Beatbot vs Dolphin Pool Cleaner: Which Is Better?
Last updated: 29 July 2026 · Reviewed by the Poolbot UK product team
Beatbot beats Dolphin on two fronts that matter day to day: every Beatbot model is fully cordless, and Beatbot's AquaSense range adds AI-guided navigation and ClearWater™ water clarification that Dolphin doesn't offer. Dolphin (Maytronics) is one of the best-known names in robotic pool cleaners — most of their standard range, including the E10, E20, E30, M250, M400 and S300, are corded, plugging into a standard outlet with a cable trailing into the pool. Dolphin does offer a cordless Liberty range in the UK (Liberty 300/400/600), but it doesn't match Beatbot's AI navigation or water clarification features. Beatbot's range, from the Sora 30 to the AquaSense X, has no cable to manage at all. Beatbot also backs every model with a UK-based warranty (2 years on Sora 30, 3 years on Sora 70 and the AquaSense range, with full machine replacement) through Poolbot, its UK-authorised retailer.

Why buyers choose Beatbot over Dolphin
- No cable to manage. Every Beatbot model is fully cordless — drop it in and walk away. Most Dolphin models (E10, E20, E30) plug into a standard outlet with a cable running into the pool.
- Water clarification built in. The AquaSense 2 Pro and Ultra add ClearWater™ natural water clarification alongside physical cleaning — Dolphin's range is cleaning-only.
- UK-authorised retailer. Poolbot is the UK's authorised Beatbot retailer, with UK-based support and warranty backing — no need to import or deal with a US/EU-only warranty.

Beatbot vs Dolphin E10
The Dolphin E10 is Maytronics' entry-level corded cleaner — floor-cleaning only, with a 12m cable and a 1.5-hour cycle time, built for pools up to 8m in length. It's a budget option, not a like-for-like match for Beatbot's cordless AquaSense range, which cleans floor, walls and waterline in a single autonomous run.
| Beatbot AquaSense 2 Ultra | Dolphin E10 | |
|---|---|---|
| Power | Cordless | Corded (12m cable) |
| Cleans | Surface, waterline, floor, walls + water clarification | Floor only |
| Cycle time | Up to 10 hours surface cleaning | 1.5 hours per cycle |
| Pool size | Suitable for large residential pools | Pools up to 8m in length |
| Navigation / AI | HybridSense™, 27+ sensors, 4K AI camera, full 3D mapping | Not published |
| Warranty | 3 years, full machine replacement, includes battery | Not published — check with retailer |
The E10 is worth considering only if you have a small pool and just need basic floor cleaning on a budget. For full floor, wall and waterline coverage with no cable, the AquaSense 2 Ultra is built for a different job entirely.
FAQs
Is Beatbot better than Dolphin?
Beatbot's key advantage over Dolphin is that the entire range is cordless, while most Dolphin models are corded. Beatbot's AquaSense range also adds AI-guided navigation and water clarification, which Dolphin doesn't offer.
Is Dolphin cordless or corded?
Most of Dolphin's standard range (E10, E20, E30, M250, M400, S300) is corded — they plug into a standard outlet. Dolphin does offer a cordless option in the UK, the Liberty range (Liberty 300/400/600), though it doesn't include Beatbot's AI navigation or built-in water clarification.
What warranty does Beatbot offer vs Dolphin?
Beatbot offers 2 years (Sora 30) or 3 years (Sora 70, AquaSense range) with full machine replacement, backed by UK-based support from Poolbot.
Can I leave my Dolphin or Beatbot pool robot in the pool all the time?
Dolphin's corded models like the E30 can technically stay connected in the pool since they run on mains power rather than battery, but most manufacturers recommend removing any cleaner between uses to protect its motor and electronics long-term. Beatbot's cordless design means it comes out to recharge after every clean by default — it's never left in the pool permanently.
Does the Dolphin E10 clean walls and waterline?
No — the Dolphin E10 is a floor-only cleaner. For floor, wall and waterline coverage in one run, Beatbot's AquaSense range is the closer match.
What size pool is the Dolphin E10 built for?
Maytronics markets the E10 for pools up to 8 metres in length — smaller than what Beatbot's AquaSense range is designed for.
How does Sora 30 compare to the Dolphin M250 on price?
They're nearly identical — Sora 30 is £998 and the Dolphin M250 is £995. The difference comes down to cable (Sora 30 is cordless, the M250 has an 18m cable), waterline cleaning (Sora 30 includes it, the M250 doesn't), and warranty (2 years vs 1 year).
