When Should You Replace Your Robot Pool Cleaner?

It’s important to know when to replace your robot pool cleaner. A worn-out or broken robot pool cleaner can do more harm than good, so staying on top of things is crucial.

You should ideally replace your robot pool cleaner every three to five years. However, if you take good care of your robot pool cleaner and don’t use it too often, it could last up to seven years. However, if you use it frequently or don’t maintain it well, you may need to replace it sooner. 

This article will further discuss the signs that indicate it’s time for a replacement, as well as how to prolong the life of your robot pool cleaner. Keep reading to learn more!

You should change your cleaner every three to five years.

Signs That Indicate a Replacement

Here are a few signs that it might be time to replace your robot pool cleaner:

Note – If your device is within the warranty period or at least less than three years old, then consider fixing the problem first instead of buying a new one.

It’s Not Cleaning As Well as It Used To

Over time, your pool cleaner will start to lose its suction power. This means it won’t be able to pick up as much dirt and debris as it used to.

If you notice that your swimming pool isn’t as clean as it used to be, even after running your cleaner, it’s probably time for a new one. A new pool robot will help keep your pool looking its best and save you time and effort in the long run.

It’s Starting To Make Strange Noises

Though they are built to last, pool robots will eventually wear out. When this happens, they can start to make strange noises. All pool cleaners will make some noise, but if you notice that your cleaner is starting to make strange or unfamiliar noises, this is a sign that something is wrong. 

It could be that the motor is going out, or something else is wrong, like a broken suction valve. In many cases, unusual noises indicate a bigger problem that will only get worse (and louder) with time. If your robotic pool cleaner has started making strange noises, it’s best to err on caution and replace it as soon as possible.

It’s Leaving Streaks or Spots on the Pool Floor Or Debris in the Pool

If your pool cleaner isn’t picking up all of the dirt and debris from the floor of your pool, then you’ll start to notice streaks or spots where the dirt has been left behind. This is usually a sign that the brushes or scrubber are worn out and must be replaced. 

Additionally, one of the most frustrating things about owning an older pool cleaner is when it starts leaving debris behind in the pool instead of sucking it up into the bag or canister. If this starts happening, then it’s time for a replacement. 

The Motor Is Off

If your pool cleaner’s motor stops working or is getting overheated quite often, you’ll need to replace it. This is not something that can be repaired that easily. Furthermore, even if you can find someone to repair or replace the motor, doing so will likely be expensive. Therefore, buying a new one is really your only option. 

It Is Getting Stuck More Often and Needs Help

If your pool robot is getting stuck more often and needs help from a human to finish the job, it’s time to replace it. Pool robots are designed to make cleaning your pool an effortless endeavor, so if yours isn’t doing its job properly, what’s the point of keeping it around? It’s likely time for an upgrade. 

It’s Been More Than Three Years Since You Purchased It

As with any appliance, robotic pool cleaners have a lifespan—usually around three to five years. Of course, this varies depending on how often you use your machine and how well you take care of it. But in general, three to five years is a good rule of thumb.

How To Prolong the Life of Your Pool Cleaner

You can do a few things to prolong your pool cleaner’s life and make it last longer.

  • First, be sure to empty the canister or bag after each use. This will prevent dirt and debris from building up and damaging the cleaner.
  • Ensure to clean the filters regularly. Over time, they can become clogged with dirt and debris, reducing your cleaner’s suction power. You can help extend your pool cleaner’s life by cleaning the filters regularly.
  • Third, inspect the brushes and scrubbers on the bottom of the cleaner every few months. If they are damaged, be sure to replace them.
  • If the power cord is damaged, it will not provide enough power to the motor, and the motor will not be able to start. You can check all these things by opening your pool robot and inspecting each part.

If you find that any of these parts are damaged, you will need to replace them before your pool robot’s motor will work again. By taking good care of your pool cleaner, you can help it last for many years.

Having an Algae-Free Pool Is Important

Having an algae-free pool is so important, not just for aesthetic reasons but also for the smooth functioning of your pool robot.

Algae can quickly build up on the surface of your pool and clog up your robot’s filters, making it less effective at cleaning your pool and requiring more maintenance in the long run. It can also cause pool robots to slip and flip over when climbing. 

This can cause the motor to get overheated when exposed to air and can damage your pool robot’s internal components. So, give your pool a good weekly cleanse with an algaecide to avoid any issues.

Things To Keep in Mind When Shopping for a New Pool Robot

There are a few things you should keep in mind when shopping for a new pool robot.

  • Think about the overall size of your pool. You’ll need a big enough bot to cover your pool’s entire surface area but not so large that it’s difficult to maneuver.
  • Second, consider the type of debris you need to remove from your pool. Some robots can handle leaves and twigs better, while others can remove dirt and grime more effectively.
  • Finally, think about your budget. You can find a pool robot to fit any budget, so don’t be afraid to shop around until you find the perfect one for you.

Robotic pool cleaners are a great way to clean your pool with minimal effort. However, like any other appliance, they don’t last forever—so knowing when to replace yours is important. If your machine isn’t performing as well as it used to or if it starts making strange noises, those are both signs that it’s time for a replacement.
