Nitro wall climber does not move sits at bottom of pool
Plug it in! :o)
Okay, assuming you have...do you get red or green lights on at the power supply? If so...that means:
1. you could have a connection problem between the power supply and the Nitro. You can check connectivity using a simple volt-ohm meter. Replacement cords can be purchased online.
2. One, or both of your drive motors are dead...usually, this because water enters the drive units. Replacing the motors is expensive...$140 or so for the front-wheel drive unit, and $185 for the big one in the center. But even then, these prices you have to search for...
Is it worth it? Hmmm, maybe...Robot cleaners are way too expensive...for what you get. So replacing motors every few years is better than paying $400 - $1000 every few years. These pool cleaners, like old cars, you can keep them going and going by replacing parts.
I am really happy with my Nitro...I put it in my 11,000 gallon pool about 3 times a month, and remove and clean the little guy out right after he is done. Then he goes in the storage rack out of the sun....and he is quite happy.
I used to leave him in the pool, for weeks at a time, and that was when I started running into problems with the motor units leaking...water has a LOT of pressure and is always trying to get in the motor units...and eventually it does. It;s been more than a year since I repaired the seal on my main motor, and replace the drive motor...and I expect a long life out of mine, which is now more than 3 years old and running strong.
