The details

Do you and your family live in a big home? If you do, not every robot vacuum will be suited to clean your home. The right model ought to have a powerful suction, long  battery life, and a reasonably large dustbin capacity.

With Roborock E4 robot vacuum cleaner, you get all these features and then some. Here’s everything you need to know about this nifty cleaning gadget.


There are several things you’ll love about Roborock E4. One of these is the ability to choose from different cleaning modes. These are set in increasing order of suction power, and they start from Silent to Balanced, Turbo and lastly Max. The default cleaning mode is Balanced.

Another aspect you’re sure to love entails its cleaning performance, especially on bare floors. This bot has no issue capturing pet hair, large-sized debris or much smaller debris like rice.

It’s able to achieve this due to its strong suction power, which is rated at 2,000 Pa. The device also comes equipped with two brushes. The main is an anti-tangle one while the one on the side is made of silicone.

Ease of use

Roborock E4 is fitted with a number of features that make it super easy to use. The 640mL dustbin is a good case in point. This provides way more room to accommodate the dirt being trapped; hence, reducing the frequency for emptying.

Furthermore, you’ll never have to worry about Roborock E4 getting stuck thanks to its flawless navigation system.

It lacks the LIDAR (laser mapping) navigation found in its higher-priced siblings. Instead, it has an OpticEye navigation system that produces a pretty effective S-shaped cleaning route.

By moving in this pattern, it ensures that it doesn’t miss any spots. And even if it misses, it’s able to detect and clean these spots. The fact that it can generate a map of the area it’s just cleaned has to be the icing on the cake.

Its self-tuning of power settings is another feature that contributes to its user-friendliness. It’s able to detect the type of surface it’s about to tackle and adjust the cleaning mode accordingly. For instance, if it encounters a carpeted area, it cranks up the suction to the maximum 2,000 Pa, guaranteeing an efficient cleaning on this surface.

Battery life 

As we mentioned earlier, the Roborock E4 offers one of the longest runtimes that you’ll ever get from robot vacuums.

When operating in its highest setting – Max mode- it delivers a runtime of slightly under two hours. And when in Silent mode, you can expect it to last for a solid 200 minutes, which translates to over three hours.

That said, it’s important to note that this gadget takes a while to recharge. And as soon as its battery falls to less than 20%, it stops cleaning and starts looking for its charging base.

On the brighter side, it’s not hard to figure out that the reason it’s stopped working is because it’s running low on battery. Once this happens, the power button switches from white to red color.


The Roborock E4 is on the higher side of the price spectrum. But it offers a decent cleaning performance that more than makes up for the cost you pay.

It’s particularly good at cleaning bare floors, and thanks to its compact design, it can easily maneuver in tight spots. The best thing about it is its generous battery life that allows the bot to clean for at least 3 hours before requiring a recharge.

Final verdict

Roborock E4 is best suited for an individual who has a large home. This is because it has a powerful suction, ideal for cleaning all kinds of surfaces including carpets. It also has a long runtime of about 200 minutes. This allows it to clean large-sized spaces before it has to be recharged.
