    I purchased this lithium motor box assembly to replace my battery from last summer. I had purchased The Pool Blaster Catfish pool cleaner last summer, and honestly I was very disappointed in it! The suction was horrible, the battery took between 6 and 8 hours to charge, then would only run for 30 to 45 minutes! But, I couldn't really afford to replace it as I had just purchased it. So, this summer I took it out to use, and when I tried to charge it, it wouldn't work at all! Needless to say, I was pretty upset! I went online and found the replacement part.....but, I was very apprehensive about buying it. All I could think was, what if it's just as bad as the first one was? Well, I took a chance, and WOW!!! This new battery set up is totally different from the original one. My Catfish cleaner is working absolutely wonderfully now! It is picking up everything! It charges much faster, usually in 3 or less hours! I can clean my pool out several times before recharging too! I would now recommend this product to anyone! Actually, I have let my neighbor use it, and she is getting one now too! This new lithium motor box assembly made the most impressive difference!

  5. new Catfish motor assembly

    I have only used this new motor once. It seems to work as well as the original one. It is great for picking up dirt and small debris from the bottom of the pool that other products miss.( Make sure you have the extra fine filter along with the standard one.) I like the push button start and stop on the top of the assembly, it is much easier to use than the older method. Changing out the old motor for the new was very easy. I would recommend this vacuum to anyone with a pool. I have a 15 by 30 ft oval above ground pool and one charge will generally clean it. I only hope that this motor assembly lasts longer than the two seasons my last one did.

  7. Didnt think we needed it but glad we bought it

    We lost our charger cord in a move over a year and a half ago. I decided to just log in and buy a new cord, when we seen the motor was a great price we decided to get it as a back up. I'm glad we did. Once we got the cord our old motor would not hold a charge. Very easy to install the new one and works great.
