There are a few possible reasons why your Kärcher vacuum cleaner might not be picking up dirt and debris as well as it used to:
• Check to see if the filters are clogged. Filters that are dirty or clogged can greatly reduce the suction power.
• To keep things running at their best, make sure to clean or replace the motor, exhaust, and dustbin filters on a regular basis.
• A dustbin that is too full can block airflow and suction, so make sure it is regularly emptied before it gets too full.
• Look at the hose and any attachments to see if they are clogged with debris. These can also stop airflow and lower suction.
• Another reason could be a brush roll or floor nozzle that is worn out. If they are tired, you may need to get new ones.
• Lastly, check to see if the seals around the trash can or hose connections are broken or worn. Air leaks can lower the suction power.
