Quick Answer: The Dolphin Explorer E70 is Maytronics’ flagship robotic pool cleaner for 2026, priced at $2,099 direct from Maytronics (SKU 99996712-XP) with no separate sale tier. It’s rated for in-ground pools up to 50 ft with full floor, wall, and waterline coverage, a 60 ft cable, and Maytronics’ strongest listed suction rate at 5,000 GPH — though Poolbots’ independent testing measured it closer to 4,500 GPH, a real source conflict worth knowing about before you pay the premium. It ships with a bundled caddy and a 3-year warranty, both upgrades over the cheaper Explorer E50.
The Explorer E70 sits at the top of Maytronics’ “Best Performance” tier, priced $770 above the already-reviewed Explorer E50 for the same 50 ft rating and identical floor-walls-waterline coverage. Here’s what the spec sheet actually says the extra money buys — and where it doesn’t.

Dolphin Explorer E70
- Cleans the floor, walls and waterline of in-ground pools up to 50 ft with active scrubbing.
- Maytronics' strongest listed suction rate across the entire residential lineup.
- Bundled caddy and a 3-year warranty — both exclusive to this tier within the Explorer line.
- MyDolphin Plus Wi-Fi app control standard; no on-unit scheduling without the app.

By the numbers
- Price: Maytronics’ own US store lists the Explorer E70 at a flat $2,099 (SKU 99996712-XP) — $770 more than the Explorer E50’s $1,329 sale price, with no separate discounted tier.
- Suction rate: Maytronics’ spec sheet claims 5,000 GPH, the only Explorer tier to beat the 4,000 GPH ceiling shared by the E10, E20, E30, and E50 — but Poolbots’ independent hands-on review measured it closer to 4,500 GPH, a real gap between the manufacturer figure and third-party testing worth factoring in before paying the premium for suction alone.
- Warranty: 3 years, a full year longer than every other Explorer-tier robot (E10 through E50 are all capped at 2 years).
- Weight: roughly 25 lbs, heavier than the E50’s 19.2 lbs — a real tradeoff if you’re lifting it out solo after every cycle.
What it does well
Strongest suction in the Explorer line, on paper. Maytronics’ own number (5,000 GPH) is a genuine step up from the 4,000 GPH shared across every other Explorer tier — even if Poolbots’ real-world measurement of ~4,500 GPH suggests the gap over the E50 is smaller in practice than Maytronics’ spec sheet implies.
Only Explorer tier with a bundled caddy. Storage and transport caddies typically run as a separate accessory purchase on this site’s own power-supply and caddy-adjacent guides — the E70 includes one standard, a real value-add at this price point.
Longest warranty on the Explorer line. At 3 years, the E70 covers an extra 12 months over the E10 through E50, matching the warranty length of Maytronics’ pricier Premier and Sigma flagships.
Where it falls short
- No NanoFilter fine-particle filtration. Despite being the priciest Explorer model, Poolbots confirms the E70 uses standard multi-layer basket filtration — the same tier as the cheaper E10-E50 models, not the NanoFilter tech on the Quantum or Sigma.
- No leaf bag. Per Poolbots, virtually every current Dolphin robot skips a leaf bag except the Dolphin Premier — if your pool sees heavy leaf fall, that’s a real gap.
- Suction claim doesn’t fully hold up under independent testing. Maytronics’ 5,000 GPH figure is the headline reason to pay $770 more than the E50, but Poolbots’ own measurement (~4,500 GPH) narrows that gap considerably.
- App-only scheduling. Like the rest of the MyDolphin Plus-equipped Explorer tiers, there’s no on-unit control — you need the app open to schedule or start a cycle.
Dolphin Explorer E70 vs the alternatives
| Model | Max pool size | Suction | Warranty | Price |
|---|---|---|---|---|
| Explorer E70 | 50 ft | 5,000 GPH (Maytronics) / ~4,500 GPH (Poolbots) | 3 years | $2,099 |
| Explorer E50 | 50 ft | 4,000 GPH | 2 years | $1,329 sale |
| Nautilus CC Plus | 50 ft | 4,000 GPH | 1 year | ~$749-849 |
| Dolphin Sigma | Large pools | 4,500 GPH | 3 years | ~$1,499 |
The real question isn’t the E70 versus the E50 on pool size — both cover the same 50 ft — it’s whether the extra suction and the 3-year warranty are worth $770. If Poolbots’ ~4,500 GPH measurement is closer to reality, the E70’s real-world cleaning power edge over the E50 is modest, and the Dolphin Sigma — a large-pool flagship with its own 3-year warranty, triple motor, and 3-axis gyroscope navigation at roughly $1,499 — may be the harder competitor to beat at a similar price tier. For a smaller budget at the same 50 ft coverage, see the full Dolphin Explorer E50 review or the best Dolphin pool cleaner guide for the complete lineup.
Who should buy the Explorer E70
Buy it if you want Maytronics’ longest warranty on an Explorer-tier robot, a bundled caddy without an extra purchase, and you’re willing to pay a premium for the manufacturer’s highest suction claim even if independent testing narrows that gap somewhat.
Look elsewhere if budget matters more than the warranty bump (the Explorer E50 covers the same 50 ft for $770 less), if you want proven large-pool navigation smarts at a comparable price (the Dolphin Sigma’s gyroscope and SmartNav system), or if NanoFilter fine-particle filtration matters more to you than suction GPH (neither Explorer tier offers it).
The bottom line
The Dolphin Explorer E70 is Maytronics’ real flagship — a $2,099, 50 ft-rated robot with the line’s strongest claimed suction, a bundled caddy, and a 3-year warranty, all genuine upgrades over the cheaper Explorer E50. But Poolbots’ independent testing measuring suction closer to 4,500 GPH than Maytronics’ claimed 5,000 GPH means the suction gap over the E50 is smaller in practice, and the similarly-priced Dolphin Sigma brings large-pool navigation tech the Explorer line doesn’t have. For buyers who specifically want the longest Explorer-tier warranty and an included caddy, it’s a solid ★★★★ pick — just go in knowing the suction claim is the one number worth taking with a grain of salt.
