Exactly the same model I bought at my local Target store. I was very excited by all the reviews I read and was planning to replace my Eufy which was a BF sale from Walmart. Came home and charged the device straight away, although I expected it to have some charge, but it took several hours to fully charge. I installed the app while waiting and when it came time to connect to my WiFi, the app was having trouble finding the WiFi device that was being beamed. I consider myself a tech savvy (IT pro) but this implementation was terrible considering my Eufy setup was much simpler and more accurate - not this one! After playing around with the wifi and finally getting the device to recognize my commands from the app, I was finally able to get it to start cleaning. Well, it wasn't even 30 minutes into the start of the cleaning cycle when I heard a beep and a red light on the top of the unit, I checked the app and got a drive motor error message. Pooh! checked for obstacles on the mechanical components, and nothing. still pretty clean. let it run again, not even the full 30 minutes, again! and again and again. In the end I gave up, packed it up and will be sending it back. Keep in mind that the app is sluggish and doesn't have full integration with Alexa, meaning you'll need to install skills. In any case, the device was also noisy and creaked as it moved across the parquet floor. In any case, my Eufy will remain the way it survived these ECOVACS.
