This is advertised as an attachment for a shop vacuum which typically has hoses much wider than a conventional vacuum. The holes/necks are usually much wider, so the nozzles also need to be wider to fit the Shop Vac. Realizing how small they were and that we couldn't use them on our Shop Vac we tried to see if we could use them on our regular vacuum but they were too small for that. In my opinion this is false advertising. I am very disappointed and am sending it back.
