Who should buy Roborock E4

  • If you are looking for a low-cost robot vacuum equipped with outstanding features, the Roborock E4 might be the one for you. The Roborock E4 is ideal for those who are on a tight budget.
  • If you have pets in your home, the Roborock E4 might be suitable for you because it has a strong suction power of up to 2000Pa that can deep clean your floors and carpets.
  • If you live in a large house, you might be satisfied with the Roborock E4 because it can clean your entire floor by following a zigzag pattern without leaving a spot uncleaned.
  • If you have a mix of carpets and hard floors in your home, the Roborock E4 might suit you well because it has a BoostIQ feature that enables the robot to automatically increase suction when it detects carpets so that it can provide a deeper cleaning and optimize the battery life.
  • If you have a lot of furniture or obstacles in your home, you won’t have to worry about the Roborock E4 because it can efficiently maneuver and clean around obstacles.

Who should NOT buy Roborock E4

  • If you are looking for robot vacuums that can produce a precise map in the app and allow you to set virtual no-go zones or cleaning zones, the Roborock E4 might disappoint you. Instead, you might want to look for robot vacuums equipped with a LiDAR navigation system that produces a precise and customizable map, such as the Roborock’s S6 series (Roborock S6, Roborock S6 Pure, Roborock S6 MaxV).

This is our verdict of the Roborock E4 based on several hours of research of reviews from both experts and users.
Updated 15-06-2021

The Xiaomi Roborock E4 is an affordable robot vacuum with an excellent cleaning performance. It has a more affordable price than the high-end products of Roborock because it is not equipped with a precise navigation system, such as the LiDAR navigation.

It has an optional mopping feature that is sold separately, which also reduces the robot vacuum's price. The advantage of an optional mopping feature is that later on, if you changed your mind and you wanted to have a mopping feature, you can still buy the mopping pad.

The Roborock E4 is equipped with a dual gyroscope navigation system that allows the robot to follow a preprogrammed zigzag pattern to ensure that the entire floor is vacuumed without leaving a spot uncleaned. It also produces a map within the app to show you the areas it has cleaned. If the Roborock E4 drains its battery while in the middle of its cleaning cycle, it can recharge and go back to the place it left from so that it won’t have to go over the cleaning cycle. It can also find its docking base without a problem. The Roborock E4 can also easily maneuver around obstacles and furniture with the help of the gyroscope and OpticEye sensors.

However, it doesn’t display a real-time mapping and only shows the created map after the cleaning cycle. You also cannot set virtual barriers and select the rooms you want it to clean from within the app. So, the map it creates doesn’t do much and is just for viewing purposes.

The Roborock E4 has silicone side brushes. Unlike robot vacuums that have side brushes with bristles, the Roborock E4’s side brushes won’t get tangled with hair. This means that the side brushes are easier to maintain and clean. It also has a large dust bin of up to 640ml that can store a lot of dirt from fine to large debris.

The app also has several features, but because it is a budget robot vacuum, it does not have various features, such as those in the Roborock S-series. But still, the companion app of the Roborock E4 functions well, provides you with a set of options, and can help you monitor the robot.

Overall, the Roborock E4 is worth its price. It may lack a few advanced features, such as virtual barriers within the app but it is understandable since it has an affordable price.
