I love the vacuum itself. Very effective device. However, the app is 3rd rate. Besides not being very intuitive, after a few days of use when I open the app it won't pull up the main screen that shows menu/options/floorplan. I've cleared the cache and memory and the only way to get it to work properly is to uninstall and reinstall the app. (I'm running it on Android 12 on a Pixel 5.) Just because of the app issues alone I would never again buy this vacuum or related products.
