If you have mostly hard floors and want weekly mopping convenience, yes. If your home is primarily carpet or you don’t mind mopping separately, the Roomba 705 Max gives you the same vacuuming power at a lower price.How does the Combo 4020 avoid getting your carpets wet?

The Combo 4020 is smart enough to recognize when it transitions from hard floors to carpet and automatically lifts or disengages its mop pad so it doesn’t drag a damp cloth across your rugs.So you’ve been eyeing a robot vacuum for a while, and now you’re standing at a crossroads almost every first-time buyer faces: do you grab a solid vacuum-only Roomba and call it a day, or do you spend a little more for a model that vacuums and mops
