roomba salvage?

hi all, i’ve been lucky enough to receive an older roomba (for free - friend bought a new one)… i’ve charged it and it makes an attempt to go (as well as lighting up), but gets only an inch or so - though the lights stay on… can i measure the battery current to determine if the battery should be replaced?..

or with it being no cost to me, should i just salvage parts?.. i suspect that there’s a gold mine of parts underneath the plastic on that thing… and a new battery is $70… oh, and i have a wife to keep the floors clean :D… God, i hope she doesn’t read that…


This page provides links on how to replace the cells in the battery pack:

no need to destroy a working robot for the sake of a dozen c cells.
