A dead vacuum cleaner brought back to life
This vacuum cleaner was brought to my shop for repair. It was a dead vacuum cleaner. When I powered it up, there was no indication of life in it.
It is an old machine and as you can see the model number and the brand name is found on this tag on the back of the machine.
I was really hesitant to repair such machine because from experience, any old one like this usually the motor is worn out.
To replace such motor, it cost the same as buying a new vacuum cleaner. My plan was to check it quickly and see what is in there.
I took the cover off and as you can see it is very dusty. I used my air blower and it looks decent.
A quick check on the main power and I was getting the 220 volts necessary for the motor to run but for some reason it was not running.
The power was reaching the main power switch but when I pushed the power switch and nothing happened.
I checked the voltage reaching the other side of the power switch and guess what, there was none.
Few screws off and I was able to take the power switch off its base and check for continuity. It turns out to be faulty. If you look at the photo, you can see the two black notches there. I was not planning to open the switch instead, I used the air blower to blow away any dust in there and then I sprayed a contact solution in there and tried the machine again. Guess what, it worked fine.
It seems like all this week I was getting repairs that were easy to fix. I am not complaining though and as always Mission accomplished.

Oh! Lucky indeed!
Nice fix ,sometimes it’s easy as a fuse and other times you have to search the depth of it.
Just a kind of repair I prefer, but not always it can be chosen….
Good job Waleed. I however guess that the owner – seeing the dusty state the 1400 Watt cleaner was in – pollutes his breathing air while using it in his home? Since there is no (clean?) air filter in it. And those inside filters probably also prevent the motor from getting dirty while sucking in air. In the EU we also use 50Hz/230VAC but not long ago the manufacturers are limited to in how much maximum power the vacuum cleaner motors are allowed to consume. This way saving unnecessary use of electricity. The thought behind this was that so much motor power was not needed to clean anyway.
