Hi, I think it both is the same perform,

The only for LG Roboking we still unknown about the future parts support.
Cause of Irobot we trust the brand and durable problem.

The roomba have lighthouse to navigation of room to room system.
After completed the 1st of 30mins and entry to next room.

The LG can do more like mapping system can much easliy to empty the bin or dust on robot.
Just we worries about in future such as battery or any parts & accessories support.
Cause the LG is direct shipped from Korea.
But everything have to take on Time for do some research on parts.

If you would like to purchase on Mint Plus we will have some Discount of PNP.
Mint plus the main thing can work in dry or wet or wet wiped tissue, such as Maggic clean type.

Thanks

Hi, the lg Roboking mop is just slightly can do the wet function but not effecient like mopping robots.
Cause the mop case is only can fill in minor water and something no function at all.

If you floors already dirty and it mop over I can't imaging the dirty dust marks can be easliy apply it everywhere.

Thanks, the mint wet case still can fill in water for cover like one single room area or more.

Thanks
