Algae are very dangerous for your pool because it can make the floor slippery. This increases the risk of a possible injury. To flourish, algae require sunlight. By preventing exposure to sunlight, you prevent the pool from being inhabited by fungal growth. Although a pool cleaner will keep your pool clean and get rid of algae, you want to minimize your work by preventing the algae from growing in the first place.
It is still important to have a liner for in-ground pools because these pools are still susceptible to damage. Liners can also protect from algae and other surface contaminants and the designs can offer a fun change from the bare look of your pool.

Hold the cleaner off the bottom of the rebotic pool cleaners and observe, the cleaner should: pool cleaner rotate right - not rotate - rotate left - not rotate - rotate right - etc. All the time, the "pods" should be kicking.

Pressure cleaners push water to the cleaner, propelling it along the pool floor and occasionally up the walls. The pool is cleaned by the venturi vacuum the pressured water creates. The venturi effect forces leaves and debris up into a catch bag, net or screen. In addition to collecting leaves, sticks, etc., a tail is present to "scrub" the floor. This little tail is very underrated! In fact, the tail is one of the major advantages.
