Polaris Vac-Sweep 3900 Sport Pressure Side Pool Cleaner

I have to say without a doubt this is one of my better purchases. My old pool vac was not getting the job done and I needed something that woud. I have a theory that I will be sorry if I go cheap, yet I don't want to pay too much. This pool Vac was a clinch to install and get it running as designed. I have had now for almost a year and I am still amazed at how well it cleans. Could not be happier.

8For 30 years I used and maintained an Arneson Pool Sweep until March of this year. Parts being impossible to find and no one alive that knew how to repair them, I finally decided to cough up the big bucks and make a change. After speaking to a technical friend, with a pool, asking what he used, he said for the last 3 years he had used a 3900 Sport with no problems. Researching Amazons reviews, I was alarmed by many of the responses. So I called Polaris' Bonnie Shaw directly at 760.230.2424 and asked her about these reviews. She informed me that when this product came out there were some technical problems that were addressed and fixed and that new units were performing as advertised. She assured me that I should have no problems as long as the current model was used. On her recommendation, and that I my friend, I purchased and installed the new unit and within 3 hours my pool was spotless and the unit worked as represented. I have a large 35,000 gallon pool in the configuration of an offset figure eight, the shallow end being shallow enough for most 5 year olds to be above water, and the diving end being 9.5 feet deep. I followed the instructions on cutting lines and measuring rotations. NO Problems and easy to do. The only adjustment I need to make is in the tail which does not sweep. I have not been able to do the complete adjustment yet, due to the temperature and rain in our area over the past few weekends. No matter, It still cleans everything but some narrow steps. To date, I am thrilled and would buy this again and will recommend it to anyone. I am over 70 and have arthritis in my back and knees and if I can do this, anyone can do this. At this point I believe that most of the bad reviews are from people who didn't read and/or use the instructions properly, or are from misleading competing products. As time goes on, I will comment on my own review, if any problems occur or if the status quo is maintained. **UPDATE ** 3 years later,, Everything running at normal...P00l spotless and the only thing I have done is replace the bag when a stick was picked up and tore the bag. I also replaced the sponge end. I can't recommend a product enough. Old Tex

My first Polaris was constantly spraying our windows. Not this one !!! It does the job but not the windows. Since that earlier review, I now find that it gets stuck by the steps and is eroding my pebbletech pool finish. I'm not sure why this is, but if it can't be fixed, I will have wasted over $800.00. Any ideas on this? New tire rubber, hell its only three months old! Arggg!! So I was fortunate to have Prime and as such I was able to return this inferior product and receive a refund. I purchased a Dolphin Quantum Pool cleaner by Maytronics about six weeks ago and couldn’t be happier, ( see that review ). Yes it’s $200.00 more, but without the noise and it is a serious upgrade above the Polaris ( Junk )!!! You get what you pay for !! The only problem with the Quantum was the cord getting wrapped and tangled. I ordered an upgraded cord that had a swivel which eliminated the tangles. Don’t order a Polaris, but do consider it Quantum. Great cleaner by Dolphin Industries.

This is our second one to own. Does a great job! I would say 'would buy again' but I already did that.

The Polaris 3900 does a great job cleaning your pool. Right out of the box, 5 minutes to fully operational. We got the "black" version. The hose is soft and flexible making it very easy for the unit to move around, and the tail sweep performs just like it has for 30+ years in the model line. Comapred to the older 280 & 380 models, the 3900 has the 3 vinturi jets of the 380, but adds a dual chamber bag, larger wheels, and a streamlined shape that makes it easier for the unit to move through the water. We also noticed that it seems to move noticably faster than our old 280. The 3900's wheels are a bit ridiculous, they look comically large and they are a lot closer together than the old 280 and 380 frame. However the benefits of the larger diameter include smoother motion across the floor, and they are easier to get over bumps like floor drains that tended to catch the 280 and 380 models. Overall it's a huge improvement on the older models, and depending on desires for automated cleaning, well worth the cost.

So I wanted to write this review after seeing all the negative comments about this Polaris and I also wanted to wait a week to give my impressions of the 3900. The first thing I noticed after pulling it from the box is the quality of the parts. The Polaris appears to be very well built and I like the durable stainless steel drive. I’ve checked my pool everyday and everyday it has been completely clear of debris. My old Polaris would constantly get stuck or I had to untangle the rope, it also left debris in certain areas every time. The only time I touched the Polaris this week was to empty the bag. This Polaris also seems faster than my old one. My wife was against buying this Polaris because of the bad reviews but I insisted on giving it a try. I am very pleased with the 3900 and would say the only con is the price.

I purchased a Polaris 3900 August 2017 for my new house. There was a problem for close to a year- the cleaner was sluggish, constantly getting stuck, back up valve did nothing, tail didn't sweep. All these issues were day 1, right out of the box. I hated this thing and was ready to rate it a ONE STAR and ship it back to Polaris. After hours spent troubleshooting, purchasing a new pump (another $400!), returning to pool store for warranty repair etc etc etc, a lot of online research, i finally tried a replacement quick disconnect, and BRAVO it works perfectly now. It was caused by a defective pressure relief valve in the quick disconnect, which in hindsight should have been obvious because the original pressure valve was discharging too much water at the disconnect when operating. The new one discharges no water and enables the pressure to go to the wheels, tail sweep and backup valve. The thing works like a charm now!! If you are having the same problems with sluggish performance, spend less than $15 and get a new quick disconnect with pressure relief valve. I hope this helps others. Try it. Now the Polaris Vac-Sweep 3900 is great. By the way Polaris customer service is excellent.

I had this for less than a month. Worked great then wheels locked up. I had old one for 12 years. Never a problem. I gave it 3 stars because previous one worked very well. Also arranged for Pick up on Saturday still waiting for pick up.

C’est le 5ieme en 10 ans…fonctionne bien mais s’use les rouages internes s’usent et la vanne régulatrice de surpression se casse…un construction plus solide serait la bien venue
