Scuba S1 Pro vs Scuba X1 Pro Max
Both are Aiper flagships — but for different jobs. The S1 Pro is the underwater specialist: quad motors, 6,600 GPH, wall-climbing, up to 2,150 sq ft. The X1 Pro Max is the all-in-one: 9 motors, 8,500 GPH, wall-climbing PLUS surface skimming, up to 3,230 sq ft. Which one fits your pool?
Choose the S1 Pro if your pool is under 2,150 sq ft and surface debris isn’t a major problem — you get flagship underwater cleaning (floors, walls, waterline) with 3-micron micromesh filtration at a lower price. Choose the X1 Pro Max if your pool is larger (up to 3,230 sq ft), you have heavy floating debris (leaves, pollen), or you want to replace a separate surface skimmer. The S1 Pro cannot skim the surface; the X1 Pro Max weighs nearly twice as much and costs significantly more. These two models use different filter and brush systems — accessories are not cross-compatible.

When to Choose the Scuba S1 Pro
The S1 Pro is Aiper’s underwater flagship — purpose-built for pools where most debris sinks. Its quad-motor system with 6,600 GPH suction handles floors, walls, and waterline scrubbing with 180-minute runtime on a single charge. The 3-micron micromesh filter captures fine particles (algae spores, mineral crystals) that cheaper filters miss, reducing chemical demand. Choose the S1 Pro when: (1) your pool is under 2,150 sq ft, (2) surface debris isn’t a daily problem (leaves sink quickly in your climate), (3) waterline scum is your biggest frustration, and (4) you want flagship cleaning performance without paying the X1 Pro Max premium.

When to Choose the Scuba X1 Pro Max
The X1 Pro Max is the no-compromise flagship for large or debris-heavy pools. Its 9-motor Dual-Jet system delivers 8,500 GPH — the strongest suction in Aiper’s lineup. The defining feature is surface skimming: it can run up to 10 hours in surface-only mode, collecting floating leaves, pollen, and dust before they sink. OmniSense™ 3D mapping provides the most advanced path planning across complex pool geometries (freeform, L-shaped, deep ends). Choose the X1 Pro Max when: (1) your pool exceeds 2,150 sq ft, (2) floating debris is a daily battle, (3) you want to eliminate a separate surface skimmer, or (4) you want optional HydroComm Pro for real-time underwater remote control and water quality monitoring.
Key Trade-offs: S1 Pro vs X1 Pro Max
Surface skimming is the dividing line. If you never fight floating debris, the S1 Pro’s underwater-only design is not a limitation — it’s a cost saving. If you regularly skim leaves or pollen off the surface, the X1 Pro Max’s surface mode eliminates that manual chore entirely.
Pool size matters. The S1 Pro is rated for pools up to 2,150 sq ft. If your pool is larger, the battery may not last a full clean cycle, and the navigation system isn’t optimised for very large footprints. The X1 Pro Max handles up to 3,230 sq ft with 3D mapping for complex shapes.
Weight vs Power. The X1 Pro Max (~33 lbs) is significantly heavier than the S1 Pro. If you need to lift the robot out daily and upper-body strength is a concern, the S1 Pro is the more practical choice.
HydroComm Pro. Only the X1 Pro Max supports HydroComm Pro for live underwater control. If you want to manually pilot the robot to spot-clean specific areas, the S1 Pro cannot do this.
S1 Pro Owners Considering an Upgrade
If you already own an S1 Pro, upgrade to the X1 Pro Max when: (1) you’ve moved to a larger home with a bigger pool, (2) you’re spending more time manually skimming the surface than the robot saves you on floor/wall cleaning, or (3) you want HydroComm Pro for remote-controlled spot cleaning. The S1 Pro cannot be retrofitted with surface skimming or HydroComm support. See our X1 vs X1 Pro vs X1 Pro Max comparison to confirm the X1 Pro Max is the right X1 tier for your needs.
