How to choose without overbuying
Start with the real job
Choose by your pool geometry: full smart floor-to-wall-to-waterline cleaning, floor-only flat bottom cleaning, or system charger updates.
Price is not the brief
Use the current price as a filter, then check whether the product solves the exact room, routine, or setup problem you have.
Respect the watch-out
Every pick includes a tradeoff so the recommendation stays useful instead of turning into a product list with buttons.
FAQ
Does it get stuck on pool drains?
No, both models feature automatic obstacle backing and side-thruster sensors that detect high main drains and push the robot off them automatically.
How does the robot retrieve itself when the battery is low?
When the battery drops below 10%, the robot automatically drives to the pool wall, parks, and waits to be lifted out with the included hook tool.
Can I use this in saltwater pools?
Yes, but we strongly recommend rinsing the robot with fresh tap water after every clean to prevent salt crusting in the motor bearings.
What should I check before ordering?
Check pool bottom slopes, wall liner materials, filter replacement sizes, and battery charge docks.
