There are many kinds of vacuum cleaner bags. If you have purchased a new commercial vacuum please make sure that the bags you buy from now on are compatible with the product you just bought. You cannot imagine how many times I have heard now about people buying incorrect bags for their vacuum. And the worst of all is that some people even bought over 20 of these bags to later learn they cannot be used on their specific model. The good news is that almost all stores allow you today to exchange those product you already bought for the correct ones. I just hope they have the ones that belong to your vacuum model. It is very simple to know what is the correct type of bag needed. Just check out the instruction manuals of the internet to learn what is the right bag model. Many times these models are also made by the same manufacturer, and this makes it easier to find the right bags for your vacuum.
Industrial vacuum cleaners play in a whole different league than commercial product. For example, if you go to a kitchen store or a home depot store, it is very possible for you to find these kind of product and it is very usable. But if you are looking for industrial vacuum cleaners you will need to look for these in totally different places. These product are used in offices, factories or very large spaces, such as stadiums for example. Just imagine how much time it would take to clean out an entire stadium with a regular house vacuum cleaner. One would take ages. This is why we depend too on industrial vacuum in our daily life, to vacuum those big spaces in a shorter time and more efficiently. This is because an industrial vacuum is much more powerful than a commercial vacuum product.
