Buying Guide: What to Look for in a Cordless Pool Cleaner
Battery Life and Runtime
The biggest advantage of cordless cleaners is freedom from cords, but battery life determines how much of your pool gets cleaned. For inground pools up to 40 to 50 feet, look for at least 2.5 hours of runtime. Models like the Dolphin Nautilus EON 100 offer 2.5 hours, while the Niya Sonar 60 stretches to 5 hours. If your pool is smaller, a 1.5-hour runtime (like the Niya Sonar 20) may suffice.
Wall Climbing and Waterline Scrubbing
A cordless cleaner that only cleans the floor leaves a lot of dirt behind. For a truly clean pool, choose a model that climbs walls and scrubs the waterline. The Dolphin Nautilus EON 100 and Wybot C2 both excel at wall climbing, while the Niya Sonar 60 boasts waterline cleaning even in shallow areas. If your pool has steps or sun ledges, ensure the robot can handle those too.
Navigation and Smart Features
Smart navigation saves time and ensures thorough coverage. Look for models with gyroscopic or sonar-based mapping. The Niya Sonar 60 uses sonar to avoid obstacles and park itself for easy retrieval. The Dolphin Nautilus EON 100 offers Wi-Fi app control for scheduling and mode selection. For those who prefer simplicity, the Dolphin Escape uses SmartNav 2.0 for efficient path planning.
If you are considering other cordless options, our best WYBOT cordless cleaner for inground pools in 2026 guide provides additional insights.
Filter System and Maintenance
A top-load filter basket makes cleaning the robot a breeze. No flipping the unit over or removing wet debris from the bottom. The Dolphin Nautilus EON 100 and Dolphin Escape both feature large, top-load cartridges. The Wybot C2 uses a dual filtration system (10μm and 180μm) for fine particles. Consider how easy it is to rinse and replace the filter, you will do it after every cycle.
For above-ground pools, top-load filters are especially convenient. See our best above ground pool cleaner with top load filter in 2026 for more recommendations.

For most inground pools up to 50 feet, the Dolphin Nautilus EON 100 Cordless Robotic Pool delivers exceptional battery life, wall climbing, and Wi-Fi convenience.
