How to Identify and Fix Common Vacuum Problems ?

The Hoover WindTunnel Air was a bit quieter at just over 70 decibels when the brush bar was not on.
Check that the brush bar is clean and not damaged
If the cleaner becomes noisy or starts vibrating, it may be because some debris has got tangled around the brush roll or agitator situated in the bottom of the cleaner.
WindTunnel technology and Multi-Cyclonic filtration lifts and removes surface debris and deep down embedded dirt with no loss of suction. The 25ft. power cord automatically retracts in seconds so you never have to wrap a cord again. An assortment of tools and an extra-long cleaning hose offers up to 10ft.
Living room music (76 dB); radio or TV-audio, vacuum cleaner (70 dB).
Vacuum cleaners with a noise level between 71 and 75dB are loud. If you want to have a conversation with someone 2m away, you`ll have to raise your voice significantly. You also won`t be able to hear the TV without turning up the volume. We consider more than 76dB of noise very loud.
However, the noise levels of vacuum cleaners fall between 75dB to 85dB. Thus, continuous exposure to such noise levels affect a user`s health while also being a sign and source of inefficiencies in the equipment.
As the chart shows, the “strong” mode of the Dyson model was the loudest, reaching above 90 dB. The Toshiba model was the noisiest of all models in when we compared the “weak” modes, and stayed around 80 dB at “weak” mode and just below 85 dB at the “strong” mode.
A wind tunnel that is open on both ends and draws air from the room into the test section is called an open return tunnel. The tunnel at the lower right of the figure is an open return tunnel. A wind tunnel that is closed and re-circulates the air through the test section is called a closed return tunnel.
While indoor skydiving is safer than skydiving, there are minimal risks involved. Typically, risks include bumps and bruises from collisions with the walls of the wind tunnel or with other flyers.
Check the Rotator Brush and Wheels
Sometimes pieces of string or other objects get wrapped around your vacuum`s rotating brush or around the wheels of the vacuum. Unplug your vacuum. Turn it over and have a look at the wheels and brush. If you see any pieces of string or objects lodged there, remove them.
Noise at typical vacuum decibel levels, around 70 decibels, isn`t enough to damage your hearing, especially because you probably won`t be running your vacuum cleaner for longer than an hour or so at a time. Nevertheless, a loud vacuum can be annoying, particularly if someone`s trying to watch TV or take a nap nearby.
Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears. The table below shows dB levels and how noise from everyday sources can affect your hearing.
70 decibels is as loud as a washing machine or a dishwasher. It is a moderate noise level. 70 dB noise is not considered harmful to human hearing. However, extended exposure to levels above 55-60 dB can be considered disturbing or become annoying.
55 dB is a level that describes moderate to soft sounds. In fact, it is comparable to a quiet home environment, a residential street, or a normal conversation between two people. Since it is under 70 dB, it is not considered a harmful noise level.
The maximum time one can safely be exposed to 100dB is for 15 minutes only. This means it is best to choose a vacuum cleaner with a noise output that is less than 70 dB. However, the noise levels of vacuum cleaners fall between 75dB to 85dB.
The sound pressure level of working vacuum cleaners varies from 65 dB (A) to 90 dB (A).
A normal conversation: 60-70 dB. Open office noise: 65-75 dB. An alarm clock: 70-80 dB.
There seems to been a high pitched sound in the motor. I’d describe it as a ‘dry’ sound, and the high pitch of it is very loud. I want to stop vacuuming because it’s so loud. Are there any oil/greasing points/spots? If so, how do I find them?
High pitched noise is not good. It may indicate that a bearing is going out. I would not use Kirby as it may lead to burned motor.
If you feel that it vibrates quite a bit too – then it may be only broken fan blade.
Fan blade – you are looking ar around $40-$50 and if this is a motor bearing – $60-$80. If anyone wants to charge you more – we will repair it but you will have to pay shipping both ways (roughly another $30 both ways all together)
Ohhh yeah – try it with the hose. If no sound then brush roll bearings may be bad…
