Can I pick up my Roomba and move it to another room?

For the sake of it, yes you can pick your Roomba up and move it to another room. But this will surely confuse your Roomba. Newer models of Roomba map your house plan and floors. They remember and recall all the obstacles, furniture, and stairs in the room they are cleaning. If you suddenly and manually move your Roomba from one room to another it will start bumping into obstacles trying to figure out the layout of that room. 

What does the red light on Roomba mean?

If the red light is sweeping downward around the CLEAN button, it means the dirt bin is full and it is time to empty it. Your Roomba will not start cleaning again if its dirt bin is full. The dirt bin should be emptied after every cleaning session. 

If the red light is blinking around the CLEAN button, it means that the charging is too low to restart the cleaning task and the Roomba needs to recharge its battery.

Should I unplug my Roomba when not in use?

If the “not in use” period is less than a week, it is advisable to keep your Roomba plugged in and docked at the Homebase. If you are going on a vacation and not planning to use your Roomba for weeks, then you should unplug your Roomba, remove the battery and store them in a cool and dry place.
