Bosch GAS 12-40
Hi
I have been using a Bosch GAS 12-40 for a while now, actually I have used it a lot for my house restoration. One thing I have been dissatisfied with, it's the seal of dust collecting bags, basically when the bags is new all the dirt end up inside it and the vacuum cleaning case stay clean. Once the bag start being half full the dirt start going outside of it and the case become dirt. Also the filter is suffering from this. I don't know if it's a problem related to the seal system between the bag and the motor. I have been using my bosch mainly for grinding solid concrete walls and old paint applied on top of it, that generate very fine dust maybe finer than wood chips for example.
I'm wondering if this is a common problem even with professional vacuum cleaner life festool or if it's downside of the Bosch GAS 12-40.
Thanks.
