[USER=594]@blackheart[/USER] My understanding is that the patents are owned by Zero-G for nozzle.
They did make that central vacuum nozzle or let someone else make it. Something of that sort .
[USER=2436]@n0oxy[/USER] The sound is my A6000 stock microphones. They suck it's a know issue with the Sony A6000 it really dose sound different in real life. I will try to use action camera for the next video it has better microphones.
Also I wouldn't buy this . Its TTI crap from the wost parts of China Town.
Just like the oreck quest.
