name has a plus sign the word plus or the word Ultra it includes an advanced dock in the package.
Navigation
The chosen robots use Lidar to navigate and additional technologies for object recognition. The premium robots are more accurate at recognizing objects comparing to the cheaper lineup.
Performance
Their official suction ranges from as little as 5,500 pascals up to 18,500. The Roborock robots use single and duo system rollers depending on the model. A Roborock is known for its great carpet cleaning. The newest models also represent a smooth mopping experience.
All of the robots have slightly different dust bins and water tank sizes. This is one of those things that might change if you decide not to get the one that comes with an auto-empty dock.
Mopping
The robots use a mopping plate, a vibrating mopping plate, and a dual-mop system.
The Roborock Q8 Max+ has an electric water tank, no auto-refill function, or vibrating mopping mad. An old famous Roborock's mopping system.
The Roborock S7 Max and S8 MaxV use Sonic mopping system. It's a plate that vibrates and lifts on carpet.
The Roborock Qrevo series has a two-mopping pad system that the robot lifts on carpet. Additionally, it extends the mop along edges and corners.
Self-emptying dock
Advanced auto-empty docks that manage one or more of the robot's regular maintenance.
The basic self-emptying base (Roborock Q8 Max+) has a disposable bag and is the smallest.
The Ultra docking station additionally washes and dries the mopping plate, refills the water tank, and cleans its plate.
The Qrevo station contains bigger water containers, has all the same features, and a different design.
App and smart features
Roborock has been a leader with smart features and has a well-thought easy-to-use app.
All of the robots here have the following advanced features:
- no-go zones
- advanced scheduling
- carpet boost
- room cleaning
- zone cleaning
- Amazon Alexa capability
- Google assistant capability
- Siri compatibility with Apple shortcuts
- 3D mapping
The Qrevo and S8 Pro Ultra also have smart suggestions for no-go lines.
Let's break it into three categories: affordable, mid-class, and premium models:
Affordable: Q5 Max+
Mid-class: Roborock Q8 Max+, Qrevo S
Premium models: Roborock S8 MaxV Ultra, Qrevo Slim, Qrevo Edge.
2025 Best Affordable Roborock
The best affordable Roborock is a Q series. The Roborock Q5 has a few modifications, the most affordable with a self-emptying base is the Q5 Pro+.
Roborock Q5 Pro+
The robot has strong suction but does not have mopping. It is a reliable robot vacuum, good for big homes with carpet if you don't need mopping.
Great pick for a big house if you don't need extra features
Mid-class Roborock
That would be the Q8 Max+ and Qrevo S.
The Qrevo is the new lineup with the Qrevo S being the cheapest. It has a bigger base with two water containers and a disposable dustbin. The robot gives you a better mopping experience with two rotating mopping pads. The robot lifts them when step on carpet. The Qrevo S has a higher price tag compared to the Q8 Max+.
Roborock Q8 Max+
The Q series is an affordable model line for those who want Roborock's famous vacuuming performance and don't need a fancy mopping system.
Roborock Q8 Max+
The best navigation in the series
The Roborock Q8 Max+ is the best in the Q series with a basic station and mopping system. It is a powerful robot vacuum ideal for homes with carpets, for those who don't need extra mopping features.
To sum up
The Roborock Q8 Max+ is a robot vacuum to do a vacuuming job and daily mopping routine.
The Roborock Qrevo S is an advanced robot with a rich-featured station that self-empties, washes&dries the pads, and refills the water tank. It has a different mopping system that makes mopping a much better experience with almost no maintenance from your side. Withh all those features, the robot costs more.
2025 Premium Roborock
The premium Roborock S8 series and the latest Qrevo are a big step up compared to the previous models.
The following models also have a modification with refill and drainage system.
Roborock S8 MaxV Ultra
The Roborock S8 MaxV Ultra is a premium model with a modern-looking station and detergent dispenser. It raises the brush and extends a side brush along the walls. With a dual brushroller system and a vibrating mopping pad, the Roborock S8 MaxV Ultra is the best premium machine in the whole lineup.
The Roborock S8 MaxV Ultra is the robot for all surfaces
Roborock Qrevo Slim
The Qrevo Slim has a short body, and a new flat Lidar technology thanks to which it goes under most furniture. It is the cheapest of the latest Qrevo arrivals since it's not as powerful and lacks some additional features. Both cleaners extend the mopping pad along the walls and corners.
Roborock Qrevo is pet-friendly
With the app, you can video call and chat with your pets, and take snaps; the robot identifies the pet to avoid when operating.
Roborock Qrevo Slim
Lidar's innovative technology for a shorter body
Has StarSight which is the newest mapping technology thanks to which the robot goes under most furniture. Knows the biggest amount of small objects to avoid. It uses the same Dual rollers and lacks the AdaptLift Chassis so it can't go under anything higher than 20 mm.
Roborock Qrevo Curv
The Curv has a new station that allows setting water temperature, mopping pad drying duration, and wash settings. So far, it is the most advanced station in the lineup.
The Roborock Curv is the most powerful in the lineup
I think the Curv is the most rich-featured robot vacuum in the whole model line. It is a robot for the best mopping experience to add to the great vacuuming performance, when the Roborock S8 Max Ultra is better as a vacuum since it lacks some mopping features the Qrevo Curv has.
Summary
I think that you'll probably be more than happy with whatever Roborock model you choose. They've proven their ability to create highly capable reliable robot vacuums and their fan favorites usually with really good reviews and it's no surprise that they've become one of the best-selling robot vacuum brands in the world.
