Quick Answer: The Dolphin Nautilus Titan is a $1,599 in-ground robotic pool cleaner from Maytronics, rated for pools up to 50 ft with full floor, wall, and waterline coverage and a claimed 5,000 GPH suction rate. Maytronics’ own store lists it with just a 1-year warranty — and independent reviewer Pool Nerd gave it a “Disapproved” hard-pass verdict, calling that warranty “the shortest coverage of any Dolphin I’d recommend at this price” despite praising its actual cleaning performance.
The Titan sits in Maytronics’ “Best Seller” tier at a price that puts it within $500 of the flagship Explorer E70 — but the spec sheet and a hands-on review both point to the same gap: strong cleaning, weak backing.

Dolphin Nautilus Titan
- Cleans the floor, walls and waterline of in-ground pools up to 50 ft.

- MyDolphin Plus Wi-Fi app with weekly scheduling and automation mode.
- Only a 1-year warranty — the shortest on any Dolphin flagship this site has reviewed.

By the numbers
- Price: Maytronics’ own US store lists the Nautilus Titan at $1,599 (SKU 99996544-PC), in stock direct from the manufacturer.
- Warranty: Just 1 year — per Pool Nerd’s review, that’s shorter than the cheaper Dolphin Cayman and Dolphin Escape (both 2 years) and shorter than the pricier Quantum Pro, Premier, and Sigma (2-3 years).
- Owner reviews: 3.4 out of 5 stars from 19 reviews on Maytronics’ own product page, with 82% saying they’d recommend it.
- Suction rate: Maytronics claims 5,000 GPH — identical to the flagship Explorer E70’s listed figure — though Pool Nerd’s review only describes suction qualitatively (“strong in my testing”) rather than measuring it independently, so unlike the E70 (where Poolbots measured a real ~4,500 GPH gap against the claim), there’s no third-party number to confirm or dispute the Titan’s spec sheet.
What it does well
Genuinely strong cleaning performance. Pool Nerd’s hands-on testing found the Titan pulled in leaves, dirt, and fine debris effectively and held its grip climbing walls — the reviewer’s complaint isn’t about how well it cleans.
Full floor-wall-waterline coverage at 50 ft. Matches the coverage of this site’s other 50 ft-rated flagships (Explorer E50, Explorer E70) without requiring the $2,099 Explorer E70 price.
Weekly scheduling and automation via the MyDolphin Plus app, the same app ecosystem used across most of Maytronics’ current lineup, so switching between Dolphin models doesn’t mean learning new software.
Where it falls short
- Just a 1-year warranty at a $1,599 price point. Pool Nerd calls this “the shortest coverage of any Dolphin I’d recommend at this price” — cheaper Dolphin models like the Escape carry 2 years, and pricier flagships like the Sigma carry 3.
- Standard filtration, not NanoFilter. Despite its flagship-adjacent price, the Titan uses the same Combine Filter Kit tier as cheaper Dolphin robots rather than the fine-particle NanoFilter tech on the Quantum or Sigma.
- No remote control and no delay-start feature, both absent per Maytronics’ own spec sheet — minor, but worth knowing if you’ve used a Dolphin model that had either.
- Pool Nerd’s overall verdict is “Disapproved.” The reviewer’s bottom line: it cleans well, but the combination of short warranty and standard filtration makes it a weak value next to Maytronics’ own Max-Series and ProLine alternatives at similar money.
Dolphin Nautilus Titan vs the alternatives
| Model | Max pool size | Suction | Warranty | Price |
|---|---|---|---|---|
| Nautilus Titan | 50 ft | 5,000 GPH (Maytronics, unverified) | 1 year | $1,599 |
| 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 |
| Dolphin Sigma | Large pools | 4,500 GPH | 3 years | ~$1,499 |
The Titan is genuinely cheaper than the Explorer E70 for the same 50 ft rating and the same claimed suction — but the $500 you save disappears fast if anything breaks in year two, since the E70 covers that year and the Titan doesn’t. The Dolphin Sigma is an even sharper comparison: it typically costs less than the Titan (~$1,499 vs $1,599) while carrying a 3-year warranty and gyroscope-based navigation the Titan doesn’t have. For a lower-cost 50 ft option with real warranty coverage, see the Explorer E50 review; for the complete current Dolphin lineup, see the best Dolphin pool cleaner guide.
Who should buy the Nautilus Titan
Buy it if you specifically want Maytronics’ highest claimed suction figure at a lower upfront cost than the Explorer E70, and you’re comfortable self-insuring past year one.
Look elsewhere if a longer warranty matters more than saving $500 upfront (the Explorer E70 or Dolphin Sigma both cover 2-3x longer), if you want NanoFilter fine-particle filtration (neither the Titan nor the Explorer line offers it), or if you’d rather trust an independent reviewer’s bottom line — Pool Nerd’s own verdict on the Titan is a hard pass.
The bottom line
The Dolphin Nautilus Titan cleans as well as Pool Nerd’s testing expected from a $1,599 Maytronics robot — strong suction, confident wall-climbing, full waterline coverage. What it doesn’t do is back that performance with a warranty that matches the price: 1 year, shorter than cheaper Dolphin models and a fraction of what the similarly-priced Sigma or pricier Explorer E70 offer. If the warranty gap doesn’t bother you, it’s a capable 50 ft cleaner. If it does, the Sigma is the harder competitor to beat at nearly the same money.
