So initially we almost sent this back as the hose didn't fit our Dyson dc33 and neither did the extra connector. But my husband sanded down the ridges on one end of the hose so it would at least fit snugly in our vacuum cleaner's wand. With that out of the way we started combing our Shepherd/Husky. And clean and clean and clean! We emptied the canister twice and it was half full again. We filled a grocery bag with all the hair he combed with this amazing tool! In this unseasonably hot summer, he looks much brighter and happier. The tool itself works amazingly well. The plug just needed a good old red neck for a "fit".
