Recapitulating on the most crucial aspects of buying a vacuum cleaner -

CONFIGURATION OF VACUUM CLEANERS

Based on the configuration of components, vacuum cleaners can primarily be classified into two types, namely:-

1. Bagged Vacuum Cleaners

2. Bag-less Vacuum Cleaners

Bagged Vacuum Cleaners

This configuration of vacuum cleaners typically makes use of five components to get the entire cleaning operation done. Those are:- An intake hose, An electric motor, A fan, A collecting bag and An exhaust port.

As the vacuum cleaner is turned on, an electric motor starts spinning at high RPMs. The electric motor is attached to a fan that creates low pressure towards the suction side of the intake hose. This pressure is significantly lower than the atmospheric pressure present in the surroundings, and because of the low pressure inside the suction hose, air from the surroundings is sucked into the intake hose, as air moves from area of high pressure to low pressure, thereby taking the dust and debris up the hose towards a collecting bag or a bin.

The collecting bag is made up of porous woven material which acts as an air filter. The pores on the bag typically range between 0.3 to 1.5 micron in diameter thereby trapping all the dust and debris from the air. This relatively clean air makes its way out of the bag into the surroundings through an exhaust port.

Bag-less Vacuum Cleaners

The working principle of bag-less vacuum cleaners is very similar to that of bagged ones, except for the fact that instead of a collecting bag that collects all the dust and debris, bag-less vacuum cleaners make use of a collection bin known as a canister to collect all the mess.

Bag-less vacuum cleaners can be sub-categorized into three types based upon their cleansing mechanism:- 

1. Wet & Dry vacuum cleaners

2. Cyclone vacuum cleaners 

3. Robotic vacuum cleaners

Wet & Dry vacuum cleaners 

This sub-category of bagless vacuum cleaners has a HEPA/special cartridge filter fitted inside the canister which filters out dust and debris before they get accumulated in the canister. 

The fan driven by an electric motor creates low pressure towards the suction side of the intake hose. Due to significant difference in the atmospheric pressure and the pressure created by the fan, air along with all the dust and debris gets sucked into the intake hose and moves towards the dust holding canister. The air, free from dust and debris is expelled out of the exhaust port after passing through a HEPA filter that virtually traps all the microscopic and large particles, including allergens and mould before expelling them out through the exhaust port, thereby facilitating sanitized air in the home. 

Cyclone Vacuum Cleaners

Cyclone vacuum cleaners are a very popular choice among buyers. They work on the principle of centrifugal force to eliminate dust and debris from the sucked air.

Air along with dust and debris enters the intake hose pipe because of the low pressure created by the fan. At the other end of the intake hose, air laden with dust and debris encounters a vertical cyclonic separator which is a cylindrical device with a conical bottom. The mixture of air and dirt enters the cyclonic separator from an inlet port located on its wall and travels down the cavity of cyclonic separator at high speeds in a helical fashion. Dust and debris being heavy in comparison to air are unable to follow the helical path and rather strike the walls of the cyclonic separator, thereby losing all the momentum, which results in them falling towards the conical bottom of the cyclonic separator where a canister is attached to collect all the mess.

Robotic vacuum cleaners
This category of vacuum cleaners has gained lot of appreciation in the past few years, and perhaps for all the good reasons. Robotic vacuum cleaners rely on their multiple onboard sensors to help them determine the path they are following and the area of the floor they need to clean. One of the onboard sensors, the pizeo-electric sensor, generates electrical impulses when something strikes it, in this case, dust and debris. When dust strikes the pizeo-electric sensor, the sensor directs the robot to move slowly over that region such that dirt can be effectively cleaned. The robot can effectively clean the locations that conventional vacuum cleaners can not, such as, beneath the tables, under the beds, etc.

The greatest advantage of robotic vacuum cleaners comes from the fact that they do not require any sort of human intervention. Once directed to perform the cleaning operation, they autonomously get the job done. Robotic vacuum cleaners work wonders in homes where working members have a hectic work schedule and remain at workplace for most part of the day. However, they are not a substitute to conventional vacuum cleaners and should be used for minor cleaning purposes and for catering to the difficult sites that the conventional vacuum cleaners can not reach.

COST CUTTING TECHNIQUES

• Low-grade overheating electric motor. The electric motor rotates at very high RPMs to power the fan that creates low pressure inside the intake hose for suction to take place. This makes the electric motor one of the most crucial components of the vacuum cleaner and therefore accounts to almost 30 per cent of the entire cost of the product. Hence, it is one of the favourite areas of some manufacturers to cut costs and increase their profit margins. Some manufacturers resort to using a below-par electric motor that is not powerful enough to keep the fan rotating at high speeds for long periods of time. After only a few minutes of use, these electric motors tend to get extremely hot. As you might be aware that metals expand on heating, which causes the copper windings in the motor to initially distort and then finally melt, thereby leaving the vacuum cleaner unit out of operation. Cost of repairing the motor might range from a few hundred bucks to more than a thousand bucks and this process is recurring.

• Inefficient rubber gasket and seals. To facilitate airtight operation so as to prevent dust and debris from leaking out of the canister, rubber gasket and seals are provided around it. These seals and rubber gasket do a fantastic job of withholding the mess inside the canister and prevent it from going back into the surroundings. However, high quality seals and gaskets are costly. Therefore, in order to reduce the initial cost of the vacuum cleaner so as to lure the customers, some manufacturers resort to using inferior quality rubber gasket that starts to develop cracks and incompetent seals that lose their adhesive characteristics only after a few months of use. This makes the canister lose its airtight properties. As a result, the accumulated dust and debris might escape back into the surroundings, rendering the cleaning operation less effective.
