Central vacuum cleaner units - the heart of the central vacuum system
Vacuum cleaner central units are a key element of every central vacuum system. In our offer you will find a wide selection of high quality units. These are devices of different power and efficiency. We select them for specific needs and conditions.
We often hear about the advantages of central vacuuming. There are many. First of all, it is the convenience of use. You no longer have to carry a heavy vacuum cleaner around the house. Just connect the hose to the suction socket in the wall. The system works quietly. The central unit is usually located in the garage or basement.

How to choose the right central unit for your vacuum cleaner?
Choosing the right central unit is a key issue. It affects the efficiency of the entire system. When choosing, we take into account several factors:
- The area of the space being cleaned
- Number of suction sockets in the installation
- Length of installation cables
- Type of surfaces cleaned (carpets, parquet floors, etc.)
- Special requirements (e.g. allergy sufferers at home)
Our experience shows that a properly selected unit is the basis for user satisfaction. That is why we always advise individually. We analyze the needs of each client. We propose the best solutions.
In everyday practice, we see how important the power of the unit's engine is. For a small apartment, a model with a power of 1300-1500 W is enough. A large house requires a 2000-2500 W unit. The capacity of the dust container also matters. In apartments, 20-30 liter models will work well. Large houses need 40-60 liter containers.
Another important issue is filtration. The latest units have advanced filter systems. They stop even the smallest dust particles. This is especially important for allergy sufferers. We recommend models with HEPA filters. They stop 99.97% of particles as small as 0.3 microns.
Practical applications of central vacuum cleaner units
Central vacuum systems work well in a variety of facilities. We recently completed a project for a large office building. We installed an efficient central unit there. It serves 5 floors of the building. The cleaning service employees are delighted. Work has become much easier and faster.
Another interesting case is a hotel by the sea. The owner decided to install a central vacuum system. We chose a high-power unit. It copes well with sand brought in by guests. The cleaning staff praises this solution. The rooms are clean and the work is less tiring.
In the case of single-family homes, we often install smaller units. They work great. Users praise the quiet operation of the system. They also appreciate the fact that dust does not float in the air during cleaning. This is a huge advantage for allergy sufferers.
It is worth mentioning the special applications of central processing units. In car workshops, we install industrial models. They can handle metal shavings or grease. In carpentry workshops, we install units with separators. They collect shavings and sawdust without losing suction power.
An interesting trend is the installation of central units in campers and caravans. We use compact models with low power consumption there. Thanks to them, maintaining cleanliness during travel becomes much easier.
