The Dyson DC25 line of vacuum cleaners combine two of Dyson's biggest advancements into one powerful machine. The DC25 uses Root Cyclone technology to maintain steady suction power while the vacuum is on, and it also uses Ball technology which lets the user move the vacuum around tight corners with ease. Most of the parts that make up the DC25 snap together using clasps, so that if a part becomes damaged or stops working, you can quickly replace that part without having to use any tools.
Turn the Dyson vacuum cleaner off and unplug it from the wall outlet before you perform any service on it.
Pull up on the yellow wand at the top of the DC25. The wand will pull out and when it is fully extended, the handle will come off of the vacuum cleaner.
Located the clip located at the base of the hose, where it connects to the bottom of the DC25. Pull back on the clip while you are pulling up on the hose to disconnect it from the unit.
Press the button at the base of the handle, just above where the hose connects to the handle, and pull back on the hose to remove it from the handle.
Insert one end of your replacement hose into the base unit, and the other into the back of the handle. Both ends will snap into place. Return the handle to its place on top of the DC25 and lower the yellow wand.
