Not sure the area Mike mentioned is anything that can be used.

caution: cables unlimited liquidated 2011. Out of stock many places. Used ones Amazon.
Reviews noted line of site short distances only (similar some wireless video devices). Web comments product category never sold well.
But -- if the only contact needed is to initiate a Neato run at the base...
(though why can't it have a cable in and just pull off it going out? a robotic unplugger? assumes manual plugging back in is acceptable, say when emptying)
Another category is WiFi access pt adapters to ethernet -- use with Ethernet to USB adapters. No direct WiFi to USB except as WiFi network hosts, wrong end. Connect enough junk...
The host includes 15 kΩ pull-down resistors on each data line. When no device is connected, this pulls both data lines low into the so-called "single-ended zero" state (SE0 in the USB documentation), and indicates a reset or disconnected connection.
A USB device pulls one of the data lines high with a 1.5 kΩ resistor. This overpowers one of the pull-down resistors in the host and leaves the data lines in an idle state called "J". For USB 1.x, the choice of data line indicates of what signal rates the device is capable; full-bandwidth devices pull D+ high, while low-bandwidth devices pull D− high.
