The Roborock S6 is a good overall robot vacuum. Just like the Roborock S4 and Roborock S5, it has a battery life of between two to three hours depending on its suction levels. It can easily clean all kinds of debris on bare floors, and even though it struggles with both small and large debris on carpet, it still does an alright job overall. It also has a mop feature that can help clean wet spills or stuck-on grime; however, we don't currently test this. Its low size allows it to maneuver easily under tables or couches, and it's light enough for you to carry it to another floor for cleaning. On the downside, it has demanding maintenance needs and parts of it need to be replaced every few months, depending on your usage.

Our Verdict

8.4 Bare Floor

The Roborock S6 is great for cleaning bare floors. It cleans everything from pet hair to small and large debris easily, and there's even a mop attachment to clean sticky messes, although we don't currently test it. However, this vacuum requires a bit of maintenance, but at least 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.
7.0 Low-Pile Carpet

The Roborock S6 is alright for low-pile carpet. While it can pick up dog hair without a problem, it struggles a lot more with small and large debris. Even though it has excellent maneuverability, it may take several passes to clean this kind of carpet. It also has demanding maintenance needs.

Pros
  • Effective smart pathing feature.
  • Picks up pet hair on all surfaces.
  • High suction 'Carpet' mode available through companion apps.
Cons
  • Struggles to pick up small debris.
  • Many recurring costs and it requires ongoing maintenance.
6.7 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 small and large debris and it can take several passes for it to fully clean an area. It's much better at picking up pet hair. That being said, this vacuum requires a lot of maintenance.

Pros
  • Effective smart pathing feature.
  • Picks up pet hair on all surfaces.
  • High suction 'Carpet' mode available through companion apps.
Cons
  • Struggles to pick up small and large debris.
  • Many recurring costs and it requires ongoing maintenance.
8.8 Pets

The Roborock S6 is outstanding for cleaning up pet hair. It does an excellent job of picking up hair on all surface types, which is great. However, it does need ongoing maintenance for each accessory. Luckily, Roborock includes a cleaning tool that can help you detangle hair from the brushroll if necessary.

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

Build Quality

The Roborock S6 has an outstanding build quality. It's made of premium hard plastic and it has some metallic touches that give it a sleek look. Its durable rubber wheels help the vacuum climb up onto high-pile carpet. When you remove its silver glossy top cover, you have access to the dirt compartment, as well as the Wi-Fi indicator light, and 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. The brushroll also has longer, softer bristles. It can turn into a mop and it uses a water compartment as well as mopping cloths to help clean your floor, but we don't currently test for this.

This vacuum is pretty easy to set up. All you need to do is set it up with the charging dock, and if you want, connect it to the Mi Home or Roborock apps.

User Maintenance

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

  • Brushroll: The brushroll is removable as you just need to take off the plastic cover underneath the vacuum. 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 is easy to remove. It needs frequent emptying due to its size and you can wash it out with water, but it needs to be fully dry before using it again.
  • Filter: The filter is found inside the dirt compartment. You need to unclip it from the compartment in order to remove it. The HEPA filter needs to be washed every two weeks.
  • Wheel: The omnidirectional wheel located at the back of the vacuum can be removed but it requires significant force to get it out. It helps your vacuum move more smoothly, so it's good to clean it 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.

The Roborock S6 has a few recurring costs but if you need to replace anything, each part is available from Roborock's Amazon store. Its companion app has a 'Maintenance' tab which can tell you the number of hours left before each accessory needs to be replaced or changed. If you maintain each part regularly, Roborock recommends changing the washable filter as well as the side brush every three to six months. The main brushroll also needs to be replaced every six to twelve months. However, all of this depends on your usage.

Note 07/14/2020: Although we don't test for it, the mopping attachment needs to be replaced every six to twelve months, and its water filters need to be changed every three to six months. The disposable mop cloths should be discarded and replaced after every use.

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.

The Roborock S6 has a similarly outstanding battery performance as the Roborock S5. The Roborock S6 has a power button light on its top that gives you a rough estimate of 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% left. On its most powerful 'Max' mode, it lasts just under two hours, and on its least powerful 'Silent' mode, it can vacuum for slightly over three hours. However, if the vacuum's battery reaches below 20%, it won't clean anymore and it heads back to its charging dock.

The Roborock S6 has a few extra features. It has four different modes: 'Silent', 'Balanced', 'Turbo', and 'Max', which all change the suction power. 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 main brushroll as well as a side brush to pick up debris in harder to reach places. It comes with a small hook blade to help cut hair away from the brushrolls. It also comes with two reusable mop mats as well as a mop water container so that it can wipe the floor. Unlike the Roborock S5, this feature additionally includes 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's able to easily capture pet hair and small debris. Unlike the iRobot Roomba i7+, it's also able to pick up a lot of large 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 an excellent job cleaning pet hair but it struggles a bit more with large debris, and has an even harder time with small 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.

Just like the Roborock S5, the Roborock S6 can climb onto high-pile carpet and clean it. However, it does an unremarkable job of cleaning this surface. While it picks up most pet hair, it equally struggles to clean small and large debris, and it can take several passes for it to fully clean this surface type. If you're looking for a robot vacuum with a bit better of a performance on high-pile carpet, check out the Neato Botvac D7.

The Roborock S6 has excellent maneuverability. It uses laser sensor navigation to move around effectively, 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 set up barriers to keep the vacuum from running into these objects by using the companion apps.

The Roborock S6 has excellent automation features. You can either use the Mi Home or Roborock apps to change automation features as well as to access additional features not available when using its top buttons. You can set boundaries and schedule cleaning times for specific rooms. You can also see when different parts need maintenance, check your cleaning history, and even activate 'Carpet' mode to increase suction for these surfaces. If you don't want to use the app, there are buttons on the top of the vacuum to control it. Pressing the 'Clean' button enables a full house clean, the 'Spot Clean' button enables it to clean a small area, and the 'Recharge' button sends the vacuum back to its dock.

Compared to other 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. However, this vacuum comes with disposable mop cloths so you can just throw the cloth away when you're done a cleaning job. Unlike many other robot vacuums, it can also maneuver and clean high-pile carpet, although it isn't as good at cleaning this surface as the Neato Botvac D7.

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 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 carpet, 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.

iRobot Roomba S9

The Roborock S6 and iRobot Roomba S9 are somewhat evenly-matched, but for different reasons. The Roborock is slightly easier to maintain, incurs marginally lower recurring costs, has a longer overall battery life, and is more effective with clearing large debris, like cereal, on bare floors. It also has a mop attachment to deal with wet messes, but we don't test that particular feature. Conversely, the iRobot performs better on carpeted surfaces, has a slightly larger dirt compartment, and charges almost twice as fast.

Neato Botvac D7

The Neato Botvac D7 and the Roborock S6 are similarly performing vacuums with different qualities. The Neato is better at capturing all debris on low and high pile carpet, and while its battery doesn't last as long as the Roborock, it has a shorter charge time, and it has removable batteries, which is nice. It's also easier to maintain, but it has slightly more recurring costs. The Roborock, on the other hand, is better for bare floors and it even has a mopping feature to help clean wet messes, but we don't currently test for this.

iRobot Roomba 960

The Roborock S6 is better than the iRobot Roomba 960 as it performs much better on any type of surface, especially bare floors. It's better-built, easier to maintain, and its battery lasts much longer, although it takes longer to charge. You can use the app as a remote control for the Roborock. However, the iRobot has a slightly bigger dirt compartment.

Roborock E4

The Roborock S6 and Roborock E4 perform very similarly overall. The E4 is slightly more compact, easier to carry, and does a little bit better on high-pile carpet. Meanwhile, the S6 features a sturdier design, a more advanced LIDAR navigation system, and superior maneuverability. The S6 features a mop attachment to clean up wet messes while a mopping kit is available for the E4, though we don't currently test the effectiveness of either feature. 

iRobot Roomba i7+

The Roborock S6 is a better robot vacuum for bare floors than the iRobot Roomba i7+. Although we don't currently test for it, the Roborock comes with a mop feature that attaches to its underside, allowing you to clean sticky messes. It has a higher build quality, is easier to maintain, and has fewer recurring costs. It has better battery performance and it does a significantly better job on bare floors. However, the iRobot cleans carpet more thoroughly as it can pick up more small and large debris. It also comes with an automatic dirt disposal feature in its charging dock, where the robot returns to the dock and empties its dirt compartment into a larger dirtbag for easier disposal.

Dyson V11 Animal

The Dyson V11 Animal and the Roborock S6 are two very differently designed vacuums. The Dyson is a stick/handheld with little recurring costs and easier maintenance. It has a slightly larger dirt compartment, and it can be reconfigured into a handheld vacuum for cleaning tough-to-reach places. It also does a better job of cleaning low and high-pile carpet. However, the Roborock is a robot vacuum, which is better if you prefer a hands-off approach to cleaning. It's more maneuverable, it does a better job of cleaning bare floors, and it's well-built. It also has a longer-lasting battery life, and it comes with a mop attachment feature for tackling sticky messes, although we don't currently test for this.

iRobot Roomba E5

The Roborock S6 is a much better robot vacuum overall than the iRobot Roomba E5. It has a better build quality, less recurring costs, and its dirt compartment is larger. Its battery lasts longer on a single charge, and you can adjust its surface type strength either automatically or manually, which is nice. It also does a better job overall and all surface types cleaning small and large debris as well as pet hair, and it can maneuver much better too. There's even a mop feature for cleaning wet spills, although we don't test for it, and there are even more automation features available using its companion app.
