I just wanted to give my feedback regarding the battery life issue many people see with new/replacement Neatos.
I had an XV-11, it died on me a half week ago or so (wouldn't turn on, just made some odd numbers then shut back off). Talked with Neato, they shipped me a replacement. Received it yesterday. I fired it up, did 'new battery', let it charge during the day, then kicked off a run. It went back to charge after 28 minutes. 3 cycles, all around 20-30 minutes, never completed the bottom floor of my house. I let it charge, rinse and repeat, 3 times, 3 cycles, throughout the night. It never did more than 33 minutes on a run.
Fast forward to now. I pulled out my 3800mAh Amazon
battery pack, plugged it in, did new battery, and let the Neato charge. First run: 63 minutes (and 9 seconds) until the brush/vacuum shut off and it returned to base. It completed 3/5ths of my home in one pass. I've seen it said before, but my experience seems to indicate that the battery packs Neato are using, are now terrible. I don't know if it's dead cells or what (I'm not going to tear the pack apart to find out until after I talk with Neato about this) but I've seen a lot of forum posts with the same problems, who get replacement packs/robots from Neato without any resolution. If you're in the low run-time boat, and are willing to experiment, grab one of the 3800mAh packs from Amazon
. I think it was mislabeled as 3500mAh (still more than the stock supposed 3200mAh) and ran somewhere between 30 and 40 USD. I had gotten one for my old robot before it died, so had one laying around, and it completely correct my runtime problems.
The new-to-me Neato is Rev 113, running 3.1. My house is 75% relatively deep carpet, with the rest tile, and I am using the pet brush and filter. I also have a dog that sheds a dog every few hours, and due to not having a working Neato for near a week - I'm on bottom floor cleaning #4, and I still have to empty the dirt bin of hair every 15-20 minutes or so. Pretty much the worst case scenario, running the 3.1 firmware, and getting over 60 minutes of battery life. It wasn't even an overnight charge.
