How noisy is a Neato compared to a Roomba (which is pretty noisy)? Also, does it turn while it's moving forward/reverse or does it have to come to a full stop before it turns? I've noticed most products stop then turn. LG's current machines can all turn while navigating and are relatively quiet. They just don't have their latest products available in the US yet. And none at all in Canada (same goes for Samsung and some others unsurprisingly).

Based on the current usage patterns in this house, I'd like the device to go out cleaning during the night, let's say between the hours of 1am and 7am. I'd keep it restricted to the main floor which is currently all tile and hardwood.

Upstairs will be about 33% hardwood by the end of the month, but the rest of the wall-to-wall carpet will probably only go away sometime next year. I can see letting a robot loose upstairs once in a while, but it would probably be mostly regular vacuuming.
