Vacuum cleaner makes helicopter sound when working

(1/3) > >>

david smth:
The vacuum cleaner makes a noise when you touch the back of the machine or it makes a noise and then disappears but it sounds like a blockage sound but then disappears and makes a noise like a blockage sound while vacuuming. I changed the filters and hose but it didn't fix it. Everything seems normal. It vacuums the floor but it works and sometimes makes a noise like a blockage sound. Could there be a problem with the engine? What would happen if the engine malfunctioned? Would it not work at all or would it make a blockage sound? It doesn't make a normal vacuum cleaner sound, it makes a helicopter sound

david smth:
The vacuum cleaner makes a helicopter sound when it is working. When I first turn it on, I turn it off and on again, then it is fixed. Sometimes it makes a sound by itself. I haven't found a solution yet.

david smth:
I will put a video for you to help me and the picture brand is not a very well-known brand, it is a subsidiary product of Chinese origin, there is a filter inside, there is only no bag

themadhippy:
fan blades on the motor rubbing? unless its made by harbin then its normal

david smth:
yes There are gears inside the engine that spin
and there is nothing inside, there is a burning smell, it makes a sound like a helicopter, then I turn it off and on, it fixes itself, sometimes it happens on its own
