We tested the Scuba N1 in a 24-foot round above-ground pool for 6 weeks and analyzed 12,000+ Amazon reviews. Here's why it's our top pick for medium to large above-ground pools — and when to save your money on the SE instead.
4.1/5
Our Rating
Bottom Line:
The Aiper Scuba N1 is the best robotic pool cleaner for medium to large above-ground pools under $350. Dual suction ports, 2-layer filtration, and smarter PVC navigation make it a meaningful upgrade over the Scuba SE. If your pool is over 250 sq ft — especially if you deal with algae or fine debris — the extra $170 over the SE is money well spent. The only real reason to choose the SE over the N1 is if you have a very small pool (under 200 sq ft) where the SE's simpler design is more than enough.

The most important difference between the Scuba N1 and SE is the dual suction port system. Instead of one intake, the N1 pulls water through two ports simultaneously — creating noticeably stronger suction and wider debris capture per pass.
In practice, this means:
After 6 weeks of testing the N1 in a 24-foot round pool (452 sq ft), we consistently found less residual debris per run versus the SE's performance in the same pool size earlier in the season.
The Scuba N1 uses PVC Smart Path navigation — a step up from the SE's simple gyroscope-only approach. The N1 uses pool boundary detection combined with algorithmic path planning to create more systematic cleaning patterns.
Real-world result: in our testing, the N1 covered approximately 92–95% of the pool floor per session, compared to 85–90% for the SE. The improvement is most noticeable in rectangular pools where the N1 makes parallel passes rather than the SE's more random pattern.
Corner coverage is still not perfect — very tight 90-degree corners in rectangular pools may require occasional manual touch-up. But the improvement over the SE is meaningful for medium and large above-ground pools.
The Scuba N1 shares the same 90-minute battery rating as the SE. Our concern about battery degradation applies here too — real-world reports show similar patterns of capacity reduction over 6–12 months.
However, the N1 makes better use of the 90 minutes available due to its more efficient navigation. For a 400–500 sq ft pool, 90 minutes is generally enough to complete a full clean even with some navigation inefficiency. The SE's less systematic path can fail to complete coverage before the battery runs out on the same size pool.
"Upgraded from the Scuba SE after one season and the difference is immediately obvious. My 24-foot round pool gets a much more thorough clean. The suction is stronger and it actually picks up the fine stuff that the SE was leaving behind. Worth the extra money for sure."
"I have a 27-foot round above-ground pool and I was worried the 90 minutes might not be enough. It finishes in about 75 minutes and the pool looks great. Haven't had to manually vacuum once since I got it. The battery is still holding up well after 8 months."
"It's a good robot but I think the SE does 90% of what this does for $170 less. If I had to do it again with a small pool (15ft round) I'd just buy the SE. The dual suction and smarter navigation only matter if you have a bigger pool."
| Scuba SE | Scuba N1 | |
|---|---|---|
| Price | ~$130 | ~$300 |
| Suction | Single port | Dual ports |
| Filter | 1-layer | 2-layer |
| Navigation | Gyroscope | PVC Smart Path |
| Coverage/session | 85–90% | 92–95% |
| Best for | Small pools <200 sq ft | 250–700 sq ft |
Buy the SE if: your pool is under 200 sq ft and you only deal with leaves and large debris.
Buy the N1 if: your pool is 250+ sq ft, you have algae or fine debris, or you want more thorough cleaning.

Yes, for pools over 250 sq ft or if you have algae/fine debris issues. The dual suction, 2-layer filter, and smarter navigation make a meaningful difference. For very small pools under 200 sq ft, the SE is sufficient.
No. The N1 is floor-only and designed for above-ground pools. For in-ground pools, you need the Scuba S1 (wall-climbing, in-ground certified).
Rated for above-ground pools up to approximately 700 sq ft on a single 90-minute charge. In practice, most 27-foot round pools (572 sq ft) are fully covered per session.
PVC Smart Path uses pool boundary sensors to plan a more systematic cleaning route — parallel passes vs. the SE's more random gyroscope pattern. Result: better corner coverage and higher percentage of pool floor cleaned per session.
Significantly better. The 2-layer filter plus dual suction captures algae, pollen, and fine sand that the SE's single-layer system misses. If you have fine debris problems, the N1 is the right choice.
