The answer to 'how to clean vacuum yourself' is to regularly maintain and clean your vacuum cleaner. This will help it run more efficiently and extend its lifespan. Start by unplugging the vacuum and removing the dust bag or canister. Use a soft brush or cloth to wipe down the exterior and remove any visible dirt or debris. Next, use a screwdriver or other tool to remove the vacuum's filters and wash them in warm, soapy water. Allow them to fully air dry before reassembling the vacuum. Finally, use a small brush or crevice tool to clean the inside of the vacuum hose and attachments.
Cleaning your vacuum every 3-6 months, or as needed, will help keep it running at peak performance. If you notice a significant decrease in suction power or other issues, it may be time to have a professional service the vacuum.
