How Long Do Robotic Pool Cleaners Last? (Brand-by-Brand Breakdown)
A quality robot lasts 5–8 years with the right care. Here is what determines lifespan.
Average Lifespan by Brand
Based on owner reports, repair forums, and our own multi-year testing, here is the realistic lifespan you should expect:
| Brand / Model Tier | Typical Lifespan | Warranty | Parts Available? |
|---|---|---|---|
| Dolphin (all models) | 5–8 years | 2 years | ✓ Excellent |
| Polaris (F-series) | 5–7 years | 3 years | ✓ Good |
| Hayward AquaVac | 5–7 years | 2 years | ✓ Excellent |
| AIPER / Budget Cordless | 2–4 years | 1 year | Limited |
| Budget generic brands | 1–3 years | 1 year | ✗ Poor |
What Determines How Long Your Robot Lasts
Three factors dominate:
1. How you store it. The single biggest factor. A robot stored properly (out of UV, drained for winter, on a caddy) can easily outlast its warranty by 3–4 years. One left in the pool all summer might not make it two seasons.
2. Filter maintenance. A clogged filter forces the pump motor to work harder. Run the robot with a dirty filter repeatedly and you'll burn out the motor in 2–3 seasons instead of 6–8.
3. Pool chemistry. Chronically low pH (acidic water) degrades rubber seals and plastics faster. Keep your pH between 7.2 and 7.6 for maximum equipment longevity.
Signs It Is Time to Replace (Not Repair)
- The pump motor is dead and repair costs exceed 50% of replacement cost
- Drive tracks are cracked and replacement parts are no longer available
- The unit repeatedly loses navigation (erratic movement) despite software resets
- Cord damage beyond the replaceable section
Brushes, filter cartridges, impellers, and most electronic boards are user-replaceable. The motor and chassis are the expensive parts — once those go, compare repair quotes to new unit pricing before deciding.
