It happens to all of us. You are vacuuming in your house and all of a sudden you notice that the vacuum is not picking up any more trash or dirt. You go over the dirt again. Still nothing, its still there. Its the bag. It needs to be changed. What do you do?
First you need to open to compartment to your vacuum. Do it slowly because there is going to be a lot of dust mites floating all over the place.
Next you are going to need to take the bag off the pipe leading into it. This is not that hard at all. You may have to loosen up a clamp of some sort but usually all you will have to do it pull it down. Again, dust will probabely be flying all over the place.
Take the bag off and notice what kind it is. Write it down. There is going to be a size and a number. Write down as much information as you possibly can.
Head to the store. You can get vacuum cleaner bags at any major store like Target, Wal Mart, Fred Myers, Kroger, Randalls, ect. Go to the home cleaning section and you will easily find them. Most stores usually have a few main brand name bags but most of them will be generic. I would recommended getting a couple of them as they are not that expensive and its nice to have a couple as backup should you need them in the future.
Get the right bag and take it home with you. Connect the bag back to the vacuum and make certain that it has a good seal. Turn it on and test it out. You should be able to vacuum up the dirt now. If not than you do have have the proper seal.
You are all set. Usually most bags will last for several months.
