This is the age-old question that can vary from person to person, place to place, and expert to expert. Do you vacuum first then dust or do you dust first and then vacuum.
At the end of the day it is easier to dust from top to bottom and then vacuum; if you are doing them both during a routine cleaning session. Sometimes you may dust on one day and then vacuum another day. In the perfect world and perfect scenario, it is recommended that you dust first and then vacuum. However, my suggestion is to do what works best for you, your home, and your schedule.
The most common issue with vacuuming first is the reappearance of dust/dirt on the items you recently dusted. The best way to avoid this issue from happening should you vacuum before you dust is to perform PROPER MAINTENANCE on your vacuum cleaner. YES, maintenance. This is one of the major appliances that gets neglected the most as far as maintenance is concerned. Most vacuums are used until they no longer work which typically happens from uncleaned filters and canister which leads to loss of suction and more stress on the motor. It is important and I always recommend to clients to clean the filters and canister of their vacuum to get the longest life out of it and to avoid the reappearance of dust/dirt onto your furniture and floors. This can be done by following the manufacturer’s instructions on how to properly maintain your vacuum or central vacuum system.
Overall, effective vacuuming can only work if maintenance is done on a regular basis. So regardless if you dust first then vacuum or vacuum first then dust, the end result will be the same with a poorly maintained vacuum. As stated above, do what works best for your home and schedule.
