- typical sawdust extraction from power tools - sucking up sand, cement dust and lumps from between bricks - quiet enough to be used in a confined space - blow facility, preferably via a separate port
On getting stuff from between bricks, I am repointing a wall and the old lime mortar is very crumbly. Any time I scrape away the existing cement dust more dust and lumps are pulled down. A vacuum should hopefully clear the cement and sand away and leave it clean. A domestic vacuum fails to clean out the spaces, which is why I am looking for something more powerful.
On the blow port, I've seen what looked like a good workshop vac with a blow facility but it basically blew the air back the way it had come. I think I would rather the air kept going in one direction.
We had a domestic vac years ago where, in order to get it to blow, the hose had to be attached to a different point on the housing. That seemed more sensible to me as it was easy to change and avoided spitting any dirt back out again (being after the bag and filter) but perhaps I am old fashioned!
I've never had a workshop vac before. I guess it would be convenient if there was a way to have it stop and start automatically when the power tool it was being used with stops and starts. But I don't know if such a facility exists. Failing that, some way to start it remotely might help, in case the machine is a long hose away from the tool being used.
Is there anything else I should look out for in a first workshop vac?
