Longevity and durability of QRevo line?

We just ordered the QRevo Master the other day. It ran its first full clean and we are pretty happy with the results. We’re just getting used to all of the features, but it seems like it’s going to help us accomplish our goal of keeping the floors clean with two kids and two pets running around.

Given that this device was almost $1000, I’m naturally thinking about it as a long-term investment. I’m curious for those who have owned Roborock devices (especially QRevo) for the long-term, do they last? I’m a little concerned that the warranty is only one year but if these devices are generally lasting people a long time, I’ll feel a lot better.
