Bad product, manipulated reviews.
Bought a Tesvor x500 vacuum robot on Amazon because of the great reviews. The robot really disappointed, mopping carpets, completely losing its progress if interrupted, and not being able to navigate carpets. Because of the above, I gave them a bad review on Amazon. Against Amazon’s rules, they e-mailed me, including saying they would give me a full refund and could keep the robot if I deleted my review. I reported them to Amazon, who issued me a refund. I still feel cheated, as I would not have bought the robot if not for the fantastic reviews, which I now know are manipulated. Stay away. Dec 2022 update: an app update added an unskipable ad and made it impossible to connect to the robot, making the app useless.
