If your Dolphin Advantage Pool Cleaner is not operating in a desired fashion (i.e. not climbing walls, or not able to gain traction on pool floor) then you may have to replace the tracks on your unit. The following is how you do so:

Step by Step


Step 1

Place your Dolphin Advantage Pool Cleaner upside down so you are able to reach the Bottom Lid Assembly (BLA). Delete sentence [At this point you should be seeing your Dolphin pool cleaner from that vantage point,] On either side of the unit you will see a yellow clip holding the bottom into place. Release these clips and carefully lift the BLA of the unit, and place it to the side.

Step 2

At this point you should be able to see clearly down into the belly of the Dolphin Advantage Pool Cleaner, where the motor is housed. On each side of the cleaner housing there are 3 screws, (6 screws total) that will need to be removed to gain access to the side panel. For easier access you may want to remove the motor's protective

Step 3

In cases in which removing the motor unit is necessary, first remove the screws on the tabs of the screen that attach the screen to the housing.

Step 4

Slide the screen up and the mounting slots and place screen to the side. To remove the Dolphin motor you will need to remove the Dolphin motor mount screws that are mounted on the outside of the unit sidled next to the handle assembly, that step is picture to the right.

Step 5

After removing all the screws from the inside, you can then unseat the aqua green side panel. This may be a little tricky to get a hold of, so you might use a flat-head screwdriver to gently pop the panel off its moorings.

Step 6

After removing all the screws from the inside you can then unseat the side panel, this may be a little tricky to get a hold of, so using a flat-head screwdriver to gently pop the panel off its moorings.

Step 7

Side panel removed - This is what you should be seeing from your point of view before we move forward.

Step 8

Before removing the track from the Dolphin Pool Cleaner you will first need to slide off the two Guide Wheels that maintain the track's position on the roller. After removing the guides, take a chance to inspect the wheels and to be sure they spin freely and are not cracked or damaged in any way. Replacement Guide Wheel, part#: 3295-454

Step 9

Next you will remove the Pulley Bearing, this is the guide that is connected to the motor shaft, after removing once again inspect the roller to be sure there is no undue wear and tear. Replacement Dolphin Advantage Cleaner Pulley part#: 3295-199

Step 10

With the guides and pulley removed, the track should be free and clear to be taken off the brush rollers. Simply slip the track off the grooved edges of the rollers.

Step 11

After old track is removed from the Dolphin, re-install the pulley. Once that is in place you may begin to retread the rollers with the new track. Snake the tread around the roller then around the pulley. Replacement Dolphin Advatange Track part #: 3295-299

Step 12

Once the track is secure around the pulley, you may insert the guide wheels on their mounts. Be sure that the notched ends are faced down and locked on the grooves to the side of the unit.

Step 13

Once the new track is in place and the pulley and guide wheels have been reinstalled, you may screw the side cover back into position. If you removed the motor to access tthe pool cleaner's inner screws, it would be best to save that until you have securely fastened the side panels to avoid any issues with space while trying to maneuver tools inside the unit.

Step 14

When placing the motor back in the unit be sure that it is sitting in the mount brackets snugly before screwing item into place, brackets are pictured to the left. When mounting the motor onto the brackets, align and insert the motor shaft into the slotted pulley drive.

Step 15

With motor secure, slide the filter screen back onto its guides and secure to housing. Check to make sure there are no loose or out of place screw before going any further.

Step 16

After you complete track installation you can insert bottom lid assembly, fasten the yellow clips and continue use of your cleaner.

Dolphin track - The Part # of the Dolphin Advantage Track is 3295-299 and it is 12" in diameter and 1" thick. It has large teeth on the outside and small teeth on the inside. If this description does not match the track you ordered, or you have any other questions, please call one of our service reps at 877-372-6038. We will be glad to help you.

the part that is shown in the directions is not the same part that is pictured. My unit takes the part that is in the instructions and the part I received is too wide and the teeth are not the width of the track, but merely little teeth that do not match the grooves of my machine. I thought I ordered the correct part because it looks exactly like my unit, but I don'tthink this is going to work.

cleaner tracks - These tracks are tight and generally it helps to have two people to replace them. See our related guide on "How To Replace Maytronics Dolphin Nautilus Tracks". It has additional instructions on replacing these tracks.

I just got my replacement tracks in today. I'm hoping they're the right tracks. They seem tight and I'm having a hard time getting them to fit around both of the big bottom rollers at once. The track looks like the one in the picture above, but not the one pictured in the instructions. Is there a trick to maybe stretching it out a bit?

I replaced the tracks and brushes yesterday and it took me an hour tops. The instructions were simple to follow and my Dolphin Advantage pool cleaner is running like a champ. Thank you INYO Pools for having the replacement parts, the speedy delivery and simple do it yourself instructions. Looking forward to doing business with you in the future.

when I helped my mother with her pool upkeep I noticed how loose the treads were on her pool vacuum. I got brave and decided to order replacement parts. The new belts arrived in the mail WITHOUT directions. Oh, my. After a moment's panic I found this detailed instruction - with pictures THANK YOU very much!- and I actually replaced them myself. I do so appreciate the time you took to share this knowledge. Vacuum is working like new. Everyone is pleased, and I'm proud.

Great instructions, these type of instructions help us do the job ourselves and I thank you for it. I would like to add my experience for others.
1- The bottom screws inside the unit are difficult to take out if you have big hands, there isn't a lot of room to work with especially on one side.
2- The side panel was tight and difficult to pull out, you need to force it without breaking it.
3- Replacing the track was easy but I believe the teeth are not the same either side so make sure you have the track correct. I would replace both tracks
4- The track is tight at first you need to force it in
5- The side panel will not go in easy, it does not align with the middle spindle. I used a screw driver to gently push down on the spindle while pushing in the side panel.
6- When screwing the panel back on, make sure the piece where the handle screws on pushes down easily, sometime they get stuck and you need to unscrew the panel.

Once you commit in doing the job, you have to finish it, there are not that many repair service centers around. The best bet is to learn as much as you can on how to do it, and then proceed. It looks a lot more difficult than it is, and at some point you will question yourself why you are doing it but at the end you will feel a sense of accomplishment. Good luck.

jalatianos - About all I can suggest is to look where the power cord goes into the cleaner and see if you bumped a connection when you changed the track. Also check the fuse in the power unit and make sure the cord at the power unit is on tight.

I just replaced one of the tracks for my Dolphin pool cleaner and it appeared that everything went smooth. Problem is that the unit does not turn on now. Any ideas as to what I should look for?
Thanks - - John
