These straps are perfect for the Dyson DC 33 - installation is a headache and you need to follow the installation video very closely. I thought I made a mistake and ordered the wrong straps as they do NOT list DC33 but they fit. I couldn't believe how much my old straps stretched compared to these new straps. Finally put everything together AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA no brush! So I searched "DC 33 without brushroll" to find videos describing how to remove the 2 plastic brushroll plugs where the massive, crimped clumps of hair and fur always clog and take over the brushroll. It was terrible on both sides. I cleaned everything, reassembled and SUCCESS! Brush roller strong!
