Sirena or Rainbow?
You are about to spend two thousand euros or more on a vacuum cleaner and you want to know whether you are choosing the right one. This page compares the two using facts you can check yourself — not promises.
Start with the obvious: they are not opposites. Both work the same way. There is no 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.

Almost every tick is green on both sides, and rightly so: the technology is similar and the motor warranty is the same. The differences are in the last rows, and they are not technical. With Rainbow you cannot buy online and there is no price: you request a demonstration and a distributor 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 3,500 € 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 you have just read without asking anyone — and it is less than half.
Two rows that deserve an explanation
The two hoses. There are two in the Sirena box, and it is not a detail for a list: one is electrified and drives the power nozzle and the motorised accessories; the other has no electrical connections and is the one you use to pick up liquids. They are two different jobs and on the Sirena two different hoses do them. The Rainbow manual instead describes a single electrified hose, also used for wet pick-up.
Service for people who did not buy from us. In the Rainbow manual, Rexair writes that it does not protect "customers who have used unauthorised sellers or Internet channels". We do the opposite: if you own a Sirena bought years ago, from anyone and anywhere, we will still sell you the parts and still repair it in our workshop. The one thing we cannot do without an invoice or proof of purchase is replace the motor free of charge under warranty: that needs a firm date and evidence of the purchase, as it does everywhere. Everything else stays open to you.
Where Rainbow is right
The home demonstration has a real advantage, and it is only fair to say so: you watch the machine work on your own carpet, with your own dust, before you pay. We cannot offer you that, and there is no point pretending it doesn't matter.
What we can offer you is everything else in advance: the ten troubleshooting guides on this site, the videos showing how parts are replaced, the reviews collected by Trustpilot after purchase — which we do not choose — and a WhatsApp chat where you can ask anything before buying. And if the machine arrives and doesn't convince you, you have fourteen days to send it back, as European law provides.
What matters in eight years
A water vacuum lasts fifteen or twenty years. In that time the belt, the HEPA filter, the bristles, the hose insert and the motor's carbon brushes all wear out. It is not a defect: it is maintenance, and it happens with any brand.
So the 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 Rainbow is a bad machine: it is a respected brand, it has been around for decades, and the technology resembles ours. We do not claim to suck harder: you could not verify that from behind a screen.
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.
