MY VACUUM IS LEAVING DEBRIS BEHIND!

Well, that’s annoying. This is a less severe symptom of most of the problems in the previous section. It just means your vacuum is producing some suction, but something’s stopping it from doing its best possible sucking.

Your bag or canister might be full.

-Check your brush. Clean your brushroll and its bearings. If your brush is just a lumbering cylinder of lint and hair, it’s not going to do a great job.

-If it’s not a brush problem, it’s possibly a belt problem. Belts might be broken or too stretched out. They also tend to fall off from time to time. Replace the belt or consult a professional.
