Please never stop making these! It dry mops so well that the cloth gets very dusty from doing just one, seemingly spotless room.

This iRobot Braava Floor Mopping Robot will make my life so much easier! I had my hip rebuilt many years ago and now that I'm starting to age, house work isn't as easy as it use to be! And so innovative!
+nathan tech Depends. What kind and how much liquid spills on the floor. Because if the robot works with a pre soaked cleaning blue mop, and uses an tank with water or cleaning solution, the mop will not be dry to clean this tipe of dirt. I think this should be an iRobot Scooba's work.
As long as you use it regularly, before the floors are too dirty, it does a fantastic job. Once a week, I mop where Braava can’t fit, such as between the fridge and wall, or in tight nooks and crannies. Saves a TON of work on a daily basis!
i own seven of these units, a mix of the old EVO/Mint and Irobot. (edited to add 2021: one for each room) all tile floors, clean whole house on Saturday. yes, the washable white "dust rag" really does pick up all the crud/dust/hair. (edited to add 2021: i now prefer the swiffer heavy duty fluffy pads to get in the tile cracks ) damp dust with blue "wet rag" after, if needed. i do not use the water receptacle pad, i simply use the normal blue pad and a bottle filled with WATER ONLY, spray directly on the tile floor to keep the rag wet or damp or slightly damp. straight lines, not mopping action. i rarely use the mopping function-- usually only in the kitchen-- it's good and effective, but mopping uses a lot of battery. this is a wiper, not a vacuum. no robotic vacuum or wiper will pick up huge chunks, cat kibble, cat litter, or leaves. pre-clean utter grossness and spills. (edited to add: they keep clean floors clean) i have pets (cat barf, unexpected messes) so i inspect floors carefully before starting the machines. i also don't leave robots unattended. a warning to those with hardwood floors, can't leave a wet bot on the floor, pick it up right away. need the replace the batteries about once every two years. buy from I-robot, not ebay. the ebay batteries are junk. if the bot is losing its mind, change internal battery. also replacement rags from I robot. the ebay rags confuse the machines. too stretchy. about once a year you will find you need to take off the back panel and clean out the wheel wells. if the bot hesitates, like huh, huh, huh, huh clean out the wheel wells. bot proof your house by picking up chairs, obstacles, wires. raise up troublesome furniture on 2x4 blocks so the bot can fit underneath. if your house is cluttered, bots won't work for you. figure out trouble areas to make bots work for you.
Also helps to be good at trouble shooting and fixing things, but if you are cleaning robots are for you, I enjoy tinkering and maintaining devices much more than cleaning. They also motivate you to declutter and pick up items that get left around the house. Also some of the amazon batteries seem to have similar if not better failure rates than the robot ones at a fraction of the price, time will tell. Just don't ever leave a cleaning robot not on the charger unless you remove the battery first.
Was it really necessary to rename the same exact product you bought, the mint? It was even still selling as mint under your company, why change it and advertise a product that you didn't change in design? If the design was different, this would be more acceptable. But this is just a freaking Mint with a new name slapped on top.
@irobot I need to mention that at 1:45 he talks about the two different cleaning modes. He says wet and dry mopping modes. That is incorrect. One is the Sweeping mode for going in a straight line using dry clothes and the second mode is the Wet Mopping mode which moves back and forth.
What about commercial use in large areas in a restaurant kitchen where the floor is greasy, or industrial use in airports areas where there are tens of thousands of people traveling?
Great question! The Braava 300 series robot mop is best for residential spaces. For more information and product specifications, visit: store.irobot.com/default/braava-floor-mopping-irobot-braava-floor-mopping/B380020.html?_ga=2.36930848.1065750420.1536071268-1356913257.1492613486
380t and 390t were super popular in S. Korea and I even prefer it over even the newer jet models. PLEASE PLEASE upgrade this model to feature mapping smartphone app, i’m sure there will be a huge demand in Korea.🥲
So why does the film stop just before the robot arrives the point, where the floor changes? Because now i still dont know, if it can handle that, or will get stuck. What is the maximum hight it can overcome?
It seems it has a bug or something that it would stop working correctly after 5 years. It is still mopping and but it randomly stops for no reasons. If it mops in large area without obstacle, it seems it work better but still stops randomly but less. I checked its diagnostic tests and found nothing wrong. I have to bought a new one it just works like normal. So, it has nothing wrong with the guiding cube either. So, it seems you have to buy a new one after 5 years even it looks normal
For upkeep of hard surface floors Braava 380t does look like the best floor robot under $300, huh. If that Scooba 450 wasn't over twice as much that would be the preferable model for best sanitary cleaning, but damn, it's $600. I'm also kind of wondering why they don't utilize that Northstar cube for Roombas and Scoobas so they don't make excessive passes over the same spots in certain areas, and can thus cover more floor on a charge.
Hassle-free? We have a 380 that hasn't worked in months. It runs for maybe 10 minutes and quits. Sometimes it starts doing donuts in reverse and then quits. Can we turn our 380 in and receive some credit towards a new 380T?
Hi Augie. This isn’t the experience we’d like you to have, and we’d like to hear more about your robot’s behaviors. Please contact us at homesupport.irobot.com!
When is an update coming to this product released over 5 years ago? Perhaps with iadapt 3.0 and better coverage? I’m going to buy the new i7 vacuum and wait for an update for the mop. Any news? When will it be released? Is it even being worked on?
The new i7 roomba looks wonderful. I have the Roomba 980 and it's a breeze. But, this mopping robot really needs a home station with some kind of automatic water refill and dirty water disposale. I want to program the robot to clean the floor everyday and stop thinking about it anymore. I would spend a thousand buck for that, I would be your first client. Please, do it ! :P
How safe are these on marble floors? You can only safely use water on them, which this mopper can do, but you have to be careful to use very soft mopping materials on marble so that they don’t score it or scratch it up. Is there some particular cloth accessory that’s safe to use on marble for damp mopping?
@@irobot is there a Google home compatible mopping Robot available from iRobot ? Or are there plans to make one in the future? i really like this feature on the vacuum
unfortunately this is not possible on Braava models, because you have to set the tipe of cleaning mode and also use the gps cube. Also you have to clean the mop so you avoid spread the same dirty for all your floors. It really doesn't make sense to have schedule program on Braava models once you have to make part of each cicle.
David Arndt that’s quite a large range. Also, $160 isn’t very expensive for something like this in today’s dollars. How much does a mobile phone cost, and we all buy those every couple of years.
The Braava 380t robot mop does not steam floors. However, it has two cleaning modes. It was designed to mop and sweep hardwood, tile, and stone. Just attach a cleaning pad and press MOP or SWEEP.
Hi Serena! We think you'll be impressed with the Braava jet m6 robot mop: www.irobot.com/braava/m-series. It's compatible with the iRobot HOME App and gives you complete control from anywhere-letting you schedule, customize, and select the rooms you want cleaned.
how does it cross the transition between wood and tile in both directions? I have ILIFE V7S and it is almost cannot go across these transitions. In vacuum mode, it can but in mopping mode it has a difficult time to pass it. Every house does have these transitions between rooms and bathrooms. Anyone has an issue with Roomba mopping robot? Thanks
didn't state what happens when batteries are low on juice. or out of water in the water cartridge. They didn't also state what happens when dry and/or wet cleaning is complete.
My Braava was of use to me for only a 6 months before the battery died and the device became unusable. After you sent me a battery it died after 6 months again. And now you are refusing to help me further, sending me a link to purchase my own battery! Very cross
@@ladykemma3 Thanks for your answer kim s ! Well, actually the iRobot Braava battery is supposed to last much, much, longer than 6 month in a normal use case. As a comparison, the battery of my Roomba lasts typically 2 years, and I use it about twice as much :)
Thats not the point. Robots should be able to replace the housekeeper (i am one) but it cant. because real floor cleaning takes a lot of energy which this robot is not exerting. Real cleaning robots with be bigger. Its an expensive job to automate.

dragon4eis Can you just put all the wires on one side of the room? Then you can use the virtual wall thing to prevent the robot from coming near the wires.
My missus does the vacuuming and cleaning better than any stupid robot and all she for in return is to be allowed outside once a week to hang out the washing.! Keep your money in your pocket people.
@@ladykemma3 it can't be much better, Scooba's brush clean floors much much better than braava, preps the floor, and Scooba can also dry the floor. And it will left just clean floor, and Scooba removes more than 99% of all bacteria, Braava is just pushing all of that stuff around...
Horrible... Horrible.... Horrible experience with this product and irobot customer service. If you were not aware, this product fails miserably on carpets or rugs that have light and dark areas together. The unit is unable to deal with the contrast and your carpet will not be cleaned. You will only discover this shortcoming AFTER you purchase the item.. They won't warn you and risk losing your business. This means you need to vacuum by hand, which defeats the purpose. IRobot knows all about this and is working on a new model. Pretty sad that this is the best they could do and knowingly decided to pawn this off on customers. It also gets stuck easily under furniture meaning the job won't be done when you get home. Other than that, it works fine on other surfaces.

these floors are spotless. i want to see it clean the floor after the cat regurgitates something it caught outside.
Exactly! Me too. I’m a messy cook and I need it to pick up things I dropped too.
or if it hits a rock, and slides it along the hardwood floor scratching it.
@@trip2247 You're supposed to vaccum first, either manually or with a Roomba. Do you clean your cat vomit or rocks with a swiffer?
