Braava m6 Design

The design of the Braava m6 robot mop is basically a more advanced version of the Braava 380t.

What does it look like?

The Braava m6 has an all white body with silver and gray accents. with simple on-board controls or more advanced controls available when using the controls available on your smartphone.

How does it work?

The Braava m6 cleans using a physical mopping pad or a spray jet that wets the floor directly in front of the mop.

1. Imprint Mapping

The Braava m6 uses Imprint Technology to effectively navigate the area and determine where cleaning needs to happen. When paired with the app, you can assign different names to zoned spaces for a more accurate display of cleaning.

iRobot Roomba app smart mapping

Zoned cleaning even allows for the Braava m6 to be paired with a voice-control device, like Amazon Alexa or Google Assistant.

This makes it easy to activate the m6 with simple commands, like… “Braava, clean the kitchen.”

2. Imprint Link

Imprint Link is a secondary part of the Imprint Technology that allows the Braava m6 to communicate with the Roomba i7, i7+, S9, or S9+ robot vacuum.

Using the combination of these smart robot vacuums and the m6 mop, these two different styled devices work in tandem to vacuum, dry sweep, and wet mop all of the floors in your space.

When the vacuuming is done, the i7 or S9 will communicate back to the Braava m6 and let it know that it’s time to clean.

3. The Mopping Pads

The Braava m6 comes with a series of mopping pads designed for different messes:

  • Wet mopping pads
  • Dry mopping pads

Depending on the pad that is installed, the Braava jet will automatically adjust its cleaning mode to fit the appropriate pad.

4. Recharge and Resume

The Braava m6 doesn’t list a difinitive run time, as it can vary based on what cleaning pad you have installed. That being said, it does have the ability to Recharge & Resume.

The technology allows the mop to clean until the battery is low, return to the charger to juice up, and then continue cleaning after a charging cycle. It will automatically return to the last place it mopped.

This effectively allows the m6 to run for as long (or as little) as it needs in order to finish cleaning your home.

Accessories & Parts

Included with the mop itself are a few basic accessories.

The Braava jet m6 comes with:

  • Braava m6 mopping robot
  • Dry sweeping pads (qty: 2)
  • Wet mopping pads (qty: 2)
  • Mopping cleaning liquid
  • Charging base
  • Power cord

  • Mopping Pads – The Braava m6 comes with 2 designated cleaning pads, one type for dry sweeping and one type for wet mopping. Once the pad is installed, the mop will automatically adjust cleaning cycles based on which pad is installed.
  • Cleaning liquid – While you can technically use whatever liquid cleaning agent you prefer (or water), iRobot does equip the m6 with a small bottle of cleaning agent to get you started. Here’s a homemade hardwood floor cleaner recipe.
  • Charging Base – This mopping robot will automatically return to the charging station when any given cleaning cycle is complete. It may also return in the middle of a cleaning cycle if the battery gets too low to continue cleaning. In this case, the m6 may charge up and then return to the last spot it cleaned once the battery has been sufficiently charged (Recharge & Resume).

Cleaning Tests

The majority of products reviewed by the Modern Castle team go through a series of in-house tests to really see how these perform.

Since the m6 is so new we haven’t had a chance to complete our in-home tests yet.

In-home testing of the Braava 280t (on left) and Braava Jet 240 (on right)

That being said, based on what we learned during our cleaning tests of the Braava 380t and the Braava Jet 240, there are a few assumptions we can make about how well this model likely performs.

Braava 380t

  • Mud: 100%
  • Honey: 100%
  • Soda: 90%
  • Sweeping: 100%

Braava Jet 240

  • Mud: 95%
  • Honey: 85%
  • Soda: 70%
  • Sweeping: 93%

As you can see, the Braava 380 was a pretty big jump in performance, compared to the Braava Jet 240. This is partially due to improved sensors and partially due to improved equipment.

The Braava m6 takes even bigger leaps in advancements over the 380t, which would likely yield even better results.

One note is on the soda test. In the case of the Braava 380t, the inability of the mop to capture all soda dropped was less of a sensor issue and more of a mop pad capacity issue.

When we tested these robot mops in-house, we poured our 3 oz of soda on the floor, which as it turns out is just a lot of soda for this style of mop to soak up.

NOTE: If you foresee yourself making larger liquid messes like this, you may want to consider a mop better equipped to handle liquids, like the Bissell Crosswave stick mop.

Setup & Usability

Like its Braava mopping predecessors, the Braava m6 is incredibly easy to set up and use.

There are cleaning buttons directly on the mop itself or you can access advanced features via smartphone app.

From the mop, you can:

  • Start a cleaning cycle.
  • Send back to the charger.
  • Spot clean a small area.

Using the app, you can:

  • View the cleaning performance.
  • See a digital map of your space.
  • Establish zones.

How to use the Braava m6?

Once you know how the controls work, getting started is as easy as:

  1. Insert a cleaning pad.
  2. Fill up the water reservoir (if needed).
  3. Press clean (on the mop or the app)

Maintaining the Braava m6

Keeping the Braava m6 in working order is also pretty easy (as you might have imagined).

The cleaning pads are all machine washable so its easy to cycle through those since each package comes with two of each type of pad.

Maintaining the Braava m6 mopping robot
Remember to fill up the reservoir.

As for the water reservoir, just make sure that it is full before starting a cleaning cycle. If the Braava detects that it has run out of water during a wet mopping cycle, it may return back to the charging dock prematurely.

Is the Braava m6 a good value?

The overall value of the Braava m6 basically boils down to features. If you’re looking for a less expensive robot mop, the Braava 280t and the Braava Jet 240 certainly provide less expensive alternatives.

But if the advanced features of the m6 have caught your eye, it might make sense to bite the bullet and go for the m6.

Here’s exactly what you’re getting as “new features” on the Braava m6:

  • Jet Sprayer – provides a direct stream of mopping liquid (only available on the Braava m6 or Braava Jet 240 – not available on the Braava 380t)
  • Imprint Mapping & Zoned Cleaning – makes it easier to navigate larger spaces or complicated layouts (only available on the Braava m6)
  • Imprint Link – allows the m6 to pair up with the i7 or S9 robot vacuum series (only available on the Braava m6)
  • Recharge & Resume – sends the m6 back to the charger when the battery gets low in the middle of a cleaning, allowing it to juice up and then get back to cleaning when the battery is sufficient (only available on the Braava m6)
  • Wifi-Connectivity – makes it easy to partner the m6 with your smartphone for more advanced controls (only available on the Braava m6)

Who Should Buy the Braava m6?

Wondering if the Braava m6 mopping vacuum is right for you?

Overall, the m6 is an excellent robot mop and really excels at navigating large floor plans, integrating with smart technology, and cleaning performance.

Based on what we know of the m6 and the performance we can assume, I would recommend the Braava m6 if you’re looking for the following features in a robot mop:

  • Want excellent navigation: The advanced sensors as well as Imprint Technology makes it easier for the m6 to navigate around large or complex spaces. Zoned cleaning puts more power in your hand and takes the guesswork out of what and where your m6 is cleaning.
  • Want wifi-connectivity: The Braava m6 is currently the only exclusive robot mop by iRobot that comes with wifi connectivity. This makes it easy to control it from your smartphone or even voice control (when paired with Amazon Alexa or Google Assistant device).
  • Want a partner for the i7 or S9: If you’re looking for the perfect partner for your robot mop, the m6 could be “the one” as it easily communicates directly with the Roomba i7 or S9 robot vacuums for a truly collaborative home cleaning experience.

  1. Do you know how much liquid or moisture is left behind on the ground once the m4 passes over the jet spray?

    I want to know if this will harm my hardwood floors by leaving excess liquid on the floor after it mopped it.

    • According to iRobot it’s able to clean hard floors including hardwood, tile, and stone.

      It’s hard to quantify the exact amount of liquid left behind. But in our experience with other Braava mops, they typically air dry within a couple of minutes or less.

      I have wood floors in my home and I’ve never felt they were in danger of damage.

  2. Derek thanks for that.
    I have never used them before, I have in the past had other handheld moppers like the Hoover etc. They left a lot of water behind and everything.
    My hardwood floor installed was not a fan of them because of that and the amount of heat possibly which could damage the floors over time.
    I asked him about the new m6 robot mop and he was not sure. He said it depends on how much liquid it left behind on if he would trust it. But he did say if it was about the same as if you using the swifter like mopping pad I currently manually use it would be fine.
    Do you think they leave about as much liquid behind as if you used a spray bottle and swifter mop to mop the floors or do you think it would leave more behind?

    Also the i7+ can link to the m6? I thought that feature was only with the s9+, that would be cool since I have the i7+ as well and would be neat if it could link to it and know when to mop after the i7+ was done vacuuming.

    • I cannot imagine the m6 would leave any more liquid than a swiffer. I really don’t think you’d have any trouble with it.

      All other Braava mops I’ve tested end up being quite light on water (I usually double wet the pad itself to give it a little more water in most cases).

      And confirming that yes, the i7+ can link to the m6. This is confirmed by

  3. Does anyone know if the USA version will work on UK voltage 240 volts ? Reason for asking is that it’s not available on Amazon UK. It’s available on , but 1 to 3 Months shipping. So I’m thinking to buy direct from USA, but worried about the voltage as USA use 110 Volts. Some items work on dual voltage.

  4. Thanks very much for your reply Derek. If anyone has a USA version or any other version, there should be a rating plate ( probably on the underside) which specifies the input voltage. For example, I just bought the new Roborock S6 and on the underside it’s written input Voltage 100-240, which means it can operate in the USA and in Europe and probably worldwide ?

    • Yeah, that would make sense to me.

      We are getting an M6 later in August to test. So I can check the back plate for you then.

  5. Hey,

    Was wondering if the Braava m6 has vibrating moping sweeps like the jet 240. Can you also put cleaning solutions inside the water tank?

    • Braava Jet m6 does NOT vibrate. Only the Braava Jet 240 vibrates within iRobot’s mop lineup.

      And yes, you can use a cleaning solution in the m6 (and all iRobot mops). However, iRobot does recommend their own.

      That said, I’ve used water and white vinegar solutions in both the 240 and 380t and they’ve been fine. I just wouldn’t use anything too chemically harsh.

      Even so, I believe iRobot’s warranty says you can only use water or their approved cleaning solutions. So keep that in mind

  6. Thank you for you previous reply. I have another question. Can the m6 go over door thresholds? My roomba 960 can go over them, with no issue, but my Braava 390T cannot. Was wondering if the m6 will do, cause that will influence my decision to buy the new model. Otherwise what’s the point if I still have to move it from room to room? Thank you in advance

    • I’m not 100% sure on that one.

      We’ve got an m6 arriving here within the next couple of weeks, so we’ll be able to test that specific feature.
