I wanted this brush to complement my Dyson V8. I have a V7 to V8 converter so there were no problems. However, I find this tool a bit useless. I was sure it bends at the joints so you can change the angle in whichever direction you want, as does another very handy brush set that I also bought from Revain for my old vacuum (look for the 8th one). -part universal vacuum cleaner). Accesories). Cleaning kit for standard 1 1/4" and 1 3/8" hose - slot, upholstery brush, dusting brush tool and adapter and you will see the articulated handle I was talking about).
