My DC25 has lost a little suction and I understand that the hose has cracked over time. I found this hose and looked it up on youtube how to replace it in minutes. Make sure the port where the hose connects to the ground has no additional obstructions. I think the hose should be checked and replaced after more than 5 years of use. This saves you time and money for a new vacuum cleaner. Search youtube for dyson hose replacement, it will help you install it. If you go to the Dyson website it will cost a lot more than Amazon and you don't need an OEM for Dyson plastic parts.
