We have tested both the Beatbot AquaSense 2 Ultra 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 Premier (2.2 PSI). If you are strictly choosing between these two models, the Dolphin Explorer E70 is the lesser compromise (pulling 1.7 vs 1.6 PSI on our gauge).
Quick Answer
Our honest call is to skip both robots and buy the Dolphin Premier instead. Our #1 overall pick near this price bracket: jumps from 1.6–1.7 PSI to a leaderboard-leading 2.2 PSI, includes Multi-Media NanoFilters plus a leaf bag, and automates daily cleaning on a weekly timer. If your priorities lean more toward buyers who want near-Premier power with full app control, also look at the Dolphin Sigma (2.0 PSI).
If you are already committed to one of these two, Dolphin Explorer E70 takes the narrow edge (pulling 1.7 vs 1.6 PSI on our gauge). The Beatbot AquaSense 2 Ultra is only worth considering for buyers who insist on one cordless machine for floor and surface modes regardless of price.
Our calls in the full reviews are Not recommended for the Beatbot AquaSense 2 Ultra and Not recommended for the Dolphin Explorer E70. Those calls matter here: PSI is the first round, not the entire verdict.
Suction Power: 1.6 PSI vs 1.7 PSI
On our hydro manometer, the Beatbot AquaSense 2 Ultra measured 1.6 PSI and the Dolphin Explorer E70 measured 1.7 PSI. That gives the Dolphin Explorer E70 a 0.1 PSI advantage, or about 6% 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 packs the widest Beatbot feature list and posts 1.6 PSI on a full charge. 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 Beatbot AquaSense 2 Ultra uses small dual-layer mesh basket. 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 Beatbot AquaSense 2 Ultra is cordless. Many app features, but underwater connection and daily charging remain limitations. 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 Beatbot AquaSense 2 Ultra, 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 Beatbot AquaSense 2 Ultra: The most expensive Beatbot while matching the base model's canonical full-charge PSI. 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 Beatbot AquaSense 2 Ultra 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 Premier:
| Category | AquaSense 2 Ultra | Explorer E70 | Premier (Buy Instead) |
|---|---|---|---|
| Our review call | Skip | Skip | Recommended |
| Measured suction | 1.6 PSI (full charge) | 1.7 PSI | 2.2 PSI (constant corded) |
| Filtration | Small dual-layer mesh basket | Top-loading mesh basket without the filter versatility of the ProLine picks | Multi-Media filtration with NanoFilters, standard cartridges, and the only leaf bag in this group |
| Automation | Many app features, but underwater connection and daily charging remain limitations | Connected app control and scheduled corded cleaning | Weekly timer on the power supply; no daily charging |
Our #1 overall pick near this price bracket: jumps from 1.6–1.7 PSI to a leaderboard-leading 2.2 PSI, includes Multi-Media NanoFilters plus a leaf bag, and automates daily cleaning on a weekly timer.
You can also read our direct head-to-head breakdowns for Beatbot AquaSense 2 Ultra vs Dolphin Premier and Dolphin Explorer E70 vs Dolphin Premier, or look at the Dolphin Sigma (2.0 PSI) if your pool leans more toward buyers who want near-Premier power with full app control.
If You Still Pick Between These Two
- Lesser compromise — Dolphin Explorer E70: Takes the head-to-head edge (pulling 1.7 vs 1.6 PSI on our gauge). Its 1.7 PSI reading, navigation, app, and three-year warranty make it a capable cleaner.
- Narrow case for Beatbot AquaSense 2 Ultra: Only relevant for buyers who insist on one cordless machine for floor and surface modes regardless of price. It packs the widest Beatbot feature list and posts 1.6 PSI on a full charge.
- Why we skip both overall: Dolphin Explorer E70 — At its normal price, the Premier and Sigma deliver more suction and better filtration. Beatbot AquaSense 2 Ultra — Its tiny basket, daily battery routine, and flagship price are difficult to justify.
Final Verdict
Skip both — buy the Dolphin Premier instead. Dolphin Explorer E70 edges out Beatbot AquaSense 2 Ultra in a forced comparison (pulling 1.7 vs 1.6 PSI on our gauge), but both carry a Not recommended call in our reviews. The Dolphin Premier (2.2 PSI) is the closest recommended robot to buy instead.
