A robotic pool skimmer is not the same thing as a robotic pool cleaner. A skimmer cleans the water surface. A cleaner usually vacuums the floor and may climb walls or scrub the waterline. If your pool surface is always covered in leaves, bugs, pollen, or flowers, a skimmer may help more than another floor robot.

The short version
Start with the problem your pool actually has. Leaves, fine dust, wall grime, waterline scum, floating debris, and above-ground floor dirt are not the same job. The best robot is the one that handles your must-have cleaning area without forcing you to pay for features you do not need.

Dedicated skimmer vs all-in-one robot
Choose a dedicated skimmer if you already have floor cleaning handled. Choose an all-in-one robot if you need surface cleaning and underwater cleaning from one machine.
What skimmers do not do
Dedicated skimmers do not vacuum the floor, scrub walls, clean dead algae, or brush the waterline.
Best two-robot setups
For heavy leaves, pair Beatbot iSkim Ultra, Aiper Surfer S2, or Betta SE Plus with a floor robot like Dolphin Premier, Dolphin Quantum, or Nautilus CC Plus Wi-Fi.
Common mistakes
Mistake 1: Buying a skimmer when the floor is dirty
A skimmer only cleans the surface.
Mistake 2: Buying a floor robot for floating leaves
A floor robot waits until debris sinks.
Mistake 3: Ignoring basket size
Leaves require basket capacity.
Mistake 4: Expecting solar to mean maintenance-free
Solar helps charging, not basket cleaning.
Final verdict
Beatbot iSkim Ultra is the premium skimmer pick. Aiper Surfer S2 is the value/app-connected solar skimmer. Betta SE Plus is the simple solar skimmer. Beatbot Sora 70 is the best all-in-one option if you want surface plus underwater cleaning.
