What dust extractor?

I've never had a problem with screed dust. I clean the internal filter often.

 

try concrete dust from diamond grinding lol

 

Yep that would do it. :-D

 

I use a Festool unit and a couple of good old Henrys. Just wondered if anyone could recommend a Back-Pack such as this:

 

I have a nilfisk multi 20 from machine mart, good vacuum for carpets and powerful suction and takeoff for dust....only downside was I had to buy a better vacuum attachment as the one with it,was for hard floor

 

I know a few people who don't use the systianer system but use the festool midi , the 110 version and 240 have auto system for auto

 

Festool CT 26 E HEPA, the best...

 

Great vac but expensive

 

We use Numatic Charles also for the wet pick up

 

I use a Trend and bosch
