We’re doing a tire change for 15 Bucks.

If your Roomba just spins and spins in mindless circles, the problem might be her wheels.

We have a 700 Series Roomba and she had a case of the spins.  One wheel have zero tread and the other was completely gone.   Needless to say we had sticker shock when we when looking for new tires. If your Roomba needs a tire change here’s how. As with all directions, read all of this before you start.


Disassemble all the parts you would for a good cleaning.
Remove the side brushes.
Remove the battery.
Remove the bottom cover.
Remove three screws.
Find a RC shop and buy some wheels. 3 Inch diameter with no more than 1/4 inch tread.
I had to carve the rubber off the wheel.
Compare the wheel with the rubber.

You can get all OCD and measure the space on the wheel and mark off the tire.  I used the “Christmas Paper Method.

I eyeballed the center of the tread and then noticed the tread pattern where I’d cut.  Like Christmas paper. 

You might find extra rubber on the wheel side that will have to be trimmed.

Once again, the OCD method is to make it as flat as possible and scruff up the surface of the rubber for better adhesion.

Test fit the rubber on the wheel and make sure it fits in the lip of the wheel. Trim as required.
Use this glue. Don’t skimp.

At this point there are two schools of thought.  You can fit and glue the rubber to the wheel and not move the wheel.  Some feel than turning the wheel damages the electric motor.  While removing the old rubber from the wheel, I found out that you can turn the wheel until the cows come home. 

Apply glue to the wheel and glue the rubber on starting form the bottom.

Use drop of couple of drops, little by little until you get to the “top”.  “Top” shown above. I found the pulling the ends using Method One made for a better fit because the rubber gets skinny when you pull it and then fills the space quite nicely.

As you get to the top. Let it overlap and decide where you’ll make the final cut.

In a perfect world, the ends are cut to fit perfectly.  If you miss, pick through all that cut rubber on the table and pick a little piece that will fill the gap.


The other method of turning the wheel was what I used on the second wheel.  Scraping off the old rubber took about an hour.  But moving the wheel was much faster than Method One and did a better job of fitting and gluing. Pull the end of the rubber as you glue to make the rubber fit nicely but not too hard.  It’s not “Instant” Instant glue.  If you go with 45 second breaks between pullings you’ll be fine.

Reassemble Roomba.

HINT: We wash the roomba bin in the sink with dish soap.   Soon we’ll get brave and see if it’s dishwasher safe.  If you already know it is, leave that info in the comments below.

Don’t forget to bookmark this for the next time.  Leave comments on how your tire change went and add your hints as well.


How Do I Talk to a Crew Chief?

There are many times when it is necessary to actually talk to a Dedicated Crew Chief. You might be a pilot preparing to fly and want to know if the jet you’re climbing into is safe. You might be a new flight chief who never had the privilege of being a DCC and are trying to figure out how to make these people work. You might be MARRIED to a crew chief and trying to convince them beer and pistachios aren’t the only food that needs to be in the house.


At best in any situation is’t difficult to determine exactly what the crew chief is saying. To help you with this we’ve provided a short list of translations of commonly used phrases.
