the app is generally fine and i enjoy most of the features. unfortunately it does not send notifications. no matter how hard i try i can't get it to notify me when the robot is stuck or a similar event has happened. please add a notifications setting. it is not even registered to use android's notification system. the allow notifications toggle is grayed out and can't be turned on samsung s24 ultra android 16

There is a problem with 3-series robot vacuums. We've tried two of them so far and they continually show up as "offline" when we launch the app, even though both 3-series vacuums appear to be successfully docking after each use. Except that, when you turn the power on, it's evident that they are NOT charging, so we have to wait for them to finish charging before starting another job. And both units have strong WiFi connections. Our 5-series vacuum has none of these issues and is always online.

The app is ok, nothing groundbreaking. The most advanced feature seems to be the ability to track where the robot is on the map. My RCV3 does not connect to the charge station once is goes "home" and always misses by 2cm in a neverending loop. Very frustrating. Kärcher support is very poor.

The app used to work properly until some time ago, but recently I've had some problems with the app. When I open the app the message "Network anomalies. Please switch network." apears and nothing works on it, maps, controls, nothing.

I haven't had any major problems with the app until a few days ago when it decided to delete the saved map and at times refused to log me on due to "network anomalies". As the robot vacuum doesn't work well or allow you to see where it is without the app, this has turned a supposedly intelligent robot vacuum into one with the capabilities of the cheapest ones on the market. Very poor effort by Karcher.

Worked fine for a while with both an RCV 3 and RCV 5, then all of a sudden my maps disappeared. And I can't get them back, even when deleting and creating new maps. I tried deleting and reinstalling the app, resetting both machines to factory settings and reinstalling on my home network. Still no maps. I sent both units out to clean and they are apparently following some kind of map, but I can't see the maps anymore... but I used to. Major software bug!!!

owning RCV2. No maps visible and you don't know where your robot is stuck. Home map is a must and should be reliable

The app is switching between two views, sometimes I see the map management and sometimes it's not there. So my robot is never saving the map and I cannot manage it. may I please ask you to fix it?!

worst smart devices app ever, there is so many bugs. The app is poorly built in general, and the connection from the cleaning robot to the app works 1/10 times.Also there is "features" that are promised in the app that dont accually work.

I find it VERY frustrating that I have to deal with "session expired" from time to time. It's an unnecessary security measure for an app of this purpose. I myself, while I find it annoying, don't mind typing my password every now and then. But I'm setting the robot vacuum cleaner for my mother who is not very tech savvy and sees something like having to type a password as a nightmare. Please consider removing it or adding the option to be kept logged in. Thank you.

Robot performance is great. App is terrible. The cleaning ability of the actual robot is fantastic and I have no issues with it at all. The app, however, is terrible. Initially had problems trying to connect the app to the robot but once that was done, the issues started. The map rarely loads up and I have to go out and come back in multiple times before it loads. The list of schedules is blank until, again, I go out and come back in multiple times. Same for the cleaning records. Could be great

the app is not very intuitive, defining restricted area is difficult, and there are errors when selecting only mopping, sometimes, mop usage is marked incorrectly, and the app is very slow. The robot occasionally temporarily loses the map, and sometimes it also forgets where the charging station is. The robot has also had issues with using the mop.

App offers many functionalities and works. The UX needs improvement. There is no need to separate viewing and editing maps. Also, I have to adjust the map every months, because it is changed or recreated automatically for some reason. I would expect my changes to be permanent and the map immutable.

Robot is still working. Software is a total mess. 1. Robot appears Online in the robot list, then when entering the map it says "Connecting", even though the robot is connected in the docking station. 2. Map dissapears from time to time, so you have to recreate it. When this happens you can only use the robot in manual mode. Error: "Please let the robot complete a full clean to create a map" 3. The "AI object recognotion" doesn't work anymore. Worked fine for 1 year. Last service: oct 2024

doesn't work without internet, even though locally everything has been configured. local devices talking to each other is a concept unknown to this app. it's a shame, the moment anything goes down (be it my internet or their servers) any of the robots lose most of their functionality. i won't be buying any more karcher ones until that's resolved. otherwise it's a good platform, some settings fail to update (voice language) tho. the mapping is pretty awesome, bummer the no-go zones are so big.

The app still needs improvement; it negatively affects the impression of the vacuum cleaner. I've had the vacuum cleaner for a few days, and I've already encountered these issues: 1. The app displays outdated data. 2. After changing the Wi-Fi password, I had to perform a factory reset. So far, the app doesn’t seem as bad as I’ve read in other reviews. At the moment, I wouldn’t buy another Kärcher product that relies on an app. I’ll be happy to update my review once the app improves.

The app ir absolutely horribble. Hello, is this really german quality we are talking about? You have to fix this asap, because it ruins Karcher reputation. Map is not working and is not displayed 99% of the time. You can't add robot to multiple devices. UI ir unusuable. I hate my device because of this app. Please fix it for your own good.

I guess it's new and needs some polish but basic functions work well. Niggles seen so far: * If, when mapping, the robot misses a corner, it never mops there. It needs to iron out the errors in the initial mapping, not treat the map as perfect. Maybe one could merge in grey areas in the map for starters? * The mop is quieter than a Roomba but louder than our other robomops and the sound has an intrusive high pitch. * The app takes a couple of seconds for every change to take effect.

Just purchased RCV3 it does full cleaning but the map is not saving all the time so you have to start from zero, is this acceptable? Please fix this app it's really horrible all the reviews are accurate here P.S. Yes I can see the map now in real time, you guys fixed it. It works smooth now, thanks!!!! I'm giving 5 starts because you are reading customer reviews and fixing the issues

Update: my model is the RCV5. I've encountered a bug where the robot miscalculates it's height, causing to hit furniture. The issue occurs where the body of the robot is low enough to fit under furniture, but the sensor on top is too high. The robot seems to calculate it's height based on the body, not the sensor that protrudes. The sensor then keeps hitting the item of furniture, risking damage. Please could the height setting be changed to reflect the total height of the roboy?

It doesn't allow to modify the app like for other robots. I have my living room and kitchen together and it is not able to differentiate and there is no option to separate it manually as well. I would like to clean more frequently than living room but it just doesn't allow. If you can make the map editable and more accurate then it will do really good work.

Everytime we open the app even without signing out it asks for password. 1)Once enter password and login, it searches for some seconds and says session expired. 2)Everytime agter log in it says connecting. 3)Need to fix bugs, need to stay connected if not logged out. 4)If logged out and when sign in it says wrong password even nothing is changed. If we go for forgot password it says email doesn't exists. I had to uninstall several times to get it work. The robot is good but app is killing

Pathetic app. The app does not connect to the Wifi network most of the time and if connected, there is a latency in the communication between the robot and the app. The login page also needs to be refined. Instead of logging in via email, replace it with mobile number and OTP login facility.

Its a great cleaning robot with a poor app. issues 1. It automatically logs off, if u want to you use robot everytime we have to log in even on the same phone 2. Sometimes the robot shows offline even if it is connected to wifi and the charging station(power is on) 3. After all above 2 issues get resolved with multiple attempts, and you wish to only select lets say living room to clean it doesn't allow with an error "please complete full cleaning first " I believe i should decide on cleaning

There is no option on the app to re-scan a single room. The RCV5 will only hoover half of a certain room but I can't find any option to make it do the whole room. Don't see any fix on the internet either.

Every now and then it logs me out. Account is not recognized and i have to register again with the exact same email address. I have to register and configure the robot again. He has to scan the place again and so on. Very time consuming! On top of that, the validation email I get to register is in Chinese and looks like a dodgy mail. Had to google it to be safe. Doesn't exactly aspire safety awareness but poor service management.
