Yeedi mop Station pro Robot Vacuum and Mop

I bought this on Nov 2022. It has one year warranty so I did not get an extended warranty. Little did I know that it would start failing after the warranty expired. For a couple of months now the mop has been stopping after a couple of minutes into is task. The error is that "the main brush is tangled", despite it being clean. I contacted customer service who, after providing useless solutions, essentially told me to reset it. I did, and less than a minute into a new task to start mapping the area, it stopped, with the same error. This vacuum/mop has not been without problems. I had the vacuum pro and because I liked it (it had a small mopping function too), I bought this one. My vacuum stopped working a few months ago. The worse thing is that I recommended it to my two cousins who bought it. They do not work anymore. For the mop, I told them to wait a year. I spent over $500, not a small amount, and it only lasted a year. So, now, I have a useless mop and vacuum. They worked for a while, but not without problems. Often times they needed help to return as they would get lost easily. I have an iRobot with a station. I have had it for over three years. I only bought the yeedi vacuum to take some of the weight of the iRobot as the Floorplan is 2500 sqf and we have a dog. I figured use the iRobot daily, and yeedi 3 times a week, only main areas, during the afternoon. I used the mop also 3 times a week. Despite all this restricted schedule, they have both failed and the iRobot keeps on going. I do not recommend yeedi. If I could get my money back, I would. If Yeedi were a respectable company, they would exchange my robots. Instead, after over $900, all they said is that warranty expired. If I could I would give it zero stars. Customer service is no help either.
