5.0 out of 5 stars *** UPDATE #2 *** It's working GREAT!
Reviewed in the United States on July 22, 2023
I had my doubts, but I read reviews and went ahead and bought it. I charged it fully and turned it on and dropped it in my above ground pool. I did take the ladder out first because a lot of the debris collects around the base of it. At first, it was making very short passes, it was sucking stuff up nicely, but not going very far before moving in the other direction. Soon, however, it began to make longer passes. It stopped, at one point and I lifted it out, using the included hook, opened it up and I was shocked to see how much of the ultra-fine junk it had picked up. Thr filter is SO fine that it picks up the tiniest particles of dirt. I rinsed it all out, put it back together and back into the pool, where it moved around, just like a Roomba, until my pool was beautifully cleaned up. I'll be using it every 3-4 days. I'm very pleased with the results. No brushes to possibly damage the liner and its so easy. I highly recommend this for any above ground pool
*UPDATE*
I'm so impressed by this little machine. I'm posting pictures that I took today after the hurricane a couple of days ago, I'm in Florida. There was just a lot of small tree trash in the bottom of the pool. This little thing is priceless. It picked up SO MUCH small debris. I've added a picture of just some of what it picked up. The other pictures are of it taken apart, which is so easy, and it's all back together. I highly recommend this for above ground pools. Turn it on and drop it in. Bam
UPDATE #2- I'm more and more impressed every time I use this little champ. We recently had the WORST dropping of Oak Tree pollen and the bottom of my pool was covered with tiny little brown dots of that pollen. It was so small that my skimmer net couldn't get it out. But this little baby got all of it. I had to clean it out several times, which is so easy (as I stated previously) but, the bottom is now clean. I really can't say enough good things about this machine. Whenever it gives out, I won't hesitate to buy another one.

1.0 out of 5 stars Stopped working second use
Reviewed in the United States on August 27, 2024
First time I used it it was picking up a lot of debris. Didn’t get stuck anywhere like others were saying. One issue was when I was picking it up out of the water small debris was floating out of it. I emptied it out put it back in the pool, it did its job. Once again, removing it small debris was coming out and going back into the pool. Charged it . A few days later I was ready to use it again. It started cleaning my pool and then shortly after about 10 minutes or maybe alittle more it got stuck, but there was nothing to get stuck on. I removed it debris was coming all out. Turned it back on, put it back in my pool. It started to move a tiny bit and froze again. Removed it again put it back in the water and this time it just sat there and didn’t move at all. I’m not going to bother to go through technical support. You pay money for something you shouldn’t have to go through that so I am just returning it .

Suction is important. The suction meter provided is useful and it cleans the pool well. Instructions and assembly were easy. The pool vacuum stays in the pool almost 24/7. Unless it's an occasional party, I can make it easier for guests to swim. It is small, but powerful. The pool looks great! I put it in the shallow end and it kicked right in and started working. Looks fun and is built to last, best seen.

3.0 out of 5 stars Deceptively Effective—Not the Cleanest Experience
Reviewed in the United States on October 15, 2024
I’d give the Grennix Cordless Pool Vacuum 3 stars. It does an okay job—managed to pick up the heavy dirt in my pool, which is great. However, the vacuum has a tendency to scatter smaller debris around, leaving the pool looking deceptively clean from a distance but not so much up close. It's frustrating because while it handles the big stuff, the finer dirt ends up floating around instead of getting sucked up. It’s not a terrible product, but it could use some improvements for a truly thorough clean.

We’d had a couple monsoon storms roll in and I couldn’t keep up with cleaning our small above ground pool (~10x7’). We have a small stick vacuum that performs well but is really just for spot cleaning. After the storms, I would still be left with a significant amount of fine particle dirt resettling at the bottom of the pool.

Enter, this little robot vacuum! I was skeptical at first and here is why. We had a fairly thick layer of that fine dirt on the pool floor and when I placed this vacuum in, its water jets blew everything around. So it appeared that the dirt was being blown away before ever even getting to the intake. I let it do its thing until the battery ran out. I took it out to dry. I waited a couple hours, looked in the pool… it was 90/95% cleaned up! The difference was stunning. Hardly any dirt was left to resettle at the bottom and when I ran it a second time it was perfect. Swimmable even for the most picky with water quality.

Now we run it once every day or two for reagular maintenance and occasionally still use the stick vacuum to compliment it and get any small bits it may have missed. Overall this little machine has reduced the workload and frustration of maintaining our pool to basically as close to zero as you can get. Awesome and can’t beat the price!

I have tired numerous hand held pool vacuums and they don’t even come Close to what this can do! An hour with a hand held vac and my arms and back were killing me! It’s light weight, takes about 2hours to charge and boy does it go and leaves a clean path behind it! Amazing and fun to watch! Runs over and hour and better yet it’s so easy to clean, has a large filter that you can pop right out, rinse taking no time at all. It’s my first robot vacuum and I highly recommend it for the price!! My pools never been cleaner!!
