Not that long ago, Roborock released its budget robot vacuum cleaner - the Roborock Xiaowa Lite. We have already compared it with the flagship model - Roborock S5, where we talked about why you might prefer the cheapest version, the Roborock Xiaowa Lite over the Roborock S5. But suddenly, the newest Roborock Xiaowa E20 and E35 show up and bring some new features we'd like to talk about. So here we go: what is the difference between the two beasts and why both are worth buying?

What is the same?


Both build the same way. The Xiaowa keeps the typical Roborock minimalist style coming in a black and white color combination and only three small buttons on the lid. The dustbin is hiding under the lid and is easy to pull out. Underneath you will find a side sweeper and bristle brush. Along with this, the Xiaowa has two large wheels that allow the robot to cross a slope up to 20mm in height. There are sensors located all over the machine's body preventing it from falling by detecting obstacles. Overall, the Xiaowa looks fantastic! The newest Roborock Xiaowa E35 comes in an amazing dark grey color.

Cleaning Performance & Battery Life

With strong suction power, the robot's battery lasts up to 120 minutes, a rare thing considering its price. The latest Xiaowa E35 works for the whole 150 minutes as long as the flagship Roborock S5 does.

Along with a powerful motor, the side brush sweeps all the dust and dirt, while the main brush helps scratch it from the floor, then transferring the mess to the dust box. The suction power is strong enough for ridding thin and medium-pile carpets of pet hair, leaving your floors clean. The Xiaowa also works great on a bare floor catching every small particle in its path.


Both robots have the same dustbin capacity holding 640ml of dirt.


Both models come with the Mi Home app. It allows you to manually manage the robot's movements, set the cleaning mode you need, schedule it to work at a specific time, see the battery life, and the accessories level life. Also, the latest version allows viewing a created map.

What is the difference?

Suction Power

As you might notice, the Xiaowa (E20) version delivers 1,800 Pa while the Lite model - 1,600Pa. The newest Xiaowa E35 has 2,000 Pa of suction. Each of the robots performs great on a bare floor; the more powerful one cleans carpets slightly better. Because even the flagship Roomba 980 has a 1,670Pa suction, the Roborock Xiaowa Lite does as good a job on carpets as the more expensive robots.

Mopping Attachment

While the Roborock Xiaowa Lite only sweeps, the newest versions E20 and E35 can also mop. Both come with a water tank and mop cloth that is supposed to wet mop a bare floor. When the robots do not move, the water doesn’t drip. Please note that if you want to clean stubborn stains, you'd better go with something like the Xiaomi Handheld Electric Mop because no one robot mop can do this at least at this moment. In any case, the mopping attachment is perfect for tile, laminate, marble or hardwood floors, and it will keep them clean and fresh.


The newest versions Xiaowa E20 and E35 map the area where it has cleaned, but not in the same way we are used to. It does not have a laser or camera sensor like other smart machines. So how does the Xiaowa manage to create a map? It is equipped with a dual-gyro inertial navigation system and the German six-axis BOSCH gyroscope. It also has a dual-optical laser + a LED motion tracking sensor. When it works, it slightly bumps into obstacles, so its sensors "remember" the position of each, including chairs legs, walls, and basically everything it has touched. With this technology, the robot can identify places where it has already been which reduce operation time because the device will not go to the zones already cleaned.

Maybe it is not the most accurate way of mapping, but it does its job well, helping the robot navigate As mentioned before, you can check the created map on your smartphone. After the Xiaowa finishes the cleaning, it will not hold the map in memory meaning that the robot creates a new map every time it works.

Price & Purchasing Details

In the end

All of them are worth buying. These are decent machines that have long battery life, beautiful minimalist design, and strong suction power. They are ideal for a small, average home with pets, and are suitable for a mixed-surface home or household with a bare floor and mostly carpeting.

It depends on your own preferences and budget; thus, it's up to you to decide which model to go with.
