I recently bought an LG Roboking robotic vacuum cleaner and thought I’d write up a review of it, and perhaps clear up some misconceptions I’ve seen online.

The version I got is the LG Roboking VR6171LVM, which is the second newest Korean model at the moment. The Roboking is sold under the name LG Hom-bot in a few European countries, but not here in Sweden.

I’m way too lazy to do that. This is where the Roomba enters the picture. It’s a robotic vacuum cleaner that offers to do the dirty work for you. The Roomba has its limitations but I’m glad I bought it. … Continue reading
