Step-by-Step Repair
- Step 1 of 61
Check and clean the filter
Remove and clean all filters. Wash them with water if the manufacturer allows it, and let them dry completely before reinstalling. A clogged filter is the most common cause of performance loss.

Inspect all hoses, nozzles, and openings for obstructions. Remove any debris, clogs, or buildup you find.

Empty the collection container
Make sure the dust bin, bag, or tank isn't full. Many devices reduce performance automatically when the container is near capacity.

Inspect seals and gaskets
Check all connection points for air or water leaks. Loose or cracked seals reduce performance significantly. Reseat or replace damaged seals.

Use compressed air or a brush to clean the intake vents and exhaust areas. Built-up debris in these areas restricts flow and reduces performance.

When to Call a Professional
Most vacuum issues are maintenance-related (filters, clogs, brush rolls). If the motor makes a burning smell or has stopped working, motor replacement is usually not cost-effective. A new vacuum of similar quality costs $100-$300.
