The verdict: Aiper for fine debris, Beatbot for leaves. This is unusually clean as brand comparisons go, because the two companies have made genuinely different engineering bets and both publish enough to prove it.
What Aiper optimizes for
Filtration fineness and hands-off ownership. Aiper publishes 3-micron filtration on the Scuba X1 Pro Max and the Obsidian — the finest figures published by any brand on this site. It also ships wireless charging docks on the Obsidian and Scuba V3, so the robot recharges and re-runs without you lifting it out.
Aiper’s range is also the broadest: $130 for the Scuba SE through $2,500 for the top X1 Pro Max configuration, with real products at nearly every point between.
What Beatbot optimizes for
Debris volume and coverage breadth. Beatbot publishes 5-liter baskets on the Sora 10 and 30 and a 9-liter basket on the iSkim skimmer — the largest capacities here. The Sora 70 and AquaSense 2 Ultra both skim the surface as well as cleaning the floor, walls and waterline, which only one Aiper (the X1 Pro Max) does.
Beatbot’s weakness on paper is filtration disclosure: the Sora 10 publishes 150 micron, and most of the rest publish no micron figure at all. That is a real gap when your debris is fine.
Head to head on the specs that matter
| Aiper | Beatbot |
|---|
| Finest published filtration | 3 micron (X1 Pro Max, Obsidian) | 150 micron (Sora 10); others unpublished |
| Largest published basket | 4 L (EcoSurfer S2 skimmer) | 9 L (iSkim), 5 L (Sora 10/30) |
| Highest published suction | 8,500 GPH (X1 Pro Max) | 6,800 GPH (Sora line) |
| Charging dock | Obsidian, Scuba V3 | AquaSense 2 Ultra |
| Surface skimming in one unit | X1 Pro Max | Sora 70, AquaSense 2 Ultra |
| Entry price here | $130 (Scuba SE) | $359 (iSkim) |
| Replacement batteries available | Yes, third-party for Scuba S1 | Not established |
Parts and longevity
Aiper has the edge, and it is worth weighing. Third-party 8 Ah replacement packs for the Scuba S1 exist at around $80, aftermarket filter cloths are widely available, and chargers are $10. Beatbot sells genuine filter baskets — $60 for the AquaSense 2, $100 for the Ultra’s dual basket — which is good for fit and expensive to run, and third-party battery support is not established. Filters by brand has the figures.
So which one
- Sand, silt, pollen, post-algae cloudiness → Aiper Obsidian or X1 Pro Max. Nothing from Beatbot publishes a comparable micron figure.
- Oak leaves, maple, heavy seasonal fall → Beatbot Sora 10 or 30. The 5-liter basket is the whole argument.
- Pine needles or continuous surface debris → Beatbot Sora 70 or iSkim, because surface interception is the only real answer.
- Waterline film → Beatbot AquaSense 2 (double pass) or Aiper S1 Pro (horizontal pass). Close, slight edge to Beatbot.
- Lowest cost of ownership over five years → Aiper, on parts availability.
If you want a third option in the frame, the three-way against Dolphin adds the corded case.
