Factory Pools - Pool Cleaners
It’s important to clean your pool regularly-not just to enhance its appearance and sanitation level, but to protect the quality of your investment.
Have a look and see what is right for you.
In this type, water pumped out of the pool via its skimmer or drains is used for locomotion and debris suction and returned after being filtered via pool return or outlet valves. This is the least expensive and most popular type. It traces a random course. This type of cleaner is usually attached via a 1.5 inch hose to a vacuum plate in the skimmer, or to a dedicated extraction or "vac" line on the side of the pool. The suction action of the pool's pump provides motive force to the machine to randomly traverse the floor and walls of the pool, extracting dirt and debris in its path. The first automatic pool cleaner was a suction cleaner.
These are the least expensive and most widely used pool cleaners with purchase costs ranging in the $300–$1000 price range. They are powered solely by the main pump of the pool and utilize the pool's filter system to remove dirt and debris from the water. These machines effectively diminish the suction of the main pump - using them will increase the electricity costs and require the main pump and filter system to be serviced more frequently. There is minimal maintenance and part replacement costs on these devices over time.
These cleaners are independent from the pool's main filter and pump system and are powered by a separate low voltage electricity source, usually in the form of a set-down transformer that is kept at least 3.0 m from the water in the pool, often on the pool deck. They have two internal motors: one to suck in water through a self-contained filter bag and then return the filtered water at a high rate of speed back into the pool water. The second is a drive motor that is connected to tractor-like rubber or synthetic tracks and "brushes" connected by rubber or plastic bands via a metal shaft. The brushes, resembling paint rollers, are located on the front and back of the machine and help remove contaminating particles from the pool's floor, walls (and in some designs even the pool steps) depending on size and configuration. They also direct the particles into the internal cartridge filter or filter bag.
An internal microchip is pre-programmed to turn on and off and reverse the direction of the drive motors. The chip will cause the machine to change direction when it reaches a wall or the water surface after climbing the pool walls.
These machines may also be directed by sensors located in the bump bars which, on contact with objects such as a wall, cause a reverse in direction, with a small offset allowing it to move one machine's width over on each crossing of the pool. The delay timer is an important feature for many pools, as many switch off a number of circulation pumps during the night to allow suspended particles to settle on the bottom of the pool; after a couple of hours the pool cleaner begins its cleaning cycle. This cleaning cycle is set up to complete before the pumps are turned back on. though not necessary for adequate pool cleaning, this feature saves energy and improves cleaning efficiency.
In order to move forward and backward and negotiate walls and steps electric robotic cleaners rely on three natural principals, traction and movement caused by the drive motor and tracks, buoyancy created by the large areas inside the machine that fills with air, and the force resulting from the high pressure of water being emitted from the top of the machine that pushes it against the floor and walls. Some electric robotic machines use brushes made out of polyvinyl alcohol (PVA) Polyvinyl alcohol that has an adherence quality that allows the unit to almost cling to the walls, steps and floors. They also are resistant to dirt and oil improving lifespan over rubber or other synthetic materials.
The combination of these three natural principles along with an internal mercury switch that
tells the microchip that the unit has gone from a horizontal to vertical position as it climbs a
wall allows it to change direction from ascending to descending the wall at pre-programmed
intervals based on the average height of a pool walls. Some machines have delayed timers
that cause the robot to remain at the water line, where more dirt accumulates, for
momentarily resulting in a scrubbing action, much like the wheels of a powerful automobile
spinning or peeling out.
The major benefits of these machines are efficiency in time, energy, and cleaning ability as
well as low maintenance requirements and costs. The major disadvantage is purchase cost
which can range from $1200 for floor-cleaning-only machines to over $4,000 for the most
sophisticated residential units. Our biggest selling model the Maytronics Dolphin S150 robotic cleaner is $1300 when
you purchase a pool.
