Quick Answer: “Aiper Scuba” isn’t one robot — it’s an eight-tier cordless lineup spanning $479.99 to $1,799. The budget N1 (about $480–600) cleans the floor with disputed wall-climbing claims, while the newer N1 Plus (about $570–700) confirms wall-climbing and adds app control on the identical suction motor; the N1 Pro (roughly $750–$1,199 depending on retailer) confirms floor/wall/waterline cleaning but scored lower in independent testing than the N1 itself; the S1 (about $550–700, best value) and step-up S1 Pro (about $1,199) also add confirmed wall-and-waterline cleaning; the X1 (about $950), X1 Pro (about $1,299) and flagship X1 Pro Max ($1,799) push suction from 6,600 up to 8,500 GPH, with only the Pro Max adding surface skimming. For most residential pools, independent reviewers and this site’s own testing both point to the Scuba S1 as the best price-to-performance pick — the pricier tiers mainly buy larger coverage ratings or features most pools don’t need.
If you searched “Aiper Scuba” trying to find one specific robot, here’s why you couldn’t: Aiper has spent the last two years stacking tier on top of tier under the same “Scuba” name, and the lineup now runs eight models deep with genuinely confusing naming (X1 vs X1 Pro vs X1 Pro Max is easy to mix up even for people who follow this category closely, and N1 vs N1 Plus is a newer source of the same confusion). Below is the plain-English breakdown of every current Scuba tier, real 2026 prices, and which one actually fits your pool.

By the numbers
- Price spread: The eight Scuba tiers span $479.99 to $1,799 — a 3.75x gap between the cheapest and priciest model carrying the same “Scuba” name.
- Suction jump: Suction climbs from 6,000 GPH on the S1 Pro to 8,500 GPH on the flagship X1 Pro Max, per Aiper’s own published specs — a 42% increase for the top tier, though independent testers on this site found the extra power doesn’t always translate to visibly cleaner results on a routinely maintained pool.
- Coverage: Ratings run from 1,600 sq ft (N1, S1) up to 3,230 sq ft (X1 Pro Max), per Aiper — more than double between the entry tier and the flagship.
- Independent score: RoboticReviews scored the budget Scuba N1 at 64/100 and the mid-tier Scuba S1 Pro at 63/100 — both lower than the cheaper standard S1’s stronger reception across three of four independent testers, a reminder that a higher price tier in this lineup doesn’t reliably mean a better-reviewed robot.
What each tier actually buys you
Scuba N1 — budget floor cleaner, disputed wall-climbing. The cheapest way into the Scuba name. Aiper’s own comparison page groups it with the entry-level floor-cleaning tier, but retailer listings and RoboticReviews’ independent test don’t agree on whether it climbs walls — check the exact listing before assuming either way. Full breakdown in our Scuba N1 review.
Scuba N1 Plus — settles the N1’s wall-climbing question, same suction. Adds a confirmed 105-degree wall-climbing spec, app control with OTA updates, and a longer 180-minute runtime over the base N1 — but keeps the identical 80 GPM motor, so the upgrade is about features, not cleaning power. At $569.99–$699.99 it now overlaps heavily with the better-proven Scuba S1. Full breakdown in our Scuba N1 Plus review.
Scuba N1 Pro — confirmed wall-and-waterline, but scored lower than the N1. Steps up coverage to 2,150 sq ft and adds confirmed floor/wall/waterline cleaning (unlike the N1’s disputed wall claims), typically found around $749.99 after rebate at Costco — though other retailers price it up to $1,199. RoboticReviews’ independent test scored it 61/100, actually below the cheaper N1’s own 64/100, citing frequent recharging and filter clogging. Full breakdown in the Scuba N1 Pro review.
Scuba S1 — floor, walls, waterline, best value. The tier most owners should actually buy. Confirmed three-surface cleaning, the strongest independent reviews of any Scuba model, and a price that undercuts the corded Dolphin Nautilus CC Plus by hundreds of dollars. It’s our top cordless pick across this site — see the full Scuba S1 review.
Scuba S1 Pro — more hardware, weaker reviews. Adds a second filtration stage and a 5-liter basket for roughly double the S1’s price, but three of four independent testers (RoboticReviews, The Pool Nerd, Poolbots) rated its real-world cleaning below the cheaper standard S1. Details in the Scuba S1 Pro review.
Scuba X1 — mid-tier flagship, split reviews. Same 6,600 GPH suction as the X1 Pro at a lower price, with full floor-wall-waterline coverage. Digital Trends called it a “solid pick”; The Pool Nerd was harsher on real-world debris pickup. Full breakdown in the Scuba X1 review.
Scuba X1 Pro — X1 hardware, native HydroComm. Per Aiper’s own comparison it shares the X1’s 6,600 GPH suction and adds built-in HydroComm pairing plus a bigger 26-sensor navigation array for real-time underwater control (an accessory on the base X1), for about $350 more. The Pool Nerd’s independent test rated it “Disapproved” — see the full Scuba X1 Pro review for why.
Scuba X1 Pro Max — the only one that skims the surface. The flagship: 8,500 GPH from 9 motors, 3,230 sq ft coverage, and the sole Scuba model that combines floor/wall/waterline cleaning with true surface skimming. Reviewers split sharply on whether that’s worth $1,799 — see the full X1 Pro Max review for both sides.
Which one should you buy?
For the overwhelming majority of residential inground pools, the Scuba S1 is the right call. It delivers full floor-wall-waterline cleaning, the best independent track record in the lineup, and a price several hundred dollars below the step-up tiers that mostly buy larger coverage ratings or features most pools don’t need.
Step up to the S1 Pro or X1 only if your pool exceeds the S1’s 1,600 sq ft rating — and even then, weigh the S1 Pro’s weaker independent reviews against the X1’s similar price and split verdict before assuming “more expensive” means “better.”
Step up to the X1 Pro Max only if floating leaves and surface debris are a real, recurring problem — it’s the only Scuba tier built for that job. If your yard is leaf-heavy but budget matters more, a dedicated pool skimmer robot paired with a cheaper floor-and-wall Scuba model can cost less than the X1 Pro Max alone.

The bottom line
“Aiper Scuba” isn’t one robot — it’s eight, spanning $479.99 to $1,799. The N1 is a budget floor cleaner with disputed wall-climbing claims, the N1 Plus settles that ambiguity and adds app control on the same suction motor, the N1 Pro confirms wall-and-waterline cleaning but scored lower in independent testing, the S1 is the price-to-performance sweet spot most owners should buy, the S1 Pro and X1 add hardware for larger pools without a clear reviews win, the X1 Pro adds native connectivity, and the X1 Pro Max is the only tier that skims the surface. Start with the S1 unless you have a specific reason to look elsewhere — it’s the model that made this entire lineup worth paying attention to.
