I can explain why a vacuum cleaner might lose suction at one end based on how they work.
When a vacuum cleaner loses suction at one end, it's usually due to one of the following reasons:
Blockage: The most common reason for loss of suction is a blockage somewhere in the vacuum cleaner's airflow path. Dust, debris, or foreign objects can get trapped in the hose, wand, or other components, restricting the airflow and reducing suction power. The blockage is often found closer to the end where the suction is weaker.
Filter clogging: Many vacuum cleaners have filters to trap fine dust particles and prevent them from being released back into the air. If the filters become clogged with dust and dirt, it can obstruct the airflow and reduce suction power. Check and clean or replace the filters regularly to maintain optimal performance.
Hose/wand damage: If the vacuum hose or wand is damaged or has small cracks or holes, air leaks can occur, disrupting the suction and reducing its effectiveness.
Bag/container fullness: If your vacuum uses a bag or a container to collect dirt, it may lose suction when the bag or container is full. When it reaches its maximum capacity, the airflow is restricted, causing a decrease in suction power.
Motor issues: Problems with the vacuum cleaner's motor, such as a worn-out motor or faulty motor components, can lead to a reduction in suction power.
To address the issue of loss of suction, start by checking for blockages and cleaning or replacing filters as necessary. Inspect the hose and wand for damage, and if there are any issues, consider repairing or replacing those parts. Additionally, empty or replace the bag/container when it's full, and if you suspect motor problems, it may be best to have it checked and repaired by a professional technician. Regular maintenance and cleaning can help keep your vacuum performing at its best.
