It is tempting to just leave the robot in the water, and occasionally that is fine — but making it a habit will cost you.
Short-Term Is Okay
Leaving your cleaner in the pool for a day or two, or between back-to-back cycles, will not hurt it. Many owners with a weekly timer leave it in during peak season for convenience.
Why Permanent Storage in the Pool Is a Bad Idea
Pool water is a harsh environment for electronics and rubber. Leaving a robot submerged 24/7 means constant exposure to:
- Chlorine and salt, which degrade seals, brushes, and the cord over time
- UV and heat, which make plastics brittle and can shorten motor life
- Debris and chemistry swings that settle into the housing
It also keeps the robot in the way of swimmers and can concentrate chemicals against it if you shock the pool. See can I swim while the pool robot is running and whether you should remove it after each cycle.
The Best Practice
Run the cycle, then lift the robot out, rinse the filter, and store it on its caddy in the shade. This simple routine can add years to its life. Robots built with quality seals and materials — like the Dolphin Sigma — hold up best; see how long you can expect one to last in how long does a pool robot last.
