robotic pool cleaner choice

In part one of this two-part blog series, we discussed some of the primary factors you should be considering if you’re looking at a robotic cleaner for your custom swimming pool. These cleaners, which you may or may not have used in the past, make cleaning the pool a breeze compared to doing so manually, and also increase the quality and lifespan of your new pool.

At Dolphin Pools & Spas, we can help you with all the important factors involved in choosing a robotic cleaner for one of our new swimming pools. Here are a few additional things you should be thinking about as you make this important choice.

Filters and Microns

An important function of the pool cleaner is to filter out various impurities or bits of debris from the pool, which may build up over time. And within the filtration world, the important term is “microns” – referring to one-millionth of a meter, the measure used for the smallest possible items that can be filtered by a given cleaner.

When it comes to microns, the lower the number the better. You’re looking for a low-micron filter bag or basket that will allow for full disinfection and purification of your water. Don’t worry about descriptive adjectives like “fine” or “tight” – all that matters is the micron number.

Build and Durability

Make sure you do your research on the build of a given robotic cleaner, but also take the time to simply hold and examine it before purchase. You can often tell the quality of materials right then and there; if they feel cheap and easily breakable, you’re likely dealing with a subpar product. You’re looking for high-quality parts that will last for years despite moisture conditions.

Power Washing

Some robotic pool cleaners will come with power washing jets standard, while others will not. The primary use of this feature in a robotic pool cleaner is the get rid of the finer quantities of silt, sand, dirt or other similar particles – specifically from areas where the normal cleaner brushes might not be able to reach. There aren’t too many of these points in a given pool, but even just a couple of them pose a risk of impurities remaining in the water and spreading around as water moves.


If anything goes wrong with your robotic pool cleaner, especially soon after you’ve bought it while it should be operating optimally, you want to know you’re covered for your purchase. Most models should come with basic warranties – make sure you understand what yours discusses, as some will cover only repairs for the unit and others will cover a full replacement if anything happens.
