Roborock S4: The best Roborock robot vacuum cleaners in 2021

Roborock S4

If your house doesn’t get too dirty and you don’t need to scrub often. Or, on the contrary, it gets so dirty that you have to scrub by hand, the Roborock S4 robot vacuum cleaner has the same features as its older brothers S5 Max, and even the S6, but without the scrubbing functions , at a cheaper price.

It is a cleaning robot designed to sweep and vacuum, and it does it just like the best, thanks to its 2000 pascal suction power capable of lifting an AA battery from the ground.

With its autonomy of more than 1.5 hours , it is enough to thoroughly clean a house of up to 200 square meters, on a single charge. When the 5,200 mAh battery runs out, it automatically returns to its charging station, so you don’t have to worry about a thing.

Roborock S4

Of course, it costs him to climb the carpets a little more than the S5 Max . Keep this in mind if you have high rugs.

It uses the latest laser sensor technology to map the entire house with 98% accuracy . This ensures that you do not leave any corner to be cleaned. From the mobile app you can put virtual barriers so that it does not clean certain rooms, or even certain areas of a room.

If you are just looking for a robot vacuum that sweeps and vacuums, the S4 has the same features as the S5 but without the scrubbing function, at a more affordable price. It is capable of mapping the house to clean only the areas you request, and it recharges automatically.

Its movement algorithm makes it almost impossible for it to get caught between objects or in a hole. And thanks to its transparent tank you can see when it is full, to empty it.

Roborock S5 Max: The best Roborock robot vacuum cleaners in 2021

Roborock S5 Max

If you are looking for a good cleaning robot specialized in scrubbing , the Roborock S5 Max is an option to consider, because it is designed precisely for that.

Its scrubbing mode is one of the most advanced out there . From the app you can select the amount of water you want to use depending on the type of floor, and you can define areas that you want it to vacuum but not scrub, for example carpets.

With its 290 ml tank, it is capable of scrubbing a 200 square meter house in one go , and a 65 meter floor, up to three times. It is also one of the few robots that does not scrub using the weight of the water tank on the mop, because with this method, when the tank is emptied, the pressure drops. It has its own pressure spring that exerts a force of 300 grams regardless of the amount of water in the tank.

This model has a suction power of 2000 Pa and, thanks to its specialized fan that rotates at 1,500 rpm, it is able to direct the air flow towards the interior and prevent the dust from being dispersed throughout the house.

The Roborock S5 Max  features a 360-degree laser mapping system that draws a floor plan of your home with 98% accuracy. Once done, it recognizes the different rooms so that you can schedule cleaning according to your needs.

Thanks to its numerous sensors (accelerometer, an odometer, infrared sensors and compass), it avoids obstacles, never falls down stairs, and does not get stuck.

Roborock S6

Roborock Robot Vacuum Cleaner

The S5 Max is a great robot vacuum cleaner, but it has been improved in some respects by the S6 range, of course.

Although both models are very similar in power and functions, the S6 makes a little less noise, and has a denser brush that traps dust even more . They have also improved the adaptive algorithms that decide the robot’s path, based on the maps it creates with its laser sensors and quad-core processor. It also has some more sensor, for example an odometer to measure distances. However, the S5 Max has a larger water tank , so it can scrub more surface in one go.

It uses LIDAR laser sensors, the most accurate there is, to map the whole house and not leave any corner. The high-precision laser spins at 300 rpm, mapping the house with 98% accuracy. You can see the area that has been cleaned to check if something is left, or program it through the mobile app, via WiFi, choosing the rooms or areas that you do not want to clean.

It has no less than 14 different sensors , including accelerometer, the aforementioned odometer, infrared distance sensors, compass, anti-fall, and others. It is even capable of climbing obstacles of up to 2 centimeters.

Like the S5 Max, it has a suction power of 2,000 Pascals , with a 5,200 mAh battery and a range of about 2.5 hours . But you don’t have to worry because it recharges itself, so it can clean the whole house when you’re out and about.

It is compatible with the Alexa assistant. If you have an Amazon Echo device,  you can control it with your voice without using your mobile.

Roborock S6 is priced at € 499 on Amazon .

Roborock S6 MaxV

Roborock S6 MaxV

It is the first to have, in addition to the LIDAR laser sensor, a double stereoscopic camera that mimics human vision . This dual camera allows you to calculate the depth, distance and size of objects, so you can navigate them more effectively.

You can also create 3D maps and the desired multilevel maps , separating the floors of a house. It was a highly requested feature by users.

Roborock S6 MaxV

The Roborock S6 MaxV  is the first to use the Qualcomm APQ8953 processor , 50% more powerful than the S6. It releases, in addition to the usual CPU, a GPU or graphics chip that it uses to implement artificial intelligence algorithms .

Thanks to AI and deep learning, it is able not only to see objects, but to distinguish what they are. For example, it is able to distinguish a carpet from a scale that is exactly the same height, so it will not try to get on the scale to clean it, as other robots do that do not differentiate objects.

It can even send unknown objects it finds during the cleaning phase to your mobile . He can let you know, for example, if the dog has done his business inside the house, and mark exactly where they are. Or if the children haven’t picked up their toys before starting to do their homework …

And you don’t have to worry about privacy. Any image captured by the cameras is discarded once processed. Nothing is duplicated, nothing is stored, and nothing is sent to the cloud.

Along with these unique functions, the new Roborock S6 MaxV robot vacuum cleaner offers the best features in the company’s entire catalog. Its suction power is 25% higher, reaching 2,500 pascals. The water tank for scrubbing doubles its capacity, up to 290 ml. And it uses an intelligent scrubbing system that allows you to define the amount of water used in each room.
