Choosing a Pool Cleaner: Pressure, Suction and Robotic

The device is connected to the skimmer mouth or special vacuum inlet with a hose. The suction created by the pump moves the device on the pool bottom and carries the dirt it collects directly to the pool filter. Since it does not have a separate engine, it has the lowest purchasing cost and its mechanical structure is simple.

The advantage of this type is its economical and less malfunctioning structure. Its disadvantage is that it sends all the dirt it collects to the pool filter; this requires more frequent backwashing of the filter and is dependent on pump operation. Additionally, while it collects fine dust well, its larger leaves may struggle due to clogging. Suction cleaners are a logical economical solution for pools with moderate contamination and a strong circulation system.

They are usually fed from a separate booster pump and fill the dirt they collect into a collection bag on the device itself, not into the pool filter. This means dirt is kept free of the filter system and the pool filter is less burdened.

The main strength of this type is its capacity to collect large pieces, leaves and coarse debris. Since it has its own bag, it does not clog the pool filter. Particularly suitable for ponds under trees or with heavy defoliation. The disadvantage is that most models require a separate booster pump, which incurs additional installation and energy costs. In very fine dust, it may not provide as sharp results as suction or robotic solutions.

It is fed through a power source, dropped into the pool, and with its built-in motors, it scans the bottom, walls, and in most models, the waterline with its own programs. Since they accumulate the dirt they collect in their inner baskets, they do not tire either the pool filter or the pump.

Its biggest advantages are the highest cleaning performance and energy efficiency. Since they work independently of the pool pump, they can clean without starting the main pump and generally consume very low power. Advanced models offer smart navigation, programmable loops and wall climbing. The disadvantages are the highest purchase cost and the need for maintenance due to electronic components. It is the most powerful solution for users with high cleanliness expectations and comfort priority.

All three types can work in small and medium-sized, flat-bottomed pools. However, robotic devices with smart navigation work on stairs, benches and complex geometry pools without leaving blind spots. In large pools, scanning efficiency and cycle time become important, which again brings advanced robotic models to the fore.

The second determinant is the type of pollution: in garden ponds with heavy defoliation, pressure devices with collection bags are comfortable with coarse dirt, while robotic and suction solutions are more successful in pollution with a predominance of fine dust and algae. The third determinant is the budget and plumbing infrastructure. If you have a strong existing circulation, it offers an economical start with suction. Robotics is the right address for those who want the best result independent of the installation. Our company evaluates the geometry, coating and usage profile of your pool project and recommends the most suitable device type for you.

In suction and pressure devices, the tightness of hose connections and the wear of moving parts and brushes should be checked periodically. In pressurized devices, the collection bag should be emptied after each use to prevent clogging. In robotic devices, the internal filter basket should be cleaned regularly and brush and palette wear should be monitored.

Electronic and motor components of robotic devices should be stored outside the pool, in the shade and in a dry environment when not in use. Constantly leaving it in chemically charged water and under the sun shortens its life. It is important for safety that the power supply is positioned so that it does not get water. A properly cared for cleaner will provide years of efficient service, regardless of its technology. For this reason, we recommend that you pay attention to maintenance discipline as much as device selection.
