In the grand scheme of things it really wasn’t that long ago when all pool cleaning and maintenance tasks were accomplished by rolling up one’s sleeves and doing them manually by hand. This required a long aluminum pole that had a hose and a broom attached to the far end. A hose that ran from the broom to the pump to suck the water up, and run it through the filter. But then about five decades back the automatic pool filter appeared on the market.
That was five decades back though, and since that time quite a number of improvements have been made on this popular labor saving device. So now there are there more features and options in these machines that do a much better job of keeping the water in the pool sparkling clean. Also as a result of the decades long ongoing efforts to create an even better under-water vacuuming machine you also now have a total of three different overall types to select from.
Starting from the bottom of the list of three types, you have what’s commonly referred to as “pressure side” pool cleaners. These tend to have the least moving parts, be the least problematic, and also be the most affordable. At the same time though, pressure side models are for low-volume situations. They’re powered by a hose that’s connected at one end to a water out-port, and the other into the machine, and because the water is “pushed” through them they’re called pressure side.
Next up on the list of three, is the similar functioning models known as “suction side” swimming pool vacuums. This class has a few more moving parts, they’ll the cost a bit more than similar size and capacity pressure side models, but they also do a better job of cleaning. They’re powered the same way as above listed pressure sides, with one difference. That is that instead of being hooked up to the out port, the hose is hooked up to a water intake port to suck water through the machine to run it.
Then number three on this list, is what is known as the “mechanical” automatic pool cleaner, and it is by far the most expensive. It is however, the most feature laden, and instead of being powered by a water hose this class of water vacuum contains an electric motor that can be ran from a cord or rechargeable batteries. Mechanical models contain rotating scrubbing brushes, so they’re mainly designed for use in concrete pools.
What type of pool that you have, and it’s size will determine the type and size of automatic swimming pool cleaner that you’ll need. Affordable pressure side automatic pool cleaners for instance are primarily meant for smaller above-ground pools that don’t have major debris rounds. A suction side model would be called for in a larger above-ground pool or a smaller in-ground. Then for cleaning the cement walls of the classic built-in, a robotic model is recommended.
