The Polaris 3900 Sport is the most advanced model in the Polaris Vac-Sweep pressure-side pool cleaner series. Is it better than the cheaper Vac-Sweep models?
Our Polaris 3900 review considers its features and specifications. We also consider its various components and compare it to the Vac-Sweep 380. We might discover whether or not it is the best Polaris pressure pool cleaner.
Polaris 3900 Sport: Summary
The Polaris Vac-Sweep 3900 looks a little different than the other Vac-Sweep pool cleaners, but it still works on the same principles.
The Polaris 3900 Sport needs extra water pressure to clean effectively, therefore the installation of a booster pump is essential for its operation. Polaris Vac-Sweep pressure-side pool cleaners require a booster pump, except for the Vac-Sweep 360 which only needs water pressure from the pool pump’s pressure return line. These pool cleaners work by hydraulic power.
The 3900 Sport has three wheels which are connected to its gearbox with a stainless steel chain. The chain transfers power from the gearbox to the wheels. The gearbox is powered by water pressure from the booster pump.
It has a dual chamber debris bag which captures more dirt so you do not have to clean it as often. The water passing through the filter bag gets filtrated at a rate of about 40 gallons per minute.
The Tailsweep Pro is a standard accessory with the Polaris 3900 Sport. The other pressure-side models have the ordinary tail sweep. The Tailsweep Pro sweeps the pool bottom and corners while reducing the chance of water spraying outside the pool. This way the the tail sweeper washes the pool surfaces and not the windows.
If the Polaris 3900 gets stuck against an obstacle, it will eventually reverse itself and continue cleaning.
Inground Pools Only
The Polaris 3900 Sport cleans inground swimming pools. It can work with all pool surface types. It cannot be used for above ground pools.
Powered By Booster Pump
The PB4-60 booster pump is recommended for the Polaris pressure-side pool cleaners. It costs around $400, but you might get it cheaper at Amazon.com. The PB4-60 has a 3/4-horsepower, 60-Hertz motor. A length of hose and and a few quick connectors are usually included with the booster pump. You can install it yourself if you have some basic plumbing and mechanical skills.
The three wheels of the pool cleaner are driven by hydraulic power which is provided by water pressure from the booster pump. A stainless steel chain links the wheels and the gearbox system. The wheels have black Widetrax tires which provide wider traction. The tires wear out with regular use and eventually need replacement.
Dual Chamber Debris Bag
The Polaris 3900 Sport has a large, 5-liter capacity, dual chamber debris bag with zippers. The dirt and stuff from the pool is sucked into the bag by the vortex jet action. The double debris bag increases the time between bag maintenance. The zippers on the bag might be a problem if debris get stuck between the teeth. You will probably replace the bag once per year.
Sweeping Scrubbing Tail
The pool cleaner drags a water pressure sweep hose with a Tailsweep Pro attachment behind it. The tail sweeper has a brush to sweep surfaces. It also blows debris out of tight corners without blowing a stream of water out of the swimming pool.
What components are included?
Let us give you a list of components included in the box:
- 31-foot feed hose
- back-up valve
- feed hose connector
- hose floats
- in-line filter
- pool cleaner body
- quick disconnect universal wall fitting
- restrictor disks
- superbag double debris bag with zippers
- sweep hose
- Tailsweep Pro
The Polaris 3900 Sport/P39 owner’s manual is also included in the box.
Is it available in white?
We do not think so. The Polaris 3900 Sport is only available in the black, grey and blue color scheme. It will look at its best in pools with a dark bottom and dark walls. If you have a whitish or lightly colored swimming pool, then you might want to consider the Vac-Sweep 380 which has a white and blue color scheme.
Polaris 3900 Sport Vs. Vac-Sweep 380
There are many similarities between these two pressure-side pool cleaners because they belong to the same series of Polaris Vac-Sweep cleaners.
First of all, they both have three Venturi jets. They both require the same booster pump and they can only be used for inground pools. The automatic back-up valve is found on both cleaners.
Nevertheless, the Polaris 3900 Sport has been updated with a slightly larger 2-1/2-inch vacuum inlet. It also has the stainless steel chain drive system while the Polaris Vac-Sweep 380 has a belt drive system. The tires on the 3900 are wider than the tires on the 380 and therefore providing better traction.
The Polaris 3900 has a dual chamber filter bag while the 380 has a single chamber debris bag. The 3900 also has the Tailsweep Pro sweep hose brush system as a standard feature.
The Polaris 380 has a standard Tailsweep attachment. The 380 model is compatible with the Tailsweep Pro, but you need to buy it separately and then install it yourself.
Polaris 3900: Good Sport or Bad Spot?
We have come across a few very negative reviews concerning the Vac-Sweep 3900 that make it look like a bad apple. It seems that the first generation units suffered from a few teething problems. However, this was a few years ago and the newer generation units seem to be working according to specifications.
The Polaris 3900 now seems to be a good sport in the swimming pool. Current owners are satisfied with its cleaning performance. Still, you need to take the time to set it up properly according to the instructions in the manual. This is not difficult to do, but it might require some trial and error.
Basic plumbing skills and tools might be necessary to install the booster pump. You can hire a plumber to install the booster pump if you do not have the skills to do it yourself.
|The Polaris 3900 Sport costs a a few hundred dollars more than the Polaris 280 or 380, yet it does not seem to perform better than the previous models. We would probably save some money and buy one of the older Vac-Sweep pool cleaners. Nonetheless, the 3900 Sport is more powerful and it has a larger capacity for debris. You may buy it online at a competitive price at Amazon.com.|
