FEATURES

POOL TYPE AND SURFACE– The best thing to know about Polaris Vac-Sweep 3900 is that it can clean in-ground pools of all shapes and sizes. The pool cleaner can clean large to small pools. It is best suited for small pools due to the size of the pool cleaner as it can clean the pool faster. The pool cleaner also works in large pools but will take some time due to the extent of the pool. But let it be small or large pools, the cleaning efficiency of the pool cleaner will not change. Polaris Vac-Sweep 3900 can clean any pool surface including vinyl and fiberglass and also works in flat or sloped surface. 

SET-UP – Polaris Vac-Sweep 3900 requires the use of a booster pump. The pump doesn’t come with the pool cleaner and has to be purchased separately. A 31-feet long feed hose has been provided with the package. The feed hose comes in black colour and fits a 1.5-inch connection. The pool cleaner comes ready to attach to the in-ground pool’s return line. Connecting the required cables to the pool cleaner is fast and easy and doesn’t consume much time. The 31 feet long feed hose is heavy-duty and if the user wants to cut the feed hose to suit their pool size can also do so. The long hose provides complete freedom to the pool cleaner to move around underwater up to 25 feet. 

POWERFUL VACUUM – In a pool cleaner the most important aspect is the vacuum power. A strong vacuum power can clean the pool better and swifter. So, don’t underestimate Polaris Vac-Sweep 3900 pool cleaner due to its size as it contains powerful vacuum power. In order to receive maximum benefit from the pool cleaner, use it with Polaris’s booster pump. The booster pump revs up the water pressure enabling the pool cleaner to move efficiently. Polaris 3900 uses three Venturi style jets to build up the filtering power to 40 GPM. The pool cleaner consists of an extra-large 2.5-inch inlet in order to collect everything from leaves to minute debris. Polaris 3900 consists of three propulsion jets to amplify the cleaning performance. All these attributes contribute in making Polaris 3900 a reliable pool cleaner meant for high-end pool cleaning.

AUTOMATIC THRUSTING BACKUP VALVE – Sometimes even a well-designed pool cleaner finds itself stuck. Hence, Polaris fused a backup valve into the Vac-Sweep 3900 pool cleaner. The in-line valve automatically directs the waterflow through the valve instead of passing through the pool cleaner. This provides the pool cleaner the necessary thrust to back up and change course. Polaris 3900 is fully equipped to back itself up without needing user’s interference. In this way the users can be rest assured without bothering about the pool cleaner.

TAILSWEEP PRO – Polaris 3900 is probably the first pressure side pool cleaner to have TailSweep PRO as their standard feature. Some people may guess that Polaris 3900 can’t clean all four corners of the pool or sloped surfaces because of its design or shape. Polaris may have an awkward design but in spite of the shape, the pool cleaner is capable of cleaning each and every of the corner of the pool due to the TailSweep PRO feature. The feature consists of a scrubber/hose combs that ejects high pressure jets of water at the pool corners in order to smoothen the accumulated debris so that the vacuum can scoop it all inside. Additionally, it makes sure that the water doesn’t splashes outside the pool which is an impressive trait of Polaris 3900. The pool corners are the trickiest areas as it’s the place where the toughest debris reside and the TailSweep PRO feature really does a great job of removing the junk to make the pool look spotlessly clean.

DUAL CHAMBER FILTER BAG – Aren’t you tired of cleaning the filter bag after every cleaning session? Well, Polaris 3900 is here for your rescue as it comes with a humongous 5-litre debris capacity. The debris bag comes in zipper style and after opening you will find twin chambers that are meant for two different types of debris- large and small. 5-litre debris capacity is a pretty big size for a pressure side cleaner to possess. The zipper accessible bag holds a large amount and is quick to empty out. The pauses between the cleaning time are reduced and also the time spent cleaning the bag also decreases. This zipper setup extends the lifespan of the bag and reduces the need of buying replacements. 

POSITRAIN SYSTEM – The PosiTrain system is a newly designed all-wheel drive train that offers maximum torque as the pool cleaner cleans the pool. The pool cleaner goes around on three wheels that are operated by hydraulics that gets hold of the water from the booster pump to spin the wheels. There’s no need to get concerned about the chain connecting the wheels and the gearbox as it is made of stainless steel to resist corrosion throughout the pool cleaner’s lifetime. 

WIDE TRAX WHEELS – Polaris 3900 is packed with efficient features to make pool cleaning better and swifter without any hassle. The Wide Trax Wheels of Polaris Vac-Sweep 3900 are smooth and provides stability to the pool cleaner. The wheels are smooth and won’t leave any marks on the pool surface and they won’t rip the pool liner. Even though being gentle on the pool surface the wheels are strong enough to provide the necessary traction and steadiness to climb the walls and rails while cleaning. 

NAVIGATION – Polaris 3900 provides random yet effective navigation while pool cleaning. The Wide Trax wheels allows the pool cleaner to roam freely around the pool. The pool cleaner moves randomly around the pool and scrubs accordingly to efficiently remove all the existing debris from the pool surface. Polaris 3900 is programmed to back up and move few steps back if it gets stuck or encounters any sort of obstacles while cleaning. The pool cleaner frees itself and then continues its cleaning job. 

SAFE AND EFFICIENT – Polaris Vac-Sweep 3900 is safe for use on all pool surfaces. It also works great in chlorine and saltwater systems. Due to the compact shape of the pool cleaner, it can be conveniently stored. 

WARRANTY – Polaris 3900 includes a five-year warranty that is applicable only to the frame while the rest of the parts are covered by a one-year limited warranty.
