Why are all robot vacuums the same? They all have these tall as fuck charging stands.

I don't want to dedicate several square feet of wall space for a fucking charger and dust bin. What i do have, though, is a fucking couch with tons of free space around it. Instead of building the dust bin to go above the fucking robot, why hasn't ANYONE released one that is wide so it can go under a fucking couch or bed?

The fucking dock could be U shaped and the bin you remove to empty it would slide out forward instead of lifting up.
