If your Shark vacuum smells when turned on, even if the filters are clean, there could be a few potential reasons for this issue:
Odor from the brush roll: Over time, debris, pet hair, and other particles can get trapped in the brush roll or bristles. When you turn on the vacuum, the brush roll spins, and the accumulated debris can release a musty or unpleasant smell.
Clogged hoses or airways: Even if the filters are clean, there might be clogs or blockages in the hoses or airways of the vacuum. These clogs can trap dirt and moisture, leading to odor when the vacuum is operating.
Dirty dustbin or canister: If the dustbin or canister where the dirt and debris are collected is not cleaned regularly, it can accumulate grime and cause a foul smell when the vacuum is turned on.
Mold or mildew growth: If moisture gets trapped inside the vacuum or its components and is not allowed to dry properly, it can lead to mold or mildew growth. This can result in a musty smell.
Worn or dirty filters: While you mentioned that the filters are clean, it's still worth double-checking to ensure they are in good condition. Worn or dirty filters can reduce the vacuum's ability to trap odors and particles effectively.
Here are some steps you can take to address the smell issue:
Clean the brush roll: Remove the brush roll and clean it thoroughly to get rid of any trapped debris. Ensure it's completely dry before reassembling it.
Check for clogs: Inspect the hoses and airways for any clogs or blockages. Clear out any debris that you find.
Clean the dustbin or canister: Empty the dustbin or canister and wash it with soap and water. Allow it to dry completely before reassembling it back to the vacuum.
Inspect for mold or mildew: Check for any signs of mold or mildew growth inside the vacuum, and if found, clean it using a mild cleaning solution or a mixture of vinegar and water.
Replace filters: If the filters are old or damaged, consider replacing them with new ones. Filters should be replaced periodically to maintain the vacuum's performance and reduce odors.
Allow for proper drying: After cleaning or using the vacuum, make sure to leave it in a well-ventilated area to allow any residual moisture to evaporate, preventing mold growth.
By following these steps and maintaining your Shark vacuum regularly, you should be able to minimize or eliminate any unpleasant smells when using the vacuum.
