Compatibility / Fitment Notes
Maytronics lists this cleaner for in-ground and above-ground residential pools up to 50 feet long. Listed surfaces include liner, gunite, fiberglass, tile, ceramic, mosaic, glass, and stainless steel. Surface listing does not replace checking the condition and layout of your individual pool.
Confirm the longest pool dimension and the depth of any shelf you expect the cleaner to reach. The shallow-ledge claim starts at 8 inches, so a shallower shelf should not be assumed compatible. Describe narrow steps, benches, unusual corners, and changes in depth when asking for selection help.
Match the full model name and part number 99994410-US before purchase. EON models have different filtration and warranty specifications; treat accessories and replacement filters as model-specific until their fit has been verified.
Installation / Use Notes
Read the Maytronics user instructions before first use and follow the supplied charging and setup guidance. Use the Maytronics One app with the robot out of the water. After cleaning, rinse the filter and follow the manufacturer's care instructions.
A practical buying check is to decide where you will charge and store the cleaner and how you will reach it for routine filter care. Those handling details matter when comparing cordless equipment, especially if the pool edge or storage area is difficult to access.
