Bests & Worsts Reviews from Amazon

I won't say I hate it. But I hate that it is so hard for me to love it. I am a working mom. This is a nice product to keep my floor clean enough on a daily basis, so I only need to manually steam mop once a week. I had 4 braava during the last 3 years. The first one (#1) worked for 8 months, then 1 day it started to get disoriented and just spin on itself. Customer service told me there was problem with the computer system. Because it was still within 1 year warranty. I got a replacement. The replacement (#2) worked for about 6 months, then suddenly stopped charging. The customer service guided me to buy a new battery ($30+). The battery is supposed to work for at least 2 years according to the product description. It was disappointing to me to have such a short-life one. Anyway I got a new battery, #2 worked for another 10 months, then stopped charging again. New battery does not work this time. Customer service diagnosed that there is electrical problem with the robot, there is no easy fix, the only solution is to get a new one. And because it is out of warranty, I have to pay $180 for a new basic one without any of the accessories. Though for sure disappointed, I still paid for robot #3. Just so I do not need to mop the floor everyday by myself. After my complaint, the customer service was nice enough to give me 15% discount. Still $150 out of pocket. #3 worked for 2 months. This time, the pad wrapping one of the wheel is peeling off and jamming the wheel when it is running. Replacement #4 is on the way to me. I can't believe how this product can be SOOOOO UNRELIABLE, or how come I am so "LUCKY" to experience all these uncommon problems. I have an irobot vacuum for 4 years, never give me any problem. I was told there is no extended warranty available for this product. Does it mean the manufacturer only confident for it to work properly for 1 year? It will ridiculous to buy a new one every year. For God sake, it is not something cheap. Customer service was always very nice. But that does not solve my problem. I am very very disappointed. And very annoyed. Yet I still need it. If there is a competitor product becoming available. I will certainly try it out. Irobot should be shamed for letting down such a royal customer like me.
