How to fix a vacuum cleaner with no suction.

What causes a vacuum to lose its suction power?

A vacuum losing suction power is relatively common. There are a lot of issues that can cause this problem, such as:

• The dust container is too full and cannot fit any more dust or debris inside.
• The filter may be clogged or blocked. It must be cleaned or replaced.
• There is a loose connection somewhere in the vacuum that's causing it to malfunction. If all the parts are not attached correctly, it can’t suck up dust and dirt. 
• There’s a blockage in the hose that’s preventing the vacuum from suctioning effectively.
• There’s a technical problem preventing the vacuum suction feature from working.

Steps to fix your vacuum cleaner's suction.

Now, let's dive into the steps to fixing this annoying issue:

Step 1: Grab a screwdriver and your owner's manual.

First, gather all the tools you’ll need. Most models — including bagless vacuums, bagged vacuums, and upright vacuum cleaners — have several areas that are secured by screws. We recommend grabbing a screwdriver.

Tip: You should also settle yourself in an area without carpet, like your garage or yard. The last thing you want to do is spill dust or dirt from your vacuum onto the carpet. Make sure your vacuum is unplugged and that you have enough light to see clearly.

Step 2: Empty the dust bag or receptacle.

If your vacuum’s container is full, it won’t suck up any more dirt. Before you do anything else, check the bag. Empty out the bag or canister completely. 

Step 3: Check the hose for clogs and cracks. 

Another common cause of vacuum suction problems is a clog in a critical area, like the hose.

After you’ve emptied the dirt, hair, and debris from your vacuum's bag, detach the hose. Look inside, and make sure there are no blockages. You can do this carefully with your fingers or with a longer blunt instrument, like a chopstick. You should also make sure the hose isn't cracked or broken.

Step 4: Check the brush bar.

Dust and hair can easily clog a brush bar, hindering the vacuum's ability to suck in dirt and debris. Flip your vacuum upside down, grab some scissors, and cut through the tangled hair. If possible, you may want to dissemble the brush bar to remove all of the debris.

Step 5: Clean the filter.

When was the last time you cleaned your vacuum's filter? If left dirty for too long, a clogged filter can prevent your vacuum from suctioning properly.

Check your owner's manual for instructions. You can clean some filters with soap, but not all. Some vacuums also require periodic replacement of disposable filters.

Step 6: Make sure all parts are connected.

Sometimes, a vacuum won't work and pick up dirt if there's a loose part. Before you turn your vacuum back on, tighten all of the connections and make sure all of the components are attached correctly.

Step 7: Consult a professional or buy a replacement.

Sometimes, a malfunctioning vacuum cleaner belt, motor, fan blade, or blower wheel can cause vacuum issues. If you're handy, follow the instructions in your owner's manual to inspect your vacuum's internal components and replace them.

If you’ve carefully gone through all of the steps above and your vacuum still isn't picking up dirt, call a professional vacuum repair professional. There may be mechanical or technical issues at play that are beyond the scope of even the most handy homeowner.
