The Dolphin-versus-Aiper question is really the corded-versus-cordless question with two specific brands attached. Dolphin is the established corded name with the deepest service network; Aiper is the cordless-value upstart that made losing the cable affordable. Here's how they actually differ, and which one fits your pool. This is a research-based comparison, not a hands-on test.
Quick answer
| Dolphin | Aiper | |
|---|---|---|
| Power | Corded, mains-fed | Cordless battery |
| Runtime | Unlimited per cycle | Capped per charge (~90–210 min) |
| In-pool cable | Yes — anti-tangle swivel | None |
| Service network | Largest, decades of dealers | Younger |
| Long-term wear | Very little | Battery replacement over time |
| Price | Value to premium | Mid-range, discounted often |
| Best for | Large pools, set-and-forget | Cord-haters, freeform pools |
Where Dolphin wins
Dolphin's corded design is its strength. Power stays consistent because it draws from the wall, the robot never runs out mid-cycle, and there's no charging step in your routine — you schedule it and forget it. That reliability matters most on a large pool, where a battery might die before the job's done. The model range is deep and the filter systems are mature, from the leaf-bag Dolphin Premier to the fine-filter Dolphin Quantum. And Maytronics' dealer network means parts and service are easy to get for years. The one real cost is the cable, which good models tame with an anti-tangle swivel.
Where Aiper wins
Aiper deletes the single most-hated part of pool cleaning: fishing a floating cable out from around the ladder. The Aiper Scuba S1 brings wall and waterline cleaning with structured navigation at a mid-range price, and it's light enough to drop in and lift out easily — a bigger deal in a freeform pool where cords snag on every corner. Aiper discounts often, which stretches the value further. The trades are a battery you'll eventually replace, runtime capped per charge, and a support network that's younger than Maytronics'.
How to choose
Go Dolphin if your pool is large, if you'd rather never think about charging, or if a deep service network gives you peace of mind. Go Aiper if the cable is your main complaint, your pool is freeform, or you want cordless convenience without paying flagship money. There's no wrong answer — just the annoyance you'd rather live with, cord or charge. Our Pool Robot Finder sorts it from a few quick questions about your pool.
Frequently asked questions
Is Dolphin or Aiper better?
Dolphin is usually the safer pick for buyers who want corded reliability, strong dealer support, and fewer charging habits. Aiper is more attractive for buyers who specifically want cordless convenience and are comfortable checking runtime, charge time, and battery-related tradeoffs.
Is Aiper better because it is cordless?
Cordless is more convenient, but it is not automatically better. Runtime, charge time, retrieval, battery life, and cleaning coverage matter more than the absence of a cord.
Do Dolphin pool cleaners have better warranties than Aiper?
Warranty depends on the exact model and seller. Maytronics says Dolphin warranties typically vary by model, often ranging from 24 to 36 months, while Aiper publishes its own refund and warranty terms. Always confirm the exact model before buying.
Which is better for a large pool, Dolphin or Aiper?
Many large-pool owners will prefer a strong corded Dolphin because it does not rely on a battery cycle. Some higher-end cordless Aiper models may fit certain large pools, but runtime and cleaning coverage must be checked carefully.
Should I buy Dolphin or Aiper from Amazon?
Amazon can be convenient, but check the actual seller, warranty path, return terms, model number, and whether the listing is from an authorized or trusted source.
