It is recommended that during this first configuration both the robot and the mobile phone are close to the router.
As well we can search for it manually, canceling this window and clicking on “add manually” at the top; Then we will choose "appliances" on the left (it can appear twice, the robots are on the bottom one), and we will choose E4.
Once chosen, The app itself will guide us through the installation process, telling us to press both buttons at the same time for 3 seconds, to restart the Wifi connection; You simply have to go step by step and we will connect the robot to the Wifi.

Roborock E4 operation
One of the highlights of this Roborock “E series” is its high suction power. Although it is the brand's mid-range, its suction power is comparable to that of many models in the S series, the high-end one.
With 2.000 Pascals of power, the Roborock E4 has a great absorption capacity, which allows it effectively capture all types of dirt, fine dust, hair and coarse particles, obtaining great results on both hard floors and carpets.
As usual for the brand, it has 4 power levels, to be able to choose the most appropriate one based on your cleaning needs:
Furthermore, the E4 It is capable of overcoming obstacles up to 2 centimeters high, so carpets of a certain thickness are not a problem, and activates maximum power automatically when detects that it is on a carpet, to achieve a more thorough cleaning.
The combination of brushes that includes:
The system smart navigation It is not based on LIDAR, like its high-end sisters, but it allows you to map the home and achieve fluid and efficient Z-shaped movements, thanks to the combination of various technologies.
The Roborock E4 includes 13 sensors, including two gyroscopes and the Optic Eye, an optical detection system based on laser and LED. Gyroscopes are digital compasses that allow you to recognize the robot's trajectories and changes in direction, while the Optic Eye performs a constant analysis of the distance traveled.
Two gyroscopes
Optical Eye
Thus, The Roborock E4 manages to map the home with remarkable precision, creating a map of walls and obstacles, moving fluidly and efficiently, up to 10% faster than the Roborock E2 and E3.
Able to navigate complex areas
When the E4 approaches an obstacle, it detects it and slows down, avoiding touching it or doing so gently, without leaving marks.; Even in more complicated areas, such as between the legs of chairs, it is capable of moving adequately, leaving places where there is not much free space.
As an advantage compared to the brand's models with laser navigation, the profile of the Roborock E4 is lower, as it does not have the laser turret protruding, so can more easily sneak under furniture.
The map generated by the E4 is not interactive, like that of its high-end sisters, so It does not have advanced options such as cleaning by room or creating restricted areas. If you are interested in these types of functions, within the brand you can opt for the Roborock S4 (without scrubbing) or by Roborock S5 Max (with scrubbing), although yes, they have a higher price.
The dirt trapped by the robot reaches its large capacity tank, one of the largest in the category, with 640 milliliters, which allows you to clean a medium or large-sized home even more than once.
There is also his E11 high efficiency filter, which is washable for greater comfort and hygiene, which traps microparticles of dust and mites inside to also achieve cleaner air.
Autonomy is another outstanding aspect of this robot. Thanks to its large 5.200 mAh lithium battery, it reaches an autonomy of up to 150 minutes, which together with its great efficiency allows you to clean large surfaces with a single charge (between 150 and 200 square meters).
As if this wasn't enough, the robot has charging and continuation- If it does not finish, it returns to the base and, once charged, resumes cleaning where it left off.
Its high suction power, large tank size and a brush design that reduces tangles They make the Roborock E4 a great ally if there are animals in your house.

In addition to vacuuming, this robot can also mop, so that with a single device we can achieve a more complete cleaning of the home.
Roborock E4 mopping
The Roborock E4 includes a water tank with a good capacity, 180 milliliters, allowing the water flow to be varied, to adjust it depending on the level of dirt and the type of soil.
The water tank with the mop is easy to assemble and remove, and allows for greater cleaning: the robot can mop and vacuum at the same time, capturing more dirt with each pass.

It has great suction power and picks up dirt very well, and it also detects when it needs to increase the power when it is on a carpet.. The tank is large, enough for several times, and the battery life is excellent. I am very happy with my purchase, I definitely recommend it.

It's great, I'm really impressed. It has great suction power and reaches places where it would be difficult for us to reach to clean.. The app is very easy to use and you can program it, it shows you the cleaning map, etc. Very happy.
