A Quick Guide on How Self-Cleaning Hot Tub and Swim Spa Technology Works

Self-cleaning hot tubs and swim spas allow you to spend less time on maintenance and spend more time enjoying your spa, but you might be wondering what’s involved in the process. Below, we’ll share an overview of how the technology works to keep the water in your spa crystal clear. Here’s what you should know!

The Basics of the Self-Cleaning Feature

You’re probably wondering how hot tubs and swim spas can be self-cleaning. Well, the process relies on the filtration system. The system is designed to circulate the water so that it’s constantly being filtered and cleaned. All hot tubs and swim spas that have filters technically clean themselves. However, those that are truly self-cleaning are the ones that have superior filtration systems with more advanced technology. You can also get in touch with your local spa dealer for more information about the different spa filter options available. It’s important to note that ‘self-cleaning’ doesn’t mean zero maintenance, as you will still have to stay on top of these tasks to keep your spa in the best condition:
  • Test the chemical balance of the water
  • Rinse the filters and replace as needed
  • Drain and refill the water
However, with that said, when you have a self-cleaning hot tub or swim spa, you can do these tasks a lot less often. A key benefit of this feature is that you can enjoy your spa without having to worry about maintenance as much.

What’s Involved in the Self-Cleaning Process?

If you’re curious about the specifics of the self-cleaning process, here’s a breakdown of the main elements and general steps involved:

1.Surface Filtration

The surface of the water can collect particles and debris even if you don’t use your hot tub and swim spa often. The self-cleaning system tracks down all the floating particles so that the filtration jets can push them toward the high-flow skimmer and pre-filter. This helps keep the water’s surface clean.

2.Complete Surface Cleaning

After the initial filtration, the high-flow skimmer and the pre-filter remove the remaining particles as well as oils and other similar substances. They also work together to keep the pump and the heater from getting clogged with debris.

3.Deep Floor Vacuum

Sometimes, there are heavier particles that the pre-filter can’t remove and they end up sinking to the bottom. The floor vacuum of a self-cleaning spa sucks them all up and pushes them to the pressurized filter. Another maintenance task that the vacuum helps with is the distribution of sanitizers. This further prevents any dirt or grit from building up.

4.Pressurized Micro-Filtration

To ensure that the water remains clean and clear, the pressurized filter takes care of all the fine particles that are too small for the other components to get rid of. It also allows clean water to re-enter through the jets. Self-cleaning spas with sophisticated features include more steps in the filtration process aside from the ones mentioned above. For example, Hydropool hot tubs and swim spas also have a purification process after clean water re-enters the filters. At that point, Ozone and UV light eliminate 99% of contaminants. When all that’s done, a Self-Clean indicator lets you know that the self-cleaning function has been successful and your spa is ready for use.

What Makes Self-Cleaning Spas Worth It?

Wondering if you should go with a self-cleaning model for your hot tub or swim spa? Aside from spending less time on maintenance, here are some of the other advantages you can expect:

Lower utility costs

Because the water is constantly being filtered and cleaned, your spa won’t need to be drained as often. This saves you money on energy and water bills.

No need to use as many chemicals

With self-cleaning spas, you don’t need to use a lot of chemicals for the water to stay sanitized.

Repairs are less frequent

Since the water is constantly circulating, it’s less likely for parts to get clogged or damaged. This translates to fewer repairs in the long run.

More time to enjoy

You won’t be spending as much time on cleaning and maintenance, which means more time to enjoy your backyard oasis to the fullest. With a self-cleaning hot tub or swim spa, you can make the most of your spa experience without needing to spend so much time on maintenance. And depending on the model you choose you may even see cost savings over time. Whether you have a small family or a large group of friends, self-cleaning spas are perfect for anyone who wants to enjoy the benefits of a spa without the hassle of constant upkeep.
