After only 5 or 6 cleanings, all the rubber lips of the cleaning brush are torn in the centre. Hair is now getting caught in them. In the cleaning history, the Xiaomi Home app shows me a total area cleaned of 166 square metres and a total cleaning time of 199 minutes. The remaining service life of the main brush is displayed as 295 hours. We are a pet-free household. Should I assume that I will need a replacement brush every few days or can I assume a product fault and get the brush replaced? In the first case, I would appreciate recommendations of alternative devices and return the product.
