My Robot Vacuum Cleaner is Afraid of Sunshine


I have a cheap WiFi enabled vacuum cleaner. One morning, I barked "ALEXA! CLEAN THE HOUSE." The gynoid immediately responded with "Now playing songs by Crowded House." The future's ace, innit?

So I opened the cleaner's app, hit a button, and heard the sound of a domestic-droid doing its thing. For two minutes. The app spat out this fabulously helpful warning.

Error message saying Cliff is abnormal

I trundled downstairs to see what precarious sinkhole the mop was teetering on the edge of. Only to be met with this.

Cleaner in sunlight.

My cleaner snoozing in a little puddle of sunlight like a domestic cat! Weird. I pressed the button and it refused to move. I gave it a little nudge, out of the sunlight, and it started up again! Only to get confused moments later...

I observed this happening a few times. The robot gets genuinely bewildered by stark differences between light and shade. To the point where it will follow a shadow thinking it is a wall.

This is a £130 cleaner - it doesn't have fancy multi-sensor AI with a Machine-Learning neural network. It's barely above the if-else-then level of "intelligence". But, to us lousy meat-brains, it appears to be intelligent. It backs away from walls, it doesn't clean the same bit twice, it knows how to return to its charging dock. So when it does something "stupid" it hurts our mental model of how this thing works.

This is the fundamental danger of AI. When confronted with ambiguous input, does it react the same way a human does? When overwhelmed, does it carry on regardless or ask for help from its superior?


This happens to other people!

    We ended up taping over our "cliff" sensors on our Roomboid. We have a carpet that's just textured enough that it thinks it's about to take a tumble down the stairs when it tries to vacuum parts of the living room, so it would often get stuck in the middle of the room. Ever since then, no problems, even though I'm pretty sure I'll be convicted of heinous crimes when the robots take over.

    Give it a bit of leeway, after all so many children are terrified of their shadow until they mature enough to realise what it is. The technology is still in its infancy. I've never even taken my Vileda version out of the box. 😉

    Has anyone had a brush and sensor error at the same time? I can't get mine to work. Before this issue it's been 3-5 stars only because it knocks debris around in Harswood flooring.

    Mine suddenly move very fast forward 2 sec, then move backward 2 sec then forward and back again and again in round so after few minutes it still remains in a same area. Im wondering how to reset it but no idea how to reset it. Anyone have any idea?
