Buying Guide

Pool type compatibility

Confirm the cleaner supports your pool type—many under $100 are optimized for above-ground or flat-bottom pools, while some list in-ground compatibility

Power and runtime

Look for cordless models with sufficient runtime (examples in this set report up to 100 minutes) and clear charging specs to match your cleaning schedule

Drive and cleaning system

Dual-drive or dual-motor systems offer better traction and maneuvering on larger surfaces; simpler single-drive units may be fine for small, flat-bottom pools

Filtration and debris handling

Check filter type and access—easy-to-remove cartridges or baskets speed maintenance and are common on budget robotic cleaners

Durability and weather protection

Consider weather-resistant accessories or covers and build quality—separate caddy covers and weather-resistant tags indicate attention to outdoor durability
