Roborock E4 vs. E35 vs. Coredy R750
If you need a robot that will automate cleaning for you, you might want to consider choosing between the Coredy R750, Roborock E4, and Roborock E35.
Many things worry us during these unprecedented times. Cleaning and mopping floors should be the least of our concerns. However, the idea of having a little robot to vacuum and mop your floors may sound like a luxury to the average homeowner.
While the likes of Roomba s9+ and i7+ may seem to cost you an arm and a leg, you can actually enjoy the perks of an automated cleaner at half the price of these popular units.
The Coredy R750, Roborock E4, and Roborock E35 work primarily as a vacuum cleaner, but you may also employ them to mop your floors. All three units work well for both bare floors and textured surfaces.
But between Coredy R750, Roborock E4, vs. E35, which among these robot mop-and-vacuum hybrids should you pick? Read on to learn more about their distinctive features.

Roborock E4
The Roborock E4 shares many common features with the E35. Among these are the 2000 Pa suction power, 5200-mAh-capacity battery, 640-ml dustbin capacity, and smartphone integration.
But unlike its predecessors, this newcomer is packed with more advanced sensors and software to surmount the previous models.
For starters, the E4 features a tiny LIDAR scanner on top of the unit. Using the OpticEye™ motion tracking, the robot tracks its movements through the corners and obstacles along the way.
You may also monitor the robot’s progress in real-time via the app. The upgraded sensors and software boost the E4’s cleaning efficiency up to 11% more, notes the manufacturer.
My favorite part, however, is the robot’s ability to climb rugs and doorway thresholds that are up to 0.8-inch in height.
The E4 is also capable of mopping your floors, but the mopping system is optional. So, it boils down to you whether or not you want to get the mop attachment.
- 2000 Pa maximum suction power and auto Carpet Boost
- Uses inertial navigation (OpticEye™ motion tracking + dual-gyroscope)
- 0.8-inch climbing ability
- Has six cleaning modes to choose from
- Offers an optional mopping system that is 28% larger than previous developments
- Houses a 5200 mAh battery that lasts up to 150 minutes per charge
- Has a 640 ml dustbin capacity and washable HEPA filter
- Optional mopping system
- Can be very noisy
- The setup can be difficult due to the lack of instructions
- Its mopping ability is not equal to the robot’s vacuuming standard
Roborock E35
The Roborock E35 is a mid-tier robot vacuum that bridges the gap between budget-friendly options and flagship models.
For the price of a Roomba, you can get two or even three of these competent cleaners and enjoy the perks of a mopping system. The E35 knows how to avoid rugs and carpets while in mopping mode, so it is such a relief that you don’t have to babysit your robot vacuum.
The most impressive quality of the Roborock E35 is its 2000 Pa motor, which is a rare feature in mid-tier robovacs. This unit does a superb job of extracting pet hair and other deep-seated debris from carpet fibers.
The E35 can tackle medium- and high-pile carpeting since the robot uses its maximum suction power when Carpet Boost is on. Fortunately, this model has a crazy long battery life of 150 minutes and a sizable dustbin that can hold up to 640-ml worth of debris.
Although the Roborock E35 doesn’t boast of cutting-edge navigation, it vacuums in straight lines and doesn’t miss a spot. Equipped with dual-gyroscopes and dual-optical motion tracking sensors, it speeds through floors in a seamless manner and wiggles itself in narrow spaces to clean hard-to-reach areas.
Likewise, it dances around stray objects to prevent jamming and slows down when it approaches furniture.
- Comes equipped dual-gyroscopes and dual-optical motion tracking sensors for creating quick and effective cleaning paths
- Has a network of 13 sensors to provide efficient cleaning in complicated areas
- Offers six cleaning modes to give you the flexibility to get the right clean
- Offers Spot Cleaning and Carpet Boost
- Boasts of 2000 Pa powerful suction
- Houses a 5200 mAh battery that lasts up to 150 minutes per charge
- Has a 640 ml dustbin capacity and washable HEPA filter
- Has the ability to vacuum, mop, and sweep
- The motor can be very loud during its maximum setting
- The robot may sometimes experience connection issues
- Difficult to configure over WiFi due to the lack of instructions
Coredy R750
The Coredy R750 is an affordable option that offers plenty of pop. Not only can the slim robot navigate underneath furniture with ease, but it glides over rugs and transitions from hardwood floors to low-pile carpets seamlessly, as well.
The robot automatically boosts its suction power from 600 Pa to 1000 Pa when it is cleaning carpets. But even on its highest setting, the Coredy R750 is no louder than a box fan.
So, hats off the quietest robot vacuum in this list!
What’s more, this unit also features a mopping system. However, this unit lacks some of the most coveted mapping technologies. And so, the robot may get lost in a big house with multiple archways or open doors. Luckily, it comes with two 6.6-feet boundary strips, so you can put up virtual boundaries right away.
Another added benefit of this unit is that you can link it with your smart devices.
I also like that Coredy goes out of its way to help its user understand what the robot is doing and what it is saying. You will find plenty of informational stickers on the packaging, as well as underneath the unit.
- Boasts of Boost-Intellect Technology, enabling an automatic increase in suction power
- Max suction power is 1600 Pa, which is a lot higher than other models in its price range
- Uses a washable HEPA filter that you can easily remove for cleaning
- Comes equipped with a 2600 mAh battery, offering 120 minutes of battery life per charge
- Includes a pair of extra spinning side brushes and two 6.6-feet boundary strips
- Compatible with Amazon Alexa and Google Assistant
- Vacuums and mops simultaneously
- The cleaning pattern is random
- No mapping abilities
- You can’t tell where the robot is currently cleaning
- Not that effective for high-pile carpets
Face to Face Comparison: Coredy R750 vs. Roborock E4 vs. E35
Navigation and Mapping
Roborock E4
The Roborock E4 is a quick and systematic cleaner, thanks to its network of sensors. This model comes equipped with onboard gyroscopes that will identify small changes in the angle of motion, including whether or not the robot has flipped. The robot can track its movements, as well as identify edges and obstacles.
Best of all, the E4 features OpticEye™ motion tracking. Equipped with a laser and a LED-based motion tracking system, the robot will know where it has been and create accurate calculations of the zones it needs to cover.
With all these features combined, the Roborock E4 can create an internal map and the best cleaning path so that it finishes its task a lot faster the next time.
Brushes
Dirt Detection and Cleaning Modes
Roborock E4
Unfortunately, the Roborock E4 doesn’t seem to offer a feature equivalent to Dirt Detect™.
As for the cleaning modes, you may choose between Silent, Balanced, Turbo, Max, Gentle, and Carpet.
Dustbin Capacity and Filtration System
Roborock E4
The Roborock uses a HEPA E117 cartridge filter to ensure highly effective filtration of the air in the lowest possible resistance.
What’s more, the filter is washable so that you can save some more on maintenance costs.
Connectivity
Roborock E4
To make most of the Roborock E4, you need to download the Mi Home app. Among the many things you can do, include the following:
- Set detailed schedules
- Start or stop cleanups
- Adjust the suction strength on the fly
- Receive notifications
- View detailed cleaning history
- View your home’s layout
While the Mi Home app gives you numerous ways to manage your robot, you may also integrate voice control through Google Assistant and Alexa for hands-free operation.
Power Suction
Roborock E4
The Roborock E4 has a suction power rated at 2000 Pa on its highest setting, which is an 11% increase compared to previous models, like the Roborock E25.
Run-Time
Roborock E4
Under the hood of the Roborock E4 sits a 5200 mAh Li-ion battery.
This model can last up to 150 minutes per charge, depending on the strength of the power suction used. According to the manufacturer, it should be able to tackle 2152 sq. feet of space on a single charge
Virtual Barriers
Roborock E4
All Roborock robot vacuums from the E series have a built-in compass to sense magnetic boundary markers.
Unfortunately, you will have to purchase boundary strips if you wish to make use of this feature.
Noise
Roborock E4
Rated at 70 decibels, the Roborock E4 can be as loud as your grandfather’s old school radio when at its peak. Anyway, the decibel rating lowers down as the suction power decreases.
Mop Function
Roborock E4
The Roborock E4 features integrated mopping that allows you to adjust the water flow of the reservoir as per work preferences. The manufacturer claims the add-on mopping system is now 28% larger compared to other models from the E-series.
Since that’s hard to determine, I just gave the manufacturer the benefit of the doubt. Note that the mopping system is an optional extra. You may or may not purchase it along with the E4.
Frequently Asked Questions
How often will I need to clean or maintain my robot vacuum?
But as a general rule of thumb, you should clean the main brushroll and side spinning brushes regularly with the cleaning tool provided by the manufacturer. The HEPA should be changed every three to four months, depending on the frequency the robot is used. You may also want to check the wheels occasionally for stuck debris.

Conclusion
There aren’t many robot mop-and-vacuum hybrids that live up to their promise.
So, if you are looking for a unit that can suck up a frightening amount of debris in its path and mop up dust and stains in its way, the Coredy R750, Roborock E4, and Roborock E35 should deliver the results you are looking for. I definitely recommend all three cost-effective robot vacuums to you. But in the end, the choice should depend on your cleaning priorities.
While these three models aren’t the best I’ve seen, I guarantee their performance is above average, and what you pay is certainly worth the money. But if you are looking for the creme de la creme, I advise you to invest in a Roomba s9+ and a Braava Jet M6.
