This cordless robotic pool cleaner has been a fantastic addition to my pool maintenance routine. Setup was quick and easy—just charge it, place it in the pool, and let it do the work. It navigates efficiently and picks up dirt, leaves, sand, and other debris much better than I expected. I love not having to deal with cords, and the battery life is more than enough to clean my pool thoroughly. The filter basket is easy to remove and rinse out, making maintenance simple. It has significantly reduced the time I spend cleaning and helps keep the water looking crystal clear. If you’re looking for a convenient, effective, and user-friendly robotic pool cleaner, this one is definitely worth considering. Great performance and excellent value for the price! 🌟🏊♂️💧

I had been looking for something to make pool cleaning easier and this robot exceeded all my expectations. No cords, no hassle — just drop it in the water and it does all the work by itself. It cleans the floor and walls leaving the water completely crystal clear in record time. The battery lasts perfectly to cover the entire pool without interruptions. The 2026 upgrade is clearly improved: more powerful, quieter and smarter in its navigation. It’s easy to use, easy to clean and works flawlessly from day one. Hands down the best investment I’ve made for my home this year. Highly recommended for anyone who wants to forget about manual pool cleaning forever!

Wow! Yowza! Badoozoo!!! (Pros and cons at the end.) So, with some temporary limited mobility, my Florida pool was heinous. Despite being screened in, little dumb seeds work their way into my lanai and my doofy Corgi tracks in leaves. They stick to the tiles at the water line and are a pain to brush off every day. So my pool was uncleaned and untreated for a couple months. After 15 years of owning it, I'm just sick of it. Tech for robots wasn't the greatest several years back and I hated the look of vacuum hoses in my pool constantly but clearly, they've gotten much better, this bot proves that. So, I share with embarrassment my starting pool, because when I extoll the virtues of this little fella, you need to see where I started. I begin my story with pulling out the vacuum hose, holding the tube, and giving up and going to Amazon. I wanted a robot with an on-bot filter and a charging port. This has that. Now for what I did, absolutely ZERO vacuuming of my own. This bot did ALL OF IT!!! The filter holds about 5 cups of debris. -I ran it 3 times the first day (April 29th), stopping it myself (it comes with a perfect hook that matches the universal pool tool stick) about an hour in to empty and charge it back up. -Day 2, same. -Day 3 enough debris was gone I added 2.5 gallons chlorine for the algae blooms. It's pointless to shock it with so much debris so I just kept letting the little guy do his thing. -Day 4 and 5, it looked clean but I ran it anyway... and Day 4 still had a full debris tank! These weren't even visible to my eye. Furthermore, this actually sucks up paver sand that works it's way into the pool. That sounds unimportant, but that fine sand actually wrecks filters faster so this actually will help my main filter last so much longer! -May the 4th (be with you) I finally shocked it with 5 gallons of chlorine and some algaecide. My last photo is of today, the 5th. It took a week to get all the muck out, but all of 5 minutes effort of my own. I've ran the robot now approximately 25 times, it's been going morning, noon and night and still finds more to pull out. Pros - almost everything. It climbs the walls, cleans the tile line, brushes nearly all of it. It cleans in a grid pattern and generally does well going up and down walls. It keeps finding things I can't even see. It will save me a fortune, because it keeps chlorophyll filled stuff out of my pool I didn't know was there, which means less chemicals as well as saving a ton of effort on my filters. Cons - just two, one big, one small. The small - it doesn't brush the corners well and kind of trips up on it. So I did take 12.6 seconds to brush the corners myself, likewise with the stairs, mine are a bit odd shaped at an angle, it goes on the stair, but since the bot is stair width, it just pushes upward the whole time. After 10 minutes, it does give up on the stairs and moves on. The big - and it is important. The rubber tab on the charging port isn't perfect and a teeeeeny but of water does get into where the pins are to connect the power cord. The first time, I didn't notice and a tiny spark happened. So, I do have a can of air I spritz into it after taking it out and let it air dry for an hour before plugging it back in. All in all, I'm absolutely loving this robot. I can't even believe how much it's pulled out AFTER I thought it was spotless! ***** One thing I want to mention about the review that has a video of it "throwing stuff making it cloudy", that's extreme algae like I had. Nothing stops that but a real fabric filter and a major shock treatment. (Algae is about 6 microns. That's microscopic!) This guy gets out the debris that causes algae in the first place, it doesn't have a fabric filter. This fella pops it up with the brush, getting it off the ground and into that filter with the shock treatment. A pro cleaning service would also stir it up and make it cloudy.

I bought this cleaning robot to keep the pool clean effortlessly and it has been an excellent purchase. It vacuums dirt very well, climbs the walls and leaves the bottom impeccable. The battery lasts long enough to complete the cleaning and is very easy to remove and clean. It has saved me a lot of time and work. I totally recommend it for those looking for a practical and efficient solution.

I bought this vacuum because I urgently needed to clean my pool, and it ended up being one of the best purchases I’ve made. The first thing that impressed me was the battery life. I expected to stop halfway to recharge it, but it easily lasted through the entire cleaning with power left over. That alone saved me a lot of time. The suction is also stronger than I expected. My pool usually collects fine sand and plenty of leaves on the bottom, and it picked everything up without making me go over the same spot again and again. It feels solid, easy to handle, and it actually has the power to do the job. After using it several times, I can honestly say it was worth every penny. Cleaning my pool is now much faster and a lot less work. If you’re looking for a cordless pool vacuum with long battery life and strong suction, this one has been an excellent choice for me.

I purchased this a few months ago and have been using it regularly, almost daily for the past month. It works very well, is easy to use, empty, charge and reset. I drop it in early in the morning, it takes 90min-2hrs. I pull it out, empty the basket, charge it and repeat the next day. Two times it didn't park at the side of the pool but when I retrieved it, it wanted to "go" again so I'm thinking it got stuck on something and wasn't finished cleaning. You have three settings: floor only, side only and floor and side. I have an above ground pool and generally only use the floor only function. It picks up leaves, sand and debris but seems to have a more difficult time with flocculant (for example when you kill algae or drop the cloudiness from the water and it lands on the bottom). I think the reason is because as it moves along it stirs it up rather than collects it. This is where my old vacuum works better because I can control how slow I move the brush. Otherwise, it is working well and makes my pool more enjoyable. If your water is cloudy, it's harder to see it parked on the side. I figured out if I run it at night, I can see the lights on it and find it easier when it's done.

This robotic pool cleaner is a lifesaver! I have an inground pool, and it used to take me hours to clean it manually. This automatic vacuum does an amazing job, cleaning up to 2100 sq. ft. with ease. The wall climbing and waterline scrubbing features are fantastic – my pool has never looked so clean! The cordless design is super convenient, and the 180-minute runtime is more than enough to cover my entire pool. It’s so easy to use; just drop it in and let it do its thing. If you want to spend less time cleaning and more time enjoying your pool, this is the perfect investment!
