2. CLEAN CANISTERS!
If you have a canister vacuum, get in the habit of emptying the canister after vacuuming, every single time. It keeps odors down & ensures stronger suction when you vacuum next!
3. VACCUUM TWICE
To get a deeper clean on carpets & rugs, vacuum in a north-south motion & then an east-west motion. Especially if you have pet fur... this is very helpful!
