Seems to me to be a very dishonest and disreputable company. My battery began to fail after about two weeks and Roborock would not acknowledge the fact. I even had screen shots showing the failures. Additionally, I had purchased the same exact model three weeks prior, the Q5 Max+ and it had the same exact problem after a similar time period. It works well when it works, however two or three weeks of function is outrageous. Thankfully, I was able to return both units to Amazon. Not sure what robot company is considered to be reputable.
