Performance on the S6 MaxV, S6, and S5 Max were all pretty similar. They all removed about the same level of dirt and dust from floors. The big difference in these models is less about mopping performance and more about mopping coverage.

The S6 MaxV and S5 Max both have larger water tanks (as does the S7). These larger tanks allow for greater mopping coverage.

The only model we don’t have mopping results for is the Roborock S6 Pure, which has not been fully tested in our lab. That being said, it has similar specs to the S6 MaxV model so I would expect similar results.

The tank capacity of the S6 Pure is 180 mL which puts it somewhere in the middle between the S6 and S6 MaxV.

🧬 Design

So talking specifically about the design, each of these Roborocks are actually pretty similar.

Similarities include:

  • Round body
  • 2-in-1 robot vacuum and mop
  • Up-top LIDAR sensor
  • Available in black or white

Differences include:

  • Controls
  • Navigation
  • Suction power
  • Underside (brushroll)
  • Capacity (dust bin and mop tank)

#1. Controls

The controls on all of these Roborocks are simple and follow one of two different styles:

  • 2-button design
  • 3-button design

The 2-button design is included on the Roborock S5 Max and S6 Pure. Functions include:

  1. Clean: starts or pauses a cleaning cycle
  2. Home: sends the vacuum back to the charging station
controls Roborock S5 Max robot vacuum review

The 3-button design is included on the S7, S6 MaxV, and S6. Functions include:

  • Power on / off (middle button, long press)
  • Start / pause a cleaning cycle (middle button, short press)
  • Spot clean (far left button)
  • Send to charger (far right button)
Roborock S6 button controls on top
Roborock S6 button controls on top

#2. Navigation

All of the Roborock models here use the same LIDAR navigation system for mapping and navigating. They all have mapping, which allows them to create a digital floor plan of the areas it has cleaned.

The vacuums can then save this map to use with Selective Room technology, which makes for smarter, more effective scheduled cleaning cycles.

The one model exception to this good (but more basic) navigation is the Roborock S6 MaxV. This model comes with advanced obstacle detection and avoidance that simply surpasses all other models in this review. We’ve been continually impressed with the performance.

Here’s the official testing process.

  1. Place poop on the floor in desired location.
  2. Turn on the Roborock and let it get to work.

As it approached the poo, you should notice the sensors detect the obstacle and navigate around it. It can detect obstacles as small as 2″, according to the manufacturer.

So we ran this test exactly as stated and I was happy with the results. Not only did the vacuum not knock into it once, but it also mapped the obstacle on the digital cleaning report.

The is certainly a nice feature for pet owners and something you’ll only get with the S6 MaxV currently.

#3. Suction Power

There are some differences in suction power as well between these Roborocks.

Here’s the rundown:

ModelMax SuctionCleaning Score
Roborock S72500Pa97%
Roborock S6 MaxV2500Pa92%
Roborock S6 Pure2000PaNA
Roborock S62000Pa89%
Roborock S5 Max2000Pa91%

As you can see, the S7, which offers the highest degree of suction, also had the best cleaning performance. But the S6 MaxV and S5 Max were not too different, despite their differing suction levels.

#4. The Underside

The design of the underside is also similar between all of these models, with the exception being the S7 which has a few small changes.

Roborock underside comparison
S7 (top left) vs. S6 MaxV (bottom left) vs. S6 (top right) vs. S5 Max (bottom right)

Similarities include:

  • Spiral bristle brushroll
  • Spinning side brush, 5-arm (x1)
  • Navigational wheels
  • Contact sensors
  • Edge sensors
  • Mopping pad compatibility

#5. Capacity

Capacity is one area where there are minor (and sometimes major) differences between each model.

Here’s a quick rundown of how these 5 Roborocks compare:

ModelDust Bin CapacityMop Tank Capacity
Roborock S7470 mL*300 mL
Roborock S6 MaxV460 mL297 mL
Roborock S6 Pure460 mL180 mL
Roborock S6480 mL140 mL
Roborock S5 Max460 mL290 mL
* The S7 is compatible with a self-emptying dust bin that is set to launch sometime in 2021, not yet available.

All of the dust bin capacities are pretty comparable, but technically the largest is going to be the S6 at 480 mL.

For a 2-in-1 with the largest mop tank capacity, you’d likely be better off with the S7, S6 MaxV, or the S5 Max, which can all hold about 1.25 cups.

Each model in this review can save the map for future use. With a saved map, you can go into the app, label particular spaces, set up no-go areas, and more.

Size & Dimensions

Considering size alone, all of these models are basically exactly the same size.

Diameter

13.8″

Height

3.8″

Weight

7.8 lbs”

These Roborocks are a bit larger than some of the other robot vacuums we’ve tested to date, but none are massively different in terms of size or form factor.

Accessories & Parts

Parts and accessories have slight variations between each model, but the basic list boils down to the following.

What’s in the box?

  1. Dust bin: holds dry debris
  2. Mop Tank: water tank for mopping cycles
  3. Mop Pads: disposable or washable for mopping cycles
  4. HEPA filter: removes small particles during cleaning cycles
  5. Spinning side brush: spins along undersideto collect debris at edges and corners
  6. Charger + mop mat: charges the vacuum between cycles and protects floor from moisture during mopping cycles
  7. Cleaning tool: helps to clean small parts and crevices in the vacuum
  8. Water tank filters: helps clean water for mopping cycles
  9. User manual: a detailed guide of parts, insturctions, troublshooting, etc.

What’s different?

Along with the parts listed above, let’s also cover:

  1. The Brushroll
  2. The Sonic Mopping Bar

#1. The Brushroll

Between these five Roborocks, there are two main designs for the brushroll.

Rubberized Brushroll

  • Roborock S7 only

Spiral Bristle Brushroll

Roborock S6 MaxV accessories - brushroll

Included on the:

  • Roborock S6 MaxV
  • Roborock S6 Pure
  • Roborock S6
  • Roborock S5 Max

#2. The Sonic Mopping Bar

This bar is only found on the underside of the S7 model. The purpose of this bar is to provide a power scrubbing motion to the mopping pad, resulting in more effective mopping cycles and improved performance.

Roborock S7 scrubbing mopping arm
The scrubbing arm on the S7 gently scrubs up to 3,000 times per minute.

This arm can scrub the mopping pad up to 3,000 times per minute and allows you the option of adjusting mopping power in the app depending on what you need for each cycle.

👍 Usability

The setup and usability of all Roborocks are similar. Out of the box, they are essentially already put together and ready to go.

Roborock S7 size
Roborock S7 size

All you need to do is make sure all parts are installed. Check the:

  • Dust bin
  • Mop tank
  • HEPA filter
  • Spinning brush

Then place the vacuum in a central location on the charger. If you plan on doing a mopping cycle first, you may also want to place the mopping mat under the charger to protect the floors from moisture.

  • To start a vacuuming cycle, you can manually press start and the Roborock will get to work.
  • To start a mopping cycle, add water to the mopping tank, ensure the mop pad is secured to the underside of the vacuum, and manually press start.

Deep Clean Mopping

The Roborock S7 is the only model in this comparison that has the option of adjusting mop intensity. You can opt for a standard mopping cycle or a deep clean mopping cycle.

Adjusting cycle settings can be done in the app. You can also adjust scrub intensity, which is determined by the power scrub bar.

To schedule a cleaning or enable the voice control feature, follow the steps below.

  1. Install the Roborock app onto your smartphone.
  2. Pair your smartphone to the robot vacuum using the app.
  3. For voice control, you’ll need a voice device like Amazon Alexa.

Maintenance

Maintenance of a Roborock is not that different than maintenance of any other robot vacuum.

Removing the dust bin on the Roborock S6 MaxV
Removing the dust bin on the Roborock S6 MaxV

The basic list of tasks include:

  1. Clean the dust bin. Empty the dust bin as needed to ensure proper performance. The dust bin is washable for all 5 of these models as well. Just rinse with clean water and allow 24 hours to dry.
  2. Check the brushroll. Check for tangles of hair or other debris and clean as needed. You can use scissors to trim hair away from the axel or use the small cleaning tool provided to help remove other small debris. In general, the rubberized brushroll of the S7 should have less maintenance than the more traditional bristle style brushroll.
  3. Clean the sensors. Use a dry, lint free cloth to wipe down the sensors. This helps to improve navigation and obstacle avoidance.
  4. Clean the HEPA filter and replace it as needed.
  5. Wash the air filter as needed. Doing this can help extend the life of the HEPA filter.

All five of these Roborocks have a smart app that can also provide maintenance alerts as they become necessary.

Overall, none of these maintenance tasks are costly or time-consuming and there is no real advantage concerning the maintenance of one model over the other.

I would call this category a tie among most Roborocks.

The one exception…

One exception to this rule could be the self-emptying dust bin. This is a feature that is earmarked as “Coming Soon” and only the S7 is compatible with the new base.

Roborock S7 with Auto-Empty Dock
Roborock S7 with Auto-Empty Dock (launches in 2021)

If you really want a self-emptying dust bin, it may be worth it to go with the S7 and then purchase the self-emptying dust bin whenever it becomes available.

🥇 Which Roborock should you buy?

So we’ve done the full rundown of the Roborock S7 vs. S6 MaxV vs S6 Pure vs. S6 vs S5 Max. There’s a lot of models out there so how can you decide which model is best for you?

Here’s our quick summary of what Roborock we think is best.

Best Overall: Roborock S7

Roborock S7 charging dock

If you’re looking for the best overall, I’d do the Roborock S7. The S7 has some really nice improvements over the other models listed here.

Some of the top features include: best vacuum & mopping performance, mopping scrub bar, larger dust bin and mop tank capacities, and smart control. When you couple that with the option to add an auto empty base station, it’s the clear best model Roborock builds.

Best Navigation: Roborock S6 MaxV

If you have a larger floor plan or just want the best navigation, the clear winner is the Roborock S6 MaxV.

This model uses a similar LIDAR navigation system to the other models, but it also includes an advanced obstacle avoidance technology with front facing cameras that can avoid obstacles as small as 2″.

Best Value: Roborock S5 Max

Front view of the Roborock S5 Max
Front view of the Roborock S5 Max

If you’re looking for the best value, I would recommend the Roborock S5 Max. The S5 Max had good performance that was actually a little better than our tests of the S6.

It also has a larger water tank capacity like on the S7. Suction levels match that of the S6 (but at a lower price point) and it includes other smart features like app control, scheduled mopping cycles, and voice control as well.

What About the S6 and S6 Pure?

In my view, these models are both in kind of a weird position. In terms of performance, hardware, and software, they just aren’t that different than the S5 Max.

The S5 Max is less costly than the S6 and S6 Pure, while also having a larger water tank.

The only exceptions where the S6 or S6 Pure would would be a better choice than the S5 Max would be if:

  • You’re not going to use the mopping attachment
  • You find an amazing price

For most consumers, I think the S5 Max is a better choice over the S6 and S6 Pure.
