When considering a vacuum cleaner, the most important thing to keep in mind isn't the size of the machine, but what you will do with it and how often. In other words, vacuum cleaners are built to handle certain jobs better than others. Some vacuum cleaners may be prettier than others, but will they be able to go the distance without filling their bags prematurely, especially when required to do the job required on a fairly consistent basis? There is nothing more disappointing than reaching for a vacuum cleaner that is simply not up to the task of even the most basic of things.
Let's begin with suction, virtually the very definition of the word "vacuum". Suction strength is determined by the size of the motor and the volume of air the machine can move. Typically, the more waterlift, the better a vacuum's suction will be.
If the job at hand is to clean a fairly large, flat surface, suction is everything!
In wide area or upright units, the roller should be made of a durable material (metal) and should have brushes that are easily removable for cleaning any strings and fibers that may gather around the roller. The roller is controlled by the motor(s) and is important because it brushes up debris after vibrating it out of the carpet fibers. More power from the motor amounts to more rotations and vibrations of the roller. In a less powerful vacuum, fewer particles will be bounced out of the carpet and will result in a less than desirable outcome. The job will simply take longer and may even need to be redone.
The best commercial vacuum for large buildings is a wide area vacuum. This is because the width of the wide area vacuum allows for fewer passes over a large area. For residential use, an upright vacuum is the most appropriate unit for large carpeted areas.
Suction is also important when using vacuum cleaner attachments, the tools that allow for more specific types of cleaning jobs beyond just normal carpet vacuuming. These tools are defined by the areas they are able to clean. Suction is especially crucial when considering the most basic vacuum attachment, a hose. The longer the hose, the more suction is desired. Length is truly everything with regard to the hose attachment, depending on where you intend to clean. Hoses are handy for vacuuming hard-to-reach areas like ceiling corners and along baseboards.
A wand is a length of inflexible material (metal or plastic) that attaches to the hose. It serves as an extra extension to the hose that allows the user to reach more distant areas. A wand is also useful because it allows the user to fit other tools to its suction opening.
Other options can include attachments with brushes, crevice tools, etc . A brush is a hollow tool with rows of brushes fitted around the suction opening. These brushes scrape up fibers and debris as the tool is manually guided over a surface. The crevice tool, as the name implies, is useful for tight fits such as between furniture cushions or car seats.
