In 2018 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?

The second version is called the Roborock Xiaowa (without "Lite" ending). The Roborock Xiaowa has stronger suction, gyroscope navigation, and wet mopping function. It also can be named as Xiaowa E2, E20, and E25 which is the same model, the only difference in color. The E20 is white, the E25 is dark grey.

The cheapest and only one model that comes without mapping feature is the Roborock Xiaowa Lite. Sometimes sellers can add "C1" or "C10" to the Xiaowa Lite, but it's the same model, just released for different countries and regions.

The Roborock Xiaowa E3 (or E35) is a third generation of the Xiaowa series and has the strongest suction of 2,000 Pa.

What is the same?


The Roborock Xiaowa vacuums 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 E25 and E35 comes in a fabulous dark grey color.

Cleaning Performance & Battery Life

With strong suction power, the robot's battery lasts about 80-100 minutes. 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 cleaning 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.

All the Xiaowa cleaners are equipped with carpet identification that boosts air power to max once the robot is on rug/carpet.


Each of the robots has the same dustbin capacity holding 640ml of dirt.


The Roborock Xiaowa Lite, E2, and E3 come with the Mi Home app. It allows you to manage the robot's movements manually, set the cleaning mode you need, schedule it to work at a specific time, see the battery life, and the accessories level life. The Xiaowa (E2) and E3 support to watch they create a map in real-time.

What is the difference?

Battery Life

The oldest and cheapest version works for 80 minutes; the Xiaowa (E2) is able to last up to 100 minutes; the latest Xiaowa (E3) is a beast that cleans for the whole 150 minutes until it needs to recharge.

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 1,670 Pa suction, even the budget Roborock Xiaowa Lite does as good a job on carpets the same as the more expensive robots.

Mopping Attachment

While the Roborock Xiaowa Lite only sweeps, the newest versions E2 and E3 can also mop. Both come with a water tank and mop cloth that is supposed to work on 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 none 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. It is serviceable as a mop but it's not going to take the place of the traditional mopping though will decrease the amount of time you spend doing it manually.


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 areas where it has already been which reduce operation time because the device will not go to the ones that are already cleaned.

Maybe it is not the most accurate way of mapping, but it does its job well, helping the robot navigate. As was 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 yet you can see it in history cleaning.

Recharge & Resume

Based on a created map, the Xiaowa E2 and E3 is able to remember where it was. The robot can recognize the spot it left off before it returned to its charging base.

When the battery is below 20% of the charge, the robot gets back to juice up its battery up to 80% and resumes cleaning until it's done.

The Xiaowa Lite (C1) does not support continuous cleaning. When its battery needs recharging, the vacuum automatically docks itself to recharge. You can make it clean again by manually pressing start on the robot or inside the app.

Price & Purchasing Details

In the end

The Roborock Xiaowa Lite (C1) is suitable for small homes with mostly carpeted surface. If you are tight on budget and don't need mopping - go with the Lite version.

The Roborock Xiaowa (E2) costs a little bit more offering mopping and mapping. It works a bit longer which makes it more suitable for small and average-sized homes with pets. The robot can clean carpets and bare floor and is ideal for mixed surface.

The Roborock XIaowa (E3) offers one of the strongest suction and long-lasting battery in the industry. It is perfect for big medium and homes with carpets and bare floor. If you have a pet, the Xiaowa E3 would be the best helper that will fight with pet hair regularly.

All of them are worth buying. These are decent machines that have long battery life, beautiful minimalist design, and strong suction power. The Xiaowa model line shows excellent cleaning performance for robot vacuums of such price.

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