I see this thread is not quite two years old. We purchased our first Pool Blaster Max some years ago, used it twice and got hooked on the simplicity. But the light on the charger never changed from red to green. So I just unplugged it after four hours, used it the next time (each cleaning took about 30 minutes) and the battery ran down just before I finished. Tried to charge it again that evening and again, the light never changed. It also never worked again! I was never able to get it to charge again and it costs more the send it in for repair than to just buy a new one (almost). So we returned to our Aquabot Turbo until it got too heavy for me to deal with anymore. The next summer, we bought ANOTHER PBM and had the same problem. We took it to Interstate Batteries and had them see if they could charge it. They removed the battery pack and gave it a full charge. It lasted for two 30-minute cleanings and again, same problem - I was not able to charge it. We had them build a custom battery pack, they returned it fully charged and again, two 30-minute cleanings. Returned it to Interstate, who, again, removed the custom-made battery pack and fully charged it again. By now, we have gone through a few summers since the first Pool Blaster Max. I ordered another wall charger, and again, the red light never changed to green - so I did what I always do, set a timer and babysit it. (And yes, Interstate tested the wall charger before they did anything with the cleaner and it showed to be fine) So we gave up on it and kept using the Aquabot, though hubby would have to remove it from the pool for me. I'm very tired of the rigorous routine with the Aquabot, though I absolutely love the little guy's excellent quality and performance. I just can't handle the weight of it. Summer is approaching again in Texas and we hope to avoid anymore grapefruit-sized hail, like last summer (4-11-2016), got a near completely new pool out of the hail storm and WOULD REALLY, REALLY LIKE TO HAVE AN EASY SUMMER, with an easy method for pool cleaning.
All you guys who have purchased the Max, now that it's been nearly two years, have you had any charging problems? It's been about four years or so since our last Max purchase and I am leery of adding another useless cleaner to our collection this year!
