LG reckons customers are turned off by the thought of having to empty their vacuum cleaners. Thus their designers have created a tower-like dock for their CordZero stick vac. When you dock the vacuum, it not only charges, but a secondary vacuum inside the tower empties the stick vac's contents into a bag.

We've seen this trick before with robot vacs, when iRobot's Roomba i7+ came out. That was five years ago, and robot vacs have been around a lot longer than that--you'd have thought they would've taken over by now, yet the cordless stick vac continues to thrive and evolve; which means the robot vacs aren't very good, or have hidden UX hassles, or a large chunk of the market prefers manual vacuuming.

It would also seem, if LG is correct, that consumers can't tolerate touching their own dead skin cells. "All the yucky stuff gets stored inside a dust bag inside the tower," says LG. "All you need to do is replace the dust bag every now and then." The price for this convenience is $700, plus $19 for a three-pack of replacement dust bags.

I suppose products like this are a boon for those with dust allergies or respiratory issues. But for the rest of us, this seems like an awful lot of gear to get the floor clean, plus you've got to live with this tower-like thing in the room. And as I always wonder with tech-heavy objects, what do you do when something in it breaks?
