Robotic Pool Cleaners and Customer Expectations

As a pioneer in Sydney’s Robotic Pool Cleaner service industry, Sydney Pool Robotics stands as a trailblazer in the transformative wave sweeping across the pool maintenance sector. A decade ago, the sight of a Robotic Pool Cleaner in a backyard was a rarity, as the majority of pools relied on traditional cleaning methods such as the classic Kreepy Krauly suction cleaner or the Polaris and Jetvac pressure cleaners.

In today’s landscape, the once-prevalent traditional pool cleaners have fallen out of favour, making way for the ascendancy of the Robotic Pool Cleaner as the undisputed ruler of pool maintenance.

Nevertheless, the transition comes with a shift in dynamics. Unlike the straightforward, low-cost nature of the old-fashioned pool cleaners, Robotic Pool Cleaners represent a more sophisticated breed of electronic devices that demand a level of care far beyond their predecessors. In times gone by, a Kreepy Krauly could be purchased for under $1000, effortlessly installed into the pool, and then essentially forgotten about. It would dutifully navigate the pool for hours each day, gathering leaves and debris with a certain clumsiness, only necessitating attention when its parts wore down to dust. Replacement spares were a minimal expense, typically costing under $100, allowing pool owners to swiftly resume their pool maintenance routine.

Fast forward to the present, and the landscape has shifted dramatically. Robotic Pool Cleaners, while offering unparalleled efficiency and capabilities, come at a higher price point due to their advanced technology. The days of a pool cleaner being a set-and-forget investment are a thing of the past. These electronic marvels require a more conscientious approach to maintenance and care, necessitating a departure from the ease of the traditional pool cleaning era.

Optimising the Performance and Longevity of Your Robotic Pool Cleaner

One recurring concern among owners of Robotic Pool Cleaners is the expectation that these devices can be left in the pool continuously, operating daily. Disappointment arises when, despite the initial investment, the expensive Robotic Pool Cleaner exhibits signs of wear and lasts only three years. It’s crucial to understand that this expectation is a carryover from outdated practices, as Robotic Pool Cleaners are not designed for continuous, daily operation.

So, how can you ensure that your Robotic Pool Cleaner remains efficient and lasts for an extended period? This guide outlines three key rules often overlooked during the purchase of a Robotic Pool Cleaner that are essential for promoting the longevity of the unit.

Strategic Use Patterns

Robotic Pool Cleaners, being intricate mechanical devices, share similarities with automobiles in terms of wear and tear. The more these devices are in use, the faster their components degrade. Drawing an analogy to car maintenance, consider that if you accumulate 100,000 kilometers on your car in a year, it would need servicing ten times based on the typical 10,000 km service schedule. Similarly, a Robotic Pool Cleaner benefits from less frequent servicing when used less frequently.

Quality Robotic Pool Cleaners log operational information onboard, tracking cycles, hours of operation, and faults such as being out of water, part cycles, and motor overloads. Historical data analysis reveals that an average Robotic Pool Cleaner requires a running gear check after 250 runs and electrical component servicing after 500 runs. While these are average figures, it’s important to note exceptions to the norm. We recommend using Robotic Pool Cleaners twice a week whenever possible, accumulating around 100 runs annually. This approach necessitates servicing every second year, allowing the unit to operate smoothly for at least five years before major intervention is required. Conversely, daily operation mandates annual servicing, with a likelihood of major failures within two to three years.

This critical information is often overlooked during the purchase of a Robotic Pool Cleaner but is indispensable for managing customer expectations. Running your robot every day is not a sustainable practice for its longevity.

Water Chemistry

Robotic Pool Cleaners operate in arguably the harshest domestic environment, exposed to water, sunlight, and chemicals designed to break down and destroy foreign substances. Following the guidelines outlined in your Robotic Pool Cleaner’s manual, maintaining the ideal water balance is imperative:

  • Chlorine levels should not exceed 5ppm
  • pH levels between 7.2 and 7.8
  • Salt levels should not surpass 5000ppm

This balance is crucial because the components of your Robotic Pool Cleaner are designed to tolerate it. Deviations from this range result in rapid degradation of components, particularly in high chlorine environments. Rubber tracks and seals degrade swiftly in such conditions, and once the seal fails on the motor block, the inevitability of your robot’s failure becomes apparent.

Regular Servicing

Similar to automobiles and other mechanical devices, Robotic Pool Cleaners require routine servicing. Components such as foam rollers, climbing rings, and brushes are vital to the robot’s operation. These are wearing parts, and once worn, your robot may struggle to perform tasks such as climbing walls. Continued attempts to climb under stress can put excessive pressure on the motor, shortening its lifespan.

At Sydney Pool Robotics, we strongly recommend an annual check for all robots. Conducting this check during the winter ensures that, barring any unforeseen events, your robot will dutifully maintain your pool’s cleanliness throughout the swimming season.

By adhering to these guidelines, you not only optimize the performance of your Robotic Pool Cleaner but also extend its operational lifespan, making your investment in cutting-edge pool maintenance technology truly worthwhile.

Robotic Pool Cleaners and Water Chemistry

At Sydney Pool Robotics we often see Robotic Pool Cleaners that have been subject to improper water chemistry. Many robot owners feel ripped off when their robot does not last as long as they had hoped, however in many instances user error is the reason why the robot has failed. And it’s not necessarily the owners fault, too often the proper way to use and care for a robot is not relayed to the client by the retailer.

Within your Robotic Pool Cleaner owners manual, which we know most people do not read, you’d notice that it states the ideal water balance for your robot is as follows:

Chlorine no higher that 4ppm
pH Between 7.0 and 7.8ppm
Maximum salt level 5000ppm.

When your robot is subject to water chemistry outside of these ranges, rapid and permanent damage can be caused to the electrical and mechanical components. The leading cause of premature failure of robotic pool cleaners is high chlorine. High chlorine bleaches your robots exterior, decays the cable and tracks, and worse of all, causes the failure of seals on the motor. Once these seals have failed, water enters the motor unit and destroys the electrical components.

We typically see a spike in High Chlorine related failures around July each year and the reason for this is likely the reduced chlorine demand from your pool. Throughout summer, your saltwater chlorinator is generating chlorine all day just to keep up with the demand from warm water and high bather loads, but as the water cools the demand for this chlorine drops. However, no one tells your saltwater chlorinator this, and it continues generating chlorine regardless, gradually causing the chlorine level in your pool to reach dangerous levels. This high chlorine will then cause expensive damage not only to your Robotic Pool Cleaner, but to components of your filtration system.

High chlorine is easily identifiable. Keep an eye out for these tell tale signs:

  • Strong odour of chlorine when removing the robot from the pool.
  • Bleached white debris within the robot.
  • Decaying cable and tracks.

If you detect any of these issues, remove your robot from the pool and wash it down with fresh water. Do not return the robot to the pool until the water balance has been addressed.

How to Avoid Chemical Damage

The best way to avoid chemical damage to your Robotic Pool Cleaner is to know your pool. Purchase some test strips that allow you to regularly test your water at home, this will help you get an understanding of chlorine demand in your pool. You’ll notice variations from season to season, and even week to week as the weather changes. Adjust your chlorinators output as required as per the test results, if the chlorine level is low, increase the output. If the chlorine level is high, reduce the output.

Ideally, remove your robot from the pool when not in use, put it in to clean the pool and remove it when it is finished. We know this isn’t always feasible, but it is best practice and will extend the life of your robot.

Lastly, have your robot serviced annually. Your Robotic Pool Cleaner is a sophisticated piece of electrical equipment that operates underwater in harsh conditions. Annual servicing is a must if you are going to keep your robot in good working order. Even during the warranty period a quick trip to a service center will allow trained technicians to look over your robot and they may be able to resolve minor issues that could have become major expenses.
