ᐅ Choosing a Central Vacuum System: Power, Suppliers, Installation?

I am planning a central vacuum system for the renovation of a single-family townhouse. Planning the pipes and inlet valves is relatively straightforward. I will be using a 10m (33 ft) vacuum hose, and the house has three floors (possibly a guest room in the attic), each about 50sqm (540 sq ft). I can place the inlet valve(s) centrally.

However, I am unsure about how to choose the right unit. In our semi-detached house, we currently have a Fewas DuoVac. What I like about it is that the dust filter (a kind of sock over the outlet of the dust container) is washable. This means I don’t want a system that requires dust bags. Emptying the container twice a year and washing the sock filter is fine with me.

Do you have any advice on selecting the performance and brand?

For installing the inlet valves, I have a bricklayer. Do I need an electrician for the installation of the inlets, or how does the control signal get from the inlet valve to the motor? (Maybe I have used the wrong search terms, but I couldn’t find any information.)

Why not use robot vacuums and/or cordless stick vacuums?
Central vacuum systems only have disadvantages.

Yes, central vacuum systems are really outdated nowadays. Expensive and impractical.

There was one in the family home. The strong suction power was a positive, but compared to cordless vacuum cleaners, it was quite cumbersome.

How much does a central vacuum system typically cost? I can also imagine that there are more worthwhile investments.

Whether I really want it is not up for debate. Over the past decades, I have tried everything, including smart robots. Central vacuum systems are excellent! They are in a completely different league compared to conventional devices. You only need to empty them once or twice a year, and they always maintain strong suction power. Still, I have a robot vacuum for some rooms.

Material costs are in the low four-digit range. That fits within my budget.

The question remains: how do I choose the manufacturer? It is important to me to avoid consumables (washable filters would be acceptable).

I don’t understand it any more than the previous speakers... I wouldn’t want to carry the hose around all the time...

To me, it’s like choosing to buy a phone with T9 and SMS nowadays because you prefer it... which is possible, of course...
