What makes a vacuum cleaner effective at cleaning?

There is a lot of hype about what makes a cleaner an effective machine these days. Most people believe that a higher amp motor will produce better cleaning performance. While this is a plus it is not always true. There are many classes of high amp motors in the vacuum world. If a motor uses 12 amps it does not necessarily mean it is going to create better suction than a lower amp motor that is better constructed with multiple fans. Motors come in two different forms one being direct air the other being clean air design. Direct air motors are lower amp with a large fan that the dirt flows through and is pushed into the bag. These motors are the best at cleaning because they move more air than clean air motors. This brings us to the misconception that suction power cleans carpets. This idea is false. Air flow and brush action cleans carpets. This brings us to the clean air style cleaners. This design uses a sealed bag chamber and a vacuum motor that pulls the air out of the chamber and dirt through the hose and into the filter system. These motors come in different forms called stages. The amount of stages determines how much air the motor can move. The stages simply put are the number of fans stacked on top of each other to create the suction and air movement. Cheaper motors use small fans and are normally single stage. When choosing a cleaner pay attention not only to the amp rating of the cleaner but also to the motor design and construction for better performance and durability.

The second idea that is false in the vacuum world if that bagless vacuums clean better and cost less than bagged vacuums. The first point to make is to remember the idea that air flow cleans carpet and without proper air flow the cleaner will not be able to remove dirt from the carpet and deliver it to the cup. Bagless vacuums usually are constructed with several filter and sometimes a cyclone system to filter the dirt out of the air. These filter need to be cleaned and changed often putting to rest the idea that bagless vacuums require no further investment after purchase. The second point to make is that if the filters are not maintained they will plug up and not allow proper air flow causing the cleaner to no longer pick up and clog. With this also comes motor strain that will drastically shorten the life of the motor. Lastly people believe that bagless vacuums clean better because they can see all the dirt they pick up. This is false. To illustrate this concept let’s consider a load of laundry coming out of a washing machine and being placed in a dryer for drying. Once the load is dry it triples in size because air fluffs up the material. This is the same for dirt and pet hair. Bagged vacuums compress the dirt in the bag and hold much more than a single tank from a bagless cleaner. The final reason to choose a bagged vacuum over a bagless is that there is no pre filters to clean. The filter bag is the filter and when it is changed the maintenance has be done and the dirt and mess is gone.
