Xiaomi continues to develop the Roborock series - a line of robotic vacuum cleaners for the home. Its new representative was the Roborock S4 model with a new design - a translucent lid. The device has become more maneuverable, better passes tight places in the house. The model has several suction modes, an excellent filtration system, a large-capacity battery and a new application for a smartphone. I will tell you in detail about the features and characteristics of this gadget in my review.
Appearance
Xiaomi did their best: with a translucent cover, it looks very interesting. The glossy plastic case is made in black. The case is very easily soiled, there are always traces of touch on it. On the top panel there is one large button, divided into two parts. The first is responsible for turning on / off the robot vacuum cleaner, and the second is for sending it to the docking station. A quick inspection immediately catches the eye in the place where the high-precision LDS sensor (lidar) is located, which reads the location and shape of objects, and then builds the most convenient cleaning route. Along the perimeter of the device are 12 different types of sensors that prevent collisions and falls from a height. The main brush of the robot vacuum cleaner received compacted bristles and a collapsible design with removable tips - this way the manufacturer simplified cleaning the brush of hair and wool. There is one lateral rubber brush.
Equipment
The vacuum cleaner is packed very carefully, in 2 boxes. The first is protective cardboard, and the second is proprietary, on which its characteristics and functions are given. Inside the box, except for the vacuum cleaner itself:
- Dock station.
- Spare filter.
- Robot cleaning brush.
- Charging cable.
- Instruction manual in 5 languages.
The scope of delivery is small. For many models from Xiaomi and other manufacturers, it is more diverse.
Functionality
The Roborock S4 robot vacuum cleaner is most suitable for use in rooms without carpets. The device does an excellent job of cleaning smooth floors or carpets with a small pile. The suction power is 2000 Pa. The following operating modes are available to control the suction power:
- quiet (50 dB, 1200 Pa);

- max (65 dB, 2000 Pa).
You can control and select modes through the Roborock proprietary application for Android and iOS. It came to replace Mi Home, which has shown itself not from the best side. The new application has become more convenient, updates are regularly released for it: new functions appear, errors are fixed. You can track work online, make map settings, divide the room into separate zones. This model provides storage for up to three cards. The transparent trash bin has a volume of 420 ml. Dust collector - with HEPA filter class E11. It even catches mold, dandruff, allergens. The filter is easy to clean and washable under water from the tap; a second spare is included in the delivery set. The T4 comes with a large 5200 mAh battery.This charge is enough for a vacuum cleaner for 150-180 minutes of work without interruption, a full battery charge will take 300 minutes. The device can clean a large area - 250m2... The vacuum cleaner is able to overcome obstacles with a height of 15 mm. Has protection against falls, collisions.

Verdict
The Xiaomi Roborock S4 (T4) robot vacuum cleaner is very interesting, I especially liked the design. Price -: I think it is overpriced. This package is obviously too small: for example, in the model iLife V50 Pro behind it is much more. Xiaomi always cares about ease of use, so the development of a new mobile application is a big plus, although it is still "raw", you need to fix minor flaws, but it works quite successfully.
Pleased with the reliability of the navigation system - this is a rarity among the available models on the market. It is possible to save up to three maps, which can be controlled via the Roborock app. I will emphasize even higher autonomy, a large cleaning area, a new central brush and a HEPA filter. For myself, in this robot vacuum cleaner, I found more pluses than minuses.
