Can I Leave My Robotic Pool Cleaner in the Pool Overnight?

The answer to this question is a resounding, unequivocal “yes.”

Automatic pool cleaners are designed with waterproof, airtight casings, which prevent water from seeping into the robot and wreaking havoc on its internal workings. As such, users are more than welcome to drop their robots in the pool and forget about them overnight. In fact, some owners run one of their robot’s cleaning cycles overnight, so their pools will be swim-ready in the morning.

How Long Can It Stay in My Pool?

Another question people have regarding their robotic pool cleaner is how long they can keep it submerged. The simple answer to this question is however long you want.

For the most part, you can leave your robotic pool cleaner submerged in pool water for weeks or even months at a time. The only thing to consider is whether you want to swim with your robot and its long floating cable in the way.

However, if you’re not going to run your robot for weeks at a time, you can disconnect the cable from the robot and the remote control, leaving your robot in the water until you want to start it up again.

When Should I Fish Out the robotic pool cleaner?

Although you can leave your robotic pool cleaner in your pool for months at a time, there are certain times when it’s imperative that you fish it out of the water.

1. When shocking your pool with chlorine

Water will do nothing to affect the robotic pool cleaner’s plastic shell, but harsh pool chemicals to kill algae while shocking the pool can. So, on the night before introducing chlorine into the pool water, make sure you remove the robot and its floating cable from the pool. Wait until the next day when the sun has rendered the chlorine somewhat ineffective before dropping the robot back in your pool.

2. When emptying out the filter cartridge(s)

For obvious reasons, you will need to fish your automatic pool cleaner out of the pool to empty out the filter cartridges. You can do this by gently tugging on the floating cable until you can reach the robot. Pull the robot out of the water, detach the filter cartridge(s), then spray-clean them with an ordinary garden hose. Make sure to toss the collected debris far away from your pool so they don’t get back into your pool.

3. When the swim season is over

Robotic pool cleaners can survive normal water conditions, but when the swim season is over and the frigid months are just around the corner, you need to take the robot out of the water for maintenance and storage. Store the robot in a dry place until the following swim season.
