The answer to 'vacuum filthy' is that a vacuum that is not cleaning properly is likely due to a clogged filter, full dust cup, or worn brushroll. This can cause reduced suction power and poor cleaning performance.
Some common causes include a dirty filter that needs to be cleaned or replaced, a dust cup that is full and needs to be emptied, or a brushroll that is worn down and needs to be replaced. You may also want to check for any clogs or blockages in the hose or other vacuum components.
Remove and inspect the vacuum filter. Clean or replace it if it is dirty or clogged.
Empty the vacuum's dust cup or canister when it gets full to maintain suction power.
Check the vacuum's brushroll for wear and replace it if the bristles are frayed or the roller is damaged.
Most vacuum filters should be cleaned every 3-6 months, or as needed when you notice reduced suction.
Vacuum brushrolls typically need to be replaced every 12-18 months, depending on usage.
