Another mystery of the vacuum:
These little holes that appear on some of our canister vacuums. What is it for? I should always keep it closed right? Physic says that if I open this then suction will leak out, but why would I ever want less suction?
Sometime it’s hard to connect 1 and 1. The point of these holes is so if you’re vacuuming an area rug, and the suction on your vacuum is so strong that the rug is sticking to your vacuum, then you can reduce the suction using this hole. This way you can vacuum your rug, but not vacuum up your rug. Keep in mind that you want to only let out enough suction that your rug is not being sucked up. This is important on some machines, because on some the roller is powered by the suction power.
You’ll note that you’ll never see this on an upright. This starts to branch off into Upright VS Canister, but that’s another discussion for another day. And yes, DEZMOND totally called this out before I posted it. Good job!
