Roborock S7 Review || Mopping Robot Vacuum

The Roborock S7 Robot Vacuum Cleaner is a 2-in-1 vacuum and scrubbing device with great suction power and virtual mapping capabilities. It has unique LiDAR (Light Detection and Ranging) hardware, located on the top of the robot, to take care of precise navigation. And not only that, but it is also prepared for an application and voice control to offer the best user experience.

On the Internet, people praise this robot for the innovations it brings to any home. In this Roborock S7 review, we’ll take a look at the robot’s pros, cons, performance, limitations, and how it works to see if it deserves the praise and is among the best robot vacuum cleaners on the market.

Main Thing – Fast Review

roborock s7 robot vacuum is the best robot vacuum cleaner

The Roborock S7 robot vacuum deserves the consideration of any owner. Even if the scrubbing isn’t perfect, it still does a great job compared to the usual standard of vacuum cleaners for scrubbing and eliminates the need for human intervention.

When it comes to vacuuming, the robot is one of the best around thanks to its strong suction that can pick up any type of dirt that has stuck to your floors. The virtual mapping and application control is also top-notch and polished, and this makes the Roborock S7 Robot Vacuum Cleaner a strong competitor in the robot vacuum market.

If we analyze the pros and cons, the advantages are greater. Yes, the robot may not have frontal obstacle detection like previous models, but the LiDAR navigation more than makes up for that loss.

In addition, the problem of tangles, as well as the fact that the robot gets stuck in some areas, can be easily solved with small adjustments in the maintenance and organization of the home. I also love the fact that it will be compatible with the upcoming self-emptying dock.

Overall, the Roborock S7 is a great buy, especially if you need a mix of great scrubbing, virtual browsing, and sorting, as well as efficient suction capabilities.

  • Amazing LiDAR navigation
  • Very versatile and customizable
  • Automatic carpet detection to avoid damage
  • Covers a large floor area for both vacuuming and scrubbing
  • Limited obstacle detection capabilities
  • Tangle problems
  • It gets stuck in some narrow places
  • The base is more difficult to dispose of compared to other models

Complete Review of the Roborock S7 Robot Vacuum

How does it work

The Roborock S7 works by virtually creating a map of the entire room using the LiDAR navigation system. This will serve as a blueprint that will aid in efficient navigation and direction of the robot around the house while moving logically. You can see the map through the Roborock application on your smartphone.

Once the mapping is complete, the robot will proceed to clean. This involves both the vacuuming and scrubbing processes. The vacuum cleaner has four different modes to choose from. I like that it has a quiet mode for less powerful suction and less noise generation.

It also has a balanced mode for more general operation, a turbo mode that maximizes speed, and a maximum mode for the more powerful suction the Roborock S7 can do.

The mop, for its part, can be switched to four modes. Closed mode means that the water outlet is sealed and no water is used during operation. The Gentle and Moderate modes use a calm stream of water, while the Intense option uses the maximum amount of water output and scrubbing power.

The robot has a run time of 180 minutes and 5200 mAh of stored energy, which means that it is suitable for long cleaning levels. Not only that, but it is also capable of covering a large area of ​​nearly 3,000 square feet for vacuuming and 2,000 square feet for scrubbing. This is considered good coverage compared to most brands on the market.

Roborock S7 review helps you to know multi-function facility


In terms of performance, the robot is capable of vacuuming and scrubbing different floor surfaces. In tests, it performed very well on wood, concrete, and tile. The Roborock S7 was able to collect different materials that were scattered around the area in a very efficient and fast way.

However, there is a slight problem when collecting granulated materials, such as sugar and salt. Despite this problem, the Roborock S7 was able to collect between 85% and 90% of the waste used in the experiment.

One thing the robot does that I like is automatic carpet detection. Once the Roborock S7 detects a carpet, the scrub brush rollers roll up to avoid wetting the surface. It’s a very good feature and I like it as it ensures that my rugs won’t be damp after cleaning.

Compared to other Roborock models, thanks to the sonic scrubbing technology, the Roborock S7 has one of the best scrubbing capabilities.

Unlike other robot vacuum cleaners that rely on shock sensors to redirect, the LiDAR system allows fluid movement without the need for repeat contact. The Roborock S7 also has a self-charging feature that allows the robot to dock on its own when it runs out of battery.

It would not be a good review of the Roborock S7 without indicating the limitations of the device. After all, the robot vacuum scrubber can be a great cleaning companion, but it is far from perfect.

The first limitation is one that continues to exist from last year’s model, the S6, in which any S7 user may notice that it can get stuck around carpets. This is due to the robot’s minimal frontal obstacle detection capability, which makes the Roborock S7 unable to find minimal gaps.

When this occurs, it may be necessary to lift the robot by itself and remove the obstacle that is causing delays.

Another thing that can restrict the robot’s ability is the design of the brush roller. As it does not follow the standard arrangement of the brushing rollers, many hairs can get stuck in them. Eventually, the silicone roller could break if stuck hair and debris are not removed. Therefore, constant maintenance may be necessary to ensure that nothing is preventing the rollers from rotating normally.

The small trash can, with a capacity of 470 ml, can also be a bane for many users, as it limits the total operating power of the device.

It needs to be emptied after every vacuuming and scrubbing process, and this can be frustrating especially for busy people. This restriction can be removed with the help of an automatic drain spring, which Roborock is working on and which will be compatible with the S7.

One last thing that limits the robot is its round design. This makes the edges a bit more difficult to clean, unlike models that have a D-shaped or square arrangement, like the Neato Botvac range of the Roomba S9.

Setup and use

Assembling the robot involves checking that the package is complete. It should include the manuals, cable, cleaning pad, base, and robot unit. Remember to find a good place for the base that is close to an electrical outlet. This will help the robot in the self-loading initiative.

To start using the device, you need to download the Roborock application from the Playstore for Android devices or from the App Store for iOS devices. You can then choose to add your robot through a Wi-Fi connection by pressing the corresponding buttons.

Once the connection is established, you must enter the Wi-Fi password to confirm that the robot is present. The application will then initialize and you can select the mode you prefer. To start cleaning, you can press the central button of the Roborock S7 or use the app.

As the robot progresses, you will see that it will create a map of the surroundings. You can use this function to create prohibited zones and specified cleaning areas. All of this can be done thanks to the robot’s LiDAR navigation.

The path the S7 has followed, as well as other information during the process, will be displayed for you to track. Plus, it can alert you when it gets stuck so you can pick it up and resume the cleaning process.

In general, the Roborock S7 only takes less than 10 minutes to set up, unlike many robot vacuums that may take longer to use for the first time.


One of the reliable features that I like about the robot is that the water that the Roborock S7 spreads on the floor when scrubbing dries very quickly. This means that I don’t have to wait long to use my surfaces again.

VibraRise is also beneficial for any user, as the Roborock S7 enables automatic carpet detection. Once a carpet is detected, the mop brush rollers immediately retract so the carpet does not get wet. This function is not present in most robot vacuum cleaners in the sector, which is why the Roborock S7 excels in this part.

Another feature I appreciate is the sonic scrub, as it allows the Roborock S7 to scrub at around 3,000 rotations per minute, which is a better overall cleaning of my surfaces. Other models and brands only use a drag brush to mimic the scrubbing process, but the Roborock S7 goes above and beyond by providing a good soil removal method.

Roborock S7 has multi-level mapping functionality


Maintaining the appliance consists of cleaning the brushes, wheels, dustbin, and filter. To clean the brushes, you have to unhook and remove the main cover, and then take out the brush and clean the bearings of hair and dirt that may be stuck.

For the side brush, you have to unscrew it and remove the dirt that is stuck. You can put it back in by squeezing the brush in place. The wheel can be removed with a screwdriver and then washed under running water. Remember to dry this piece before returning it.

The trash can only needs to be opened and the contents must be disposed of once it is full. However, you can also choose to fill the bucket with water and shake off the compacted powder. Remember to dry the piece before returning it.

Finally, you can clean the filter with water and then tap it repeatedly to loosen any dirt that has stuck.

Additional purchases and charges

The robot does not need any extra purchase to function. Also, the only ongoing costs you will need are electricity bills for its operation. Please note that the robot may need to be changed frequently and keep that in mind.

Roborock is a great brand and a great alternative to a Roomba. Once again, they have not let us down.

The Roborock S7 is worth the investment as it provides a good cleaning using a mixture of great hardware and software. LiDAR navigation is ahead of other robot vacuum cleaners when it comes to navigation, and virtual mapping will never be as good as this one. In addition, it offers a great scrubbing capacity that cannot be seen in other makes and models. If you are willing to spend some money on a 2-in-1 scrubbing and vacuuming robot, this product is for you.

However, if you only want the vacuum part, you should stick with the Roborock S4, as it has the same performance as the S7 without the scrubbing part. In this way, you will save a greater amount of money on your purchase.
