failed within a month's time. Even though it has been restarted, the program still displays the error "Brush Error" and continues to refuse to clean itself up. The error displays itself every 5–10 seconds. The merchant does not engage in conversation. The market is referring to the seller; get in touch with him. It's a never-ending cycle: this is the second week that the vacuum cleaner has been sitting there, and it still doesn't function. After seeing such a strong response from customers, I have no desire to purchase any additional machinery.
