How Long Do Robotic Pool Cleaners Last?
A well-kept robot typically lasts about 5 years, often longer. Here's what wears out first, how warranties compare and how to make yours last.
In short
Expect around 5 years from a well-maintained robot, with some lasting 7 or more and others failing sooner. Batteries (cordless) and cables (corded) are the usual weak points; brushes, tracks and filters are wear parts you replace.
Pool robots aren't forever, but a well-kept one lasts years. Makers rarely publish lifespans, so these figures come from a Dolphin retailer, a pool dealer and owner discussions.
Typical lifespan
- About 5 years is a common owner experience, according to a long-running Trouble Free Pool thread, with some robots failing earlier and some lasting much longer.
- A Dolphin retailer's FAQ says 5 to 7 years with proper care.
- A pool dealer puts premium robots at 5 to 8 years or more, and notes that daily use shortens that compared with cleaning once or twice a week.
What wears out
| Part | Why it fails | What to do |
|---|---|---|
| Battery (cordless) | Lithium-ion loses capacity with age and charging, faster when stored empty or hot | Store at about 60% charge indoors in the off-season |
| Cable (corded) | Twists and wear over the years | Unwind it, store it loosely, replace if damaged |
| Brushes and tracks | Rubber wears smooth and loses grip | Replace when worn; robots stop climbing otherwise |
| Filters | Mesh clogs and tears | Rinse after every cycle; replace when damaged |
Warranties as a clue
Warranty length hints at what a maker expects. From the makers' published terms: Beatbot gives 2 years on the Sora 10 and 30 and 3 years on the Sora 70 and AquaSense 2; Dolphin 2 years on the Nautilus CC Plus and E10; WYBOT 1 to 2 years depending on the model; Aiper 2 years on the Scuba V3.
How to make a robot last
- Take it out after every cycle. Beatbot advises against leaving robots in the pool all the time.
- Rinse the filter after each use.
- Keep water balanced: harsh chemistry ages seals and brushes.
- Store it indoors in the off-season, dry and out of the sun.
- Replace wear parts early, before they damage something else.
