Description Roborock E4
- Methodical Cleaning: Logical Route Planning, intelligent navigation, and a Z-shape route clean your floors effectively and quickly. Infrared-sensors help avoid collisions, and cliff-sensors for preventing accidental falls. An anti-tangle main brush and side brush keep E4 cleaning without interruption.
- 2-In-1 Vacuum and Mop: Get brighter floors with simultaneous vacuuming and mopping. Get up to 2000Pa of power suction with minimum noise and a super-slim 3.55in design. Low enough to reach under beds, sofas, and areas where dirt hides.
- App & Voice Control: Schedule cleanups at anytime and anywhere with the Mi home app. Start and stop cleaning with Amazon Alexa. (Note: No separate remote control provided).
- High-Capacity Battery and Auto Top-Up: A 100% larger 5200mAh battery means enough energy to clean up to 2152sqft. Auto-Top-up means E4 will return to the dock when low on power, recharge, and then pick up where it left off.

Cleaning typeDry
-
Suction powerThe force with which the device sucks up dust and debris is measured in Pascals (Pa). The higher the figure, the more effectively the vacuum cleaner collects even heavy particles. For reference: 1000–1500 Pa is the basic level for smooth surfaces. 2000–2500 Pa is optimal for carpets and pet hair. 3000+ Pa is suitable for deep cleaning and heavy dirt, provides high-quality cleaning.2000 Pa

Cleaning area200 m²
-
Dust container volume640 ml
-
Volume67 dB
-
Self-cleaning baseCharging base that automatically cleans the dust container, removing debris into a special bag or container. This reduces the need for frequent manual cleaning of the dust collector. Of the advantages of the base – You will save time on cleaning the robot container. Cons: Noise when cleaning, The need to buy garbage bagsNo
-
Turbo brushA rotating brush roller that effectively lifts dust, hair and fur from surfaces, especially carpets. This significantly improves the cleaning quality compared to conventional suction nozzles.Yes
-
Number of side brushes1 PC
-
Overcoming the thresholdsA characteristic that determines the maximum height of thresholds that the device can overcome while moving. It is measured in millimeters (mm) and is important for continuous cleaning between rooms without getting stuck.up to 2 cm
Navigation
-
CartographyA technology that allows the device to scan the space and build a map of the room using sensors, cameras or laser sensors (LiDAR). This helps the vacuum cleaner effectively plan the cleaning route, avoid obstacles and work faster and more accurately. Some models are equipped with AI mapping, which uses artificial intelligence algorithms to recognize objects on the floor (cables, toys, shoes, etc.) and optimally avoid obstacles. Smart devices support saving multiple maps for different floors and setting up cleaning zones.Camera

Sensors
-
Carpet detectionA feature that helps the device automatically recognize carpets and change the operating mode. For example, the vacuum cleaner can increase suction power to better clean carpet fibers. Or raise the cleaning base on carpetsYes
-
Dirt detectionTechnology that allows the device to detect the level of dirt on a surface. This allows the vacuum cleaner to increase suction power or go over problem areas multiple times for a better cleaning.No
-
Dust collector filling indicatorA sensor that shows the level of filling of the garbage or dust container. When the dust container is full, the device notifies the user that it is necessary to empty it. This helps maintain efficiency and avoid overloading the motor. (Rare, probably the technology is patented by some manufacturer)No
Battery
-
Battery typeThe technology used to make the battery. The most common types: - Li-Ion (lithium-ion) – lightweight, durable, no memory effect. - Li-Poly (lithium-polymer) – even lighter, can be shaped flexibly, more resistant to overheating. - Ni-MH (nickel-metal hydride) – avoid devices with such batteries.Li-Ion
-
CapacityBattery capacity, expressed in milliampere-hours (mAh). The higher the value, the longer the device can run without recharging. For example, 5000 mAh is approximately 2 hours of operation, depending on the operating mode.5200 mAh
-
Fast chargingAllows user to charge the battery at an accelerated rate, but due to the accelerated charge, the battery will wear out a little faster. This function can be useful if you need to clean a large area within one dayNo
-
Battery life (up to)The maximum duration of operation of the device on a single battery charge. Measured in minutes and depends on the mode of use and the power of the device.200 Minutes
-
Charging timeThe time it takes to fully charge the device's battery. The shorter this time, the faster the device will be ready for use.4.00 Hours
