Can I ask if, from your experience, they would have sufficient ‘suck’ to take on a table saw? My Vax 6000 has a fair pull on it but not enough for a table saw but great for all my hand tools and routerI've bought 2 of each over the years. Used for £30 to £50 apiece.
The Karcher isn't made any longer so used is the only option.
The Nilfisk is alive an well.
Model GD930
Model VP930 is a pricier HEPA version of it, possibly even quieter at 42 dBA SPL, and about £350 so not at all cheap but hey, it's cheaper, much quieter and probably better built than a Festool that would set you back a lot more ...
