Why is my vacuum cleaner losing suction?

Common causes and solutions for vacuum suction power loss

Your trusty vacuum cleaner has been your partner in crime when it comes to battling dust and keeping your living space pristine. However, there comes a time in every vacuum’s life when it seems to lose its once mighty suction power. Before you start contemplating the purchase of a brand-new vacuum, let’s explore the common reasons behind this power loss and discover some simple DIY solutions to breathe life back into your faithful cleaning companion.

Understanding vacuum cleaner suction loss

Vacuum cleaners work by creating a suction force that pulls in dirt and debris from various surfaces. If your vacuum is losing suction, it means that something is hindering this process. Let’s delve into some common causes and practical solutions.

Clogged filters

When filters become clogged with dirt and debris, they restrict the airflow, leading to a decrease in suction power.

• Locate the filter in your vacuum cleaner (refer to your user manual if needed) and inspect it for any visible debris. If it’s washable, give it a thorough cleaning.

Start by cleaning the canister

• Unplug your vacuum and take out the canister.
• Wipe away dust and buildup with a soft cloth.
• Rinse the canister in warm, soapy water, and let it air dry completely before putting it back.

Clean the filter

• Locate the filter and remove it. Tap it against a hard surface to get rid of excess dust.
• Save time by using a vacuum or air gun connected to a compressor for thorough dust removal.
• Rinse the filter under cool tap water—no detergent needed.
• Let the filter air dry for 24-48 hours or until completely dry.
• Once the filter is entirely dry, put it back in the vacuum.

For non-washable filters, consider replacing them regularly to maintain optimal performance.

Full dustbin or bag

A common oversight is neglecting to empty the dustbin or replace the bag regularly. When the bin or bag is full, airflow is restricted, leading to decreased suction power.

• Empty the dustbin or replace the bag before it reaches maximum capacity. Check for any debris lodged in the dustbin compartment and remove it.

Blocked hose or attachments

Your vacuum’s hose and attachments are the pathways for dirt to reach the dustbin. If any part of this system is blocked, it can significantly reduce suction power.

• Disconnect the hose and attachments, inspect them for blockages, and use a broom handle or a straightened coat hanger to gently dislodge any debris. Be sure to check the entry point into the dustbin as well.

Cracked hose

Inspect your vacuum hose for any cracks or damage. A hose with cracks or holes allows air to escape, diminishes pressure and hampers the smooth airflow required to pick up and contain dirt.

• Replace any cracked or damaged hoses to get your vacuum working at its best again.

Dirty brush roll

The brush roll, located at the bottom of your vacuum, plays a crucial role in agitating and lifting dirt from carpets. Over time, it can get tangled with hair and debris, hampering its efficiency.

• Turn off and unplug your vacuum. Flip it over to access the brush roll. Remove any hair or debris wrapped around it using scissors or a utility knife. Regularly cleaning the brush roll prevents future clogs and ensures effective cleaning.

Leaking seals or gaskets

Inspect the vacuum’s seals (gaskets) for any signs of wear or damage. Leaks in these areas can compromise suction power.

• Carefully examine the seals and gaskets, replacing any that show wear or damage. This ensures a tight seal and maintains optimal suction efficiency.

Damaged belts

The belts in your vacuum are responsible for turning the brush roll. If they are worn out or torn, the brush roll won’t spin properly, leading to a loss of suction.

• Turn off the vacuum and disconnect the power. Access the brush roll and inspect the condition of the belt. Replace any damaged or loose belts, following the manufacturer’s guidelines.

Motor issues can affect vacuum suction loss

In some cases, the motor itself may be the source of suction loss. If the motor is malfunctioning or has burnt out, it will impact the vacuum’s overall performance.

If you’ve ruled out all other causes and suspect a motor issue, it’s advisable to seek help from a qualified technician.
