o makes the red light come on. I’ve cleaned the filter and checked around a bit but cannot find out why it’s doing it…?
How to Identify and Fix Common Vacuum Problems ?

What should I do? If your vacuum cleaner whistles, this is usually a sign that your device can`t suck in sufficient air. Often, it`s the dust container or bag that`s full. Check these first and exchange them if necessary.
Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
One of the most common reasons for your shark vacuum (and most vacuums for that matter) making a loud suction noise is because there is a blockage. They`re a very common issue, and easily fixed. Blockages occur when there is a large enough build up of dirt or dust that it blocks the air flow to the vacuum.
One of the most common reasons that the suction may be weaker than expected is a damaged or deteriorating hose. On most Shark vacuums, there are 2 hoses to check: the short hose between the main vacuum head and the base, and the hose between the handle and the wand.
If your machine is making a whistling noise, this indicates that there is a blockage or a damaged or missing seal. Remove the hose from the hose inlet on the front of the machine. Place your hand over the hose inlet and test the suction.
A vacuum leak occurs when air enters the engine from an unintended source. These include a cracked or loose hose, a faulty gasket, or a malfunctioning valve. When this happens, the vacuum pressure in the engine can disrupt. This causes the engine to run rough and produce a whistling sound.
Gravity and friction are the two main forces that make vacuum suction work. While gravity pulls molecules in the air toward the earth, creating an atmospheric pressure, the suction cup and vacuum pump cause a pressure difference, attaching both surfaces.
Handheld vacuums aren`t as loud either, coming in at around 60-70 decibels. Upright Shark vacuums, however, can be as loud as 70-80 decibels since they have powerful motors.
If the tube is making a hissing noise, there could be air leaking from the tube which prevents the vacuum from picking up dust. The tube`s body may have been damaged by fast moving debris or the connection of the tube to the main body could have loosened through the vibration of the vacuum.
Check for a plugged hose
Plugged vacuum hoses are sometimes the reason for a loss in suction. Hoses can get clogged with hair, dust bunnies, string, or anything else that can`t pass through the other end of the hose. Airways inside the machine should be looked at as well. Wherever there is an air passage, check it.
The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
If you listen very carefully, sometimes you can hear a “hiss” sound that is the signal of a vacuum leak. However, the most common way to notice this is when the engine loses fuel efficiency. The reason for this is due to the fact that vehicle exhaust is delayed on exiting the combustion chamber.
Q: What Can I Spray to Check for Vacuum Leaks? A: Any sort of flammable liquid can be used. Carb cleaner, brake cleaner, starting fluid, and propane are all commonly used for the process as they will increase the engine speed when they enter through vacuum leaks.
If the leak is located near the end of the hose, use a pair of pliers to remove the plastic connector from the end of the hose. Then, use a utility knife to cut off the end of the hose above the leak. Replace the connector and reattach the hose to the vacuum cleaner.
All vacuum cleaners operate based on air flowing from the opening at the cleaning head or tool, through the vacuum cleaner and the bag and/or filter system and then out the exhaust port. This airflow is created by the vacuum motor, which also may be referred to as the suction motor.
It is important to check your vacuum filter regularly and replace it when necessary. A clogged air filter will decrease the suction power of your vacuum cleaner and make it less effective at removing dirt and dust from your home.
Suction pressure should be kept at less than 200 mmHg in adults. It should be set at 80 mmHg to 120 mmHg in neonates.
Vacuum suction pressure in adults is 120mmHg.
The lowest vacuum pressure is recommended to reduce the risk of hypoxia and tracheal mucosa injury. However, the pressure has to be strong enough to remove the secretion. Usually, it`s between 80 to 120 mmHg.
Vacuum cleaners that produce less than 60dB of noise are called silent. That doesn`t mean that they don`t make any noise, but you can still hear the TV or easily song along to the radio. Vacuum cleaners with a noise level between 71 and 75dB are loud.
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.
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.
Vacuuming every day, or even a few times a day, is not going to create any long term problems. `But,` you might be thinking, `doesn`t the brushes spinning over the carpet on a beater bar wear it out? ` Sure, but a very small amount.
Most cleaning experts will tell you to vacuum your floors once or twice a week depending on how much foot traffic those floors are getting. Cotter says that high-traffic areas should be vacuumed twice weekly, as these areas have a higher level of dirt, and vacuuming this frequently will prevent matting.
