The Polaris Vac-Sweep 3900 Sport is one of the best pool cleaners (opens in new tab) for ridding your pool of large objects. That’s because the 3900 pressure-side in-ground pool cleaner comes with a large inlet and has one of the strongest vacuuming power.
You could say that it’s because of these features, the Polaris Vac-Sweep 3900 Sport is one of the more expensive pressure-side devices that we’ve reviewed. It works out at around $900, but that’s if you already have a booster pump, as this powerful three-jetted machine requires a booster pump to work
If you don’t already have a booster pump, a Polaris pump (which of course the brand claims is most compatible with its range of pool cleaners) will set you back around $300. If you’d rather a model that has a booster pump, head over to our Polaris Vac-Sweep 360 review (opens in new tab).
Polaris Vac-Sweep 3900 Sport: Features
The Polaris Vac-Sweep 3900 Sport has a large debris collector bag, which makes this pool cleaner ideal if you have a huge capacity of debris to collect. It means it can also go longer without having to change the bag. Although the brand suggests that this should be changed when it gets half full.
The Polaris comes with an automatic backup valve to stop the device from getting stuck in one place for too long. This also ensures that no areas of dirt are missed.
This pool cleaner also comes with the added extra of a ‘TailSweep Pro’. This is the brand’s signature sweep hose that helps to stop water from spraying out of the pool whilst the machine is cleaning it. It also helps to get any dirt out of corners by swooshing them away.
Polaris Vac-Sweep 3900 Sport: Design
Unlike the Polaris Vac-Sweep 360 (opens in new tab), which is a smaller design to the Polaris Vac-Sweep 3900 Sport, this version is designed to work through the use of a booster pump. This is common with most pressure-side pool cleaners, although a select few don’t require this piece of kit.
However, this pressure-side pool cleaner works by being hooked up to a booster pump. The booster pump helps to give optimum power to all Polaris pressure-side pool cleaners.
Polaris Vac-Sweep 3900 Sport: Performance
The Polaris Vac-Sweep 3900 Sport is one of the highest performing pool cleaners and it has the stats to back it up. The 3900 Sport can suck up to 40-GPM through its unique filter bag which has dual chambers. Plus its debris collector bag has a five-liter capacity. This makes your job even easier, with less disposing of waste to do.
According to the brand’s website, the 3900 Sport has 50% more traction thanks to its three ‘Wide Trax’ wheels. Its inlet is also 2 ½ inches wide, meaning no rock, pebble, or piece of debris is too big for this contraption.
Polaris Vac-Sweep 3900 Sport: User reviews
The Polaris Vac-Sweep 3900 Sport averages a 4.2 out of five from just over 400 reviews on Amazon.
Many users who have bought the Polaris Vac-Sweep 3900 Sport have praised the pool cleaner for leaving their pool debris free. One user came back to write a review three years later claiming everything is still ‘running as normal’ and the 3900 Sport has left their pool ‘spotless’. Whilst other plus points about the pool cleaner include the fact it can clean steps, ridges, and nooks even in the deep end. The large debris bags were also praised for being very easy to clean themselves.
However, the pool cleaner lost stars for the lack of its sweeping tail. One user said that after a year of pool visits from a pool maintenance company, the mystery as to why it won’t work properly still hasn’t been solved. Whilst another slated the Polaris Vac-Sweep 3900 Sport for not being able to work in curved pools.
Should you buy the Polaris Vac-Sweep 3900 Sport?
If your pool is situated near trees, areas of rock or pebbles, the Polaris Vac-Sweep 3900 Sport may well be the best pool cleaner for you. Its super vacuuming power means no stones are left unturned (quite literally). Whilst its wide throat inlet means it can suck up large stones or any other debris that finds its way into the pool.
This machine doesn’t come with a booster pump and is already priced towards the higher end of the going rate. Having to pay for an extra booster pump will increase the price even more so.
