Ventilated Shop Vacuum Attachment
Get better suction with your shop vac—here's how:
Floor attachments on new shop vacuums have little risers on the bottom edge so the attachment doesn’t get glued to the floor by suction, making serious debris pick-up next to impossible. For older attachments without risers, there’s an easy fix: Cut 1/4-in.- deep notches every inch or so along the rim with a hacksaw. Now the attachment will slide around without sticking to the floor and clean much more effectively. Thanks to Terry Thompson for this super tip.
