As a person who is a self-confessed techie, I have an onslaught
of electronic devices in my home. A fair share of these devices require
batteries, and over time it can be quite expensive to replace. Also, it is
inconvenient for those times when the batteries die at the most inopportune
While batteries can be justified to power electronics that are
mostly portable (ie. cordless phones, remote controls etc), there are many
devices that would be a lot better if they had a plug-in option.
Cue in Jarvis, my newest recruit to the household. My Roomba
660. I had low expectations about his cleaning prowess at the beginning, but he
quickly proved me wrong. My Roomba has become an invaluable member of my
As most Roomba owners will agree, to optimize roomba’s cleaning
there involves a great deal of Roomba-proofing the home. In the first couple of
months of using Roomba, Im learning new ways of how it usually gets stuck. If I
were to hazard a guess, it makes it cleaning rounds in the apartment and docks
back to charge, 50% of the time. Sadly a low percentage of automated success.
The other 50% of the time requires hide-and-seek on my part to drag it back to
the dock. While there are multiple areas in the apartment that attract the
little robot to its demise, this instructable relates to an issue where
bumpers, weatherstrips and unicorn extenders fail
I recently made a purchase on a Herman Miller Aeron chair that I’ve
been holding out a loooong time for. (I thought that 7 years of ‘wanting’ this
chair was justification to purchasing it). Problem is my Roomba is constantly
getting stuck in between the legs/casters of this chair. The shape of the Roomba
and ‘burrowing’ behaviour ends up wedging it beautifully between the Aeron’s
The Roomba 660 included an auto virtual wall. But it requires 2x
C cell batteries to run. This is a mod on how to convert it to use AC power. This
mod does not require permanent alterations to the integrity/structure of the

Step 1: Materials needed
1. iRobot auto-virtual wall
2. 3V AC adapter
3. Electrical tape
4. wire cutters
Step 2: Prep the AC adapter
Purchase a suitable AC adapter to power the virtual wall. The wall takes 2 C batteries, so collectively it takes 3V to run. I luckily rummaged through my junk and found a power adapter for my Gameboy advance (I just aged myself), that was spot on at 3V. More likely than not you will probably have old electronics devices that you can salvage for this project. Otherwise I believe The Source carries AC adapters with variable voltages for reasonable prices.
Step 3: Open up the battery compartment in the virtual wall
Step one seems easy enough, but from reading threads and searching youtube allegedly this is a rampant issue where the door is difficult to open. So much so that there is a full video on youtube specifically on how to open the door (I originally thought it was a gag video).
Either iRobot made amendments to the door design for my model, or I have superhuman strength, but I personally had no issues opening the compartment.
Step 4: Remove 4 small screws from top of battery compartment
**this step could be optional if you have dexterity and small hands. The idea is to place secure the positive and negative wires of your AC adapter to their respective terminals within the housing. I found it a lot easier to remove the housing, to secure the wires to the terminals
Step 5: Test functionality before reinserting the battery compartment back into housing
