Vacuum producing huge spark after less than a year of use (10 minutes per week in the months of heating the fireplace !!) Referred to my expenses in Germany (22 euros outstanding), unrepaired income! After contact with the VAS Jago, the following response was given me: "Normal coals that are worn after almost a year of use!" I then asked: "Why do not you have not changed me?" "Send us the device!" Once 22 euros off at my expense, twice no! You decide the seriousness of JAGO! Anyway, finally I pick up the ashes by hand with picks dust is much greener and here is much cheaper!
