Hello. I just got an offer from a pool shop to replace the complete motor of my Maytronics Dolphin E30 . The problem I have is that the cleaner works fine but just for 15 min and then it starts to become slow and finally stops. Instead of changing the complete motor, may you suggest me...

Greetings, long time no post... I've got a 2.5yr old Maytronics E30. Just did a gear/wheel-bearing overhaul last month and all was working great. Now, the it turns off after about 25-seconds in the pool. 1. The controller stays on 2. I can take the E30 out of the pool, run it in test mode...

Hi all, I had to replace the swivel/power cable after 5 years the outside sheath was shedding bad. But now, after what I feel is a proper install, it keeps leaning to one side and tipping a lot. It never really did that before. I prefer not to buy a new one yet as they are not cheap and waiting...

Apologies if this has already been asked and answered. I searched and could not find. I have a Dolphin S300 pool robot. About 4 or 5 months ago I had a local pool supply company repair it under warranty. The 2 year warranty has since expired. They replaced the power supply/control unit and the...

My Dolphin s200 doesn't have any slots in the brushes for climbing rings, so I assume i can't just buy the rings and throw them on. Is it possible to replace brushes on an s200 to one that has slots for climbing rings?

My Dolphin M 400 motor isn't functioning. All motors work, however my control board 2410110LF rev 4 has a burned R38 cap and Burned U15 chip Anyone know where I can get another or have mine repaired?

Hopefully this helps someone. I recently bought a Dolphin pool cleaner and the power supply unit (PSU) died after a few months because it got wet. Now don't even get me started on the fact that a piece of equipment designed to clean a pool should be able to handle rain, but whatever... Not to...

My M5 is battery powered wireless. One side's drive will not go backwards. 1) in one direction it travels straight and both tracks spin. 2) in the opposite direction only one track spins. 3) the corresponding turn only works in one direction. 4) this happens whether you are in auto mode or...

I am so happy I switched to a Maytronics over 6–7 years ago. Love the things. My first may S200gave me 4 yr. 4/21 I purchased an active 20. And then months later, I purchased a new controller. Figured I’d get at least another four out of it. Fingers crossed we do. Anyhow, what’s currently...

Hey folks, I've been chasing a slipping drive gear issue with my s300i for awhile now. I replaced the drive gear twice and re-shimmed the belt wheel that is driven by the drive gear and eventually replaced the entire wheel and bushing Here's my thoughts: I think the failing drive gear is not...

Hi all, I just bought a new Dolphin Explorer E20. Not sure what that's equivalent to but it's a low end model with one brush. I've been looking at these things for 3+ years and finally pulled the plug: CA$1000 later and what a disappointment. I've run it around 5 times now and it just kind of...

Dolphin "Ultra Fine Filter" - can it pick up DE? Does anyone have one and know if the Ultra Fine Filter can pick up DE from the bottom of the pool? My old AquaBot cloth filter picked it up like a champ! But that robot has seen better days. The different filtering system on the Dolphin Active...

Does anyone know if there is a difference in warranty support when you buy a Dolphin directly from a pool store vs. Amazon? The model i am looking at is Dolphin Sigma (https://a.co/d/3NZ0cyy) from ‘The Dolphin Store’, hopefully they are the original manufacturers (Maytronics) and not some...

My Dolphin occasionally gets wrapped around a handrail and of course, the cleaning ends. I made barriers that I attach to the handrails but they are a bit hillbilly. What do you do to keep your robotic cleaner from getting caught by obstructions?

Just bought a new Active 20 from Marina Pool and Spa and decided to build my own caddy versus paying $150+ My analysis... 1) Don't need wheels and the $150 Dolphin's caddy's wheels are not that robust anyways 2) Don't want to leave power supply outside based on how many posts I've read...

Hi everyone, I have a Prowler 920, which uses the Maytronics drive motor 5521259-1. It is not working, and I've narrowed it down to the drive motor; it spins freely, gets stuck and becomes very hard to turn. I've seen a helpful video on how to get to the impeller bearings, but how on earth do...

I've spent way too much time researching robots. I finally decided on the Dolphin E30. I found a good deal for those interested. I searched Amazon and Google for the best prices, who doesn't, right? I came across one listed for $752.00. I added to my cart and left it there waiting to pull...

Hi there. I have an M600. About 2 years old. Bough from Marina after learning about it from TFP. The control panel doesn't work any longer, so I can't use bluetooth / wifi. Contacts Maytronics, they are sending a new one. It's been a month, and they said there would be a delay due to...

I'm wondering if anyone else has experience issues with a Dolphin Active 30i or similar pool cleaner. Issue 1: Sometime, more often than not, the cleaner does not run the full cycle. Sometimes it will run 30 minutes, sometimes an hour and then it just stops. The controller is still on like...

Hi TFP community! My Dolphin died the day after its 2 year warranty expired. Well, it was more like 2 months later, but still, I was expecting a longer life span than 26 months having paid $1600 CAD for it. Took it back to the store who’s technician confirmed the motor was fried. The store then...

So, I got a new E30 a few months ago, and starting to use it. Having some issues. It has ran a full cycle mabye once or twice I think. Normally, I start it and it runs backwards for a few seconds, turns on the vacuum pump, goes forward a second, then stops. Sometimes it resets itself and...

Hello All! I need some help. I've never owned a robot cleaner and I'm looking to buy one for my 16x32 in-ground rectangular pool with a vinyl liner. I've done some searching and it looks like the reviews are all over the place on which models are recommended. I like the idea of being able...

TFP community. After years of manually cleaning my pool, I've decided to invest in a robot to save time. I have a 20k gallon salt water pool that is 36x20. I pulled the trigger on a dolphin CC plus for $810 (linked below); however, after I ordered it, I did some more research, and am now...

Hi all. Considering an automatic vacuum and looking for robot recommendations. Pool is approx. 16K gal and rectangular in shape with a Baja deck. I recognize most robots won't hit the deck. The pool guy hardly stops by anymore, but that has been fine since installing the chlorinator. I am...

I have a 33k gallon gunite pool with a 10" concrete coping (see profile pic). There are also a few ledges in the pool. I'd like the best robot that can handle the walls (in addition to floors) and wondering if there are any that will handle the lip on my coping to get to the waterline. Anyone...

I'm in the market for a new booster pump; I'm seen mixed reviews for both the Pentair (LA-MS05) and Polaris (PB4SQ) Quiet is nice, but is the longevity as bad as it seems? (had my PB4-60 for 25 yr, just replaced seal a few times) I'll also consider the electric/robot IF the recommendation...

I have an Active 20 that I have left in the pool 24/7 for 2+ years. I am about to do a little tune up as the bottom rubber strips are looking a bit rough, but otherwise it's held up quite well. I have also noticed the power cable/cord is disintegrating a bit. I am seeing little blue chunks in...

Worked fine until it didn't. Stopped moving, took it in for repair, was told that it needs a new motor. Bought a new Dolphin and am putting this one up for sale -- you can either replace the motor or you can use it for parts. It's about 4-years old. It was well taken care of and I have no idea...

There's been a bit of a heat wave in southern Ontario and my pool got away from me. Noticed some green sediment on the bottom. About to start a slam, but the dolphin has been sitting in there for a couple days. I see lots of threads about whether it's helpful to run the robot, but that not my...

Hey guys, recently bought a Dolphin Nautilus CC Plus, and it worked fine for a month, but this past weekend, I noticed when it’s cleaning the waterline, it makes a very loud noise almost like something is grinding or rubbing on something. I do not remember if this was happening from the...
