Similarities between Roborock S6 and Roborock S6 Pure

Navigation Technology

The Roborock S6 and Roborock S6 Pure deploy the same technology to move around your house. The Roborock S6 Pure comes with 11 sensors as opposed to S6's 14, but they serve the same objective and function similarly.

At the core of both Roborock S6 and S6 Pure's navigation technology are 32-bit quad-core processors. These chips enable the vacuums to maneuver with maximum efficiency. The processors also facilitate precise mapping of your home.

Resumes Cleaning After Recharge

Smart Recharge is another handy feature the Roborock S6 and S6 Pure share. Thanks to the mapping technology of these units, they can take themselves to the charging stations when the batteries run low.

Once the charging is complete, the vacuums return to the cleaning area and resume operation. You will not have to check when the vacuums get fully recharged and manually move them back to the area they were cleaning before recharging.

HEPA Filters

HEPA (High Efficiency Particulate Air) filters are highly effective filters that can extract dust particles as small as 0.3 microns. The Roborock S6 and S6 Pure have E-11 washable HEPA filters capable of removing harmful microbes and allergens from your home.

Wi-Fi Connectivity      

The Roborock S6 and S6 Pure have similar remote control features. You can access the devices through the Roborock app over Wi-Fi and operate them remotely. The app has an easy-to-use and responsive UI that lets you connect to the vacuums through the internet regardless of your location.

Similar Modes

Roborock S6 and S6 Pure offer the same types of operational modes. Here they are:

  • Quiet Mode: Consumes less battery power and emits less noise. The performance is not as strong as other modes.

  • Mopping Mode: When you activate mopping mode, the vacuums will draw water from their reservoirs and mop the floor.
  • Balanced: The balanced mode provides a balanced output without exhausting the battery.

  • Turbo: Turbo offers more intensity than the balanced mode. It leads to faster battery drainage, but the performance will be better.

  • Max: The vacuums function at their highest level on max mode. The battery runtime will be less than any other mode.

You can flip between these modes to meet the demands of various floor types and conditions. The battery life and performance are identical across almost all Roborock S6 and S6 Pure modes. A larger water tank gives the S6 Pure an edge in mopping.


The Roborock S6 and S6 Pure are identical in size and shape. So, it's difficult to tell which one is which upon first glance. There is a round knob at the top in both models, making it even harder to distinguish between them.

The easiest way to detect an S6 Pure is the absence of the spot clean button and the LED indicator. You can only see a home button and a power/clean button. In Roborock S6, you will find an indicator light, a spot-clean button, and the usual home and power/clean button.

There is a side brush in each of these vacuums designed to direct debris toward the main brush. As for cleaning sharp corners, neither of the S6 and S6 Pure can do a decent job.

This is because the vacuums are round in shape, and the brushes accelerate when they reach the edges. So, the brushes fail to collect much debris.

Scheduled Cleaning

You can schedule to clean your entire apartment or specific rooms at specific times and dates using the scheduling feature on the Roborock mobile app. You can do this in both the Roborock S6 and Roborock S6 Pure.

Mopping Mechanism

The Roborock S6 Pure comes with a larger water storage tank that allows it to mop a larger area. Other than that, its mopping functionalities are the same as Roborock S6's. Both of them have a detachable mop, and none have the option to regulate water dispersion.


You won't be getting a better battery life upgrading to Roborock S6 Pure. Roborock has used 5200mAh batteries in both the S6 and S6 Pure. You will get a maximum runtime of three hours in each of these variants.


Roborock offers its customers 2 years of warranty for the Roborock S6 and S6 Pure.

Roborock S6 vs S6 Pure: Unique Features

Carpet Sensitivity

The Roborocok S6 Pure sensors push the device to the max mode when they recognize carpet fibers underneath the unit. In Roborock S6, you have to manually switch to max mode to get the extra power you need to clean rugs and carpets.

It's a helpful feature to use when you are busy and can't pay attention to the vacuum. If the unit gets stuck on the carpet and the max mode does not get switched on, it will waste battery life.

Since the Roborock S6 Pure automatically moves to the max mode in such situations, you can expect a better result without draining out the battery. Also, the device reverts to its previous mode once it gets off the carpet to prolong battery runtime.

Faster Recharge Time

The Roborock S6 and S6 Pure both come with 5200mAh batteries, but they don't fare the same when it comes to recharging. To fully charge a Roborock S6 from zero battery, you will have to wait around 3-4 hours. The S6 Pure takes an hour longer.

Quieter Operation

When you switch to quiet mode, the Roborock S6 and S6 Pure emit 50 decibels of noise. But in other modes, the Roborock S6 makes less noise than S6 Pure. For example, the Roborock S6 Pure (69db) is 2 decibels louder than the S6 (67db) in balanced mode.

Bigger Dustbin Size

Roborock S6 features a bigger dustbin than the S6 Pure. While S6 Pure is backed up with a 460 ml dustbin, you will get 20 ml extra dust storage with the S6. Therefore, you can expect a longer, uninterrupted cleaning session with the Roborock S6.

No Go Mop Zones

Roborock has disposed of the No Go Mop Zone feature in S6 Pure, but we believe it's a valuable option to have in a robot vacuum. The No Go Mop Zone, as the name implies, allows you to draw the boundaries within which the vacuum will operate.

However, it's possible to get around this drawback in S6 Pure. You have to draw up a new map and set the boundaries to prevent the vacuum from accessing unwanted areas. That said, it's not as simple as the No Go Mop Zone feature.

Larger Water Tank

The Roborock S6 Pure packs a larger water tank. It can hold 180 ml of water. On the other hand, the S6 can contain only 140 ml. So, the S6 Pure can mop for extended periods compared to the S6.

Roborock S6 vs S6 Pure: Price Quality Ratio

Roborock S6 Pure is the newer model, and it comes with a higher price tag. However, we can't say it has enough extra functionalities to offer for its higher price. The S6 Pure can give you a bigger water tank, softer bristles, and auto-adjustment to max mode.

S6 Pure falls short of its preceding model in several aspects. It has a smaller dustbin, it doesn't come with No Go Mop Zone, it's not as discreet as the S6 in non-quiet modes, and it takes longer to charge despite having the same battery capacity.

The Roborock S6 wins the best value for money debate beyond question.

Closing Remarks

There's very little to differentiate between the Roborock S6 and S6 Pure. Both are good robot vacuums, but we feel the S6 is the best option to buy since it doesn't lack the core features present in S6 Pure. Some S6-only features make the unit more resourceful than S6 Pure.

S6 Pure has some nifty features, but we don't think those add enough utility to the unit to justify such a high price. Therefore, we won't recommend upgrading to an S6 Pure in our Roborock S6 vs S6 Pure breakdown if you already have a well-functioning S6.
