"A disposable robot offering freedom from hoses at a hose-cleaner price."
A 'cordless robotic cleaner' at this price means a battery-powered unit that randomly wanders your pool floor. It is 'robotic' only in that it moves on its own; it possesses no intelligent mapping and its effectiveness is limited to light debris on a simple, flat surface.
This is for the owner of a small, flat-bottom, above-ground pool aiming to replace a manual vacuum or cheap suction-side cleaner. It offers a taste of cordless convenience for light debris, provided expectations for durability are set extremely low.
Anyone with an in-ground pool, a pool with a sloped bottom, or significant leaf and dirt load should avoid this. Buyers seeking a multi-season investment will find better value in entry-level corded models from established pool cleaner brands.
