VINGLIAutomatic Pool Vacuum Cleaner Swimming Pool Vacuum with Additional Hoses & Diaphragms (Grey)

I bought this product because we have a 35 year old fiberglass in-ground pool and I wanted something which would clean without leaving tread marks or wheel marks on the walls. This product takes some learning-time to balance flow rate and suction to enable it to operate well. But, once you have it down, it is pretty easy to manage. HOWEVER, it will "blow itself apart" if your pump pressure is too high. I was not going to purchase a $600 adjustable rate pump so I solved the problem another way.I slipped a large, flat, thin rubber washer around the suction end of the yellow suction tube. It cost about $0.10 but was free to me since I had two in my washers collection. Works great. Sweeps my whole pool in about 8 hours. And, continues to be gentle to my pool's aging finish.

The new blue model has no convenient carrying handle on top anymore, and is thus necessarily somewhat shorter as a result. Insides seem similar. However, still the best value on the market. I broke the last one with the handle, when I put in a new diaphragm and the entire assembly including the hose shuttered violently. I forgot to turn down the pressure on the regulator and I quite literally broke the frame of the old one. You need to adjust the regulator with a new diaphragm until the device just putt-lutts along. As the diaphragm ages, the gap usually gets wider, requiring a more forceful pressure from the regulator to operate properly. A new diaphragm should have the lips either touching or at most about 1/16" separated. One recent diaphragm replacement shipment had the diaphragms with a 3/8"+ separation - completely useless since my old one had about a 1/8" separation and was hardly performing at all. I have a 3/4HP pump and about 12,000 gallon pool. Comes with two diaphragm replacements - all with either closed or less than 1/16" lip separations. I like the 90o pressure regulator - the ones with a straight regulator would be impossible to implement in my pool configuration. Trouble shooting the Vingli is pretty straight forward. Check the pressure drop across the water filter. In my pool and Hayward sand filter, a 6-8psi filter drop is fine; above 12 psi and a back washing is needed. If that doesn't work, bring the beast to the surface and look down the throat. You may have a rock or leaves clogging up the diaphragm. If that is clear, unscrew the tube and pull out the diaphragm. Several times fatigue had created a hole in the side, thus bypassing the lips and creating no putt-putt suction. Have never had the sides split, but have seen it in others. Then check for bubbles in the water return. This can be caused by a hole in the suction line - rubbing the side of the pool is very abrasive, and check the hose piece connections - make sure they're tight. Also relube the pump strainer O-ring and tighten accordingly. That's about it. Vingli's are very simple to use, operate, and trouble shoot.

Ok, so it’s not the most incredibly built vacuum but it works. Comes with two diagrams so your gonna get at least 6-8 months out of each diaphragm. We’re around 4 months on diaphragm 1. Still going.The later timeline is if your pool is covered and no debris gets stuck in the diaphragm regularly. If it’s eating leaves daily this is a terrible vac for you as it will just always be jammed.It gets stuck on my steps but eventually gets free. We removed the ring and it helps tremendously with it staying free. Build quality is cheap and it’s all scratched up from rubbing said steps , but again, working.I’m running a larger pump. We had a big mechanical vac for years that needed big suction. So this little vac climbs the walls without issue and I’m turned down a bit on suction but that will depend on your pump size. It scoots around our pool very well and we have pump return jets alternating sides so it gets moved around very well. (If you don’t have strong jets you need a mechanical that tracks directions or this vac will just go over the same spots repeatedly). I run the pump 6 hour a day currently but usually we get up to 8 by mid summer with the kids using it daily.Set up and install are easy. I used our existing hose because I’m lazy. Got lucky and they fit well enough a little bike inner tube rubber gasket was just about perfect.So why buy this cheap vac and not the $$$ version or a mechanical cleaner? Because it’s $100. If it last a year I can buy six of them for the cost of one mechanical vac that will last about 5-6 years(maybe because everything is cheap now. Sad but true). Maybe we get lucky and get 1.5 years out of a couple of them and I’ll come out with an extra year or two on the same money.Haven’t tried to buy diaphragms yet but that will also extend the lifespan.So basically, I’m going with the certain thing here. Assuming it’s all cheap, buy it cheap.Time to roll those dice! 🫣
