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

May I know Roomba 650 able to go to room by room to perform cleaning? Does it comes with Lighthouse?

For all robot vacuum can works out room to room or go anywhere into corner. Unless you close the door.

Roomba 650 to 770 does not come with lighthouse function.

Since it can work room to room, why still need a lighthouse? Any special for the lighthouse? You have the stock for Roomba 650?  Thanks.

Lighthouse has more advance function to guide Roomba from compartment to other compartment, for each compartment on 30 mins and go to next room.

If it is large space then you need lighthouse for clean out much efficient

Thanks. Do you have stock now? Roomba 650.
