how to DIY vacuum cleaner?

Vacuum cleaners come in so handy when cleaning almost everything in our homes and offices. But do you really know how your vacuum cleaner works? Well, one thing that might surprise you before we even go further is that vacuum cleaners don’t work by creating a vacuum.

That’d be quite difficult to do. If you want to understand that better, you can get a syringe, put a cap on it having removed the needle, and then try to pull the plunger back. That’s how hard it’d be to try and create a vacuum to suck the dust.

A vacuum cleaner, however, uses a concept quite similar to creating a vacuum. It blows air outside to create a region of low pressure which causes high-pressure air from outside to rush into the vacuum cleaner creating what seems like a suction force. This is the main concept you want to have in mind when making a DIY vacuum cleaner.

Materials required

The main things you need when making a DIY vacuum cleaner at home include:1. Plastic bottle 2. DC motor3. Plastic handle4. Aluminum sheet 5. A power source (battery or power bank) 6. Net fabric 7. Small pipe8. Cardboard sheet9. Cutter 10. Marking pen11. Glue gun  12. Scissor

Step 1: Cutting the bottle once you have everything, get the bottle and cut it almost halfway from the base. This will make it easier for you to fit the motor, fan, and filter insider the bottle.

Step 2: Make a fan Get an aluminum sheet (You can cut one from a deodorant bottle), and place the plastic bottle you cut earlier on it. Sketch the plastic bottle’s circumference on the aluminum sheet using a marker pen. You can then cut the aluminum piece following the marking to create a round disc. Using a ruler, draw four complete vertical lines on the aluminum disc to divide it into eight equal parts that should meet at the center. Make a small hole at the center, then cut through the vertical lines using your pair of scissors. Once you have the sections, twist them in one direction in a way similar to how fans are twisted.

Step 4: Attach the fan to the motor get the cap of the plastic bottle and make a small hole at the center. Take the motor (12 DC should be perfect), and then attach the cap behind it using glue from the heat gun. The wires from the motor should go through the hole at the center of the cap. Once ready, secure the fan onto the motor’s shaft using glue. It should be ready to rotate.

Step 5:  Make exhaust holes with the help of a hot soldering iron or drill machine, make some exhaust holes at the bottom of the plastic bottle to facilitate the escape of exhaust air.

Step 6: Secure the fan onto the bottle Put some glue at the back of the plastic cap and then attach the cap to the bottom of the bottle. Get the wire of out the bottle from one of the small exhaust holes.

Step 7: Make a filter Measure the inner diameter of the plastic bottle and cut out a ring from the cardboard sheet. Stick a piece of fabric to fit the ring using some glue. You can then attach the filter onto the plastic using some double-sided tape so that it captures dust particles preventing them from being sucked out of the plastic bottle.

Step 8: Fit a suction pipe The suction pipe you attach to your vacuum cleaner should be of average length to enhance sufficient suction. The pipe should have a diameter same as that of the bottle top, and should also have a nozzle (You can make this by cutting the top of a plastic box). The difference in surface area between the nozzle and pipe helps increase suction.

Step 9: Power the vacuum Get a power bank of a battery pack you’ve made and connect it to a switch which should link the motor to the power source. You can attach the switch to the handle using glue from the hot glue gun, and then secure the handle onto the bottle using glue as well. You should also secure the battery pack onto the plastic bottle using glue for a compact vacuum cleaner. Once everything is ready, join the two parts of the bottle using duct tape or any other strong tape.

Step 10: Test the vacuum cleaner After you’re done, the vacuum cleaner should be ready to test. All you have to do is switch on the power to facilitate rotation of the fan. Once rotating, try out your vacuum cleaner to confirm that it actually can collect dirt particles. If it’s collecting dust, you’ve successfully made yourself a functional vacuum cleaner.
