If you starting running into a situation where your vacuum just doesn’t have the strength that it used to there are a few things you can do to really check if it is the vacuum itself or just a component or part of the vacuum. Don’t be scared to pull out some tools and check it yourself, it could save a few hundred dollars buying a new vacuum. A few years back I had a vacuum that was only a few years old that could even pick up a grain of sand and after investigation I found a clogged hose, cleaned it out after that the vacuum was able to pick up golf balls.
Things to check:
1. Filter: Often times it is just time to replace the filter in your vacuum. If you notice that when you run the vacuum it gets kind of stinky in your home or office chances are that filter has more dust and crud built up in it than a treasure chest. When you remove it make sure to have a trash near by because a great deal of debree will fall from it and try to do this out doors if at all possible because it will release some dust into the air. this dust could be very old.
2. Tubing: Tubing on vacuum cleaners is relatively narrow in diameter so it will be crucial to check as much tubing as your handiness will allow for. If you are at all handy or even know how to unscrew a phillips head screw try removing some of the tubing anywhere where there are tight bends because it is very possible over time you could have a build of dust, hair, thumb tacks whatever it is thats on the floor. If you have a pet there could be a great deal of hair stuck in the tubing.
3. Other: If the two options above yield no results than take into account the age of your vacuum and what you have put it through. if you have been vacuuming your workshop with it for the last 5 years than it might just be on the way out but if you recently bought and it hasn’t touched too much more than a nice plush carpet than dig up your owners warranty because you might just need a replacement vacuum.
