The Beatbot AquaSense 2 Pro delivers up to 11 hours of surface cleaning, 5-in-1 functionality and a three-year warranty, making it a powerful option for medium-large pools. Its trade-offs include a heavier chassis and modest filter capacity, and it omits the AI-driven mapping of the Ultra version. Ideal for owners who need extensive cleaning capabilities without the premium AI features.
The Aiper Scuba S1 is a high-end cordless robotic pool cleaner delivering industry-leading suction and a long 180-minute runtime. Its premium price and heavy chassis make it less suitable for budget-focused or portable users. Best for large in-ground pools needing thorough cleaning.
The iGarden K36 is a cordless robotic pool cleaner with strong 3D navigation and a long 220-minute floor-only runtime. Its main trade-offs are a heavy water-filled weight and occasional connectivity hiccups. Best suited for owners of smaller inground or above-ground pools who value smart scheduling and fine-debris filtration.
The Beatbot AquaSense 2 is a cordless robot that offers four-hour runtime, strong suction and sophisticated sensor-based navigation. Its main trade-offs are the lack of surface-cleaning capability and a relatively heavy unit. Best suited for owners of in-ground or above-ground pools up to 3,230 sq ft who value long runtime and smart features.
The Reriou SAT25 is a cordless pool robot featuring sonar navigation, caterpillar treads and dual 180 W brushless motors for robust cleaning. It lacks connectivity features and clear warranty information, which may concern some buyers. Suitable for users who prioritize solid hardware and multiple cleaning modes over smart app integration.
The Zyerch SAT25 is a cordless robotic pool vacuum offering up to 150 minutes of runtime, strong 4800 GPH suction and wall-climbing sonar navigation. Its low ground clearance and relatively heavy wet weight may hinder use on deep steps or frequent handling. Ideal for homeowners seeking long cordless operation for pools up to 50 ft.

Although direct user reviews are scarce, the available commentary suggests owners value the cordless convenience, single-session full-pool cleaning and easy maintenance. The most common positive remarks focus on the app control and the ability to tackle floors, walls and waterlines without manual effort.
“didn't miss any spots”
“filter capacity (~3.7L seen as small vs. 4-5L preferred)”
“cordless workhorse”
Professional reviewers agree that the Aiper Scuba X1 Pro Max sets a new benchmark for suction and runtime, delivering unmatched cleaning power for large in-ground pools. However, they also note its premium price, heavy chassis, and limited automation features as trade-offs that may deter budget-oriented buyers.
Consumers overwhelmingly praise the robot's thorough, spot-free cleaning and the freedom of a cordless system, but they consistently flag the heavy weight, long charge time, and the need for regular filter upkeep as pain points.
Professional reviewers commend the K36 for its lightweight build, effective fine-debris filtration, and robust 3D navigation with a turbo boost for stubborn stains. However, they caution that the heavy water-filled weight, occasional connectivity hiccups, and reliance on future firmware for full wall cleaning are drawbacks.
There are currently no consumer reviews or user‑generated feedback available, so everyday user sentiment cannot be assessed at this time.
Professional reviewers consider the AquaSense 2 Pro to be essentially the Ultra's hardware stripped of AI extras, delivering the same suction, battery life, and filtration at a lower price point. They commend its robust 5-in-1 cleaning, reliable CleverNav™ navigation, ClearWater clarification and the generous three-year warranty, while noting the heavier weight and missing AI camera as the main trade-offs.
Pool owners praise the Pro for its ability to clean medium-large pools in a single charge, easy filter access and the skin-safe ClearWater system. The most common criticism from everyday users is the modest filter capacity, which can require more frequent emptying when dealing with heavy leaf or sand loads.
Professional reviewers describe the SAT25 as a robust, cordless workhorse that combines solid construction, side‑profile wheels, underwater brushes, and a quick‑latch debris door. They commend its sonar‑guided navigation and wall‑climbing ability, as well as the extended 150‑minute runtime, while noting the low ground clearance and wet weight as potential drawbacks in real‑world use.
Everyday users echo the professional praise for cordless convenience, long runtime, and easy debris emptying, highlighting the wall‑climbing function as a major benefit. The main consumer concerns revolve around the unit’s weight when wet and questions about durability of the low‑clearance design, though no widespread complaints have emerged yet.
