Is it for you

Buy it if

  • The grime line along your baseboards never seems to go away
  • You want maximum spec for the money and will manage the trade-offs

Skip it if

  • You need a fast local repair rather than a mail-in one
  • App stability and translation quality bother you

The mop pad slides sideways out of the chassis when the robot tracks a wall, so the line along the baseboards gets covered instead of skipped. The reason people still mop after running a robot is almost always that edge, and this is the design aimed straight at it.

The numbers are the most aggressive in the class. The service story is not: a repair is a mail-in RMA rather than a counter visit. Whether you can be without the machine for that long is the real decision here.
