We had one of these in the shop a few days ago to look at. There will be videos and lots of photos quite soon, but for now, I can answer the questions above.
"Hopefully Sebo has figured out how to make this one quieter" - I wouldn't call it especially quiet, but it has to meet UK and EU noise regs.
"What is the filtration system set up this vacuum uses?" - The bag is the only filter I could see. But the bags are thicker than standard Sebo bags.
"Interesting you plug the cord into the vacuum to charge it. I presume the battery is internal?" - The battery is removable and not much smaller than a house brick. I've attached a photo of the battery out of the machine.
"If there’s a multi-speed option. It’ll be interesting to see if this is geared only for commercial use or if there’s a residential version also." - It's aimed at the commercial market. It's single-speed. Future models may have hoses and attachments. A corded version is rumoured to be coming to the US later on.
