Quick Answer: The Dolphin Explorer E50 is Maytronics’ mid-to-upper-tier robotic cleaner for 2026, rated for in-ground pools up to 50 ft with full floor, wall, and waterline coverage on a 2-hour cycle. Maytronics’ own US store prices it at $1,329 on sale (regular $1,629, SKU 99996281-XP), and it ships with a 60 ft cable and MyDolphin Plus Wi-Fi app control standard — no separate non-Wi-Fi SKU, unlike the smaller Explorer E30. It sits between the E30 and the flagship Explorer E70 in Maytronics’ current lineup.
The Explorer E50 fills a real gap in Maytronics’ “Best Performance” tier: a 50 ft-rated robot priced well under the $2,099 flagship E70, with the same floor-walls-waterline coverage as the smaller E30 but enough cable and pool-size headroom for larger inground pools. Here’s what Maytronics’ own spec sheet actually says, and who it’s really built for.

By the numbers
- Pool coverage: Maytronics rates the Explorer E50 for in-ground pools up to 50 ft — a full 10 ft more than the Explorer E30’s 40 ft limit, direct from Maytronics’ own product page.
- Price: Maytronics’ US store currently lists the E50 at $1,329 on sale, down from a $1,629 regular price — roughly $230-$530 more than the E30’s $999-1,099, but $770 less than the flagship E70’s $2,099.
- Suction rate: Maytronics’ spec sheet lists 4,000 GPH — identical to the Explorer E10, E20, and E30 below it. The suction-parity pattern already documented across the cheaper Explorer tiers holds all the way up to the E50; only the pricier E70 finally breaks it with 5,000 GPH.
- Cable length: 60 ft with an anti-tangling swivel, versus the E30’s shorter standard cable — the extra length is part of what lets the E50 actually reach the walls of a 50 ft pool.
What it does well
Full waterline coverage at a real 50 ft rating. Unlike the Explorer E20 (partial wall coverage, no waterline) or even some competing mid-tier robots, the E50 scrubs floor, walls, and waterline across the full 50 ft Maytronics rates it for — matching the coverage level of the brand’s popular Nautilus CC Plus at a comparable price.
Wi-Fi app control standard, no upsell SKU. Unlike the Explorer E30, which splits into a cheaper app-free base model and a pricier Wi-Fi variant, the E50 ships with MyDolphin Plus app control built in — one SKU, one price, no guessing which version you’re buying.
Longer cable for bigger pools. The 60 ft anti-tangling swivel cable is a genuine upgrade over the E30’s shorter cable, and a practical necessity for reaching every corner of a pool pushing the 50 ft limit.
Where it falls short
- Same suction as the cheaper E30. Despite costing $230-$530 more, Maytronics’ own numbers show no suction increase over the Explorer E30 — the extra money buys pool-size headroom and cable length, not raw cleaning power.
- No NanoFilter fine-particle filtration. Like the rest of the Explorer line, the E50 uses a standard multi-layer basket rather than the NanoFilter technology on Maytronics’ pricier Quantum and Sigma models — fine debris like algae and sand passes through more easily.
- Only a 2-year warranty. The pricier flagship E70 gets a 3-year warranty from Maytronics; the E50 is capped at 2 years, the same as the smaller E30 and E20.
- No bundled caddy. The E70 ships with Maytronics’ Universal Caddy for storage and transport; the E50 does not include one, so budget separately if you want wheeled storage.
Dolphin Explorer E50 vs the alternatives
| Model | Max pool size | Cleans | Suction | Price |
|---|---|---|---|---|
| Explorer E50 | 50 ft | Floor, walls, waterline | 4,000 GPH | $1,329 sale |
| Explorer E30 | ~40 ft | Floor, walls, waterline | 4,000 GPH | ~$999-1,099 |
| Explorer E70 | 50 ft | Floor, walls, waterline | 5,000 GPH | $2,099 |
| Nautilus CC Plus | 50 ft | Floor, walls, waterline | 4,000 GPH | ~$749-849 |
That last row is the real catch: the Nautilus CC Plus covers the same 50 ft, with the same floor-walls-waterline reach and the same 4,000 GPH suction, for roughly $480-580 less than the E50’s sale price. The E50 makes the most sense if you specifically want the longer 60 ft swivel cable or prefer the Explorer line’s app and sensor set; otherwise the CC Plus is the harder value to beat at this coverage level.

Who should buy the Explorer E50
Buy it if your pool is close to the 50 ft limit, you want full waterline scrubbing with a 60 ft cable that reaches every corner, and you’d rather have Wi-Fi app control built in than choose between two separate SKUs.
Look elsewhere if your pool is under 40 ft (the Explorer E30 saves $230-530), if budget matters more than brand (the Nautilus CC Plus matches its coverage for less), or if you want Maytronics’ strongest suction and a 3-year warranty regardless of price (the Explorer E70).
The bottom line
The Dolphin Explorer E50 is a real, currently-sold Maytronics robot that closes the gap between the mid-tier Explorer E30 and the $2,099 flagship E70 — full floor-wall-waterline coverage up to 50 ft, a 60 ft cable, and Wi-Fi app control standard, all for $1,329 on sale. It doesn’t add suction over the cheaper E30, skips NanoFilter filtration, and the Nautilus CC Plus still undercuts it at the same coverage level — but for a 50 ft pool where you want the longer cable and single-SKU simplicity, it’s a solid ★★★½ pick.
