For anyone who needs a stubborn dirt brush to fit Dyson Ball Animal Origin with telescopic hose that has a diameter of approx 45mm, you need 2 accessories. You need stubborn dirt brush Part no. 918508-01 and quick release adapter tool Part no. 967370-01… be very careful as to what Dyson recommend…. It’s taken me MONTHS and 3 different delivered stubborn dirt brushes that are too small (40mm dia) alot of online conversations to finally get the part I needed. If you do get stuck, I found email the best way of contact: owner.support@support.dyson.co.uk and they answer quite quickly.
Hope this helps others
