Please note that no matter how good the automation and chemical control of a pool, some form of regular brushing is required!  A pool sweep or robot is a good way of doing this. 

By keeping the pool clean, Pool Sweeps and Robots minimise dirt, abrasive materials and algae growth on the surface finish.  The combination of cleanliness and correct chemical balance are important not only to the ambience and health of your pool but also to getting a long life from the surface finish of the pool. 

Tiles and Pebblecrete are usually durable finishes and are not much affected by automatic pool cleaners.  Rough Pebblecrete, can however prematurely wear out the wheels on pool sweeps. Epoxy paints are a good surface finish, but, unlike other surfaces, they are deliberately self-ablating.  That is, the surface constantly renews itself by continuously shedding the surface layer of paint.  This is why it retains its freshness and colour so well.   Successive layers turn slowly into a whitish powder and this has to be removed.  Pool sweeps do this well in most cases, scrubbing the particles into the water where the filter removes them.  This is a slow process with epoxy paint finishes typically lasting many years.  Using a pool sweep will help keep this (and most other) surfaces looking good.

Pool sweeps should not be over-used as there is little benefit to cleanliness in running extra hours each day.  Moreover, such extra use consumes electricity and reduces the lifetime of the pool cleaner and the pool finish.  Pooled Energy sets recommended hours per day for the type of cleaner you have and varies this with the weather, for example, potentially providing extra sweeping time after windy weather.  You may vary the cleaner sweep settings using the Pool App if you need extra or fewer cleaning hours.  These usually depend on the trees and wind in your area, and your particular pool.

Some pool sweeps have hard wheels that do wear out paint surfaces faster than those with softer wheels, and you may wish to consider this when purchasing a pool sweep. It is important to trim the sweep hose to the correct length so that the sweep doesn’t get stuck in a corner where it is likely to eventually damage  paint or fibreglass surfaces.  Pool Cleaners tend to get stuck when the hose is too long. If it is too short, the Cleaner may not be able to reach into a corner.
