Analysis

The famous brand of intelligent robots Roborock, famous for one of Xiaomi’s brands, has become a benchmark for vacuuming robots. It is the best rival of the famous iRobot Roomba, especially thanks to its quality. In the next article we will analyze the Roborock S4. Although by the name you may think it is an old model, it is more recent than other models and will surprise you with its features.

Roborock S4 features: power, navigation and autonomy

The name of this vacuuming robot seems to correspond more to a decision to follow an order according to the price of its models than to its performance. We could place it, for its price, between the Roborock Xiaowa E35 and the Roborock S5, but its characteristics make it a great choice if we want an intelligent robot without spending a lot of money.

It follows the simple design that characterizes the mark, of simple lines and available only in black brilliant color. The dimensions are the same as in all Roborocks: 35 centimeters in diameter and 9 centimeters in height. In the upper part you will find the access to the tank, 2 physical buttons to operate the basic functions and the laser navigation sensor.

And precisely the LDS laser sensor is one of the biggest novelties that this Roborock S4 brings us, since for a very economic price we can get a vacuum cleaner robot with an efficient navigation system. Thanks to this sensor, the robot can create a detailed virtual map of your home to ensure that all areas are clean.

This robot completes its intelligent navigation with 11 sensors: anti-fall, object sensor, walls… It has 4 anti-fall sensors (2 in the front and 2 in the back). Its transmission system has been improved, it moves forward in a more controlled way and it moves backwards with more strength. That’s why the Roborock S4 doesn’t get stuck where others do.

Its suction power is up to 2,000 Pa so it sucks up all kinds of particles and debris. It has 4 levels of operation to adjust the power: silent, standard, strong and maximum. All solid waste ends up in its 420 ml tank where you will also find a washable EPA E11 filter that returns particle-free air to your home.

However, unlike the rest of the brand’s robots, it does not have a carpet sensor so it does not increase the power. However, thanks to its large wheels and its third front wheel, it can overcome unevennesses of up to 2 centimeters. The main brush combines bristle strips and other silicone strips to avoid tangles with hairs. Therefore it is a pet-friendly robot.

This central brush is floating and adapts to the different heights of your floor without stopping cleaning. But there’s another novelty: the front side brush is now made of rubber and has changed from 3 legs to 5 legs for better cleaning. It also adapts its speed, accelerating when it passes over edges or corners and slowing down when working in the centre of the room, to avoid dispersing the debris.

As you see, we have not talked about its scrubbing function, because to adjust its price the Roborock S4 eliminates this function. It is the only Roborock robot, along with the Xiaowa C10 Youth Edition, that does not have a mop. And although it is compatible with Alexa and Google Home, at the moment it can only be linked with Google for accounts in Spain.

In terms of autonomy, the Roborock S4 has a 5,200 mAh battery but thanks to the elimination of certain functions, it can vacuum up to 180 minutes, a time in which it can vacuum a floor of up to 250 square meters. The robot returns to the charging base when the battery is low and resumes cleaning when it is 80% charged until it has completed its route.

Control and program the Roborock S4 through its mobile application

All Roborock models feature support for the Xiaomi Mi Home mobile application, this particular model also supports the Roborock application. However, thanks to the LDS laser sensor we can control and program many more functions than in other models such as Xiaowa. These 5 functions will be really useful for us when cleaning our home:

Programmed cleaning: you can tell your robot when and what areas it should clean.

Cleaning by zones: If you have dropped something, indicate to the robot which is the zone and it will come to clean it.

Virtual walls: Create virtual barriers to prevent it from accessing certain rooms.

Virtual areas with restricted access: Mark the areas you do not want it to clean.

In addition, this robot is ideal if you have a house with several floors, as it can store up to 3 different maps, this allows you to save time when cleaning your home. Another interesting novelty is that we will be able to see a calendar of the maintenance of the accessories so that to have our robot ready is easier than ever.

How to buy the Roborock S4 cheaper and with warranty from Spain

If you have decided to buy the Roborock S4, first you should know that this brand only sells online through its authorized stores. There are sites that buy part of their stock and sell it through online stores, but to get the best guarantee it is best to buy it through reliable online stores.

Questions

Is the Roborock S4 suitable for pets?

All Roborock vacuuming robots are equipped with anti-tangle technology. Both its vacuum system and its V-shaped brush are prepared not to get stuck with pet hair and leave your home spotless. In addition, thanks to its power of 2,000 Pa you can effectively clean all types of floors.

Does the Roborock S4 clean carpets well?

This vacuuming robot has a high suction power of up to 2,000 Pa. However, as mentioned above it does not have a carpet sensor. It can easily pass over carpets thanks to its large wheels that overcome obstacles of up to 2 centimeters, but it will not increase its power when passing over them. Still, it cleans effectively because it is very powerful.

Can the Roborock S4 scrub?

To reduce its cost, the Roborock S4 has eliminated the mop function, so it can only vacuum as it does not include a mop or a tank. However, it vacuums very well and intelligently thanks to its sensors. If the mopping function is important we recommend you look at our blog for other models of the brand as the Xiaowa E3 or Roborock S5 and S6.

What maintenance should I do with this robot?

For these vacuuming robots to clean as the first day is important to perform a small maintenance: empty the tank, remove any stuck hairs, clean the filter ... Fortunately, the mobile application of this robot will inform you of the status of its accessories to make maintenance easier.

Opinions

For a much lower price than the rest of Roborock's models, you can get an efficient automatic vacuum cleaner in this S4 model, which offers an excellent sweeping function on smooth floors, as well as an intelligent navigation that allows you to avoid obstacles, and to cover almost all the surface without problems.

Although it does not have a wet mopping function or selective cleaning, this model meets the expectations in its price-performance ratio as well as in the activities for which it is designed.
