I used to place my vacuum cleaner’s nozzle next to a hole being drilled to suck up any brick dust and prevent it from falling down. This was not ideal though because the motor filter is not suited to very fine dust. Now, I would like to share with you a great new tip, a much better way to pick up brick dust that cannot damage the vacuum cleaner.
Use a dust pan (because it has a wide brim and a nice handle!), place a wet kitchen towel over it and locate the dust pan right under the hole being drilled. The falling brick dust will be collected by the wet kitchen towel. When finished, simply put the kitchen towel in the bin. Try this tip and let me know what you think!
