Long-Lasting Battery

A 100% battery boost to 5200mAh means enough energy for 2.5hours of non-stop cleaning, or to clean up to 2152sqft.

Large Dustbin

A 640ml dustbin stores more debris, meaning it can be emptied less often and cleans in one go.

App and Voice Control

Start/stop cleanups, set suction strength, set schedules, and more in Mi Home APP, or start and stop cleanup using Amazon Alexa.

Note: 2.4Ghz Wi-Fi required for the app connection.

Auto Top-Up

When cleaning large spaces, E4 will return to the dock, top-up its battery, and continue vacuuming where it left off.

Note: Please see the manual to place the dock in the right area.

Optional Mopping

An add-on mopping system, 28% larger than those found on other E series products, is ideal for removing additional fine dust that other vacuums may miss.

*Mopping system needs to be purchased separately on Amazon.

Cliff Sensors

An array of Cliff Sensors always scan for ledges and steps, preventing accidental falls.
