You can leave a robot in the pool for a day or two, but you shouldn’t leave it in permanently. Constant chemical exposure, sun on the cord, and shifting water chemistry degrade seals and cables over time. For the longest life, remove it after each cleaning cycle and store it in the shade.
The short answer
Leaving your robot in the water between back-to-back cleanings is fine. Leaving it submerged 24/7 for weeks on end is not recommended by any major manufacturer, and it isn’t how the equipment is designed to be used.
Why permanent soaking shortens its life
- Chlorine and salt slowly attack seals, brushes, bearings, and cable jackets.
- A robot sitting on the floor collects the very debris it’s meant to remove and can leave marks on some finishes.
- The floating cord bakes in UV and develops the coils that lead to tangling.
- It’s a trip hazard and gets in the way of swimmers.
Best practice
Run the cycle, then pull the robot out, rinse it with fresh water (especially on salt or high-chlorine pools), and store it on its caddy in the shade. See should I remove my robot after each cycle for the full 2-minute routine.
Want to leave it in more often?
If you like the convenience of leaving it in, at least pull it after every couple of cycles and consider a model with a weekly timer so it runs on schedule and you remove it on your own time.
