What’s the best robotic cleaner you’ve used?

Mine just died and I need a reliable recommendation.
I’ve been using the Dolphin Nautilus CC Plus for the last two seasons and it’s been rock solid. It cleans the floor and walls pretty well, and it’s simple to clean the filters. Not the cheapest, but honestly worth it for the time it saves. I just let it run a few times a week and barely have to vacuum manually anymore.

I usually recommend the Polaris 9550 Sport. It’s a bit pricey but super powerful, especially for larger pools. It handles fine debris and bigger leaves really well. Plus, it comes with a remote and programmable timer which a lot of people love. Dolphin is a solid choice too if you want something plug-and-play.

I’m still new to robotic cleaners, but I’ve been using the Dolphin E10 for my small pool and it works great for basic floor cleaning. It doesn’t climb walls like the bigger models but it keeps the bottom clean and was more affordable. If your budget’s tight, it’s a good entry-level option.

Ugh, mine just gave out last week—total pain. I’m really hoping to find one that’ll last more than a couple of seasons. Anyone have one they’ve actually been happy with long-term?
 
I use the Dolphin Nautilus CC Plus and it’s been great. Cleans the floor and walls, and it’s easy to clean out. Had it for two seasons with no issues. Definitely worth checking out!

I’ve had great luck with the Polaris 9550. It’s been super reliable and does a great job with both the floor and walls. A bit pricey, but worth it if you want to just drop it in and forget about it.
 
Great recommendations so far! I’ve actually been eyeing the Dolphin M500. It’s a bit on the expensive side, but I’ve heard it does a fantastic job on larger pools and even handles the finer debris. Has anyone used it for a pool with a lot of corners or steps? Would love to hear if it works well for that!
 
I’ve been running the Maytronics Dolphin Premier for about two years now, and it’s been surprisingly dependable. What I like most is the interchangeable filter options; you can swap between fine and ultra-fine cartridges depending on the season, which helps a lot when leaves are dropping.

It also handles steps decently, though not perfectly. The price tag initially made me hesitate, but the low maintenance and consistent performance have made it worthwhile.
 
I’ve been using the Dolphin Explorer E30 for a while and it’s held up well. What sold me on it was how light it is compared to some of the bulkier models, so pulling it in and out isn’t a hassle. It does a solid job on both the floor and the lower part of the walls, and the filter basket is easy to rinse out. It’s not the cheapest option, but for the convenience and the fact that I don’t have to babysit it, I’ve been really happy with it.
 
If you’re looking for reliability and minimal hassle, I’ve been really happy with the Dolphin Nautilus CC Plus. I’ve had mine for three seasons now and it’s still going strong. It handles both the floor and walls well, and the filter basket is super easy to clean. The only downside is it’s not the cheapest, but for the time it saves, it’s totally worth it.

For larger pools or ones with a lot of corners and steps, the Polaris 9550 Sport is also excellent. It’s a bit pricier and bulkier, but it’s very powerful and programmable, so you can basically set it and forget it. Between the two, I’d pick based on your pool size and how much automation you want, the Dolphin is lighter and more plug-and-play, the Polaris is for heavy-duty cleaning.
 
I picked up an Aiper Seagull Pro earlier this year after my old cleaner quit, and I’ve been pretty happy with it so far. The best part for me is that it’s cordless, no cables floating around or getting wrapped around the ladder. It’s not perfect on steep walls, but it handles most of the pool floor without missing much.

The battery lasts long enough for a full clean on my mid-sized pool, and it’s easy to empty out afterward. I wouldn’t call it fancy, but it’s been consistent, which is more than I can say for some of the pricier models I’ve owned before.

If you just want something that keeps the floor tidy without needing to babysit it, it’s worth a look. For pools with lots of steps or awkward corners, you might still want to go for one of the bigger Dolphins, but for basic cleaning, this one’s done a solid job.
 
If you want reliability without babysitting, the Dolphin Nautilus CC Plus keeps coming up as a favorite, floor and walls, easy-to-clean filter, and mine’s lasted three seasons with no hiccups.

For larger pools, lots of corners, or steps, the Polaris 9550 Sport is a beast, programmable, powerful, and handles bigger debris well, but it’s heavier and pricier.

For a cordless, simpler option, the Aiper Seagull Pro is surprisingly consistent for just the floor, and no cables to tangle. It’s a solid pick if you don’t need full, wall coverage.

Basically: small to medium pools → Dolphin; bigger or complex pools → Polaris; simple cordless → Aiper.
 
I’ve gone through a couple robots over the years and yeah, the Dolphin love is real. Mine’s been solid on the floor and walls, no drama, and it definitely saves my back. But I’ll be honest, the robot wasn’t the thing that finally made the pool look consistently clean. It picked stuff up, sure, but after busy weekends the water would still look dull even when the cleaner ran its full cycle.

That’s when I realized the robot was just moving fine junk around, not actually solving it. Higher bather load, sunscreen, yard dust, all that stuff stayed suspended. Filter pressure would creep up 4 to 5 psi and the water still wouldn’t pop. I started using aquadoc flocculant every now and then, especially after parties. Shut the pump off overnight, came back to a layer of gunk on the floor, vacuumed to waste, and suddenly the robot actually had an easy job again.

So yeah, a good robotic cleaner matters, but it works way better when the water chemistry is dialed and you’re not asking it to fight suspended mess all the time. Robot for daily pickup, floc when things get out of hand. That combo finally made mine feel worth the money. Curious if anyone else noticed their cleaner “works better” once the water’s truly clear?
 
Mine dying is always what sends me down the rabbit hole too. I’ve run a couple over the years, corded and cordless, and the one that’s stuck around the longest for me is a Dolphin Nautilus CC Plus. Not exciting, but boring reliable, which is kind of what you want. Floor and walls get done, filters rinse out easy, and it doesn’t need constant babysitting. I run it a few times a week and it keeps the day-to-day debris under control.

That said, I learned the hard way that even the best robot has limits. After heavy bather load or windy days, mine would run its full cycle and the pool still looked a bit flat. Filter pressure would creep up 4 psi, chlorine was fine, pH steady, but the water just had that dull look. Turned out the robot was chasing suspended junk it cant really grab.

What helped was treating the water first, not upgrading the robot. I’ll use aquadoc flocculant once in a while when things get messy, shut the pump down overnight, then vacuum to waste in the morning. Once the fine gunk is gone, the robot suddenly looks like a hero again instead of a slacker. So yeah, Dolphin is my pick for reliability, but it really shines when the chemistry and filtration arent fighting it the whole time. Anyone else notice robots work way better once the water’s actually clear, not just circulating?
