CCArchive Posted August 16, 2014 Report Share Posted August 16, 2014 I don't know what they are called or what they are for, but on some vacuum cleaners' hoses, there is sometimes a little adjustable slot at the end of the actual hose, where you would normally hold it, that if you open lets air in through the slot, instead of just the head or whichever fitting you are using. I can only think it's a crude way of adjusting the suction. Whatever they are for, they are an annoying cunt. Quote Link to comment Share on other sites More sharing options...
