Equipped with patented SmartDrive® technology, the Wanda the Whale Cleaner from Hayward is designed to automatically clean the bottom of all sizes and shapes of above-ground and on-ground pools quickly and completely—making sure no debris is left behind. It operates separately from your pool’s filtration system and connects directly to your skimmer, installing in less than 10 minutes without tools. A unique turbine system helps Wanda the Whale move gently across the bottom of your pool, providing exceptionally quiet performance while improving circulation by pulling water up from the bottom of the pool as it moves.

This is the 3rd year of Wanda and I am very happy with her. Pros: keeps pool clean with minimal effort on my part. Picks up more than my push vaccum head. Helps keep pool water warmer by circulating the cooler bottom water with the warmer water on top (in combo with solar cover). Can be used with solar cover on. Easy to take apart to replace parts/remove rocks or other stuck items. Cons: She sometimes gets stuck in place. I just pick her up and move her and shes fine. it doesn't happen often and is not even really a con. It's a more affordable machine so I do not expect it to be running like a thousand dollar vaccum. IMO, she is worth every penny. When she finally gives out I will but another one.

***Update: Don’t make the same mistake I did. I ordered the pool cleaner and then when it came several days later I took it out of the box and started using it. I already had a Hayward prior to this and assumed it worked the same. Been using it for a couple of months and it has worked fine. A few days ago it stopped moving so I took the bottom off to remove what I found was a small piece of gravel that was keeping it from working. While looking at a picture of it online to make sure I could remove the bottom I noticed there is a black ring that mine does not have. Then I remembered opening the box and it was sitting on top of a black ring that was not attached and that I assumed was some sort of packing piece to keep it from rolling around d in the box. That piece was tossed out with the box and I had to spend $20 to get a new one and watch a video on how to put it on. I feel like my husband now, who never reads instructions. I wish I had seen this prior to purchasing our first Hayward XL pool vac, which was more than double the price. It works well and my only issue would be needing a couple of extra pieces of hose because our semi-inground pool is large. It moves around the pool well and does a good job of picking up debris from the bottom. After using it I rinse it off and put it on the covered porch out of the sun. I didn’t take care of our first vacuum as well, but now I know better so hopefully this one will last longer.

Just what we needed. Was a replacement for Diver Dan. Delivery was very quick and Wanda is in the pool doing what she does best. Let me Revise this. Wanda seems to have a problem as her tail continues to Fall off. Contacted the company through Amazon however they said it would have to be referred to the manufacturer as it might be defective. So guess in the meantime while waiting for a response from someone, we will have to glue it Follow up. DO NOT BUY this product. The tail will not stay on Amazon just refers you to the seller seller Just refers you to the manufacturer. Piece of junk. Well I called the manufacturer, told to register the product which I did. Then they said to look at their web page for warranty and get a dealer which I did and called the closest one. I was told since they are in El Paso and I’m not they couldn’t help So much for warranty from Amazon, seller, manufacturer, and the warranty dealer

Easy to use, works well even it requires me to remove the stairs so it doesn't get hung up. The included adjustment valve and flow scale allowed us to dial in the suction to the middle of the band easily to guarantee that we don't suck up and ruin the liner. Only reason for 4 stars is that Wanda's tail likes to pop off to the point that we're using it without it. It's a small thing, and it's cosmetic, but if you include it, you should be able to use it without issues. Pool looks great.

She may not look like a serious pool tool but this vac is excellent for keeping the floor of my pool clean! It's so easy to set up and works pretty much on her own (with an occasion unclog when the pine needles get in the pool.) I had a pool party and the pool started turning cloudy the next day, then a little green forming on the floor. We connected her and let her do her thing and she got the job done. At this point, I leave her on a couple days each week to make sure that everything gets picked up and to keep algae under control during this hot summer! I think we have finally figured out how to keep the water clean. I have been struggling each year that I've owned this pool to keep it clean and stabilized. The pool is situated next to a tree line with pine trees and mimosa (lots of little tiny leaves that drop all the time) and she is the perfect addition to the pool tools.

My review would have originally been five stars, when I first bought wanda, she did a fantastic job, I was overjoyed how well she performed. I just cleaned her up and put it to work for this season, and was reminded that I was upset at the end of last season because she stopped working. Couldn't figure out what was wrong I'm watching number of videos too trying to figure it out. Today I watch some more videos and have come to the conclusion that there is some mechanism that causes her to be mobile, that has stopped moving. Whether it be bearings, or some deer assembly the fact that it only lasted one season is very upsetting.

Wanda is a miracle; I swear this thing can see and heads right for the dirt. Got it for my Intex 32x15ft pool. I have the sx2800 pump and sand filter and Wanda works just fine. If the skimmer is on, she goes a little slower but if I turn off the skimmer she powers through the pool. I checked flow and my setup was just a tic above the min line. Everything was plug and play with my pool right out of the box. I only vacuumed once this summer after adding salt to the pool. Wanda has carried the torch since then and she is a champ. Round of applause to Hayward and Wanda. The only complaint I have is her tail does not snap on fully, must be a little deformed. C'est la vie.

I love these automatic vacuums! We had a ladybug for several years then it stopped moving so I ordered this whale. I will run it in my pool for about 5 hours-you can even let it run over night. Definitely saves a lot of time from actually having to vacuum. I think it’s a bit overpriced for sure but it definitely works great!
