The upright style of vacuum cleaner is perhaps the best for large areas of carpet. It is especially good at removing dirt embedded within the pile and pet hairs from the surface, even on sculptured carpets. A drawback with the basic upright cleaner is its difficulty with cleaning stairs. The problem has been overcome with the modern combination of upright and cylinder cleaner. This type may be the best option if you have large areas of fitted carpet and staircases. The motor within the upright cleaner creates the airflow (suction) and drives a rotating brush roll, often called an agitator barrel. Read the rest of this entry »
The domestic vacuum cleaner has been with us now for some 90 years, during which time it has become the most popular labour-saving appliance in the home. The basic principle of operation is quite simple. An electric motor drives fans to create a fast-moving air flow. At one end, a vacuum (suction) of air is created, while at the opposite end the air is exhausted. If the air is moved quickly enough at the inlet end, it will carry with it any debris that enters the airflow. A means of removing the debris from the airflow is required to prevent its redistribution as the air is expelled. Read the rest of this entry »
This type of cleaner, which cleans purely by suction, is better suited to situations other than large carpeted areas: rugs, car interiors, large areas of hard flooring, walls, curtains and furniture. Carpeted stairs are also much easier to vacuum with a cylinder cleaner.
Suction-only carpet cleaning does not remove dirt and grit from the pile base in the same way that the beating and sweeping action of the upright models. However, a machine has been developed that combines the cylinder model with the powered brush roll of the upright vacuum. This type of cylinder appliance has the option of a powered cleaning head attachment that can be connected when required for large carpeted areas. This attachment has a revolving brush roll which is similar to that of the upright cleaner and the suction is supplied by the motor of the cylinder cleaner. Read the rest of this entry »
