Hydropool sells the world’s only line of self-cleaning hot tubs. We have a patent on the self-clean process for hot tubs, which is based on how commercial pools are cleaned.

So it will come as no surprise that we are asked frequently about self-cleaning hot tubs: how they work, are they worth it, how much they are. These are all logical questions any smart consumer would want the answer to.

And we are used to explaining them! We want to make sure people understand the difference between our self-cleaning hot tubs and how traditional hot tub works. So in this article we will go through:

  • How do self-cleaning hot tubs work?
  • How do traditional hot tubs work?
  • Are self-cleaning hot tubs worth it?
  • How much is a self-cleaning hot tub?

Hopefully, when we get to the end, you’ll have a really strong sense of what a self-cleaning tub is and whether it’s right for you.



What is a self-cleaning hot tub?

Before any other question, let’s answer the core one: What is a self-cleaning hot tub? It’s an advanced cleaning system, based on the principles of commercial pools.

Commercial or public pools are much more highly regulated than hot tubs. You have to meet strict requirements when making a pool designed for the public.

Self-cleaning hot tubs have all of the elements that commercial pools have. Ay Hydropool, we adopted them initially because we began as a commercial pool company before we became focused on hot tubs. We used commercial pool elements because we knew a hot tub would work that way.

Later, we patented the process when we realized other hot tub companies were doing it differently.  

How do self-cleaning hot tubs work?

It’s easier to watch it then to explain it: Have a look here at Hydropool’s self cleaning system:

Our Signature line of hot tubs feature self-cleaning. Self-cleaning hot tubs have three aspects:

  1. A topside skimmer: Due to the properties of water, particles float on the surface or sink to the bottom. A topside skimmer removes anything floating on top.
  2. A floor vacuum: It sucks up anything that falls to the bottom, so you don’t have to clean it later.
  3. Pressurized filtration: This means your water is forced into your filter. This method ensures the cleaning system filters 100 per cent your water every 10 minutes in the hot tub.  

As mentioned earlier, this entire model comes from the world of commercial pools. For more information on this aspect, try this article.

When your view is this good, do you really want to be thinking about maintenance in your hot tub?

Aren’t all hot tubs self-cleaning?

Hot tub water filtration is designed to keep the water in the spa clean. Since all hot tubs have water filtration, does that mean that all hot tubs are self-cleaning?

To a certain extent, yes. But remember what a true self-cleaning system does is advance the cleaning process with features adopted from the world of commercial pools, which are regulated much more than hot tubs.

In the simplest terms, a self-cleaning hot tub has incredibly efficient filtration, making your hot tub easier to maintain, so you can spend your time using it rather than maintaining it. That’s the goal of our engineers who developed it.

Is a self-cleaning hot tub maintenance free?

A self-cleaning hot tub doesn’t remove all maintenance. No hot tub can do that.

Your water will still require balancing, to ensure that the ph and other levels do not get out of whack. You will still need to sanitize it with chlorine or bromine. And when you drain and fill it, we advise you cleaning it.  

But combined with Hydropool’s PureWater system, which uses ozone and UV-light to wipe out elements like bacteria before they can begin to form (that system comes standard on self-cleaning models), and you have a system that is as low of maintenance as currently be made.

How do traditional hot tubs work?

Hydropool is entirely familiar with the standard way of cleaning hot tubs. We use a form of this method for our Serenity collection as opposed to our self-cleaning Signature collection. This would be considered the standard way that hot tubs work, as opposed to how a Hydropool hot tub does.

  1. A topside skimmer is standard, but other ways of cleaning anything are limited.
  2. No floor vacuum. On some hot tubs there is sometimes a side suction element, but if it’s not on the floor it doesn’t capture what a floor vacuum does – everything that makes it to the bottom.
  3. Non-pressurized filtration, so that all of your water isn’t being processed regularly. You still have filtration, but since it isn’t forced filtration, it’s not as effective.  

Are self-cleaning hot tubs worth it?

Yes. We think so or we wouldn’t sell them. We are completely biased here though, we admit! We think it’s a system that works well. We have been in business for more than 40 years, and we have seen how successful it is for customers.

If what you’re asking is “should you buy from us,” here’s our best pitch.

How much is a self-cleaning hot tub?

Our least expensive self-cleaning option is about $13,000, with our most expensive tops out around $21,000. It’s worth noting here that while we do carry the lower-priced Serenity line, the self-cleaning models are our best-selling hot tubs.

What is a self-cleaning hot tub?

A self-cleaning hot tub is one designed with an elite sanitization system that does as much cleaning as possible for you.

Based on the principles of behind more heavily regulated commercial pools, it’s designed to minimize your maintenance costs and efforts so that you can spend your time using your hot tub instead of cleaning it.

Hydropool’s line of self-cleaning hot tubs is called the Signature line. You can find more about it here.
