Had many years of service out of my Xiaomi 1C which seems to be pretty much the same as this one just older.
The only reason it failed is because at some point I reset the maps and it kept getting stuck under my one couch that had sagged over time and therefore damaged the left wheel.
It's for this reason I would highly recommend spending a bit more and getting one that at least has Lidar and therefore doesn't only operate by "bump dynamics" and can actually "see" your couched and things and therefore actively avoid them.
I bought might without Lidar specifically because it's lower thinking that's good it will go under stuff that the taller ones can't but this was a mistake on my part.

You don't want to be spending another R3000 in a few years because the thing is too dumb to figure stuff out for itself.
