Sirena or Hyla?
You are about to spend a serious amount on a vacuum cleaner and you want to know which of the two to choose. This page puts the two systems side by side using only facts you can check yourself, and it also tells you where the other one is better.
Start with what they share. Neither uses a bag: the air passes through a bath of water, the dust stays trapped in the water, and what comes out is washed air. Anyone choosing a water vacuum is choosing well. The question is which one.

There are green ticks on both sides, and one of them is theirs and not ours: the motor. Where a dash remains it is because the figure does not exist — the warranty is stated nowhere, not even in their own manual, which names it three times without ever saying how long it lasts. On Hyla there is no price and no way to buy online: you request information and an agent comes round. That is their choice and there is nothing wrong with it — but it means you only learn the price once someone is sitting in your living room.
* The 3,000 € is the order of magnitude reported to us by customers who have had a quote at home. It is not an official price and we do not present it as one: the only way to know for certain is to ask them. Ours, on the other hand, you have just read without asking anyone — and it is a little over half.
A row that deserves an explanation
The two hoses. There are two in the Sirena box: one electrified, which drives the power nozzle and the motorised accessories, and one with no electrical connections, which is the one you use to pick up liquids. It is not a duplicate: they are two different jobs. The HYLA EST manual says of its own electric hose: "Do not use it to pick up water" — and for wet cleaning it points to the NIMBUS system, which is a separate product. We are not interpreting the difference: it is written in their own safety instructions.
Where Hyla is right
It would suit us not to write this, but without it the rest would be worth nothing.
Hyla states an induction motor. An induction motor has no carbon brushes, so it does not have the part that on the Sirena, sooner or later, has to be replaced. The Sirena's motor does have them: they are made to wear out in place of the copper, and after some years of regular use they reach the end of their life. It is the most important maintenance item on the machine, and there is a whole guide on this site explaining how to notice in time.
What it costs you, concretely: the motor overhaul with new brushes and a cleaned armature is 150 €, done in the workshop, and if the armature is sound we add two years to the warranty on the motor. It is not a fault: it is scheduled maintenance, like brake pads. But you are entitled to know before you buy, not after.
Where we differ
The price is written down. Ours is on this page, VAT included and free shipping across Europe. You don't have to let anyone into your home to find it out.
The certifications. Hyla also displays international certification marks on its site, and it would be wrong to pretend otherwise. The difference is that the clean-air percentages — theirs and ours — are stated by the manufacturer, while ECARF and the Carpet and Rug Institute are two independent bodies you can look up by name and check for yourself, without going through us.
What matters in eight years
A water vacuum lasts fifteen or twenty years. In that time the belt, the filter, the bristles, the hose insert and the motor brushes all wear out. It happens with any brand.
So the real question is not which one sucks better on the day you buy it. It is who is still there on the day something breaks.
With us you see it in advance:
- every spare part is in the catalogue with its price next to it, including the cheap ones
- several parts come with a video showing how to change them yourself
- there is a real workshop for what you don't do yourself, and ten years of warranty on the motor
- there are ten troubleshooting guides, written so you check first and buy afterwards
We earn less from a customer who changes a 6.60 € belt himself than from one who buys a new machine. It is written there all the same.
What we do not claim
We do not claim that Hyla is a bad machine: it is a serious product, with technology close to ours and a motor that on one point is better built than ours. We do not claim to suck harder: you could not verify that from behind a screen, and I would distrust anyone who promises it.
What we do say is this: with us the price is written down, the parts are written down, the workshop exists. Compare that with what you get to see of the other before you sign.
