Like any other electronic device, your shark vacuum cleaner can also face trouble after a specific time. Luckily, Shark Vacuum cleaners are simple to fix. If you can figure out the reason for the issue, you can start the troubleshooting process right now. If you are looking for a way to make your vacuum work again like it used to, you are at the right guide. We will cover common problems that every vacuum owner might have encountered and troubleshooting.

Are you worried about a loud suction noise while cleaning your area? Well, it is nothing new. There might be the following reasons that can make a vacuum so noisy. 

A clogged filter is not a good thing for a vacuum. It can block the air cycle on which the vacuum works. And that creates the noise. By removing excess dirt from filters, you can restore the functions of the vacuum. Cleaning filters is a part of regular maintenance of your device. But sometimes, too much dust or quick cleaning sessions can lead to such issues. However, you do not have to worry as it is simple to clean the Shark vacuum cleaner.

Directly open up the lid to remove the dust canister. Empty the canister and clean it. You can rinse it with water and let it dry.

Removing the dust canister will reveal the filter. Here you will see a metal grate. Remove the dirt on it with the help of an old toothbrush. 

Now take the filter and run water over it to remove excess dirt. You can wash it with soapy water too. Let it air dry before installing it back.

Note. You can not wash HEPA filters as they are non-washable. What you can do is, use an air compressor to blow off the dirt. And if you think the filter is in bad condition, you can replace it with a new one as they are not expensive.

Your vacuum can create excess noise if something is stuck inside the inlet. Or the roller brushes are not spinning correctly due to hair strands or dirt particles getting stuck on them. It can make it hard for the vacuum to suck in the dirt, which leads to a noisy cleaner.

Turn the roller brush side up and start examining the issue. If there are a bunch of hair strands stuck on the brush, it will be impossible to take them out with your hands. 

Take scissors and cut them to dislodge. It will make it easier to clean. 

Make sure to check the part from where the suction air goes in.

Do not panic if you notice a sudden less suction power in your vacuum. There are multiple reasons behind this issue. Let us check them in detail below.

The lever adjustment might be causing the issue in your vacuum. Adjust the lever on the lower setting for hard floors like wood and tiles flooring. And set it on medium or high setting for various carpeting types. Maintaining the correct height settings for the right floor type can resolve this issue.

If the filter is loaded with dirt and debris, the air pressure for suction gets compromised and leaves no space for sucked-in air to pass through it. You need to clean the filter following the above steps to restore the suction power.

If you forget to empty the dust bin of your vacuum, it results in low suction. A clean dust bin will solve this problem within no time.

Most of the Shark vacuum models have two hoses. One of them is from head to the base. And the other one is from wand to handle. If either of these hoses gets cracks, it can leak the suction air, which results in lower pressure. Also, check for any blockage in the hose through the torch. Replacing an old one or removing chunks of debris from a hose will make your vacuum work perfectly.

In case you are encountering foul odors after every cleaning session. There is the issue of dirty filters and canisters. Clean the filter and canister as the previous method and apply a few drops of your favorite essential oil to clean filters to freshen up the air in your house after each cleaning procedure,

When you turn on your vacuum, it starts heating up with time. There can be various reasons for that. Such as stuffy filters, overfilled dust canisters, or electrical issues. Due to this condition, the restricted airflow makes it difficult for the vacuum to perform and start heating up. But thanks to a motor protective thermostat that shutdown the vacuum immediately and saves the device from further damage.

Other than filters or duct bins, the vacuum wire can be the reason for overheating. Thoroughly check the wire. If it is frayed, you can replace it. Also, wash filters and dust bin if needed. 

If everything is working fine, but only roller brushes are not spinning. There can be one of two reasons. The roller brush is not moving due to hairs, or the spinning belt is loosened up or damaged.

Clean the roller brush through cutting hairs. If it does not solve the issue, replace the spinning belt. 

Replacing the belt is a comparatively easy job. You only need to buy the matching replacement belt.

Unscrew the plate holding brushes. Remove the old belt that attaches the motor with brushes and make them spin. 

Place the new one in and secure the nuts. Now check if it is working.

From the above information, it is clear that troubleshooting your Shark Vacuum cleaner is an easy job. You can perform each task yourself except if you need to replace the motors.
