We have tested both the Aiper Scuba X1 and the Polaris VRX iQ+ in real pools, measured their suction at the intake, and lived with the filtration and daily routine each one requires. This comparison brings those results together so you can see the real-world trade-offs without relying on the numbers printed on either box.
This is also a corded-versus-cordless decision: one prioritizes continuous power and scheduling, while the other removes the cable but adds charging.
The short answer: Polaris VRX iQ+ takes the head-to-head edge. Its app, weekly timer, seven modes, and easy-rinse basket make ownership convenient. Aiper Scuba X1 only makes sense for buyers committed to the X1 design who want the lowest entry price. Because neither robot is in our top recommendation tier, we also suggest cross-shopping the Dolphin Sigma (2.0 PSI) before you buy.
Quick Answer
Between these two, pick the Polaris VRX iQ+ for Polaris owners who care more about app polish and modes than raw suction. It is the more complete option across the measurements and ownership factors we tested.
Consider the Aiper Scuba X1 only if you specifically prioritize buyers committed to the X1 design who want the lowest entry price — and compare both against our recommended Dolphin Sigma (2.0 PSI) before checking out.
Our calls in the full reviews are Not recommended for the Aiper Scuba X1 and Decent, but there are better buys for the Polaris VRX iQ+. Those calls matter here: PSI is the first round, not the entire verdict.
Suction Power: 1.2 PSI vs 1 PSI
On our hydro manometer, the Aiper Scuba X1 measured 1.2 PSI and the Polaris VRX iQ+ measured 1 PSI. That gives the Aiper Scuba X1 a 0.2 PSI advantage, or about 20% more intake pressure than the lower reading.
We measure pressure directly at the intake with the same gauge and pool setup. That is different from manufacturer flow-rate claims in gallons per hour: GPH describes water movement, while PSI shows how hard the intake pulls on debris. Cordless results are recorded at full charge. Our complete pool-robot suction test explains the method and shows where both robots sit on the full board.
The number needs context. It is easy to set up, looks polished, and beats the X1 Pro on canonical measured suction. Its app, weekly timer, seven modes, and easy-rinse basket make ownership convenient. The stronger gauge result gets this round, though intake pressure alone cannot make up for a filter that lets fine debris escape or a routine that makes you handle the robot every day.
Filtration and Debris Handling
The Aiper Scuba X1 uses basic mesh basket. The Polaris VRX iQ+ uses large five-liter mesh canister.
We give the filtration edge to the Polaris VRX iQ+. Our comparison favors fine-particle capture, usable debris capacity, easy cleaning, and whether the better filter is included rather than sold as an upgrade.
For leaves, capacity and intake design matter. For pollen, silt, and the haze that dulls otherwise clear water, the filter media matters more. A basic mesh screen can look clean after a run while still passing the smallest material back into the pool.
Automation and Daily Work
The Aiper Scuba X1 is cordless. Simple app setup, but the connection drops underwater and charging is daily. The Polaris VRX iQ+ is corded. Feature-rich iAquaLink app with scheduling and multiple cleaning modes.
That power difference changes the ownership routine. The corded robot can keep full power through the cycle and run from a schedule when its controls support one. The cordless robot removes the floating cable, but it must come out of the water to recharge. For frequent cleaning, that usually means deploying and retrieving it every day.
The automation round goes to the Polaris VRX iQ+.
Coverage and Pool Fit
For the Aiper Scuba X1, our review found floor, walls, and waterline in cordless cycles. The Polaris VRX iQ+ is built for floor, walls, and waterline with a lift system.
The Polaris VRX iQ+ wins the coverage round on the breadth of surfaces and pool situations it can handle.
This is where the runner-up can still be the smarter fit for specific pools. A compact pool does not benefit from paying for reach it cannot use, while a pool with a sun shelf, long waterline, or heavy leaf load can expose the limits of a simpler machine quickly.
Value: Performance for the Money and Time
Our value take on the Aiper Scuba X1: The least costly X1, though stronger corded cleaners remain the better use of the budget. For the Polaris VRX iQ+: Excellent controls, but weak measured pull and basic filtration at a premium price.
We score value evenly. In that case, your pool fit should break the tie.
Value is not the same thing as the lowest checkout price. We count cleaning power, filtration, how many surfaces the robot covers, and how often you have to retrieve or charge it. A cheaper robot that leaves you vacuuming behind it is not a bargain, and an expensive robot only earns its price when its extra capability solves a real problem in your pool.
Recommended Upgrade to Cross-Shop: Dolphin Sigma
Neither model in this comparison sits in our top recommendation tier. Before buying, compare them against the Dolphin Sigma (2.0 PSI): Closest smart-flagship alternative: boosts suction from 1.0–1.2 PSI to 2.0 PSI across a 10-inch dual intake, includes top-load pleated NanoFilters, and keeps full underwater Wi-Fi app control with a 3-year warranty.

Which One Should You Buy?
- Head-to-head pick — Polaris VRX iQ+: Best here for Polaris owners who care more about app polish and modes than raw suction. Its app, weekly timer, seven modes, and easy-rinse basket make ownership convenient.
- When Aiper Scuba X1 fits: Only for buyers committed to the X1 design who want the lowest entry price. It is easy to set up, looks polished, and beats the X1 Pro on canonical measured suction.
- Know the main drawback: Polaris VRX iQ+ — At 1.0 PSI, it delivers about half the suction of the strongest similarly priced cleaners. Aiper Scuba X1 — Its 1.2 PSI, basic filter, underwater app disconnect, and recharge routine limit the value.
Final Verdict
Polaris VRX iQ+ takes this head-to-head. Polaris VRX iQ+ wins this head-to-head. Its app, weekly timer, seven modes, and easy-rinse basket make ownership convenient. Aiper Scuba X1 remains the better fit for buyers committed to the X1 design who want the lowest entry price, while the Dolphin Sigma is our top-rated step-up near this class.
