These cheaper bots can both mop and vacuum, but you'll need to manually configure them for either task.
The idea here is kind of clever: the robot comes with two bins, one that sucks in dust and one that acts as a water tank with a mop pad on the bottom.
You'll need to switch out the bin depending on which cleaning mode you want (the iRobot marketing team has come up with the phrase "swap and mop").
Neither model will be particularly "smart" about that, but the more expensive J5+ can map your home, and you can lay out "no mopping" zones in the app, thanks to a front-facing camera.
The cheaper i5 doesn't have as many sensors, and the press release says it's "ideal for smaller homes with mostly hard floor surfaces."
For all this talk of a "budget" bot, remember that this is iRobot, so everything is still pretty expensive.
