I did a lot of research before purchasing my Tineco A11 cordless vacuum cleaner. I used it daily for about 9 months and the motor stopped working. As I'd bought it on Amazon through Tineco, it was registered under warranty. I was skeptic after reading many poor reviews about the warranty but I have to say, Tineco customer support were brilliant. I rang to describe my problem and sent them videos of my vacuum. They promptly sent me a new motor and it's working like a dream again. I think customer service/warranty honouring is so important and I'm very satisfied with Tineco!
