Why is my cecotec CONGA 3490 Vacuum Cleaner not cleaning efficiently, or why is dust leaking from it?

This could be happening because the dust tank is full, or the high-efficiency filter is blocked, or the main brush is tangled. You should empty the dust tank and clear the high-efficiency filter if it’s blocked. Also, clear any foreign matter tangled in the main brush.
