1-Minute Review

Roborock S7 Robot Vacuum and Mop with Sonic Mopping, Strong 2500PA Suction, Multi-Level Mapping,...

The Roborock S7 robot vacuum is worthy of any homeowner’s consideration. While the mopping might not be perfect, it still does a great job when compared to the usual standard of mopping vacuums and removes the need for human intervention.

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

  • Amazing LiDAR navigation
  • Highly versatile and customizable
  • Automatic carpet detection to avoid damages
  • Covers a large floor area both for vacuuming and mopping
  • Limited obstacle detection capabilities
  • Entanglement issues
  • Gets stuck on some tight spots
  • Base is harder to dispose of compared to other models

Looking at the pros and cons, the advantages have the higher ground. Yes, the robot may not have front-obstacle detection such as previous models, but the LiDAR navigation more than makes up for that loss.

Furthermore, the entanglement issue as well as the robot getting stuck in some areas can be easily fixed by minor adjustments in maintenance and home organization. I also love the fact it will be compatible with the upcoming auto empty dock.

Overall, the Roborock S7 is a great buy especially if you need a mix of great mopping, virtual navigation, and selection, as well as efficient vacuuming capabilities.

Let’s take a closer look

How it works

The Roborock S7 works by virtually creating a map layout of the whole room using the LiDAR navigation system. This will serve as the blueprint that will aid in navigation as well as the efficient direction of the robot through the house as it moves logically. You will be able to see the map through the Roborock App on your smartphone.

After the mapping has been completed, the robot will proceed with the cleaning. This involves both the vacuum and mop processes. The vacuum has four different modes to choose from. I like the fact that it has a quiet mode for not-so-powerful suction and lesser noise generation.

It also has a Balanced mode for more general operation, a Turbo mode which maximizes speed, and a Max mode for the strongest suction that the Roborock S7 can do.

The mopping, on the other hand, can be changed to four modes. The closed mode means that the water outlet is sealed, and no water is utilized during the operation. Mild and Moderate uses a calm stream of water while the Intense option makes use of the maximum amount of water output and mopping power.

The robot has a run time of 180 minutes and 5200 mAh of stored energy, meaning that it is suitable for extended levels of cleaning. Not only that, but it is also able to cover a large area of almost around 3000 square feet for vacuuming and 2000 square feet for mopping. This is considered a good coverage compared to most brands in the market.

Roborock S7 Robot Vacuum Performance

In terms of performance, the robot is capable of vacuuming and mopping different floor surfaces. In tests, it performed greatly in wood, concrete, and tiles. The Roborock S7 was able to pick up different materials that were scattered around the area in a very efficient and fast manner.

However, a slight issue can be seen in picking up grainy materials such as sugar and salt. Despite this problem, the Roborock S7 was still able to get around 85% to 90% of the debris used for the experiment.

One thing the robot does that I like is auto-carpet detection. Once a carpet is sensed by the Roborock S7, the brush rollers made for mopping will roll up to avoid wetting the surface. This is a very good feature and I like it since it makes sure that my carpets will not be damp after cleaning.

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

Unlike other robot vacuums which rely on bump sensors to redirect, the LiDAR system allows seamless movement without the need for repeated contact. The Roborock S7 also has a self-charging feature that allows the robot to dock by itself during the low battery.

Limitations

It will not be a good Roborock S7 review without stating the device’s limitations. After all, the robot vacuum-slash-mop might be a great cleaning companion, but it is far from perfect.

The first limitation is one that still exists from last year’s model, the S6, in that any S7 user might notice is that it can get stuck around rugs. This is because of the minimal front-obstacle detection capabilities of the robot that renders the Roborock S7 unable to find minimal clearances.

When this happens, there might be a need to pick up the robot by yourself and remove the hindrance that is causing delays.

Another thing that can restrict the capability of the robot is the brush roller design. Since it does not follow the standard brush roller layout, lots of hair can get stuck in it. In the long run, the silicon roller might get teared if the stuck hair and debris do not get removed. Thus, there might be a need to do constant maintenances to make sure that nothing is stopping the rollers from rotating normally.

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

It needs to be emptied in after every vacuuming and mopping process, and this can be frustrating especially for busy individuals. This restriction can be removed with the help of an auto-emptying dock, which Roborock are working on and will be compatible with the S7.

One last thing that limits the robot is the round design. This makes edges a bit harder to clean, unlike with models that have a D or square-shaped layout such as the Neato Botvac range of the Roomba S9.

Ease of set up and use

Set-up of the robot involves checking the package for complete materials. It should include the manuals, wire, cleaning pad, dock, and robot unit. Remember to find a good spot for the base that is near to a power outlet. This will help the robot in the self-charging initiative.

To start using the device, there is a need to download the Roborock App on either the Playstore for Android devices or App Store for iOS devices. You can then choose to add your robot through a Wi-Fi connection by clicking on the corresponding buttons.

Once the connection has been established, you should enter the Wi-Fi password to confirm that the robot is present. The app will then initialize, and you can select your preferred mode on it. To start cleaning, you can either click the central button on the Roborock S7 or use the app.

As the robot progresses, you will notice that it will create a mapped layout of the vicinity. You can use this feature to create No-go zones and Specified Cleaning Areas. This can all be done thanks to the LiDAR navigation of the robot.

The path that the S7 took as well as other information during the process will be shown for monitoring purposes. Furthermore, it can notify you once it gets stuck so you will be able to pick it up and resume the cleaning process.

Overall, the set-up of the Roborock S7 only takes up to less than 10 minutes, unlike many robot vacuums that may need longer to use for the first time.

Reliability

One of the reliable features that I like with the robot is that the water that the Roborock S7 will spread on the floor while mopping dries very quickly. This means that I don’t need to wait for very long just to use my surfaces again.

VibraRise is also beneficial for any user since the Roborock S7 allows automatic carpet detection. Once a carpet is sensed, the mop brush rollers immediately retract so that the carpet does not get wet. This feature is not present in most robot vacuums in the industry, so the Roborock S7 excels in this part.

Another feature that I appreciate is the Sonic Mopping since it enables the Roborock S7 to scrub at around 3000 rotations per minute and this means a better overall clean in my surfaces. Other models and brands only make use of a dragging brush to imitate the mopping process, but the Roborock S7 takes things further by providing a good dirt removal method.

Ongoing Maintenance

Maintenance of the device involves cleaning the brushes, wheels, dustbin, and filter. To clean the brushes, you need to unlatch and remove the main cover, then take out the brush and clear the bearings of hair and gunk that might be stuck.

For the side brush, there is a need to unscrew it and remove dirt that is stuck. You can return it by tightening the brush in place. The wheel can be removed using a screwdriver and then washed with running water. Remember to dry this part before returning it.

The dustbin simply needs to be opened and the content must be disposed of once it gets full. However, you can also choose to fill the bin with water and shake off the dust that is compacted. Remember to dry the part before returning it.

Lastly, the filter can be cleaned with water and then tapped repeatedly to dislodge dirt that is stuck.

Extra Purchases and ongoing costs

The robot does need any extra purchases to function. Furthermore, the only ongoing costs that you will need are electricity bills for operation. Keep in mind that the robot might need to charge frequently and take this into account.

FAQs

Does it have a self-emptying dock?

The Roborock S7 has no auto-emptying dock as of now. However, the company announced that it will release the module later this year. Specifics are not yet mentioned.

Can the robot go underneath furniture?

Yes, the Roborock S7 can enter anything as long as it has a clearance of around 15 cm or more. This makes cleaning underneath sofas and cabinets possible.

Is the robot noisy?

The robot does make some sound, but not to the point that it will annoy you greatly. It is estimated to fluctuate around 62 to 70 decibels of noise depending on the setting or mode that you choose.

Can the robot work without Wi-Fi?

Yes, the robot can work without Wi-Fi by clicking the start button. However, Wi-Fi is necessary to make full use of the scheduling, mode selection, and virtual mapping features.

What is the coverage of the robot?

The S7 Robot vacuum can handle up to 3000 square feet of vacuuming area and 2000 square feet of mopping area. However, this can change depending on your floor type and chosen cleaning mode.

Conclusion

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

The Roborock S7 is worth the investment since it provides a good clean using a blend of great hardware and software. 

The LiDAR navigation is ahead of other robot vacuums in navigation, and virtual mapping will never get as good as this. Furthermore, it offers great mopping capabilities that can never be seen in other brands and models.

If you are willing to spend some cash on a 2-in-1 mopping and vacuum-ready robot, then this product is for you.

However, if you only want the vacuuming part, you should stick with the Roborock S4 as it has the same benefits as the S7 without the mopping side. This way, you will save a bigger amount of money on your purchase.
