Do Self-Cleaning Hots Tubs Really Work?

Do Self-Cleaning Hots Tubs Really Work?

If you’re familiar with hot tubs and spas, you might have heard about self-cleaning hot tubs. You might think anything that cleans or takes care of itself is too good to be true. And, well, you’d be correct on some levels.  The truth is that self-cleaning hot tubs still require some regular maintenance.


Can you imagine if your home magically cleaned itself? Yes, robot vacuum cleaners do exist. But they bump into walls and get stuck on carpets. Those little guys require some assistance, and so do self-cleaning hot tubs. But they’re worth it if you consider the time and money you’ll save on manual clean-up and chemicals.


Self-Cleaning Hot Tubs Have More Efficient Filtration Systems

The thing about self-cleaning hot tubs is that they have exclusive technology that significantly improves the efficiency of the filtration process. The system filters all the water every 15 minutes so that you can feel safe and squeaky clean.


Here’s how the filtration system works:

  1. During the cycle, the jets send all surface dirt and debris towards the skimmer and pre-filter basket.
  2. The floor vacuum extracts directly from the bottom without needing to manually.
  3. The dirt and debris get pumped through the pressurized filter. The pressurized micro-filtration increases efficiency, resulting in extended cleaning cycles.

Why Traditional Filtration Systems Fall Behind

Traditional filtration systems rely on suction-side filtration, where a skimmer is installed on one of the side walls at the water line. The pump pulls water into the skimmer, where debris gets trapped inside the filter basket. Underneath the filter basket is a micro filter that helps to keep the water clean. These filtration cycles run anywhere from 4-24 hours per day, depending on their efficiency.


The disadvantage to traditional filtration systems is efficiency since only the water that goes through the skimmer is filtered. This means the whole filtration cycle can take a long time to filter all the water in the hot tub. Another disadvantage is that heavier debris will fall to the bottom of the hot tub since only the surface water is being skimmed.

Self-Cleaning Hot Tubs Cut Back on Chemicals

Self-cleaning hot tubs reduce the need for chemicals because of their efficient filtration systems. Not only will this save you money, but you won’t have to drain and refill your hot tub frequently. Hot tubs must be drained when too many dissolved solids are introduced into the water.


Total Dissolved Solids (TDS) are the sum of all the dissolved things in any given body of water. Every time you add anything to the water, you increase its TDS. This includes sanitizing and pH adjusting chemicals, algaecides, airborne pollutants, bather waste, and all organic compounds.  

Self-Cleaning Hot Tubs are Equipped with Indicators

The Worry-Free Indicator on self-cleaning hot tubs lets you know that the self-cleaning mode is working. The indicator lets you know that the exchange systems are active, reassuring you with the safe water guarantee.


There are limits to self-cleaning hot tubs; they won’t pour the drinks for you. Here are some of the manageable maintenance tasks you’ll still have to perform:


  • Rinse and replace filters
  • Drain and refill water
  • Test pH levels
  • Manually clean surfaces
  • Remove large debris
