(Upgraded 2026) Nautilus Titan Wi-Fi Automatic Robotic Pool Vacuum Cleaner Waterline Scrubbing, Multi-Layer Filtration, Ideal for Inground Pool up to 50 FT in Length

Bot does a great job of cleaning the pool. Very happy with function/performance. It did have an error and stop working after 6 months. The 3yr warranty is great, and Maytronics is happy to repair it. But - you will need to pay for shipping to them, so factor that cost into your calculations. After forum searches when trying to troubleshoot - I determined that these often have issues like mine. I originally thought it might be corrosion of the twist cable (as that is common.) However, mine only had minor non-impacting corrosion. In any case, be sure to save the box for when you need to get it fixed!

Yet another update: The second power supply has now failed. The first symptoms of the failure were that it had apparently "lost" its configuration and had to be re-adopted/re-connected to my WiFi network, the same as if it were a brand new unit. It lasted for 1 cleaning. The next time I tried to use it, it was in the same state only that time, despite attempting to re-connect it a half dozen or more times, it would not successfully connect to my Wifi network. Mind you, the power supply itself when in use sits less that 30 feet away, line of sight, from an outdoor Ubiquiti Unifi Pro access point that's also supporting multiple WiFi cameras that are several hundred feet away and are all working fine, so it's not a WiFi signal problem. Maytronics continues to pretend that they're not aware of chronic wide-spread problems with these power supplies. Revising this review again. I now truly regret this purchase and wish I have never seen this thing. Here's the latest: It's about a year old at this point, still in warranty. So far we've had one power supply go bad. It took a long time to get a replacement because they were out of stock. I assume because so many of them fail. I just dropped off the whole system at UPS to ship for more warranty work. Now we get nothing but error messages saying that the controller can't communicate with the robot. After talking with support they decided I needed to send the whole thing in (at my considerable expense) to the repair center in Georgia, still under warranty. Here's the telling part: As soon as I walked into the UPS store with that huge box, the counter person said, "That's a pool robot, isn't it?". Says I, "Yes, how did you know?" Counter person, "Because we get a LOT of those." All Maytronics? "Yep". Don't get me wrong, when it works it works really well, but with two big problems still under warranty and the initial cost, I tell you that dumb, simple pressure side Polaris we got with the pool is looking hard to beat. Further update: Checking the UPS tracking told me it arrived at their facility 7 days ago, yet I've heard nothing so I contacted them for a status. Here is what I was told: "• I see that your unit was delivered on 9/25/24. The unit has not been received in the system yet. Receiving is one week behind due to a surge of units coming in needing repairs. The turnaround time is 2-3 weeks after being received in the system. We appreciate your patience during this time. Once repairs are completed the unit is shipped back to you and a tracking email is sent. They also send an email letting you know when the unit is received in the system." So their receiving is at least a week behind, and service is at least 2-3 weeks behind. Why? Because of the number of units that have had problems severe enough to require them to be sent in for service. To quote a friend of mine: " It's h*ll when it's well, but it's sick ALL the time!" Original revision: After having lived with it for about a year now, I'm revising my review. Performance-wise, it works very well and I'm happy with the job it does. HOWEVER: Slightly less than 12 months in, the power supply has completely failed and will not power up at all. Contacting customer support, they agreed to ship me a new power supply with almost no questions asked. In fact it was SO easy that now I'm thinking that Maytronics must already be aware that their power supplies are plagued with frequent failures, especially considering some verbiage I found on their web site about the process for dealing with power supply problems. Also, although the robot itself can be operated without an internet connection or with their app on a smart phone, most of the features are not available without one or both of these. For instance, you can't set up a cleaning schedule, you can't alter the type or the duration of the cleaning cycle, you can't manually "drive" the robot around, and you can't get feedback about the condition of the filters. Their default mode of operation requires an active internet and wifi connection as well as a connection to the Maytronics servers. It's possible to switch the robot to communicate with the phone app over bluetooth, but that option is somewhat hidden in the menus and even in that mode, it's not clear whether or not the system still communicates back to Maytronics. (I could find that out via a Wireshark trace but so far, I haven't cared enough to do that.) I'm still happy with how well it cleans, but the "other stuff" above is now more of a concern to me personally. Original review: We have a large-ish 40,000+ gallon pool Likes: Does a thorough job. Filters relatively easy to clean. Being attached to a cable as opposed to wireless may seem like a con, but it means the suction motors can be stronger and more powerful than they could be if it were 100% wireless which means it does a good job. Climbs/cleans walls and cleans the waterline very well. Dislikes: The Android app used to control it does not have an 'exit' function. You can dismiss the app by using the 'home' button on your phone but the app will continue to run in the background which means it's still consuming memory and battery (and possibly sending who knows what information back to the Maytronics servers). To completely exit the app and stop it, one has to use the phones "force stop" function. (This is probably true of all Dolphin robot cleaners). When I reported this behavior to tech support, they seemed unconcerned and not willing to fix it so now that I know, I always just force stop the app when I'm done.

I am very happy with this product! I have gone through several other pool cleaning robots (Dolphin Cayman, Premier, and others) to finally get a pool cleaning robot that actually works. It isn't perfect, but I have a very old in-ground concrete pool with funky curves and stairs that was recently resurfaced. My biggest complaint was that other robots always got consistently stuck on the concave deep-end drain. So far, the Titan has been able to navigate the drain pretty consistently. The images show the pool with the Titan underwater. I really enjoy the large basket, but living in the desert where it gets very windy and dusty, the basket accumulates a lot of mud, so it needs cleaning about every three days. Theh Titan can be scheduled via the My Dolphin App, so it runs daily each morning. I I set it to floor mode, and brush the walls and steps manually. This seems to work the best. Out of the box setup was easy, as was the app. As the title says, the Titan is about an 80 percent solution to my pool cleaning (which I consider a win)!. I have not had to run a vacuum since purchasing the unit. The pool had several days of El Paso dust waiting for the Titan to arrive, and after three back to back cleaning cycles, what you see in the images (plus some brushing) was the result from the Titan. Neither the Cayman nor the Premier could handle even a daily cleaning without getting stuck on the drain. I am very pleased with the unit, and my only regret is that I did not spend the money to buy the Titan first ( I am now the proud owner of three pool robots with two parked permanently in the shed). Save yourself the hassle and spend the money on the best unit; you will wind up spending it anyway to get the results you expect.

So this is the more advanced the newest sexiest technology. I found a very helpful because I had an old dolphin before it gets stuck on the platform all the time this one I’ve been using it for almost a month and it doesn’t seem to have that problem, which took a big load of my shoulder Also is sent you give you indicator about the cartridge if the cartridge is full you’ll tell you in your alert and then so we can go clean it up overall I’m satisfied it just that count to pick me up that function doesn’t work for me I’m gonna load another video to explain that to you guys overall I think it’s $2000 save me a lot of time and trouble I think it’s worth it ?

I really wanted to love this robot considering the ($1500) price and the reputation of the brand, but my experience has been incredibly frustrating. The cleaner worked fine initially, but after a relatively short period of time it started having communication and startup issues. The power supply would still connect to WiFi and Bluetooth, but the robot itself would not move or respond properly. Troubleshooting this thing has been a nightmare. Between the app pairing issues, proprietary cables, confusing error messages, and expensive replacement parts, it feels like you’re buying into an ecosystem designed to fail expensively. Even diagnosing the problem is difficult because the robot, cable, and power supply all seem dependent on each other to function correctly. For a premium-priced pool robot, I expected something much more reliable and serviceable. Instead, I ended up spending hours troubleshooting connectors, cables, and pairing procedures instead of actually cleaning my pool. Replacement cables alone cost over $200, and the repair costs quickly approach the price of a new robot. The app and “smart” features sound great on paper, but in practice they just add more failure points. Overall, I’m very disappointed with the durability, repairability, and ownership experience. I would not purchase this robot again and would not recommend it to others.

So I got this cleaner for our fiberglass inground- had it for about a month, used it about 10 times now. It does a great job cleaning the floor: gravel, leaves, fine dust… Very long cable. Never got tangled as in other review. Easy to empty the basket(it has a handy trap door at the bottom-clever!). The issues I find with it: 1. The app is working, but the manual control is soooo delayed- it’s frustrating to try and clean a certain area or even try to guide it to a certain spot to pull out of the water… it could be due to the WiFi connection limitations, but Bluetooth is not an option for me- I like to control if from anywhere. 2. It doesn’t seem to have an option to empty the trash bin without resetting the cleaning cycle- you get a notification that it’s full, but as soon as you take it out of the water is basically turns off(I get it: safety and stuff), but there should be a way to “pause to empty bin” option or something… It messes with your schedule if you plan on taking the unit out after the cleaning cycle is complete. 3. The waterline cleaning is hit or miss- it’s weirdly inconsistent. Sometimes it won’t be able to climb the wall to be picked up out of the water, other times it’s just fine… Overall- I would probably buy it again- the reliability issues? I got the extended warranty thru Amazon for $150 for extra 2 or 3 years, so that’s 5 years of worry free use. It’s definitely a premium unit, it feels nice, it does a good job cleaning the pool, didn’t have any issues with it loosing connectivity etc… it never got stuck or “confused”, it does what I expected, but $2000 seems pretty high.

The first one we purchased lasted nearly 5 years, it’s a little expensive for a toy, we had it in for service twice. It’s expensive to ship it to them, you’re without it for weeks, no communication at all, and then it just comes back. When it came back, it died within months. We purchased a second one - sounds dumb, doesn’t it? But it was cheaper than getting a new Vacuum system. The second one didn’t make it a year. Faulty cord, faulty motor, faulty electrical connection, faulty computer system. We’ve been without it for a few months, having to manually clean our pool. Customer service is again very poor, zero communication at all. Difficult to reach a human, no information shared at all. Our local dealer provided repairs and then dolphin refused to let them continue repairing it and demanded that I spend $80 to ship the unit to them. They’ve had it for two weeks with zero communication. I’ve been hounding them with phone calls and emails and I get a notice tonight that FedEx is supposed to deliver it to me tomorrow. I have no idea if it works or if it doesn’t work. I don’t know what they replaced. I don’t know anything. Other than, I need to be home tomorrow to receive it. Save your money, don’t bother buying these products. My second one, and I’m a fool for doing it twice.

For the money a complete waste. This is my second Maytronics, first stopped working after two seasons but hoped it was a fluke, and very disappointed. Will absolutely not clean the water line, spends most of it's time doing wheelies (from day 1 and I've watched the corrective videos completed all steps, and practically turning itself upside down. Debris simply scatters and follow the unit. No clogs, no tangles. Will be returning ASAP - much better and cheaper models available. Not worth the money, for $1500 I shouldn't have to immediately start troubleshooting and watching YouTube videos day 1. The two hours limit is pretty ridiculous as well. The app rarely connects and the green WiFi light flashes regularly despite being 15 feet from the router - my phone has full wireless signal and 600Mb up and down from the same location. Save yourself the frustration.

Last summer was the first year I had the pool robot it worked great. This summer 2024 our second summer with the robot and still works great. It works so well I am questioning the need for the pool company I hire every summer. My pool is 20’x40’ and it does a great job cleaning it. The picture are for today July 2nd, we had fireworks at the house which left a massive mess in the pool. I turned on the Dolphin to start cleaning after the fireworks, then the normal 5 am clean this morning. I was so surprised as to how clean it was when I woke up. Still some debris in the pool but I think that is all due to the wind blowing it in to the pool from the grass during the day. I am also on the second season with my Betta (surface skimmer) these two in conjunction keep my pool super clean. I must say I find the Dolphin filter to be way better than my sand filter! I am a big fan of pool robots!!!

Easy to use, frequent cleaning of the floor, walls keeps the algae under control with lower levels of Bromine
