My Roomba 500: upgrade and repairs

I run my Roomba 500 just about every day, so you can say that I'm a heavy user.  I like the Roomba series because it works well, it's reliable, and it is easily repairable if it breaks down.  My Roomba 500 has been in operation for 8+ years and is still running strong.

My Early Robot Years:

I have owned four Roomba vacuums over the years.  My first robot was a 2nd generation "Sage 4110" that I bought in 2007 for $160.  It was great, but I ran it hard.  One day I foolishly ran it through mud and water and it broke down. I tried to repair it, but I was an idiot and botched the repair. I'm not sure what happened to it, but I moved in 2008 and I don't have it any more. My second Roomba was a 2nd generation "Red" model, likely a 4100, that I bought around 2010 for about $100.  I ended up leaving it to my roommate when I moved to another state.

Roomba 500 series Repairs and Upgrades

I bought my Roomba 500 in 2012, and it has been running strong since then.  It has been very effective, but I have made some necessary repairs over the years

  • Power jack.  My power jack went bad.  Most people likely use the docking station and not the power jack.  Me too. But my Roomba was sure it was always plugged in, even when it wasn't, and it made it seem crazy.  The problem was that the little switch inside the jack had failed, leading the Roomba to conclude that a cord was always plugged in.  I ended up buying a replacement jack and associated wiring for about $10.  A little surgery and I was back in action.
  • Cleaning head. My Roomba's original cleaning deck went bad with melted gears, likely because I had Roomba deal with a lot of fine dust that worked its way into the gearbox.  In short, the original-style gearbox was not so great at keeping dust out of it.  Happily, I bought a new "updated" 2012-era AeroVac head which is better in EVERY way.  Even if your classic cleaning deck doesn't go bad, I very highly recommend replacing the 500's original cleaning head with the AeroVac head.  It's an easy drop-in replacement.
  • Battery.  I've replaced the battery twice.  They seem to last about four years.
  • "Dirt-dog" style waste bin.   This is an optional accessory that I bought.  The bin is a large capacity but filter-less waste bin.  It has high capacity, but no vacuum motor.  They don't make this any more, and it's likely because it isn't that great.
  • Brushes and Filters.  These are "maintenance parts", and so I've replaced them several times. 

In all, I think my Roomba is still great, even after all these years.  I did have a couple problems, but the upgrade to the AeroVac system made my Roomba far better.  I imagine the power jack problem is an uncommon fluke, since I met a long-term iRobot Roomba engineer (a friend-of-a-friend), and he had never heard of the issue. And he seemed to know everything.

Roomba Replacement?

The latest addition to my Roomba collection is a Roomba 960.  My house that is under refurbishment will use the Roomba 500, and will be doing dirtier work.

Dirt is what the Roomba does, but it definitely takes its toll.  I suspect that eventually I will have to replace the wheel assemblies, and do a deep clean of the optical sensors.  But for now, Roomba continues on its cleaning duties.

Fixing a SodaStream Jet, part 1: Disassembly Guide

I've had my SodaStream Jet for years, and once in a while something has gone wrong. Disassembly is the first step to repair.  Start with this article to see how to disassemble the SodaStream, and then once you have that down, scroll through my other articles to see how I repaired specfic SodaStream problems. SodaStream Jet Disassembly Guide Tools Required Flat head screwdriver Phillips head screwdriver 1. Remove the Carbonator.  Duh. 2. Remove the black panel lever The front big black tilt lever needs to be removed first. Removing this panel is tricky, but it isn't impossible. Looking up at the bottom of the black panel, there are two tabs, one on the left and one on the right. These tabs fully secure the panel in place. The trick is to use a flat-head screwdriver under the plastic to gently lever the tabs out of the way.  Note in the pictures how I approach these tabs with my screwdriver.  I usually release the left side first, and then I release ...

Macintosh: Upgrading an eMac

It's been a long time since I wrote this article, but the fact remains: The good old eMac can still be useful if you take the simple steps to keep it as good as it can be.  All can run Tiger, and most can run Leopard - great operating systems for their day with a bit of useful life.  This article describes the procedure I used to upgrade my old eMac, including: Replacing the internal hard disk with a large capacity drive. Increasing the memory for performance Upgrading the operating system Here I'm upgrading a 700 MHz eMac, but the procedure and tasks for upgrading other eMac models should be almost identical. Upgrading versus Replacing My sister's eMac is of the 700 mhz variety, with 256 MB of memory. The machine seemed to be getting "slower", and the original 40 GB disk was becoming jammed packed with photos and iTunes, and within a few months she'd be out of disk space. There were two options to address the problems: upgrade the eMac, or go o...

Excellent DD-WRT Router for Me: Netgear WNDR3400 / N600

My WiFi performance was suffering, and so I decided to do something about it and upgrade my router. When I say my WiFi performance was suffering, I really mean it:  I live in a large high-rise apartment building and there are 100+ WiFi access points visible from my home office.  All of the contentious traffic was severely curtailing my WiFi reliability.  I was lucky to get 1 Mbit/second throughput.  Sometimes I was lucky to stay connected even with my WiFi router in the same room. I decided it was time to go for 5 GHz, which is a WiFi band which is used less frequently and which has a tougher time traversing walls.  And of course I wanted DD-WRT support.  The set of features I was looking for included: Trouble-free DD-WRT support 5 GHz 802.11n Support Simultaneous dual band capability Inexpensive.  Maybe even cheap.  For me this means under $50.  Under $35 is even better! It sounds like an easy task to bring all this together: A...

Sodastream Carbonator Leakage, Usage, and Weight

SodaStream 60L "Carbonator" CO2 cylinders have a specific weight when empty, plus about 410 or so grams for the CO2 they should have when they're "full".  A little while ago I went to buy a replacement Carbonator from my local hardware store. The dealer pulled a new Carbonator out of the box and sensed it was lighter than usual.  He put the "light" Carbonator in the "empty" pile and sold me a different one.  At that moment I concluded that it would be smart of me to weigh both new and empty SodaStream carbonators.  Here are the results. Weighing a SodaStream Carbonator - for both Science and Consumer Protection.       The dealer told me that sometimes the carbonators leak after they leave the SodaStream filling facility.  That means there could be an opportunity for customers like me to get ripped off! The SodaStream cylinders I buy claim to have a net product weight of 410 grams - and that means that a full Soda Stream Carbonator shou...

MacBook: burnt out magsafe connector repair

My MacBook (A1342 model from 2009-2010) stopped working, thanks to a cheap knockoff magsafe charger. The magsafe connector looked burnt with heat-distorted melted plastic and some black carbon surfaces.  Plugging in the charger resulted in no lights and no action.  My MacBook was dead. First I tried to clean up the connector with some Q-Tips, tooth picks and solvent, but that did little, as seen in this "after" picture (below).   The heat generated by the aftermarket charger permanently deformed and distorted the MacBook's magsafe connector.  Clearly the damage was significant. Burnt Magsafe Connector - Replacement Required! Looking at iFixIt , I determined that it would not be difficult to replace only the magsafe connector with the right tools.  I hoped and prayed that the problem was isolated to the connector assembly and not the logic board. I bought a replacement magsafe connector assembly (available from Amazon) for under $20 and started to rep...

Fix a Lightning Cable with Heat Shrink Tubing

We've all seen a Lightning cable that has started to fall apart.  They get used every day, and after enough tugs and yanks on your iPhone, they start to fray. I've seen a lot of these frayed cables, so I've started to fix them before they break with heat shrink tube.  I get my heat shrink on Amazon, like this handy and inexpensive pack.   I prefer the heat shrink tubes without internal glue - it has higher flexibility and a smaller outside diameter once shrunk. Heat Shrink Tubing on an Old, Frayed Lightning Cable In the photo here, you'll see that I slid on a 1.25 inch length of heat shrink over the lighting connector, and then shrunk it into place.  I chose a diameter that just barely fits over the lightning connector.  In all, it took about 60 seconds to perform this repair. Warning: the white plastic of the lightning cable has a pretty low melting point.  It seems to start to melt at about 125°C (or about 250°F), which is the same temperatur...
