======Make a Vacuum Cleaner====== **Materials: **{{$demo.materials_description}}\\ **Difficulty: **{{$demo.difficulty_description}}\\ **Safety: **{{$demo.safety_description}}\\ \\ **Categories:** {{$demo.categories}} \\ **Alternative titles:** DIY Vacuum Cleaner ====Summary==== {{$demo.summary}} ====Procedure==== - Cut a 700 mL plastic bottle into two parts as shown in the guide. - In the bottom section, make a side hole and several holes at the base. - Cut a cardboard disc to fit tightly inside the bottle bottom. In the center, cut a square opening to mount the gearless motor. - Cut three triangular openings in the disc for airflow. - Attach a propeller to the motor shaft, then secure the motor into the square opening of the cardboard disc. - Insert this motor-propeller setup into the bottle bottom section. - Connect the motor to a power source (such as a power bank) using a motor control element. - Cover the open end of the bottle with a piece of open-weave bandage to act as a filter net. - Reattach the top section of the bottle over the setup. - Secure the power bank to the outside of the bottle with double-sided tape. - Turn on the circuit and test by placing the bottle’s opening near small pieces of paper. The suction should collect the debris. ====Links==== How To Make Vacuum Cleaner At Home | Powerful Vacuum Cleaner For School Project - Creative Biswajit : {{youtube>lJ_3Y6wgf-A?}}\\ 📄 How to make vacuum cleaner at Home - Havi.co: [[https://www.havi.co/blogs/how-to-make-vacuum-cleaner?srsltid=AfmBOoouBPVCgfCO5Ap59sufyw_RABFuumI67So8gfTqd_PDGRhJw8_U]]\\ ====Variations==== * 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. ====Safety Precautions==== * 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. ====Questions to Consider==== * 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?
