Cordless is the future without doubt, I've even been buying cordless stuff for workshop use lately.
The cordless extractor is great, I have a bluetooth version, that's dedicated to a plunge saw. It doesn't have the power of a CT etc but, works great, at least with the plunge saw.
I think Makita missed an opportunity though, where as Festool has bluetooth built into batteries, which makes perfect sense. Makita, actually have there's in the PCB where a module plugs in. So Makita are currently doing a line of some tools without bluetooth, and an identical line with bluetooth.
That is a very odd way of doing things I think. If you've just bought a few tools from them and an extractor, and realise there is a bluetooth version of everything available, you'd be a bit upset.
The bluetooth tools are obviously more expensive, sure a better way is to follow Festool's lead, or make all the cordless stuff that has dust ports, bluetooth?
