What can you take as the basis for a homemade unit?
Many people are interested in how to make a vacuum cleaner with their own hands.
You can take as a basis:
- Hood motor with centrifugal fan. The axial model is not suitable, since it is used in models in the cheap segment and does not have the required power.
- The engine of a disused vacuum cleaner.
- Washing machine motor.
- Refrigeration compressor motor.
Refrigerator Engine Application
How to make a vacuum cleaner from a refrigeration compressor? It will be difficult to select a part, since the shaft rotation speed varies among different models of refrigerators. If you are assembling a vacuum cleaner, then a strict 6000 rpm will be required. Old rocker type compressors are designed for 3000 rpm.
Crank modifications have half the speed, and linear inverter units are not at all suitable for assembly.
There is an electric motor inside a piston compressor. If you cut the housing and remove the motor, it will be suitable for any purpose. It has high power and silent operation.
Asynchronous motors are rarely used. For example, a manifold configuration operates from a wall outlet if speed control is not required.
Design features of a construction vacuum cleaner
Equipment intended for construction or repair must be productive and reliable. Such devices are used more intensively and under more severe conditions than devices for the home. The debris left behind after repairs may contain small stones, chips and metal shavings. Construction dust particles are also, on average, heavier and larger than household dust particles.
Design features of construction vacuum cleaners:
- high suction power (from 1.0 to 7.0 kW);
- large dust container (30–60 l);
- additional protection of engines from dust in the form of membrane filter covers.
On a note! Construction vacuum cleaners are designed for long and continuous operation, therefore they are often equipped with motor cooling systems.
Professional vacuum cleaners are used not only for cleaning construction sites, but can also be attached to other equipment using special holders. Suctioning up dust during operation helps protect people's respiratory system and makes future cleaning easier.
Construction vacuum cleaners can be useful in different areas:
- on the street for cleaning garden paths;
- in garages and workshops;
- for cleaning cars;
- in residential areas.
A construction vacuum cleaner is a functional device that can be useful in many situations.
How to make the unit suck in dust?
In commercials they often talk about the vacuum created in the vacuum cleaner. The engine supposedly contributes to the vacuum, into which the drawn air flow rushes. But is this really so? Most likely not, because with negative pressure a bypass valve is connected to ensure equilibrium. But this is not the essence of the work. To suck in dust, a hermetically sealed housing is used, thanks to which the flow of nitrogen and oxygen molecules rushes in the desired direction. The container does not play any role in this case.
If you stick to the factory configuration, you need a bucket made of steel or plastic, the bottom of which has a hole for air intake. The motor is mounted on the axle, and something similar to a squirrel cage is installed on the shaft. The air flow is captured by the blades and thrown out to the perimeter. This ensures traction. A hose is sealed to the bottom. We will assume that assembling the vacuum cleaner with your own hands is completed.

The upper part of the filter housing is also dry, I have already glued the motor mounting studs and the adapter centering ring there.
I tried on the air filter, it fit inside like a native one.
One of the biker brothers gave me the hose, I didn’t have to buy it
Next, I secured the lower part in the barrel and installed the hose
I cut out a rubber gasket and screwed it on. I also cut out another gasket for the engine.
The top casing is a plastic bucket from Auchan, costs about 300 rubles (expensive, stsuukko
