Lifespan varies widely by build quality and care, but there is a clear range and clear ways to stretch it.
Typical Lifespan
- Budget robots: often 3 to 5 years
- Premium corded robots: commonly 5 to 8 years or more with good care
The difference comes down to motor quality, seal durability, and materials. A cheaper machine simply has more that wears out sooner, which factors into whether expensive pool robots are worth it.
What Shortens a Robot's Life
- Leaving it in the pool full-time — constant chemical, salt, and UV exposure, covered in can you leave your pool robot in the pool
- Neglecting the filter, forcing the motor to strain
- Sun and heat on the power supply and plastics
- Running a jammed or debris-clogged unit
How to Make It Last
Remove and rinse it after each cycle, keep the filter clean, store it shaded on its caddy, and replace wear items like brushes and tracks from our parts page before they cause damage. A well-built model like the Dolphin Sigma rewards this care with many seasons of service. See our best robotic pool cleaners guide for durable picks.
