Hydraulic pool cleaner: why buy it?

Hydraulic pool cleaner

The hydraulic pool cleaner is automatic robots powered by hydropower. Here is the first difference with the electric ones, which work with motors powered by electric power and with the manuals, which do not need more energy than the one that already uses the system itself. But the effort of someone who directs them throughout the pool.

Basic characteristics of a hydraulic cleaner

Hydraulic cleaners are easy to install and use. They collect the dirt from the bottom of the pool, installed in the filtration circuit of the pool. The waste that is collected in the pre-filter of the pump or sent to the skimmer basket of the pool.

They perform the cleaning autonomously, so they do not require user control to navigate the bottom. They do not brush the floor as other models do. But they suck the dirt, and do it randomly, without an order. This means that for the fund to be clean they must take more time than the electric ones, or even the manuals.

They do not have the ability to identify and overcome obstacles. So they will not go up ladder rungs, and according to the model, they will not climb walls either. In fact, you may get stuck when you meet them. However, specific pool cleaners can be purchased for flat, sloped, oval or rectangular surfaces, and work well with any coating.

You can find two types:

  1. Aspiration: they connect to the skimmer or to the pool cleaner, and run randomly through walls and floors propelled by the same filtration system.
  2. By pressure: It is connected to the return of the pool, and are also propelled by the purification system. They usually require the installation of an extra pump (which will consume more electricity) and have filter bags to hold solid waste. In this way, they do not reach the pre-filter of the pump.

To work well, they need a high flow that allows movement, then they are not suitable for any type of pool, or you need, as we have said, additional pumps near the filtration equipment.

For its operation, in addition to the robot itself, hoses are needed, automatic flow regulation valve (or flow meter if it is models more than three years ago) and supplements and adapters for the connection. They are indispensable accessories.

When it is going to be used, it is necessary to start the filtration system of the pool, making sure that the pre-filter of the pump is clean. The return nozzles of the walls must be oriented correctly, downwards.

Once the pool has been prepared, the necessary lengths of hose must be connected so that they reach the corner farthest from the pool from the point of connection. You must also use the adapters to connect the device later.

Then the equipment is installed, either using a suction socket or one of the skimmers in the pool. In each case, the appropriate connectors must be used, which must come with the equipment, in addition to the flow regulation valve. It must be submerged in the water and connected to the hose to start working.

Each machine works in a specific way, but these general notes also help to know the characteristics of the hydraulic cleaners.

Why choose a hydraulic?

Although the hydraulic cleaner has its limitations compared to other models, they work autonomously and do not require electrical power. In addition, they are much more affordable and do not need specific programming, since it moves using the force of the pump, which is directed randomly.

It is an alternative solution to the electric, whose necessary investment does not convince everyone. It can be used as a complement to the manual cleaner, which can clean walls and bottom more deeply, but whose use could be much more spaced in time thanks to the regular performance of the hydraulic model. It depends, in any case, on the characteristics of the pool.

In addition, it is a more sustainable alternative (although it depends on the model) and it can last longer.

Purchase guide: what hydraulic pool cleaner to buy?

Choosing with the spotlights on the characteristics of the pool, it is not difficult to choose a hydraulic cleaner. We summarize in several points what you have to look:

The power

The cleaners are connected to the filtration system of the pool but, in order for them to work properly, they need the pump to have a minimum power, which will depend on the model. Choose the one that fits well with the power of your pump.

The type of pool

There are cleaners that only work well in removable pools and others that only do so in buried areas, as long as they do not exceed a certain length and capacity. It is an aspect that you must take into account along with the shape of the glass (rectangular, round …), although the coating material is not usually a problem for this type of cleaners.

The type of device

Whether they are pressure or propulsion, they use a type of technology that can be more or less effective (even more or less noisy), which you must also share with the characteristics of the pool.

Comprehensive/partial cleaning

Not all available options can clean bottom and walls, even fewer steps in and out to the pool. In fact, there are some that get stuck easily when encountering an obstacle, so if your glass has a lot of capacity or has them, you’d better look at other possibilities.

The Extras

There are the basic models and there are those that incorporate some extra element that allows them to make a difference, but also makes the product more expensive. We speak, for example, of systems of orientation in the pool, which allows them to have a more optimized behavior of the time.


It is evident that there are more advanced models than others, and that they will have a higher price. However adjusted your budget is, for the cheap you want to buy, you sure do not want to throw away the money.

The guarantees

To avoid throwing away money, on the other hand, you should look at the product warranty and agree with the distributor on a refund formula, in case it does not work for you.
