Robot vacuums have been with us for a while now and although the idea of a vacuum cleaner that worked autonomously sounded very futuristic when they were first released, we have come to accept them as ordinary devices that every home should have.

Roborock E25 vs. E35 Robot Vacuum and Mop

On the other hand, robot manufacturers are always working on new improvements that are going to amaze buyers and make them feel like they are buying truly futuristic devices. One such improvement is the addition of mopping capabilities to robot vacuums.

This is the case with the Roborock E25 and the Roborock E35 – the two devices that we will be comparing today. Both these robots are made by Xiaowa, a brand that may not sound as familiar as iRobot, Neato Robotics, and Dyson in the world of vacuums.

Both these robot vacuums are in the mid-budget range and they do quite an amazing job of cleaning the various floor surfaces in your home. The E35 comes with a bit more suction, a stronger battery and as expected, a slightly higher price tag.

Let’s take a closer look at the similarities and differences between these two devices to try and establish which one will give you the best value for your money.

Cleaning Performance

The main duty of a vacuum and mop robot is to clean your floors. Unless it can effectively clean your floors, any other feature – no matter how impressive it may be – will not make any difference. It will simply be useless because of the inability to accomplish the one task it was bought to accomplish.

Let’s take a look at how each of these devices performs when it comes to cleaning your floors.

Roborock E25
As mentioned earlier, this is the simpler model of the two, so it comes with slightly lower numbers when it comes to performance. For starters, the motor in the robot can deliver 1800Pa of suction which may not sound like a lot when you place it side by side with other more powerful models, but you will hardly notice any insufficiencies when you send it on its way to vacuum your home.

You will also be happy to know that the robot will automatically detect when it reaches a carpeted area and step up the suction so that it can perform deeper cleaning. Once it leaves the carpeted area, it will automatically lower the suction to ensure maximum runtime.

This robot vacuum and mop has six cleaning modes that will make sure that you get the perfect selection for your needs. You can choose between mopping mode, carpet mode, quiet mode, balanced mode, turbo mode, and max mode. Together, these modes make sure that you have the perfect solution for your specific needs.

You can also set this robot to vacuum and mop your floors as it moves along simultaneously. This way, any small particle that couldn’t be picked up by the suction will be wiped away by the moist mopping pad. This mopping pad has been designed to suck in water evenly and gradually as the pad dries to ensure that no puddles are left on the floor.

This vacuum is also very similar to the E25. It also comes with six cleaning modes to ensure that you find the perfect solution for your cleaning needs. You can also tell it to simultaneously mop and vacuum to ensure that your hard floors are left spotless.

The motor on this robot is more powerful than that on the E25, so it will be able to deliver up to 2000Pa. This is more than enough suction to pick up particles of all sizes both on carpets and hard floors. To ensure that you can reap the full benefits of this suction without sacrificing the runtime, it comes with the Carpet Boost feature that steps up the suction when the robot reaches a carpeted area, and it brings it back down after it clears the carpeted area and goes back to a hard floor.

When it comes to navigation, these two vacuum robots are pretty similar. It seems like they use the same technology on both vacuums and this makes sense because the difference in price is not that big.

Both vacuums will clean your house systematically following straight lines to ensure fast and efficient cleaning. They have 13 motion tracking sensors that help in ensuring that the robots don’t fall off the stairs, collide with any obstacles present along their paths and also in ensuring that the robots don’t end up trapped.

Voice control is possible on both the E25 and the E35 by pairing with an Amazon Alexa device. If you’d rather do it the old fashioned way, you will need to download the Mi Home app, and it will allow you to set schedules, start, stop, and pause cleaning runs, get progress notifications, and much more.

Filtration Efficiency

Both these robots use the same filter, which is a high-efficiency E11 filter that is rated to capture up to 99.2% of particles as small as 0.3 microns. This means that it will be able to catch dust mites, mold spores and other small allergens that can make life difficult if you suffer from allergies.

It’s also a washable filter so you can be happy because replacement costs will be kept at a minimum.

Battery Life

Unlike the filter and navigation technology, the battery on these two vacuums is different. As expected, the E35 comes with more battery life than the E25. The good news is that both robots come with the Recharge and Resume feature which enables them to pick up from where they left off if they ever run out of charge before finishing the cleaning job.

The battery on the E35 provides enough juice to power the robot for up to 150 minutes, while the one on the E25 will give enough juice for up to 100 minutes.

Roborock E25 Review


With a stronger battery and more powerful suction, the Roborock E35 seems to give better value for money. It may be slightly more expensive than the Roborock E25, but the difference is typically not that big. The fact that both these vacuums come with mopping capabilities and features like recharge and resume that you normally find on expensive high-end models means that you are not likely to regret your choice whichever way you choose to go.
