Is it worth it?
The Betboyles V75S-2 makes the most sense for a buyer who wants one machine to handle daily dust, pet hair, and light mopping on hard floors without paying for a premium robot ecosystem. Its appeal is straightforward: 2200Pa suction, a 400ml dustbin, a 250ml water tank, app and voice control, and self-charging in a slim body that can slide under low furniture. The trade-off is that this is a practical cleaner first, not a precision floor-care robot, so the mop and navigation behavior matter more than the marketing language around them.
I would put this in the “good budget helper” lane for apartments and busy homes with mostly hard flooring, low-pile carpet, and pets. Skip it if you need a robot that scrubs dried messes, handles cluttered rooms with zero babysitting, or gives you the confidence of a more advanced navigation system. For the right home, it can take a real amount of routine cleaning off your plate; for the wrong one, the limits show up fast.
