Xiaomi Roborock T6 robot vacuum cleaner review: one of the most powerful smart robots on the market

By  GB Blog Official 2019-03-26 13055 0

Last week was big on new gadget releases — and the smart home appliances category was not an exception. A few days back, Xiaomi released their new flagship robot vacuum — the Roborock T6. The Roborock T6 vacuum cleaner is a complete upgrade products of its predecessor Roborock S5. The new T6 smart vacuum cleaner comes with better sensors, improved navigation, advanced noise reduction, upgraded wet mopping mode and new app-related functionality. With Roborock’s previous robotic vacuum models being very popular, we are eager to see what the new Roborock T6 has in store.

Xiaomi Roborock S6 robot vacuum cleaner: award-winning design

The Roborock S6 comes in the industry-standard circular shape and measures 13.8 x 13.7 x 3.8 inches and weighs about 3.6kg. Under the hood, there is 500 ml dustbin.

The body of the robot is made in simple matte black, which is a good choice compared to the glossy finish on some of the previous models as a matte finish leaves fewer chances for the annoying fingerprint smudges.

Another improvement is the new charging dock that lets you hide the vacuum cord and release it as needed. This is a very nice upgrade as tripping over cords in your house as you are cleaning it up is hardly pleasant.

For all the improvements and its overall good looks, the company has already received the iF Design Award.

Xiaomi Roborock S6 robot vacuum cleaner: how it works

The Roborock S6 is comes with a side sweeper, a main cleaning brush and a powerful motor. Together, these components let the S6 pick up dust and debris and store them inside. The vacuum features 14 different sensors, which allow it to efficiently navigate through a home, avoid furniture, move around corners, etc. The S6 can also independently return to the charging dock when it's done cleaning or when its battery is low.

Xiaomi Roborock S6 robot vacuum cleaner: battery and charging

The new S6 features a rather large 5,200 mAh Li-Ion battery — in usage terms, this translates into up to 150 minutes of cleaning time. This should be enough to spotlessly clean a standard-sized apartment without recharges or to spot-clean a relatively large home.

If the remaining charge on the vacuum cleaner gets below 20%, the Roborock S6 will head to the charging dock to recharge. Once the vacuum has recharged to 80%, it will pick up its cleaning routine where it left off. If the robot vacuum does not need a recharge during the cleaning process, it will return to the charging dock once its cleaning route has been completed.

Xiaomi Roborock S6 robot vacuum cleaner: improved navigation

The Roborock S6 is equipped with an LDS laser hidden inside a small tower atop the vacuum cleaner. Thanks to the laser as well as the implementation of the New Map Management 3.0, the vacuum now sports a better mapping algorithm. This, in turn, leads to faster, smoother and more accurate navigation.

the New Map Management 3.0 

The robotic vacuum runs on three processors that allow for real-time tracking and you will be able to track the robot's movements in the Mi Home app.

Before the robot starts the cleaning process itself, it creates a map of the area and calculates the most efficient way of cleaning. It will then start moving along its route in straight lines, back and forth. Another advantage of the vacuum's advanced mapping system is that you get to save plenty of time: the Roborock S6 will not clean the same along the same route twice.

The robot vacuum is also capable of storing maps, which makes it a good option for homes with complex designs or several levels as it will remember all the angles, corners, pathways and staircases and will not fall or bump into furniture or walls.

Xiaomi Roborock S6 robot vacuum cleaner: app control via the Mi Home App

There are several convenient control options for the Roborock S6 available via the Mi Home App. For instance, the new mapping technology allows the vacuum to recognize different rooms. This means that you can assign the S6 to clean a specific room — like your kitchen — and even set a specific time for the robot to clean it.

the Mi Home App 

The app also lets you switch between several cleaning modes, manually navigate the robot vacuum (like a radio car), track the S6 in real-time, turn it on and off, etc.

In addition to app control, the S6 can be managed through voice control. At this point, this functionality is limited to the Xiaomi Mi AI Speaker. We are not yet sure if the S6 will support Alexa or Google Home.

Xiaomi Roborock S6 robot vacuum cleaner: Smart detection

The new Roborock S6 crosses carpets, door thresholds or other edges that are up to 2 cm high without any problems. The device also automatically detects when it is on a carpet and then increases its suction power automatically.

Activate the wiping function of Roborock's latest robot and it will simultaneously vacuum and wipe without leaving streaks or other residue. You can adjust the amount of water to suit your floor. The Roborock S6 cleans according to your wishes.

Xiaomi Roborock S6 robot vacuum cleaner: powerful but quiet

The Roborock S6 comes with a strong motor capable of delivering up to 2,000 Pa of suction, which makes it one of the most powerful robotic vacuums on the market.

The vacuum is also equipped for cleaning carpets. Typically cleaning a carpeted surface requires more suction power compared to the cleaning of hard surfaces. Thanks to the build-in sensors, the Roborock S6 can recognize a carpeted area and adjust its suction intensity accordingly. Paired with the robots good climbing ability, this makes it suitable for cleaning carpets that are up to 20 mm thick.

Despite featuring a powerful motor, the S6 promises to be quiet thanks to the improved sound insulation and a noise reduction air screen located next to the motor. According to the manufacturer, this results in a 50% noise reduction compared to the previous models.

Xiaomi Roborock S6 robot vacuum cleaner: new components

Another improvement on the Roborock S6 is the new brush made with DuPont Zytel material and featuring easily detachable parts for better cleaning. The S6 also comes with a 500ml water tank. The vacuum is sold with ten disposable wipes: you can easily remove a disposable wipe after a cleaning session.

Xiaomi Roborock S6 robot vacuum cleaner: the verdict

The Roborock S6 is now available for purchase for around $420. This is not cheap for a home appliance, even a smart one. But, the S6 does comes with a strong selection of features and, as we've mentioned above, is one of the most powerful smart vacuums on the market. Let's sum up what you are getting with the Roborock S6 :

● 2,000 Pa high suction power, cleaning carpets deeply

● 5,200 mAh Li-Ion battery, long battery life

● 14 onboard sensors

● App and voice control

● Digital boundaries and zone cleanup

● Carpet boost cleaning mode

● Auto charging dock return

● Automatic mapping

● New removable DuPont brush

●​ Vacuum cord storage

●​ Low noise level (quiet 58db)

●​ Easy handling and maintenance

Are the improvements on the new S6 enough to upgrade if you already have the Roborock S5? We are not quite sure. While there are several notable improvements on the S6, there could be more: like a self-cleaning docking base, rotating mop, etc.

With that, if you are looking for a new robot vacuum cleaner, the Roborock S6 is a very strong contender for the best option.
