Why does my vacuum sound like it’s screaming?
Airflow Obstruction A vacuum cleaner may make a high-pitched noise if there is an airflow blockage or obstruction. The places most likely to make the whistling sound are the hose and canister. Because vacuum cleaners rely on airflow to suck dirt, any blockages will reduce suction power, thus creating a squealing noise.
How do you increase the suction of a vacuum?
One of the easiest ways to increase vacuum cleaner suction is to replace or empty the dust collection bag. As the collection bag fills, less air is able to pass through, which reduces suction power and pressure. By emptying or replacing this bag, users will enjoy a natural improvement in suction power.
Why does my vacuum cleaner shock me?
Because your hand is more positively charged than the hose, it sends its negative charges (electrons) into your hand – neutralizing the charge. You feel a shock because the skin is not a good conductor and the charge cannot disperse – thus there is an ‘explosion’ of electrons.
How do you unblock a vacuum cleaner?
Push a broomstick through the hose to force any large clogs out. Take the end of the broomstick and feed it through the hose. Push the stick in slowly so you don’t accidentally break or puncture the hose. If there is a large clog in your hose, the broomstick will force it out from the other end.

Why won’t my vacuum suck things up?
The most common cause of loss of suction is that the filters have become blocked. They may require cleaning or replacing. Another cause could be that the vacuum cleaner hose is blocked. Inspect the base of the vacuum cleaner for blockages and ensure that the belts are not broken.
