We have tested both the Aiper Scuba X1 Pro Max and the Dolphin Explorer E70 in real pools, measured their suction at the intake, and lived with the filtration and daily routine each one requires. This comparison brings those results together so you can see the real-world trade-offs without relying on the numbers printed on either box.
This is also a corded-versus-cordless decision: one prioritizes continuous power and scheduling, while the other removes the cable but adds charging.
The short answer: we recommend skipping both. Neither robot earned a buy call in our pool testing. If you want our closest recommended alternative for what you are shopping here, look at the Dolphin Sigma (2.0 PSI). If you are strictly choosing between these two models, the Dolphin Explorer E70 is the lesser compromise (pulling 1.7 vs 1.3 PSI on our gauge).
Quick Answer
Our honest call is to skip both robots and buy the Dolphin Sigma instead. Closest smart-flagship alternative: boosts suction from 1.3–1.7 PSI to 2.0 PSI across a 10-inch dual intake, includes top-load pleated NanoFilters, and keeps full underwater Wi-Fi app control with a 3-year warranty. If your priorities lean more toward leafy pools and owners who want the strongest pull we have measured, also look at the Dolphin Premier (2.2 PSI).
If you are already committed to one of these two, Dolphin Explorer E70 takes the narrow edge (pulling 1.7 vs 1.3 PSI on our gauge). The Aiper Scuba X1 Pro Max is only worth considering for Aiper loyalists who want the broadest X1 feature set.
Our calls in the full reviews are Not recommended for the Aiper Scuba X1 Pro Max and Not recommended for the Dolphin Explorer E70. Those calls matter here: PSI is the first round, not the entire verdict.
Suction Power: 1.3 PSI vs 1.7 PSI
On our hydro manometer, the Aiper Scuba X1 Pro Max measured 1.3 PSI and the Dolphin Explorer E70 measured 1.7 PSI. That gives the Dolphin Explorer E70 a 0.4 PSI advantage, or about 31% more intake pressure than the lower reading.
We measure pressure directly at the intake with the same gauge and pool setup. That is different from manufacturer flow-rate claims in gallons per hour: GPH describes water movement, while PSI shows how hard the intake pulls on debris. Cordless results are recorded at full charge. Our complete pool-robot suction test explains the method and shows where both robots sit on the full board.
The number needs context. It is the strongest X1 model on our gauge and adds broad coverage with an easy top-load basket. Its 1.7 PSI reading, navigation, app, and three-year warranty make it a capable cleaner. The stronger gauge result gets this round, though intake pressure alone cannot make up for a filter that lets fine debris escape or a routine that makes you handle the robot every day.
Filtration and Debris Handling
The Aiper Scuba X1 Pro Max uses top-loading mesh basket with a fabric-style fine layer. The Dolphin Explorer E70 uses top-loading mesh basket without the filter versatility of the proline picks.
We give the filtration edge to the Dolphin Explorer E70. Our comparison favors fine-particle capture, usable debris capacity, easy cleaning, and whether the better filter is included rather than sold as an upgrade.
For leaves, capacity and intake design matter. For pollen, silt, and the haze that dulls otherwise clear water, the filter media matters more. A basic mesh screen can look clean after a run while still passing the smallest material back into the pool.
Automation and Daily Work
The Aiper Scuba X1 Pro Max is cordless. App setup, but underwater control requires the separate HydroComm accessory. The Dolphin Explorer E70 is corded. Connected app control and scheduled corded cleaning.
That power difference changes the ownership routine. The corded robot can keep full power through the cycle and run from a schedule when its controls support one. The cordless robot removes the floating cable, but it must come out of the water to recharge. For frequent cleaning, that usually means deploying and retrieving it every day.
The automation round goes to the Dolphin Explorer E70.
Coverage and Pool Fit
For the Aiper Scuba X1 Pro Max, our review found floor, walls, waterline, and surface-skimming modes. The Dolphin Explorer E70 is built for floor, walls, and waterline with smart navigation.
Coverage is a tie in our scoring, so choose around pool size, shape, and the surfaces you actually need cleaned.
Surface coverage on a spec sheet only goes so far if suction fades or the filter misses fine dust. Match the robot’s reach to your pool size, and weigh how often you are willing to handle the unit to keep those surfaces clean.
Value: Performance for the Money and Time
Our value take on the Aiper Scuba X1 Pro Max: Feature-rich and attractive, but expensive for its measured cleaning performance. For the Dolphin Explorer E70: Capable but overpriced beside stronger, better-filtering Dolphins.
We score value evenly. In that case, your pool fit should break the tie.
Value is not the same thing as the lowest checkout price. We count cleaning power, filtration, how many surfaces the robot covers, and how often you have to retrieve or charge it. A cheaper robot that leaves you vacuuming behind it is not a bargain, and an expensive robot only earns its price when its extra capability solves a real problem in your pool.
What to Buy Instead
Because both the Aiper Scuba X1 Pro Max and Dolphin Explorer E70 earned a skip in our testing, compare them directly against any pick from our Best Robotic Pool Cleaners of 2026 list below — starting with our closest match, the Dolphin Sigma:
| Category | Scuba X1 Pro Max | Explorer E70 | Sigma (Buy Instead) |
|---|---|---|---|
| Our review call | Skip | Skip | Recommended |
| Measured suction | 1.3 PSI (full charge) | 1.7 PSI | 2.0 PSI (constant corded) |
| Filtration | Top-loading mesh basket with a fabric-style fine layer | Top-loading mesh basket without the filter versatility of the ProLine picks | Top-loading pleated NanoFilter cartridges for fine dust, pollen, and silt |
| Automation | App setup, but underwater control requires the separate HydroComm accessory | Connected app control and scheduled corded cleaning | MyDolphin Plus app works underwater and supports weekly scheduling |
Closest smart-flagship alternative: boosts suction from 1.3–1.7 PSI to 2.0 PSI across a 10-inch dual intake, includes top-load pleated NanoFilters, and keeps full underwater Wi-Fi app control with a 3-year warranty.
You can also read our direct head-to-head breakdowns for Aiper Scuba X1 Pro Max vs Dolphin Sigma and Dolphin Explorer E70 vs Dolphin Sigma, or look at the Dolphin Premier (2.2 PSI) if your pool leans more toward leafy pools and owners who want the strongest pull we have measured.
If You Still Pick Between These Two
- Lesser compromise — Dolphin Explorer E70: Takes the head-to-head edge (pulling 1.7 vs 1.3 PSI on our gauge). Its 1.7 PSI reading, navigation, app, and three-year warranty make it a capable cleaner.
- Narrow case for Aiper Scuba X1 Pro Max: Only relevant for Aiper loyalists who want the broadest X1 feature set. It is the strongest X1 model on our gauge and adds broad coverage with an easy top-load basket.
- Why we skip both overall: Dolphin Explorer E70 — At its normal price, the Premier and Sigma deliver more suction and better filtration. Aiper Scuba X1 Pro Max — Its 1.3 PSI, long recharge, heavy body, and paid connectivity add-on undercut the flagship price.
Final Verdict
Skip both — buy the Dolphin Sigma instead. Dolphin Explorer E70 edges out Aiper Scuba X1 Pro Max in a forced comparison (pulling 1.7 vs 1.3 PSI on our gauge), but both carry a Not recommended call in our reviews. The Dolphin Sigma (2.0 PSI) is the closest recommended robot to buy instead.
