The central vacuum system is the electrical appliance that is used for cleaning the debris and dust around the building as a semi-permanent fixture. It collects the dirt and debris around the house and buildings and sends it to remote utility space through the internally installed tubing. There are various parts of the central vacuum system and in fact, all the parts are involved in performing different tasks. It is basically used for removing the dust particles and debris around the house. It is useful as it reduces the tedious task of cleaning and saves the time for the consumer.

In addition, as the dust and debris are not emitted outside the vacuum system so it does not create any unpleasant smell around the house. The use of central vacuum system offers many advantages to its customers or users. Its increased suction power offers extra power to pull the dirt out. It also effectively removes the difficult hard debris like plaster, broken pieces of glass, silver & lead and worn out electrical wirings. It also offers the safe and complete removal of the allergens and unbearable smell and odor as it does not circulate the exhaust air back into the cleaning space.

The noise produced by the central vacuum is not that much aloud it is very quiet at the point of the use. The setup and the cleaning process are not very technical it is user-friendly. The cost of operation and electricity consumption is economical and there is no ongoing cost of the cleaning process. It consists of a vacuum hose, vacuum hose, pipe & inlets and the cleaning Vacuum tools such as vacuum accessories. Maintenance of the central vacuum system is important for the smooth functioning of the system, which is as such not a technical task, only some precautionary measures and few steps should be kept in consideration. In addition, the maintenance is of the following task is necessary:

  • Filter
  • Hose plus vacuum head care
  • Motor
  • Electronic core
  • Inlet system care
  • Troubleshooting


Filter Maintenance:

The basic filter maintenance includes the bag changing, dirt emptying and cleaning the main unit. If you want to clean the filter then you are suggested to remove the base of the specific unit through a twist. It may be difficult in the case when the unit is full of dust and debris. When the bucket has been opened, take out the debris into the plastic bag and hold it tightly while shaking it firmly so that filter is free of all type of entrapments. Then remove the centrally weighted filter and firmly pull it inward and the filter will drop out. Washing of the filter is not recommended as on washing there is a chance of sticking of debris between the layers. Use of full filter reduces the efficiency of the vacuum and there is a chance that vacuum becomes hotter in less time.

Motor Maintenance:

The central vacuum has sealed motor in their collection unit as the main processor. For their functioning, they as such do not need any lubrication or oiling. All it needs is the weekly or monthly cleaning. Motor brushes should be checked routinely and it should make sure that the central shaft of the motor has as such no threads or wobbles attached. If such issue is identified then measures should be taken as it indicates that the motor is going to worn out soon and in case of the damage to the brushes is extensive it is a good idea to change the motor.

If the motor is not covered with any paper or cloth bag then there is a high risk of accumulation of debris on the motor shaft, blade, and internal brushes. If this is happening then the damage could not be prevented by cleaning the blades and brushes may offset the balance of the blade and fan that will result in the premature failure of the motor. The balance of brushes is crucial as they conduct the electricity by touching the central shaft of the motor. In case of replacing the motor, care should be taken as false motor could damage the entire system.

Motor Brushes

Each motor contains two carbon brushes that are pivotal in conducting the electricity from shaft to the motor. These brushes are replaceable once they are worn out but the replacement should be made according to the required size as the wrong size could cause more damage than repair. For keeping the original brushes in the steady state they should be checked routinely. Sometimes it is recommended that instead of changing the brushes change of motor.

Hose & Vacuum Head Maintenance:

A hose is the most expensive and crucial part of the vacuum and the proper maintenance will help in lasting the viability of the hose. It should be stored on the hose hanger when not in use. A non-stretchable cord should be used with the vacuum as stretching cord could be a source of voltage failure. By storing it along with the vacuum wands there is a higher chance of the occurrence of the stress fractures. The most effective and easy way to store it on the hanger is to bend it in form of four or five loops keeping it on the floor and then tying the loops altogether to the hanger. More loops should be avoided as it would create a mess in unwinding the pipe. The use of hose cover should be taken into the consideration as it would help in the long-lasting use of the hose and in turn vacuum. Along with the hose, carpet brushes should be kept clean and smooth by taking care of them. Routinely arrangements should be made for trimming the extra or long fibers of the brushes or the treads that are wrapped around the brushes. The roller brush should be rolled in the balanced state as it is required for the conductance of the current and efficient cleaning. Because of incredible spin, there are great chances that bearing will be imbalanced and ultimately, it will lead to premature failure of the bearing. The brushes of the motor will also be affected. So to avoid imbalance vibrations and friction should be minimized.

Inlet & Pipe System Maintenance:

The principal concern in designing the central vacuum system is reducing the situation where any clogging in the inlet and piping could cause the undesirable circumstances. The best way to reduce the clogging of the inlet is its inbuilt function of the safeguard at the entrance of the inlet which is built on the purpose of reducing the curvature so that any particle that could interfere with the functioning of the system should be avoided to go inside the pump and motor. The other benefit is that any clogging particle got stuck at the start of the inlet where it is easy to discover and remove. A typical house set up requires 3-4 inlets for one floor. After the installation additional inlets could be adjusted separately for each floor, garage, and attic etc. You should be very careful while placing the inlets. Convenient places should be selected for the purpose as open door or furniture could interfere with the working of the system. Inlets and the pipe system maintenance along with all the other parts should be regulated on the routine basis and piping and the wiring should be kept in proper place so that loses could be avoided. Inlets could get old or could lose positions inside the inlet and the pipe or the missing air could be a source of islet damage. If the inlet gets worn, the whole of the inlet system has to be replaced not only the specific part of it. As the individual parts are not available, but it is not that much expensive so could be easily replaced. The system pipes should last a lifetime if they are installed and maintained properly. If they get dusty with the debris then the best method is to clean them with the wet and soapy cloth. The cleaning of the inner of the pipe is recommended in a year. For the cleaning free flow sheets could use that pulls out all the debris and dust out of the pipe system.


One could diagnose the problems of the system by Interactive repairs Solutions Guide that is related to Central Vacuum. In this program, the consumer could get guidance through simple, practical and method wise finding the solution of the problems. The problems that could be solving through the program are:

  • Hoses
  • Switches
  • Vacuum Heads
  • Motors
  • Issues of low suction
  • No suction
  • Low or high voltage issues
  • Running unit problems
  • Inlet clogging
  • Hose repair

After troubleshooting, if one is still unable to find the exact solution to their problem then it is recommended to contact to any skilled personnel. Although it is a user friendly appliance it also poses a significant risk of building fracture where it is installed. The fracture to the building pose by its fixture is permanent. The initial installation cost is also greater as compared to other vacuum systems but it could be compensated with the long-term benefits that one could enjoy after its installation.
