Take your time if you want to thoroughly clean your carpet. Remove any obstacles, including large garbage, by hand before starting. Check your vacuum’s filters and bag or canister to ensure they are not clogged or too full to do the cleaning task. You should also gently vacuum in neat, slightly overlapping rows. If you rush through this step, you are more likely to miss deeply embedded dirt in the carpet strands. Once you’ve reached the end of the carpet, go over it again in the other direction to ensure that every last bit of dust and filth has been removed.
