The typical LiPo charge cycle is 300-500 before the battery drops below 80%. You are looking at 3-5 years before this happens and you will have lost about 25 min of run time from 120. Considering that it features auto return, the battery is hard to abuse. I don't think it's not the most important question
@@notenoughtech I say it's the most important question because I own a similar robot vacuum and have had to replace the battery after about three years of intermittent (not daily) use. The replacement procedure was very simple and straightforward, however getting the battery shipped from Germany to my country was a quite the challenge. I've looked at some Xiaomi robot vacuums and the guy in the store told me that a battery replacement requires "professional maintenance" and that the battery compartment "purposefully locked down in order to prevent users from getting in there and messing it up". Pure nonsense. It's one thing to quote official, laboratory specifications, an entirely different thing the real world experience. *Without a proper battery replacement option your device effectively turns into e-waste. Better to look into it beforehand.*
