Turn a Hair Dryer into a Vacuum Cleaner

By Mayank Sharma. Posted

Like all good makers, Chialiang Chang wanted a vacuum cleaner to keep his desk clean, but would rather create one using discarded pieces of junk, instead of buying it from a store.

He has shared the process of how he modified a hair-dryer from blowing air into sucking air. After unscrewing it, he removed all components besides the electric motor and the fan. He then reversed the motor and sawed off any part that blocked the reversed fan.

Next up, he created the dust chamber using an old container that had been discarded because its lid had some holes. He glued the lid to a piece of wood and then used a cylindrical HEPA air filter, and attached it to the inside of the lid.

Chialiang’s detailed the process in his Instructables page, which basically involves cutting the lid to fit the filter, and then drilling five holes into the piece of wood; one to attach the filter and the other four for airflow. He then drilled a larger 32 mm hole to the side of the container and passed a hose through it.

Finally, he connected the hair-dryer to the other side of the piece of wood and also wired a control switch to the contraption. Flick through his images to understand the procedure for these steps.
