This post might be stupid for someone but I never do it before so I just wanna ask.

I bought a vacuum cleaner 1 month ago at Fust in Dietlikon. Didn't even open it until today. I found it lacks the small brush head to clean hard-to-reach corners. That doesn't matter much to me but the worse thing is that the normal brush head doesn't fit into the long pipe.

I want to bring it to Fust to solve that problem. Can I bring it with the receipt to any Fust store ? like Fust in Jemoli?

take it in and ask. normally people are pretty understanding and will search for one in the back or just tell you TOO BAD.
