LG has a line of robotic vacuums called Roboking – they are pitched as being square shaped because your house it. I guess it’s a little bit of a dig on the round design of some of the other robotic vacuums on the market, and how they can miss corners due to their design.
Regardless of this one design difference, the people that buy these vacuums find them to be pretty good machines. They cost a little more than some of the competitors, but that different might be justified in some of the features you get. Stuff like better corner cleaning and digital bumpers can make a difference to some people when buying.
LG has another similar model on Amazon, called the HomeBot 3.0, which has a similar design. It’s fairly well rated.
