This depends, among others, on the number of vacuum inlets and the required length of pipe. With the configurator you can quickly and anonymously calculate exactly within 15 seconds how much an AstroVac system will cost in your specific situation.

If you want to order a complete AstroVac system you can do so in several ways. For example, you can first order the rough construction materials (e.g. the pipe system and the fitting kits), and later order the rest (e.g. the vacuum inlets, the power unit, the hose, etc). Do you want to save money? Then choose to order everything at once! Then an attractive all-in-one discount will be deducted! package discount deducted!

The prices in the webshop are shown both including and excluding VAT. You can use the slider in the webshop to indicate how you want the prices to be displayed. Are you a private person? Then choose including VAT. Do you purchase for your company? Then choose exclusive VAT. Do you see a price in a news article or somewhere else and do you doubt whether the VAT has been included? Check the price in the webshop webshop

You can compare multiple products in the same category. Here's how you do this:

  • put a check mark next to each product you want to add to the comparison
  • click on product comparison on the left of the screen
  • click on compare

You can compare up to 8 products with each other. Does the result not fit on the screen anymore? Then use the scroll bar to scroll.

If you want to compare several systems, it is important to get clarity on what is being offered. Sometimes the differences are bigger than they seem. The following questions should at least be asked:

  • are the prices exclusive or inclusive of VAT
  • is the power unit completely filterless, or is it equipped with a filter/dust bag
  • what is the capacity of the vacuum unit (airwatts, airflow, vacuum)
  • are the vacuum inlets made of plastic or metal?
  • does the hose have an on/off switch or (even better:) electronic speed control on the handle?
  • are, and will be, spare parts available
  • is the quantity of tube and accessories comparable
  • does the supplier offer standard PVC tube, or a piping system specially developed for the vacuum system
  • does the supplier have its own service department
  • how many years is the warranty?

The QA vacuum inlet is the same in size as an ES vacuum inlet. QA inlets have a straight design; ES inlets are more rounded. Both vacuum inlets fit into the same fitting kit and are therefore interchangeable. 

The hose length is chosen by you. Standard lengths are 7, 9 and 11 meters. The most frequently chosen length is 9 meters (excluding the handle). We would like to make you aware that a shorter hose (7 meters) is often easier to use. Based on the chosen hose length you can easily determine where to place the vacuum inlets.

A dust bag has a capacity of 30 (!) liters. The average use is 1 dust bag per year.

Clean air ànd optimal comfort

Retraflex is the hose that stores itself. Always within reach and always ready for use. The hose of your AstroVac disappears into the wall. Just as easy and just as fast as you take it out.

With Retraflex, you have a flexible hose at hand for vacuuming in every wall inlet. Storing the hose is no longer necessary. With a simple hand movement it disappears back into the wall!

AstroVac supplies (note!) the original Retraflex 2 materials.

Almost every central vacuum cleaning system in a home, store, office or similar application is assembled with a plastic (PVC) piping system. Plastic does not conduct and therefore becomes somewhat static during use. Because the central vacuum system is turned off automatically after use, the piping system has the opportunity to discharge itself.


It is a myth that anti-static piping systems are available, for example, in PVC or PPC. Also, there are no plastic fittings for piping systems that would not become static. It is said, but again: it is not true! Only grounded metal piping systems are able to conduct staticity immediately.

The tubing should have a large flow-through opening, and minimize the chance of clogging. Therefore, the pipe thickness must be the same as the stop edge in the fittings so that there is a seamless connection inside. A requirement for this is that you shorten pipe at right angles. You can therefore install a central vacuum system using standard pipe, but the chance of clogging is slightly higher. The best result is obtained by using original Better Tube with corresponding original long bends and tees.

A central vacuum vacuum system may clog:

  • if it is not fitted correctly (e.g. with angled bends or wrong materials)
  • if materials are sucked up that absolutely do not belong in a vacuum system (debris, screws, water, etc).

In reality, it seldom happens. And remember: no vacuum system has ever clogged up from dust alone!

If the clog is not severe, you can often remove it yourself using, for example, a de-clogging tool. If
this does not work, call Customer Service for more tips, or call a local service technician.

Often, the central vacuum system is fitted by the installer during construction. Even the handy do-it-yourselfer has no problems with it. Your order is also accompanied by a clear Dutch-language installation manual. It includes many drawings and the helpdesk telephone number. Would you like to know what is involved in installing an AstroVac central vacuum cleaning system?

Then check out the installation manual

This is possible if the house is suitable for it. Meaning that the tubing can be hidden in, for example, an accessible crawl space. As well as in the wall, you can also install the vacuum inlets in the floor.

Do you know (roughly) what you need? With the configurator you can calculate the price of an AstroVac central vacuum system yourself within 1 minute. Simple and fast. Answer the multiple choice questions and let the calculator do the rest. With the + and - button you can adjust the numbers as you wish. Useful if you still have items in stock or if you have already fitted the piping system. After filling out the form you can delete it, print it or add it to your shopping cart.

Would you like to have a custom made design? Or would you like to apply the Retraflex hose storage system? Then go to apply and upload the drawing. You can mention your preferences in the comments. You will receive a detailed quotation for the delivery of the materials, including design and material specification, within a few working days.

Most of the time, the vacuum units are more powerful than you expect. But it may well be that you have higher requirements. Or that you want to use the machine for more or other things than just vacuuming the floors in your home. In case of doubt, you can always consult your supplier or the importer.

No problem. Make sure that the power unit can be mounted vertically.

You can, but we strongly advise you to consult with the importer first. This is among others because of the capacity and the risk of condensation.

From January 2013, all AstroVac vacuum units are suitable for a hose with electronic speed control as standard. Do you have an AstroVac vacuum unit that was delivered earlier? Check with the importer whether your vacuum unit is suitable for a hose with electronic speed control. This is often easy to find out from the serial number.

Want to be sure? Then call +31 (0)76 - 5781581 and keep your serial number handy.

For most, the biggest benefit of a central vacuum system is the clean indoor environment. After all, a portable vacuum cleaner filters the air and then blows this air containing ultrafine dust (microscopic dust particles) back into the room. A central vacuum system, on the other hand, filters the air, and has a connection to exhaust the filtered and never completely clean air to the outside. AstroVac's advice is therefore to always connect this exhaust air pipe to a wall or roof outlet. Then you are really rid of your dust! In addition, you will produce much less noise in the room itself, because the motor noise will also be directed to the outside.

Don't want to, can't or aren't allowed to exhaust air to the outside? Then choose a vacuum unit with an exchangeable dust bag (from the MK series) and equip it with a high-efficiency dust bag instead of a paper one. It is then not necessary (but still possible) to create an air outlet to the outside.

You can, if the crawl space is spacious, dry and well ventilated. With a wooden ground floor, this possibility is not recommended, because of the risk of air leakage.

At your local supplier (usually your builder or installer), or directly from the importer. Dust bags are always in stock and are delivered, just like all other vacuum products, within a 2 working days.

order now

as soon as your order is sent you will receive an email with a track and trace code so you can easily follow your order here How that works.

VacPan is a sweep inlet that is built into the baseboard of a kitchen. Using your hand or foot, you can open the sweep inlet and in the mean time activate your central vacuum. You sweep loose dirt towards the VacPan and it will be automatically removed by the vacuum system.

Visible transport damage:

Is your order visibly damaged? Then refuse the shipment and have the carrier confirm the damage on the waybill. It is also possible that the packaging is visibly damaged but you cannot immediately check whether the product inside is also damaged. You can then accept the shipment but always state on the waybill that you do so 'subject to damage' (OVB). Is the product damaged anyway? Report the damage within 24 hours of delivery to AstroVac customer service, preferably with a digital photo of the damage.

Invisible transport damage:

If the transport damage is discovered only after opening the box, the product has normally been signed for as received and all claims for liability are rejected. In this case, the recipient must be able to make a plausible case that the carrier is to blame for the damage. Report the damage to AstroVac's customer service within 24 hours of delivery, preferably with a digital photo of the damage.

The warranty on a new vacuum unit is 2 years.

Luckily, malfunctions with AstroVac systems are rare, but of course it can happen. The better you can describe the malfunction, the greater the chance that it can be solved by phone. Spare parts are always in stock.

Maintain yourself

Maintenance is mainly limited to emptying and, if necessary, cleaning the unit once or twice a year. AstroVac vacuum units are equipped with carbon brushes. These maintain the electrical contact with the rotating part of the motor and are therefore subject to wear. Unnecessary preventive replacement is not recommended. Your supplier will be pleased to give you maintenance advice tailored to your installation and use.

Have it serviced

You can also have your vacuum system maintained by AstroVac's service and maintenance service. This can be done annually in the form of a preventive maintenance contract, or once-only at an hourly rate. Click here for a free quote.


Such an automatic robot hoover seems handy when you don't want to spend too much time on housework. You turn on the hoover robot, go to work and come back to a clean house. Or does it?

After all, a robot vacuum cleaner can:

  1. not vacuum the stairs
  2. not clean the furniture
  3. not get into corners
  4. not be used to vacuum the car
  5. remove spider webs
  6. not clean loose carpets
  7. not go around vases, cables, shoes etc.
  8. failing to distinguish between dust and pet 'accidents'
  9. frighten small children and pets
  10. consume a relatively large volume of electricity when not in use


A robot hoover vacuums less powerfully, but can often get under low furniture just fine. When you turn a robot on every day, you don't have to vacuum as much. The container where the dust ends up is small. Therefore, you need to empty and clean the tray after every vacuuming. The rotating parts, such as the brushes and the wheels, also need to be cleaned regularly, because hairs and dirt get stuck in them. These parts usually need to be unscrewed. Hairs can be cut off. The filter should be cleaned once a week and replaced every 1-2 months.

A robot vacuum cleaner is a gadget. A nice addition, but never a replacement.

3-phase installations are applied in case of long lasting or continuous use (e.g. in production processes) and in larger premises which need to be vacuumed by several persons simultaneously. With a 3-phase power unit you can vacuum up to 12 persons simultaneously. In addition, 3-phase machines are used with (explosive) hazardous dust. Would you like to know more about 400V installations?
