Bought this vacuum about a month and a half ago. Fully charged it before using it for the first time and it lasted maybe a whole three minutes. I was using it to vacuum my car which was parked outside and tried giving it the benefit of the doubt thinking "maybe it overheated due to the summer heat." Needless to say that was not the case. There is nothing clogging it, I have tried washing and replacing the filter but nothing works. It makes a horrendously loud sound for the few seconds it does work. There is clearly a defect in this product as I am not the only one who has experienced these issues - or maybe the pets it was designed for were hairless cats.
