The Roborock S6 is a premium robot vacuum. It delivers superb performance on bare floors, and it's equipped with a mopping attachment that can help clean wet spills or stuck-on grime. The vacuum also delivers okay performance on low and high-pile carpet. It offers a wide array of automation features through its companion app, allowing you to set up virtual boundary lines or schedule cleaning sessions for individual rooms. Unfortunately, it has demanding maintenance needs and has many parts that need to be replaced every few months, depending on your usage.

Our Verdict

7.7
Bare Floor 

The Roborock S6 is great for cleaning bare floors. It clears everything from pet hair to bulky debris like cereal with ease. It comes with a mop attachment to clean sticky messes, although we don't currently test it. However, this vacuum does have many parts that require regular cleaning or even replacement. Thankfully, its companion app lets you know which accessories need to be replaced and when.

Pros
  • Effective smart pathing feature.
  • Picks up pet hair on all surfaces.
  • Exceptional performance on bare floors.
Cons
  • Many recurring costs and it requires ongoing maintenance.
6.9
Low-Pile Carpet 

The Roborock S6 is satisfactory for low-pile carpet. While it can pick up dog hair without a problem and clears a decent amount of larger debris like sand, it struggles a lot more with fine debris like baking soda. Thankfully, it does an excellent job of maneuvering itself and offers a wide range of automation features through its companion app. Unfortunately, recurring costs are high, and it also has demanding maintenance needs.

Pros
  • Effective smart pathing feature.
  • Picks up pet hair on all surfaces.
Cons
  • Struggles to pick up small debris.
  • Many recurring costs and it requires ongoing maintenance.
6.5
High-Pile Carpet 

The Roborock S6 is okay for high-pile carpet. While it can easily climb on top of high-pile carpet and maneuver around, it has trouble picking up fine debris like baking soda and larger debris like sand, though it does a fantastic job of cleaning pet hair. This vacuum has many parts that require regular cleaning and incurs high recurring costs.

Pros
  • Effective smart pathing feature.
  • Picks up pet hair on all surfaces.
Cons
  • Struggles to pick up small and large debris.
  • Many recurring costs and it requires ongoing maintenance.
5.3
Pets 

The Roborock S6 is excellent for cleaning up pet hair. It does an excellent job of picking up hair on all surface types and does a good job of filtering out allergens. However, it does need regular maintenance for many components, which also need to be replaced regularly. Luckily, Roborock includes a cleaning tool that can help you detangle hair from the brushroll, which is also removable for easier access.

Pros
  • Picks up pet hair on all surfaces.
  • Removable brushroll.
  • Good air filtration peformance.
Cons
  • Many recurring costs and it requires ongoing maintenance.
5.9

    4.  Updated Aug 03, 2022: Converted to Test Bench 0.6.

    Differences Between Sizes And Variants

    The Roborock S6 is available in two color variants: 'Black' and 'White'. We tested the 'Black' variant, but expect the other color variant to perform similarly overall.

    This vacuum shares much in common with the newer Roborock S6 MaxV and Roborock S6 Pure. The MaxV features additional optical sensors to better identify obstacles. Meanwhile, the Pure is equipped with a larger water reservoir for its mopping attachment and has fewer physical control buttons. However, it should be noted that we haven't tested the Pure yet.

    Let us know in the discussions below if you've come across another variant of this vacuum so that we can update our review.

    Compared To Other Robot vacuums

    The Roborock S6 is a good overall robot vacuum. Just like the Roborock S5, it has a mop attachment so that it can clean sticky messes around the house, although we don't currently test this. Unlike many other robot vacuums, it can also maneuver on and clean high-pile carpet, although it isn't as good at cleaning this surface as the Neato Botvac D7.

    If you're searching for alternatives, you can take a look at our list of recommendations of the best robot vacuums, the best robotic vacuums for hardwood floors, and the best robot vacuums for carpets.

    Roborock S7

    The Roborock S7 is better for most uses than the Roborock S6, though they each have their own advantages. The S6 has a bigger dirt compartment, is a little lighter, and takes less time to charge while offering a similar overall runtime. Conversely, the S7 is more effective on carpets and has a more advanced mopping function, which does a better job of scrubbing away stains and can be raised when the vacuum is maneuvering on carpets. The S7 is also fully compatible with a self-emptying dock.

    Roborock S5

    The Roborock S6 is a slightly better robot vacuum than the Roborock S5. The S6 has a similar mopping feature, but it comes with disposable mopping cloths, so you don't have to worry about it dragging messy spills around the house. In terms of performance, it also does a better job with small and large debris as well as pet hair on any surface type. It has slightly better maneuverability, and it feels a better built. That being said, both vacuums have very similar battery life.

    Roborock S6 MaxV

    The Roborock S6 MaxV and the Roborock S6 are similar vacuums, and you may prefer either one, depending on your preferences. The S6 delivers a better cleaning performance on every surface type and has a longer battery life. However, the S6 MaxV has a 'ReactiveAI' feature that uses cameras on the front of the vacuum to detect obstacles and move around them. It's also slightly smaller. Both models come with mopping attachments, but we don't test that feature currently.

    Roborock S4

    The Roborock S6 is a better robot vacuum than the Roborock S4. The S6 cleans all surface types much better, especially because it can climb onto high-pile carpets, and it has a mopping feature, although we don't currently test for this. It also has slightly better maneuverability and build quality. That being said, the battery life of both vacuums is very similar, so if you don't have carpet in your home, the S4 could be a good alternative.

    The Roborock S6 has excellent build quality. It's made of high-grade plastic and has some metallic accents that give it a premium look. Its durable rubber wheels help the vacuum climb up onto high-pile carpet. Its glossy-finish top cover can be lifted to access the dirt compartment, the Wi-Fi indicator light, and the system reset button. There are also three buttons on its top so you can control it without using the app. Compared to the Roborock S5, it uses a five-pronged side brush which is made of silicone and plastic and has a brushroll with longer, softer bristles. Its mopping attachment can be used to help clean your floor of built-up grime, but we don't currently test for this.

    This vacuum is pretty easy to set up out-of-the-box, requiring only that you pair it with the charging dock and connect it to the Mi Home or Roborock apps if desired.

    6.5
    User Maintenance

    The Roborock S6 robot vacuum is somewhat difficult to maintain, and a lot of its parts need ongoing maintenance.

    • Brushroll: The brushroll can be accessed by taking off the plastic cover underneath the vacuum and then pulling it out. It comes with a cleaning tool that has a brush on one end and a hook blade on the other end so that you can cut hair from the brushroll. The brushroll needs to be cleaned once or twice a week, depending on your usage.
    • Side brush: You need a screwdriver to remove this brush and to screw it back into place. It needs to be cleaned once a month.
    • Dirt compartment: The dirt compartment can be accessed by lifting up the top cover then pulling it out. It needs frequent emptying due to its size and can be washed out with water, but make sure that it's fully dried before using it again.
    • E11 Filter: The filter is found inside the dirt compartment. You need to unclip it from the compartment in order to remove it. It should be washed every two weeks. Make sure to let it dry completely before reinstalling it.
    • Wheel: The omnidirectional wheel located at the back of the vacuum can be simply pulled from its socket. That said, it requires some effort to do so, so you may want to use a pair of pliers. You should clear it of any stuck-on debris once a month.
    • Sensors: If there's dust and debris building up on the sensors, you can wipe them down with a dry cloth.
    • Mop attachment: We don't currently test for this but the mopping cloth needs to be cleaned after each use.
    • Disposable mop cloth: We don't currently test for this either but the disposable mopping cloth should be discarded after every use.
    • Water tank filter: If you're using the mopping attachment, you need to replace this filter every one to three months.

    The Mi Home app lets you know which parts need to be replaced based on the total hours used. This is only for when you need to buy a new part and not clean a specific piece.

    Recurring Cost
    Bag Part NumberNo bag
    Filter Part NumberE11
    HEPA Filter Part NumberNo HEPA Filter

    The Roborock S6 has many recurring costs.

    • Brushroll: The brushroll should be replaced every six to 12 months, or after 300 hours of use.
    • Side brush: The side brush should be swapped out ever three to six months, or after 200 hours of use.
    • E11 Filter: The E11 filter has an estimated service life of three to six months, or after 150 hours of use.
    • Mop attachment: We don't currently test for this but the mopping cloth needs to be replaced every six to 12 months.
    • Disposable mop cloth: We don't currently test for this either but the disposable mopping cloth should be discarded after every use.
    • Water tank filter: We don't currently test for this, but you need to replace this filter every one to three months.

    These parts are available from Roborock's Amazon store. Its companion app has a 'Maintenance' tab which gives you a rough estimate of each parts' remaining service life.

    The Roborock S6 has a decently-sized dirt compartment. It doesn't have a physical dirt compartment indicator, so you need to either constantly monitor it or let the companion app remind you after you run multiple cleaning jobs. If you don't want to worry about the compartment filling up, you can also empty it after each use, though its overall capacity is larger than that of the Roborock S7.

    The Roborock S6 has outstanding battery performance. An indicator light on its top gives you a rough estimate of the remaining battery life. When the light is white, the battery is above 20%, and when it's lit red, the battery has less than 20% charge left. On its most powerful 'Max' mode, it lasts just under two hours, and on its least powerful 'Silent' mode, it supplies slightly over three hours of runtime, which is similar to the Roborock S5. However, this can vary in the real world. If the vacuum's battery drops below 20%, it abandons its current cleaning task and returns to its charging dock.

    The Roborock S6 has a few extra features. It has four different suction power modes: 'Silent', 'Balanced', 'Turbo', and 'Max'. It can also automatically adjust to the surface type it's on by changing its brushroll's speed. When it gets near walls and edges, it spins faster to pick up more debris, while if it's in the middle of a room, it spins slower to prevent debris from getting picked up. Unlike other Roborock vacuums, the Roborock S6 also has a carpet mode that can be turned on/off on the app, which allows the robot to automatically change its power mode when cleaning carpet.

    The Roborock S6 has a side brush to direct debris from the outside of the vacuum towards its main brushroll. It comes with a small hook blade to help cut hair away from the brushrolls. There are also two reusable mop mats as well as a mop water container that can be used to clear sticky messes or grime on bare floors. Unlike the Roborock S5, it comes with 10 disposable mop cloths that you can throw away after a cleaning job. There's also a mounting plate that allows you to attach the disposable mop cloths to the water container, but we don't currently test this feature.

    The Roborock S6 has exceptional performance on bare floors. It can easily capture pet hair and small debris like rice. Unlike the iRobot Roomba i7, it can also pick up a lot of bulky debris like cereal. However, some of this debris can get stuck in the tunnel between the brushroll and the compartment.

    The Roborock S6 is okay on low-pile carpet. It does a fantastic job of cleaning pet hair, but it struggles a bit more with large debris like sand and has an even harder time with fine debris like baking soda. Consider the iRobot Roomba S9 if you're looking for a robot vacuum with better performance on this kind of surface.

    The Roborock S6 delivers fair performance on high-pile carpet. While it picks up pet hair with ease, it equally struggles to clean fine and large debris like baking soda or sand, and it can take several passes for it to fully clean this surface type. If you're looking for a robot vacuum with slightly better high-pile carpet performance, check out the Neato Botvac D7.

    Maneuverability

    The Roborock S6 has excellent maneuverability. It uses laser sensor navigation to move around effectively and map its coverage area, and it can use smart pathing to become more efficient with each cleaning job. Its small size allows it to get underneath couches or tables, but it gets stuck on tassels and pulls electrical cords around. Luckily, you can use its companion app to set up virtual boundary markers that the vacuum won't cross.
