Amazon robots and so worth it! My favorite since I need to mop my hardwoods often is the Yeedi because it get a deeper clean with the spinning brushes than the others. Still vacuums while mopping. If you need more vacuuming or pet hair pickup, the Roborocks are the way to go! The S7+ auto empties itself for up to 60 days! The S7 MaxV is automated to the max but comes with the price tag to prove it. The E4 is a fraction of the prices (under $200) and still gets a maintenance clean done. You have to put the mop part on each time you want to mop and vacuum #LTKGiftGuide
