Buying Guide: How to Choose a Robotic Pool Cleaner

Before purchasing a robotic pool cleaner, consider these important factors.

Pool Type

Some robots are designed specifically for above-ground pools, while others perform best in in-ground pools. Choosing the correct model ensures optimal cleaning performance.

Pool Size

Manufacturers recommend maximum pool lengths for each cleaner. Selecting a robot that’s too small for your pool can result in incomplete cleaning and longer cleaning times.

Cleaning Coverage

Basic models clean only the pool floor, while advanced robots also scrub walls, waterlines, and steps. If your pool collects algae or dirt along the walls, choose a model with full cleaning coverage.

Filtration System

A high-quality filter basket helps remove leaves, insects, sand, pollen, and fine dust. Some premium models include interchangeable filters for different types of debris.

Smart Features

Wi-Fi connectivity, mobile app control, programmable schedules, and intelligent navigation add convenience but usually increase the overall price.

Corded vs. Cordless

Corded robotic cleaners provide unlimited runtime and are suitable for large pools. Cordless models offer greater flexibility but require battery recharging between cleaning sessions.

Warranty and Support

A robotic pool cleaner is a significant investment. Choose a manufacturer with a strong reputation, reliable customer support, and a solid warranty.
