Flaw
Their latest Cinetic is very powerful in terms of sucking up dust/dirt. However, emptying it is flawed - you need to use a tool to extract hair and end up getting dust all over yourself... they provide the tool which is an admission of a design flaw.
If they can't get that right, I would not want to drive in one of their cars.
My DC01 was excellent at the time, rarely did I need to use any implement to get debris out of the cylinder.
