The battery on my RoboVac 11 went bust right out of the warranty period even if it probably had ~15 recharge cycles on it. Bought a replacement (~30E) and the vacuum is happily chugging along doing a good job. This being said I assume Eufy is saving money on that front so I'm not entirely sure my next purchase will be from them.

so I take it the battery is user replacable? That's my worry with most of these electronics, the product can be fine, but if the battery is welded in place, then it becomes a huge PITA to replace.

Easily, one screw and a lid away on this model [0]. Phones are a bit harder to work inside with the constrained space and far more delicate parts (screen, screws, etc.). Maybe for a vacuum this is a lot harder to achieve even if manufacturers insist on it.
