Hey there! I’m sorry to hear that you’ve run into some issues with your V11. It does sound like a likely blockage some place in the machine. If you remove your floor tool and wand, and use a smaller attachment connected right to the bin with no issue, it can narrow the issue down to something within the floor tool or wand as being the culprit. 

We do have a great video here: How to check for blockages on your V11 which you may find useful.

Hi. 

A small opening is located inside the vacuum’s canister. Look at the shroud. The door should be visible. I suspect debris is trapped in the opening, allowing the contents to drop out when the canister is in the downwards direction. 

Clearing it should solve the problem.

David. 

I think it was the filter above. The rest was clean.

I test it next time and clean the filter above with clear water and let it compleatly dry
