REVIEW – The floors in my home are carpeted with Berber carpet with the exception of the kitchen and bathrooms which are tiled. We vacuum every day, and for the past few years, we have been using the Dyson V6. The Dyson works quite well, but over time I have grown tired of this chore which I usually do at night when I return home from work, and when the kids are in bed and can no longer make a mess, at least until they wake up next the next morning. Recently, I was offered the opportunity to test and review the Roborock E20 Vacuum Cleaner and I readily accepted. Here is my summary!!

What is it?

The Roborock E20 Vacuum Cleaner is an efficient vacuum with built-in Artificial Intelligence. It works quickly and efficiently with 1800Pa of suction power and uses a dual-gyro system, and motion tracking sensors to create a high-efficiency cleaning path for every room. There are 13 onboard sensors to provide drop avoidance, anti-collision, trap prevention, self-charging, and resumption. It is able to vacuum and mop and with the use of the relevant app it can be controlled to start, stop, schedule, customize, charge, spot clean, check accessory status, and control movement direction. It is able to switch/increase its suction power automatically when it transitions from wood floors to carpet, and if it runs low on power it returns to its dock to recharge then resumes where it left off. It communicates with the app via 2.4GHz Wi-Fi and has a 2600mAh lithium battery for a long-lasting charge.

Design and features

Methodical cleaning: Dual-gyroscopes and high-precision optical tracking sensors allow E20 to clean methodically around a room, starting around the edge then the areas in between.
Intelligent systems: A full suite of sensors gives E20 the intelligence to effectively tackle complicated environments without falling off ledges, getting stuck, or running out of power.
Tangle Free: All brushes and wheels are designed to be tangle free, eliminating the need to open E20 robotic mop for cleaning. An included cleaning accessory can be used to remove hair from the outside of the cleaner making it perfect for picking up after your pets.
Obstacle crossing: Able to clamber up over obstacles as high as 0.8in, E20 easily handles thresholds, thin carpets, and other low barriers.
Carpet boost: When a carpet is detected, suction is increased to maximum to pull up deeply lodged dirt. Once off the carpet, normal suction returns.
Washable Filter: A high-efficiency E11 filter captures 99.2% of dust and allergens, down to just 0.3 microns. Its washable design extends its life and reduces replacement frequency.
Holiday Mode: In this mode, the LED indicator will dim, functions that have nothing to do with charging such as cleaning, recharging and remote control via wifi will be disabled, and the cleaner will enter low power consumption mode to maintain optimal battery performance.


When you open up the cover on the top of the vacuum, you find the removable dust canister.

On the removable dust canister, there is a removable filter that attaches to the canister and prevents dust and debris for entering the suction chamber of the vacuum. The filters are actually washable and they provide two so that you can use the second while the first dries.

On the surface of the vacuum, there are 3 touch buttons. From left to right they are the spot cleaning button, the clean/on/off button and the recharge button. To reset the WiFi, you press and hold the spot cleaning and recharge buttons simultaneously for 3 seconds. The knob that is seen above the 3 touch control buttons is the omnidirectional recharge sensor.

If you look carefully at the picture below, you will see a small LED in the upper right-hand corner of the canister compartment. This LED is the WIFI indicator.

On the circular sides of the vacuum, there are two visible grilles. In the picture shown below, the grille on the left is the speaker, and on the right is the air outlet.

Underneath the vacuum, there is the main brush and suction port in the center, an extended 3-prong brush off to the side that allows the vacuum to brush square corners and to move dust into the path of its suction port, and the 3 wheels that it uses to maneuver. The diagram below the photo shows the details.

The picture below shows the docking mat that attaches to the charging dock. The vacuum rests on this mat when charging and when docked. The second row of pictures below shows the charging dock and the AC port located on its side.


This vacuum was basically a plug and play exercise, and it works very well. Initially, I did not find any clear instructions regarding the app, but I soon figured that I needed to download the Mi Home app which seems to recognize and control all AI devices within the Xiaomi device family. The Vacuums mapping ability is great and I am pretty sure that it does a better job of coverage than I do when using a handheld vacuum. I  like the options to regulate the suctioning power and that even when it is at full power, its noise level is much lower than a conventional vacuum. Here is a short video of it performing. I included the ambient sounds for reference.

The following are some of the screens from the app:

What I like

  • The size
  • The built-in technology
  • The overall vacuuming performance
  • Its ability to know when it has finished vacuuming or when it is low on power and automatically return to its base
  • The versatility that makes it adaptable to multiple surfaces
  • The app and its ability to control the vacuum for anywhere

What can be improved

  • Since there are no clear instructions regarding the app, maybe they can add QR Codes for IOS and Android to their manual
  • I don’t know. Maybe it can learn to bring me dinner?
  • Possibly makes me lazy? (lol)

Final thoughts

Initially, I was very excited to test and review this robot vacuum, but I was really not sure what to expect. I was unsure of its ability to really vacuum effectively in regards to sucking up dist and debris, and if it could do a good job of properly vacuuming the entire area. I have to say the I am more than pleased with this vacuum and so much so that my Dyson now resides in the closet and has been reassigned to cleaning furniture and other items/areas that the robot vacuum can’t. I give this vacuum two thumbs up and then some!!! Well done!!

  2. Still using my ~5ish year old Neato. I thought it had come to the end of it’s life couple months ago. But New batteries, filters and rollers (like $40 total) has brought it back to life. Tho I am considering a new one for the second floor of house. As my little Robot Vacuum hasn’t gathered up the courage to climb the stairs yet.

  3. Can’t find the dock for Roborock E20 Robot Vacuum Cleaner. Can you help? The phone number for the company on Amazon lists my area code, 831, for Monterey County, CA. So I doubt it’s correct. Is there a way to contact the company?
