Dyson DC17 Cyclone Cleaning

Introduction

This is a brief guide on how to remove the DC17's canister and clean its cyclone assembly. If a DC17 filter is loading with more fines and hair debris than usual or struggling to make vacuum as noted by the noise the DC17's motor emits, it may be because a portion of the cyclone's internal assembly is blocked. If portions of the cyclone assembly are blocked, the remaining open portions will encourage air to pass at a higher velocity, which keeps debris suspended until it hits the filter further downstream. Following these steps will clean the cyclone's internal channels and allow debris to once again fall out inside the canister.
