Cleaning Performance

This robot vacuum does a decent job on both carpets and hard floors. It has a spinning side brush to sweep dirt from the edge of the cleaning path towards the center of the vacuum where it will be picked up. This ensures that it doesn’t leave uncleaned areas along walls and corners.

The main brush is a bristle brush with a clever V-shaped pattern that is very easy to clean. It also does a great job on pet hair when compared to most other brush designs.

When it comes to suction, the Roborock E4 comes with a powerful motor that can generate up to 2000 Pascals of suction power. This is more than enough for most of the common particles you’ll find in a home.

If you need a robot vacuum that can also function as a mop, have the option of getting a mopping pad for this vacuum. This pad has a simple design with a small tank in the detachable plate and a gravity-fed system where water drips directly to the cloth.

The mopping pad isn’t the greatest in the market and it doesn’t give you much control over the mopping other than controlling the amount of water dripping onto the cloth, but it will get you better results than vacuuming alone.

This robot follows a systematic z-shaped cleaning pattern that helps reduce missed spots while ensuring that the robot finished the cleaning job faster when compared to a random cleaning pattern. It uses two gyroscopes and an optical eye motion tracking system.

Together, these two systems do a great job of ensuring that the vacuum chooses the best possible route and floor coverage for your home. However, this robot doesn’t come with laser navigation available in the more expensive S-series models hence it won’t give you a detailed map of your home that allows you to set virtual boundaries.

Battery Performance

The Roborock E4 comes with a powerful 5200mAh Lithium-ion battery that does a great job of powering the device. Despite the powerful suction, this vacuum comes with an impressive runtime of up to 200 minutes.

This is more than enough time for cleaning most homes, but if it ever runs low on charge before completing a cleaning task, it is clever enough to interrupt the cleaning and find its way to the charging dock for a charge, then it will come back and resume from where it had stopped.

Part of the reason why this vacuum has managed such a high runtime is that it has the carpet boost feature where the suction is increased automatically when the vacuum detects that it has reached a carpeted area. This means that it won’t have to keep operating at full power when the extra suction isn’t necessary.

Filtration and Control

This robot comes with a 640 ml dust collection bin that is significantly larger than most vacuums within its price range hence you won’t have to empty every few minutes. The filter is placed on one side of this dust bin and it is washable to reduce maintenance costs.

When it comes to controlling this vacuum, you get plenty of amazing options that help you get the best out of your robot. For starters, you can link to an Alexa device to get voice control and give commands without lifting a finger.

If you want more, you can download the Mi Home smartphone app that allows you to set cleaning schedules, view cleaning history, access important maintenance information, control the amount of suction, and switch between cleaning modes.

You can also use this app to start, stop, and pause cleaning remotely.


For a budget vacuum, the Roborock E4 offers a great return on investment. It does a decent job picking up different types of debris from most surfaces and it comes equipped with many amazing features that make it easy to use and more practical around the house.

Unless you need the more sophisticated features that come with laser navigation, this vacuum is a great investment that will help you have clean floors, great features that make it easy to use, and an affordable price tag.
