Roomba Error 15 (2023)

We’ve all been there. You’ve just sat down to enjoy your morning coffee, and suddenly your Roomba starts beeping like a truck backing up. That’s Roomba Error 15 for you. But don’t worry, I’ve got you covered. In this article, we’re going to dive deep into what this error is, why it happens, and most importantly, how to fix it.

In case you weren’t aware, Roomba Error 15 indicates a problem with the Roomba’s bumper sensors. But before we get into the nitty-gritty of Error 15, let’s briefly talk about the science behind these sensors.

The Roomba, like most smart robots, utilizes infrared sensors located in its bumper. These sensors work by sending out infrared light and then receiving the light reflected back. This way, the Roomba knows when it has bumped into something and needs to change direction. Now, Error 15 pops up when the Roomba thinks the bumper is compressed when, in fact, it’s not. In short, the sensor’s got its signals mixed up.

Common Causes of Roomba Error 15

There are a few reasons why your Roomba might be giving you Error 15, and some are more common than others.

Firstly, debris can interfere with the bumper sensors. Dirt, dust, pet hair — you name it. If something is blocking the sensor, it might mistakenly think the bumper is compressed. Secondly, the Roomba might just be a little confused. Sometimes, it just needs a bit of a reset to get back on track.

Lastly, the issue could be more serious, like a hardware malfunction. This could be due to prolonged use, wear and tear, or even just a faulty part.

How to Fix Roomba Error 15?

Don’t fret if your Roomba gives you Error 15 — there are several solutions to this problem.

Start by giving your Roomba a good clean. Pay special attention to the bumper and its sensors. A gentle wipe down with a clean cloth should do the trick. Remember to unplug your Roomba before you start cleaning, and be careful not to damage the sensors.

If cleaning doesn’t work, try resetting your Roomba. Unplug it, wait for a few minutes, and then plug it back in. Sometimes, the good old “turn it off and on again” trick works wonders.

But, if you’re still having trouble after cleaning and resetting, it might be time to call in the pros. Reach out to Roomba’s customer service or take it to a professional for repair.

The Role of Bumper Sensors in Roomba Error 15

We’ve touched on this a bit already, but let’s delve a little deeper into how these bumper sensors are involved in Error 15.

The bumper sensors play a crucial role in Roomba’s operation, helping it avoid obstacles and maneuver around your home. When they function correctly, they inform the Roomba when it has bumped into something. But when they’re not working right, they might think the bumper is compressed, even when it’s not. That’s when you’ll see Error 15.

It’s important to remember that while bumper sensors are sophisticated pieces of tech, they are also sensitive to dirt, dust, and other foreign objects. This sensitivity is a double-edged sword — while it helps the Roomba navigate your home, it also makes the sensors susceptible to errors if not properly maintained.

Preventing Roomba Error 15 from Recurring

The best way to deal with Error 15 is to prevent it from happening in the first place. Here are a few tips to keep your Roomba running smoothly and Error 15-free.

Regular maintenance is key. Regularly clean your Roomba, focusing on the bumper and its sensors. Make sure there’s no dust or debris that could interfere with the sensors.

In addition, try to keep your Roomba’s path clear of small items that could confuse its sensors. If you have pets, clean up any fur or feathers that could find their way into the sensors.

Lastly, handle your Roomba with care. These robots are durable, but they’re not indestructible. Be careful not to drop or handle it roughly, as this could damage the sensors or other parts.
