This is a great article for anyone who wants to learn more about how vacuum cleaners work, which types of cleaning they are best for and what you need to know when buying a vacuum.
Vacuum cleaner types
In addition to permanent-in-the-home central vacuum systems, there are two major categories of vacuum cleaners: uprights and canisters.
An upright vacuum is your best choice if your home is carpeted with low pile synthetic carpeting like nylon, or polyester. However, if you have plush carpet, area rugs, and carpeted stairs, a cannister type vacuum would be best for you.
Uprights usually come with a motorized brush roller that lifts and agitate the carpet fibers for more efficient deep cleaning. The brush may be turned off and elevated while cleaning smooth surfaces.
Nowadays, almost all vacuums have on-board accessories, so uprights are versatile and share many features with canisters.
The cannister is also versatile, practical, and efficient. They can be used on all types of floor surfaces. They are very maneuverable and with available attachments can reach areas that are otherwise hard to access.
Three kinds of cannister vacuums are usually available.
The first type is a straight vacuum with a brush fixed to the floor tool for cleaning hard surfaces or low pile carpets.
The second type has a turbo driven revolving brush. This allows it to function comparable to an upright vacuum.
The third type is fitted with a power brush floor tool that is driven by a seperate motor and is similar to an upright.
