I own the 25c vacuum, it started out awesome and worked great. Now I have to reconnect it to my internet about every 2 days and most times it says connection failed. I have reset wifi, other smart devices do not have any trouble. Will be switching to a roomba if this continues. It is very disappointing seeing this unit comes at a affordable price and over all works great. But I purchased so it will clean daily when I am away, your customers support is also horrible, let us speak to a real tech.
