Can Roborock E4 robot vacuum cleaner clean pet hair?
That significant cleaning range makes the E4 a great fit for a family home with plenty of ground to cover, as well as for smaller homes, and it’s also got a jumbo-sized 640ml dustbin to make sure you don’t have to empty it all the time. Plus, the vacuum has a HEPA-Type filter that’s easy to take out and wash, making it reusable – it’ll block dander and pollen to make sure that the E4’s cleaning doesn’t leave any dust or particles in the air in its wake.
If you’ve got pets in your home, that’s also no issue – the vacuum’s nice and quiet, so shouldn’t alarm them, while it’s also got smartly-designed anti-tangle systems for its brushes that mean animal hair won’t gum up its works.

Roborock E4 robot vacuum cleaner review
Size and weight
The Roborock E4 is your average size and weight of a robot vacuum, coming in at just 11.08lbs, with dimensions of 13.78 (W) and 3.57 (H) inches in total. That means it’s both lightweight enough to roam your home safely and quickly, small enough to fit under low hanging furniture, yet broad and spacious enough to pick up and store every last crumb on your floor in its 0.64 liter dustbin.
640-mL Dust Cup – Roborock E4 robot vacuum cleaner
Inside of this robot vacuum, there is a 640ML dustbin. It may not sound like a lot, but when compared with other robot vacuums, it is. As a result of having this large dustbin, you can vacuum for longer periods of time without having to empty the dustbin.
When this is combined with the battery, which provides plenty of battery-life, you can vacuum for a long time without any interruptions. In having access to these features, the entire process of vacuuming and cleaning your floors is much easier and far more convenient.
Intense 2,000-Pa Suction
Let’s take a moment to acknowledge just how powerful the E4 truly is. On its maximum power mode, the E4 can deliver up to 2,000 Pa of suction power that makes this robot capable of picking up and removing hair and dust from medium-pile carpeting in one or two passes. For a budget-friendly robot, we were extremely impressed by how powerful the E4 is and how reliable it is at picking up surface debris.
Dual Gyroscope + OpticEye Navigation
The way the E4 moves around is by using a series of sensors to detect its surroundings. This gives the E4 a good idea of the floor’s layout and where obstructions and obstacles lay. However, it does not have the capacity to save digital maps so it’ll need to repeat this process every time it begins its cycle.
Easier Brush Maintenance
If you’ve owned a robotic vacuum cleaner before, you may have become frustrated by a clogged suction inlet. With the E4, this problem no longer exists! If the brushes are fully detachable to remove human and pet hair with a quick swipe for easier maintenance.
Washable HEPA Filter
The E4 comes with a super-fine HEPA filter that traps more than 99% of particles as small as 0.3 microns. The filter is washable so you won’t need to purchase replacements as frequently as you would in other competing robots. The Mi Home App will alert you when it’s time to give the filter a quick wash, rinse, and dry.
Optional Mopping Module – Roborock E4 robot vacuum cleaner
To make your E4 even more useful than it already is, you have the option of picking up a mopping module which replaces the robot’s dust bin. With a bit of water, the robot will run across your floors using a slightly moistened microfiber pad to remove any lingering dust particles the vacuum may have missed.
The water output rate is customizable in the Mi Home App.
Simultaneous vacuuming and mopping is not supported, and you cannot establish no-mop zones either. Prepare to get your carpets slightly moistened.
No-Go Zones Not Supported
The E4’s sensors are unable to store a digital layout of your home’s floors, and thus, users cannot define no-go zones for specific rooms or areas. Also, virtual boundaries and strips do not work with the E4. The only way you can prevent it from entering a room is by closing the door. A minor inconvenience but completely understandable by its cheaper-than-expected price tag.
Moves Quicker, Cleans More
According to the manufacturer’s reports, the E4 is able to move up to 10% quicker than certain older models which allow it to clean a wider surface area while using the same amount of battery life. The quicker-paced E4 can cover up to 2,152 square feet per charge before needing to recharge.
Smart Controls with the Mi Home App and Alexa
Naturally, the Roborock E4 comes with a handy app, as well as voice activation that helps keep the entire process almost completely hands free.
Using the E4 is as simple as any intelligent robotic vacuum cleaner. This unit is compatible with the Mi Home App which shows users how long the robot has been working, how much longer it has to clean, the remaining battery life, and access to a programmable scheduler. Additionally, you can ask Alexa to relay your commands to the E4 if you don’t feel like whipping your smartphone out.
There’s almost no limit to what you can achieve with the app, which even works when you’re not home – perfect for those sudden changes of plans that see visitors arriving unannounced. Start, stop and pause the Roborock E4, monitor the cleaning mode, set a timer, and even start maintenance on your robot vacuum, all without having to lift a finger.
Alexa compatible
To make use of the myriad of wonderful features this robot vacuum cleaner offers, you’ll be relying on the smart functionality that it offers. Smart functionality that involves using a smart device – your smartphone, for example – to access this robot vacuum and to access the plethora of features and settings that it gives you access to.
What is especially nice about the smart functionality this robot vacuum cleaner offers, is the fact that you can make use of it using more than just your smartphone. If you have a smartphone or an Amazon Alexa device, you can access this robot vacuum and the different features and settings that it offers. And, if you are using an Amazon Alexa device, you can use your voice to control this robot vacuum.
Massive 5,200-mAh Battery
Speaking of the battery, the E4 is equipped with an impressive 5,200-mAh battery that lasts up to 180 minutes per charge. When the battery reaches 20% or less, it’ll immediately dive into its charging dock to refuel. After being topped off, the E4 will pick up exactly where it left off without further commands. The maximum cleaning time per charge depends on which mode is active and for how long.
