Make a Vacuum Cleaner

A simple vacuum cleaner model is built using a plastic bottle, a motor, and basic craft materials. A propeller powered by a motor creates suction that pulls in small debris, showing how air pressure and airflow work in real vacuum cleaners.

1. Cut a 700 mL plastic bottle into two parts as shown in the guide.
2. In the bottom section, make a side hole and several holes at the base.
3. Cut a cardboard disc to fit tightly inside the bottle bottom. In the center, cut a square opening to mount the gearless motor.
4. Cut three triangular openings in the disc for airflow.
5. Attach a propeller to the motor shaft, then secure the motor into the square opening of the cardboard disc.
6. Insert this motor-propeller setup into the bottle bottom section.
7. Connect the motor to a power source (such as a power bank) using a motor control element.
8. Cover the open end of the bottle with a piece of open-weave bandage to act as a filter net.
9. Reattach the top section of the bottle over the setup.
10. Secure the power bank to the outside of the bottle with double-sided tape.
11. Turn on the circuit and test by placing the bottle’s opening near small pieces of paper. The suction should collect the debris.

• Replace the bandage with different types of fabric (cloth, silk, or mesh) and compare performance.
• Try bottles of different sizes for stronger or weaker suction.
• Use different propeller designs to test efficiency.
• Add a switch to control the motor more easily.

• Use scissors and cutters carefully when cutting the bottle and cardboard.
• Ensure wires are properly insulated to prevent short circuits.
• Do not use the vacuum for liquids or fine dust.
• Supervise children during construction and use.

• What happens if you use an opaque fabric (like silk) instead of a net bandage?
• How does the propeller create suction inside the bottle?
• Why are holes needed at the base of the bottle?
• How does this model compare to a commercial vacuum cleaner in design and function?
• What improvements could make this design stronger or more efficient?
