I have a bosch vacuum since Christmas 2015 and the engine has just given up I have for more
70 . This is the first time I take the Bosch brand for a vacuum cleaner and the last one.
I have had many more and I have 4 in my house but I have never had one that ran out of engine at the end of one year. I hope to have an explanation with a gesture of your after sales service.
Sincerely, waiting to read you thanks
