Missing Suction? Solve The Mystery Behind Your Shark Vacuum’S Lack Of Power

If your Shark vacuum has suddenly lost its suction power, leaving you frustrated and unable to clean effectively, you’re not alone. This common issue can arise due to various reasons. In this comprehensive blog post, we will delve into the potential causes behind your Shark vacuum’s loss of suction and provide detailed solutions to restore its cleaning prowess.

Clogged Filters

One of the most common reasons for reduced suction in Shark vacuums is clogged filters. Over time, dust, debris, and hair can accumulate on the filters, obstructing airflow and reducing the vacuum’s ability to suck up dirt. To resolve this issue, regularly check and clean or replace the following filters:

• Pre-motor filter: Located behind the dust cup, this filter traps large debris before it reaches the motor.
• HEPA filter: Situated after the pre-motor filter, this filter captures fine dust particles and allergens.
• Post-motor filter: Found near the vacuum’s exhaust port, this filter prevents dust from escaping back into the room.

Obstructed Brushroll

The brushroll is a rotating component that agitates carpets and helps loosen dirt and debris. If the brushroll becomes obstructed by hair, string, or other foreign objects, it can hinder the vacuum’s suction. To remove any obstructions:

• Turn off and unplug the vacuum.
• Flip it over and locate the brushroll cover.
• Remove the cover and carefully remove any debris or hair wrapped around the brushroll.
• Reassemble the vacuum and test its suction.

Blocked Hoses and Nozzles

Dirt and debris can also accumulate in the vacuum’s hoses and nozzles, creating blockages that reduce suction. To clear any obstructions:

• Disconnect the hose from the vacuum cleaner.
• Check for any visible clogs in the hose or nozzle.
• Use a long, thin object like a pipe cleaner or a coat hanger to gently dislodge any blockages.
• Reattach the hose and test the vacuum’s suction.

Full Dust Cup

A full dust cup can restrict airflow and reduce suction. Empty the dust cup regularly to ensure optimal performance. To empty the dust cup:

• Unclip the dust cup from the vacuum cleaner.
• Hold the dust cup over a trash can and press the release button to empty its contents.
• Reattach the dust cup to the vacuum cleaner.

Worn or Damaged Belt

The belt is a crucial component that drives the brushroll. If the belt becomes worn or damaged, it can slip or break, resulting in reduced suction. To check the belt:

• Unplug the vacuum cleaner.
• Flip it over and remove the bottom cover.
• Inspect the belt for any signs of wear or damage.
• If the belt is damaged, replace it with a new one.

Faulty Motor

In rare cases, a faulty motor can be the cause of reduced suction. If all other troubleshooting steps fail, consider contacting Shark customer support for further assistance.

Troubleshooting Additional Issues

• Vacuum turns on but no suction: This could indicate a blocked hose or nozzle, a faulty motor, or a broken belt.
• Suction is weak on one side: Check for obstructions in the hose or nozzle on that side.
• Vacuum makes a loud noise when turned on: This could be due to a clogged filter or a faulty motor.

Takeaways: Restoring Your Shark Vacuum’s Suction

By following the troubleshooting steps outlined in this blog post, you can effectively diagnose and resolve the issue of reduced suction in your Shark vacuum. Regular maintenance, including filter cleaning and dust cup emptying, can help prevent future suction problems and ensure your vacuum operates at its optimal performance for years to come.
