3 BROKEN Robot Vacuums - But Can I Fix Them? I bought 3 broken robot vacuums from eBay to see if I could fix them. All three were Roomba vacuums and there were several different problems including one with a weird vibration/noise and one that had an error 31 issue.

The non-gaming repairs are quickly becoming my favorites.

The sensor error could be from the optical sensor under the vaccum that detect if the the vaccum is about to fall in a void like a staircase. When I put my roomba on a very dark rug, it's going backward like yours did and then it's giving me an error because the optical sensors think the rug is a void.

Roomba S9 had a manufacturing defect in some earlier production runs. It worked for a few weeks, then have random issues. Reset, it would work for a little while longer, then stop again. Always Error 31. Support never said which part was bad, but replaced the entire unit because it was defective straight from the factory.

the tip on those rollers are different is because they are from a chinese knockoff.
If you check amazon reviews, it is well documented.
your fix you did is what is usually done.

I have a first generation Roomba that had a similar problem where it would only operate backwards then error out. The issue was a "cliff sensor" wire had come out of the wire race in the bumper and was cut when the robot bumped into objects repeatedly. Try inspecting the sensor wires, these late generation Roombas are really easy to tear down and diagnose compared to the very early ones.

I love how this dude basically shows us tutorials of how to do process elimination of fixing things and also makes it so he can have things for his house

[TheCodr]

Aww man I really thought these fixes would be a "clean sweep" 😂

Congrats on passing 1 Million subs!! You deserve it! Always love the content!

Love the roomba repair videos. Please do more of these repairs.

[Rahlal]

Love your videos <3 It's great to see alot of these old electronics get a new life, while also educating people on how to fix them for themselves.

[ItsSpecialEdd]

lol i love how you posted this a few days after me and my dad worked on ours (still broken) lol

[Evergreen]

That's cool that you're branching out! I'm surprised at how modular these things are. Do they even tell you what error 31 actually is?

I just fixed a water damaged Shark IQ for a friend of mine. Replaced a $0.42 SS14 Schottky Diode and it was as good as new. The water droplet shorted it to ground causing the diode to conduct in both directions.

Was very interesting to learn how the bump sensors do the job. Thanks, Steve!

[DOPESMAGA]

Love your videos! Great repair. I'm convinced 90% of repairs are just taking things apart, giving them a good cleaning, and telling them that they are loved.

[ozbarron]

Great video once again. Keep up the good work, love your knowledge on appliances

[mtshark]

2 out of 3 ain't bad Steve. Nicely done!

[RavenWolfRetroTech]

The ultimate in YouTube mastery! You made the sponsor message interesting!

I have a Roborock s5 and it's very well engineered and works extremely well.

At minute 8:07 on the chassis there is a metal thing that acts like a spring sort of...and it is getting weak, because of that the bumper stays closer affecting the sensors( I think .). I fixed my Roborock S7 by pulling that thing forward and putting some packaging foam behind it to keep it from going weak again . Considering that you changed and tried everything else this might be the cause.
