ECOVACS Ultramarine P1 and Aiper Scuba X1 Pro Max occupy different price tiers. P1 is the starting point if you want an affordable cordless robot for floors and walls. Aiper adds advertised water-surface cleaning and a broader premium package. The question is whether those extra jobs matter in your pool. This is a budget-versus-premium buying comparison, not a claim that the products are direct equivalents. Specifications come from official US pages; SRR checked current US offers on October 22, 2026. Matched SRR cleaning tests are unavailable.

Summary
Start with P1 for floor-and-wall cleaning when surface debris is already managed. Investigate X1 Pro Max when surface cleaning is a priority and the complete package fits your budget.
Choose Ecovacs Ultramarine P1
You want to spend less and mainly need debris removed from floors and walls. Check that the advertised pool-size limit and your pool geometry fit.
Choose Aiper Scuba X1 Pro Max
You specifically want advertised surface cleaning alongside submerged cleaning. Confirm bundle contents and accessory costs before comparing value.
In short
Start with Ultramarine P1 when floor-and-wall cleaning is the job and surface debris is already under control. Investigate Scuba X1 Pro Max when you specifically need its advertised surface-cleaning capability and can justify the complete price. Confirm pool compatibility first; specifications alone do not establish a cleaning winner.

Key differences
The practical differences between these models, explained in plain terms.
First separate settled debris from floating debris
Start with the work your current equipment leaves behind. If the skimmer catches most floating leaves but the floor still collects sand and debris, paying for surface cleaning may be unnecessary. P1 is the lower-cost candidate to investigate for that workload. If floating debris is the chore you repeatedly handle yourself, Aiper's advertised surface mode becomes relevant. That does not establish how quickly it clears your particular pool or how well it handles wind-driven debris. Keep expectations tied to evidence and the seller's return conditions. The pool-cleaner buying guide helps define those jobs before choosing a price tier.
Do not decide from suction or filter numbers alone
Both brands advertise fine-particle filtration, but similar micron claims do not establish equal whole-pool results. Filter configuration, loading, cleaning routes and the debris mixture all matter. Ask about the correct media for your pool and check how it should be cleaned or replaced. There are no matched SRR pickup, wall-coverage or filter-loading tests for this pair. We do not use headline flow rates to declare a winner. Likewise, a larger advertised pool-area limit is a compatibility starting point, not a guarantee that an unusual shape will be fully covered in one run. Tell the manufacturer about steps, shallow shelves, drains, slopes and the pool finish. For a larger or more complicated pool, broaden the shortlist with our large-pool cleaner guide.
Check controls, accessories and maintenance
Do not assume app control means every command works while a robot is submerged. Aiper promotes underwater communication through HydroComm Pro; confirm whether that accessory is included in the offer you are considering. Check P1's communication and scheduling conditions in its regional manual as well. Compare the actual packages rather than the largest collection of accessories shown in promotional images. A caddy, extra filter or communication accessory can change the delivered cost. Confirm the exact model name and included equipment with the seller. Both options still require handling, charging and filter care. Choose a storage and service location you can use comfortably, and follow the manufacturer's instructions for retrieval and seasonal storage. The cordless pool cleaner guide offers more battery-powered alternatives.
When spending more is justified
SRR recorded fresh available US offers for both models on October 22, 2026, with P1 substantially lower-priced. Deals and kit contents can change; compare current delivered totals, compatible replacement filters and return terms before buying. Aiper is easier to justify when its additional cleaning jobs would remove work you currently do yourself. It is harder to justify if you mostly want a basic floor-and-wall routine and already have effective surface skimming. If the budget tier suits you better, compare P1 with the wider pool cleaners under $1,000. For other Aiper choices, use the Aiper lineup guide. Neither comparison requires you to choose the most expensive model.
Sources and limits
Hardware sources checked October 22, 2026: ECOVACS Ultramarine P1 US page and Aiper Scuba X1 Pro Max US page. US product identity and offer freshness also use SRR commerce records. Manufacturer specifications are not independent performance results. We leave P1 surface skimming unconfirmed rather than inferring it from broader cleaning language.
Which should you buy?
Choose ECOVACS Ultramarine P1
- Your main cleaning problem is settled debris and dirty walls.
- Your existing skimmer or routine already handles floating debris.
- You want the lower-cost offer at the latest check.
Choose Aiper Scuba X1 Pro Max
- Floating leaves or insects are an important part of your workload.
- You want to investigate one robot for advertised floor, wall, waterline and surface cleaning.
- You accept the premium cost and will verify exact accessories.
Final verdict
Start with Ultramarine P1 when floor-and-wall cleaning is the job and surface debris is already under control. Investigate Scuba X1 Pro Max when you specifically need its advertised surface-cleaning capability and can justify the complete price. Confirm pool compatibility first; specifications alone do not establish a cleaning winner.
Frequently asked questions
Does Ultramarine P1 skim floating debris?
Surface skimming is not established in the official P1 specification used here. Do not buy it assuming that capability.
Why consider Aiper if P1 is cheaper?
Aiper advertises a wider range of cleaning areas, including the water surface. That extra job may matter if floating debris is a recurring chore.
Do both have fine filters?
Both manufacturers advertise fine-particle filtration. Similar micron figures do not establish equal cleaning results or filter maintenance.
Which is better for a large pool?
Check the published area limits and your actual pool geometry. Aiper advertises a higher area limit, but matched SRR coverage tests are unavailable.
