Ducted ⁄ central vacuum systems collects dust and debris as you vacuum from the living area along a series of tubing to finally be collected at the power unit usually located in the garage (bag-less or bagged systems are available.

Ducted ⁄ central vacuum systems are recommended by the Asthma Foundations because they allow for complete and easy dust removal.

Laboratory tests prove that quality ducted ⁄ central vacuum systems reduce allergy symptoms by the following amounts:


Nasal 47%

Non Nasal 48%

Eye 61%

Sleep 44%


Most vacuum power units, (the motor) is located well away from the living areas, usually in a garage… this minimises noise! The vacuum system is accessed through strategically located inlets in the home. The system is activated by inserting the hose into one of the inlets, or by the flick of a switch if a switch was included in the kit of accessories.

All of the dust and debris is collected in a dirt canister or in a disposable bag (depending on the system installed).


A system which uses a disposable bag can collect any dirt/ debris that portable vacuums can pick up. Models which use dirt canisters can theoretically pick up larger and heavier objects because they are deposited in a bin (ie, there is no bag that could be potentially torn or ripped).

Ducted ⁄ central vacuum system should never be used to pick up wet spills.


The dirt canister will need to be emptied between three to five times a year depending on the size of the house, however it can be emptied more frequently if one chooses.


There are many types of filtrations used within the vacuum industry; Mesh filters, paper filters, foam filters, pleated filters, washable filters etc. Although some filters are described as "Self Cleaning" the reality that there is no such thing as a self cleaning filter.

Even though the better quality filters are made from static-free Gortex they still need to be cleaned ever 3 ­ 6 months to remove the very fine dust which accumulates on and around them and maintain good suction. (These quality filters may never have to be replaced but they do require regular cleaning).


Under normal (domestic use), the unit could well last up to 20 ­ 30 years!

Of course this will depend on the quality brand/ model chosen.


Most ducted ⁄ central vacuum systems are significantly quieter than conventional portable vacuum cleaners mainly due to the positioning of the power unit… typically in a remote location such as in a garage, basement, etc.

In addition, ducted ⁄ central vacuum systems are specifically engineered to ensure minimal noise.

Many brands ⁄ models are also fitted with additional sound to reduce motor noise and vibration and or a muffler.

The inclusion of a muffler ⁄ silencer where possible reduces air flow noise from the exhaust vent with an overall result of little or no noise in the living areas of the home when vacuuming.


An installed vacuum system costs a lot less than you might think, particularly if installed in a new home during the construction phase. The actual cost will depend on the size of the home and the number of inlets required, but could be as low as $1,100.00

Another benefit of installing a ducted ⁄ central vacuum system is that it will add value to your home.



Due to new product design features a ducted system can be installed in most homes ⁄ floor plans. As long as there is adequate crawl space in your ceiling and cupboards, pantries or linen closets to utilize.

If you a good handy man you can probably install a system yourself using a D.I.Y. kit, or we can have it professionally installed for you.


A standard vacuum hose will allow you to clean radius of approximately 9 meters, however you need to take into account the position of furniture. You should provide for a sufficient number of inlets to enable you to clean every part of your home.

An average size home will require no more than 3 - 4 inlets! In addition to the inlets in the home most systems provide a utility inlet at the power unit itself so you can clean the area where the system is mounted and particularly useful for vacuuming cars if the unit is located in the garage!


Vacuum performance can be affected at the most distant inlet unless the right system is selected to cater for the size of your home. We can assist you in this regard and are prepared to offer an NO obligation consultation during the planning process.

As we have access to a number of brand ⁄ models ⁄ and we can cater for any size home.


There is virtually no risk of objects clogging the system, for the following reasons:

1) The inlet system is designed for smooth joins and connections, so there is nothing for an object to get caught on.

2) The only sharp angled connection is a 90 deg. elbow behind the inlet. If a blockage were to occur here it is easily cleaned by hand. All other angles are gradual, minimising the chance of blockages.

3) Most hoses are 32mm diameter, smaller than the tubing system therefore if a blockage was to occur, it would most likely be in the hose.

4) In the unlikely event that a blockage should occur in the tubing system then we can generally remove it by using a strong vacuum and suck it back through the clogged inlet


Ducted ⁄ central vacuum systems are designed to be ‘Mostly Maintenance­free’. Filters however do need to be cleaned on a semi regular basis (as previously mentioned). However as dirt canisters (bag les systems) and disposable bags (bagged system) are quite large and will hold large a large volume of debris they will not need to be emptied very often.

We do recommend that it is good practice to have your system serviced every 3 ­ 5 years (depending on use) to ensure your system continues to operate at its maximum efficiency.

When you require a general service we are always available to help you in any way we can.


Ducted vacuum hoses are lightweight and crush-proof.

This means that if you step on, kink or twist the hose it will return to its normal shape!

With no heavy motor to drag around and the lightweight hose you'll find vacuuming easier and a little more enjoyable.


Many customers find it difficult to clean carpet as their conventional floor tool tends to suck down ⁄ stick to the carpet surface thereby making it much harder to vacuum (Making it back breaking work).

If you are experiencing this problem please give us a call and we will discuss an alternative floor tool… a carpet turbine!


You may have inserted the hose into the wall inlet valve incorrectly.


If you are experiencing this problem please give us a call and we will discuss an alternative floor tool… a carpet turbine!

The correct way to insert the switch hose as shown in figs; 1 & 2.

To ensure that your switch hose works properly make sure you insert the end into the wall inlet as far as it will go. The metal band needs to make contact with the contact points in the wall inlet at approximately 12 o’clock.


The wrong way to insert a switch hose as shown in figs; 3 & 4.

If you place the hose in the wall inlet incorrectly you will lose the function of the ON ⁄ OFF switch and the vacuum will start to run continuously… If this happens re­check that the hose has been inserted correctly!

If the hose has been inserted correctly as in fig; 2 make sure the hose cuff is pushed in as far as it will go.


A switch hose allows the operator to control the ON ⁄ OFF function at the handle. This function will allow the operator to turn the vacuum ON ⁄ OFF without having to go back to the wall inlet and unplugging the hose.

This facility is achieved due to the 24 Volt wires which run, along the length of the hose moulding… From the banded cuff inserted in the wall inlet back to the hose handle.


A standard hose will start up your vacuum system as soon as the hose is inserted into the wall inlet, whereas a switch hose allows the operator to control the ON ⁄ OFF function at the handle even if it is still plugged into the wall inlet.


As long as your wall inlets have two metal pins ⁄ terminals inside them then a switch hose will work with your system.

Contact us if you need assistance in this matter.


If you have a standard hose (One without a switch on the handle) if possible remove the banded cuff from one end and temporarily place it at the handle end and then insert it into the inlet valve this will reverse the air flow and may well dislodge the blockage.

If you have a utility inlet on the machine you can do this at this inlet to prevent the possibility of blocking your pipe work.

If it does not clear the blockage you will need to call us for assistance.


Questions regarding a VacPan®

A VacPan® is usually located under a set of drawers, in the kick board usually in a kitchen, or any other hard floor area that often needs cleaning.

Small messes such as crumbs ⁄ spills are simply swept up to a VacPan®, which simply sucks up the mess.

A VacPan® will allow the cleaning up of small ⁄ regular messes without the need to bring out the long vacuum hose.


Check that the lever has been fully turned off.

If the motor is running when it should not, get down and inspect the inlet opening making sure nothing is stuck in it that is preventing it from completely shutting off.

If there is an obstruction in the inlet opening that is stopping it from shutting off remove the obstruction and this should solve your problem… If not contact us for assistance!


Questions relating to disposable bags:

The average size home would need to change a bag perhaps 2 ­ 3 times a year (depending on use)… Some people find that their bag will last them 12 ­ 18 months!

It will vary significantly depending on the type of floor coverings, how big the home is, how often is vacuuming done, how many people live in the home and are there long haired pets in the home.

A bag should be replaced when it is 60% ­ 70% full otherwise you will begin to notice a loss of suction. A bigger problem which can occur is if a bag is not replaced, becomes over filled, loses suction or bursts thereby spilling debris into the container and potentially damage the motor.

Another problem which is sometimes encountered is when the bag is so full that is impossible to removing it without cutting open thus disgorging debris into the vacuum housing.


You should check with your vacuum manufacturer because if your vacuum is under warranty you may avoid your warranty if you use the wrong bag.

Quality bags have the double micro-filter liner that protects the motor against damage for dust and dirt.


No, you need to replace a used bag with a new bag.

Remember, every time you change the vacuum bag you are in fact changing the filter which protects the vacuum from the fine dust ⁄ dirt passing through into the motor.

A good analogy;

Would you put new oil in your car motor and reuse the old filters?


We stock bags for most brands of ducted vacuum systems please call us for assistance.


Ducted Vacuum Tools & Accessories

Regardless of the vacuum brand installed in your home we can assist.

We stock an extensive range of vacuum tools, accessories and consumables that will fit most vacuum systems.


A user friendly vacuum pole ⁄ wand should be adjustable for length to suit the height of the operator. If for some reason your wand is not adjustable then it may be either too long or too short; either way it will make vacuuming uncomfortable.

Please call us for assistance if this is the case.



We have a large selection of wall inlets in various styles ⁄ profiles and colours.

Please call us for more information and to see our colour range.


Questions Regarding Vacuum Installation

Yes, we can install a vacuum system into 99% of existing homes.

As long as there is adequate crawl space in your ceiling, voids in wardrobes ⁄ cupboards or crawl space under your home then this can be done.

This work can be done usually in one full working day, with very little mess or disruption to you.

An installed vacuum system will last 20 ­ 30 years.

Call us for more information… Obligation FREE of course!


Vacuum pipe work is usually installed after the roof is completed, after the electrician and plumber have finished their work and of course before the plasterer sheets the walls.

In some cases it is necessary to place vacuum pipes under a concrete floor, if this is the case you need to contact us much earlier.


You need to decide before or at the time the pipe work is being installed.

Different wall inlets will have different mounting brackets plates therefore it is important to decide before running the pipe work through the ceiling ⁄ walls.


No, generally one wall inlet will cover an area of about 80 Square metres.

The average home needs 3 and 5 inlets in order to cover the whole floor area depending on the design constraints of your home.


No; All vacuum units can be attached to pipe work but we should discuss price, which power unit will best suit your needs and what vacuum tools ⁄ accessories you would like with your system. Give us a call to find out more. Phone 0800 354 948


Your system is finished off with the power unit is attached to the tubing system, and the wall inlets fitted. Generally after the painting is completed, the kitchen units have been installed and the carpet laid.


Preventative Maintenance

Check to see if the bag is full and replace if necessary (Replace when 70% ­ 80% full) otherwise suction will deteriorate and may even burst if left too long and potentially damage the motor.

If the bag does not need to be replaced then check all your inlets to see that they are fully closed including the VacPan (if you have one).

Plug your hose into the inlet closest to the power unit and walk around your home and listen for any air leaks. If you hear an air leak check the inlet and remove anything that may be keeping it open.

Plug your hose into each inlet to see if there is a loss of suction at all inlets. If there is the same loss of suction at each inlet try the following.

Check that the vacuum lid is on properly closed and making a seal against the drum.

Lift the grate under the disposable bag to check if debris/fluff has sealed the orifice which the vacuum motor draws air from.

Check that all wall inlets have lid rubbers on the inside of the flaps.

If you still have a loss of suction problem contact us for assistance.


Do you have a VacPan installed where you sweep the dust/ dirt up to?

If you do, check that the lever is fully closed and that there are no objects that could be stopping it from shutting off completely. Open the VacPan and remove any object that prevents it closing properly, turn the lever to the off position, hopefully this has solved the problem.

If you still have a problem, contact us for assistance.


Yes we service ⁄ repair ⁄ maintain and can replace ALL vacuum brands.

We also maintain a large inventory of, vacuum motors and spare parts for most brands of vacuum systems including but not limited to; Astrovac, Auskay, Beam, Bosch Siemens, Cyclovac, Electron, Eurovac, Hayden, Hills, Hoover, Modern Day, Premier Clean, Pullman, Smartvac, Silent Master, Tornado, Ultra Clean, Volta, Vacu­Maid.

Although your system has been designed for maximum performance and service life, there are some guidelines you can follow to help prolong its efficiency, serviceability and its useful working life.

1) When removing the hose from the inlet valves, hold the wall inlet lid open for three (3) to five (5) seconds after removing the hose (until the vacuum stops running).

2) Never vacuum up liquids of any kind with your vacuum system. If you accidently do, leave your hose plugged into the inlet valve and let the system run for approximately five (5) minutes, without vacuuming anything up.

3) Doing this will help to dry out the vacuum hose and pipes running through the walls.

4) If you don’t do this and continue to vacuum dust and dirt will stick to the walls of your hose and pipes and over time will reduce the performance of your system.

5) Never attempt any internal repairs on the power unit.

6) Please call us for assistance if these type of repairs need to be done.
