Not Stealing Jobs, Stealing Time Back: A Defense of Purposeful Robotics

“Civilization advances by extending the number of important operations which we can perform without thinking about them.”

• Alfred North Whitehead

I’ve been putting it off for a while for the category to mature, but I finally took the plunge. I got my first real robot, a robotic vacuum we call DJ Roomba. People are rightly worried about robots displacing workers and wiping out entire categories of jobs. But then I realized this robot would be vacuuming and mopping my floors every week while I… what? Stood there holding a mop handle, emptying dust bins in the trash, wondering if I’d gotten under the couch yet? That’s not a job I’m going to miss; instead, that’s a chore I’m happy to delegate. And that’s when it hit me. This little black disc with mops, brushes and lasers is what automation should be. It’s not replacing jobs (we don’t employ any house cleaners) or stealing livelihoods but freeing us from the repetitive tasks that use up our time and energy. It gives us hours to spend on things that really matter, like family, creativity, rest, or even just stepping outside to touch grass while the robot works its way around our dining room table.

What My Robot Does

I’m not going to mention the model I purchased, this isn’t an ad. But it is a vacuum and mop combo equipped with LiDAR (Light Detection and Ranging technology — freakin’ lasers!) that maps its environment and has no cameras, an important feature for my privacy purposes. The first time I set it loose, it explored our home, room by room, building a detailed 3D map of every wall, doorway, piece of furniture, and exposed wire. I could see our entire floor plan, the dining room table, the living room couch, even the dog beds in the corner. But it wasn’t bumping randomly into things like some confused Roomba from 2005. It seemed to be thinking about its path (I know it’s just processing an algorithm but aren’t we all?). The robot would calculate efficient routes, moving in neat parallel lines across open spaces, then carefully navigating around chair legs and into corners. It remembered where everything was, and on subsequent runs, it would execute its cleaning plan with confidence.

When I was researching options, a key feature for me is integration into my completely local smart home setup because it means no cloud is required and no data leaves my house. Through Home Assistant, I created voice commands using Whisper for speech recognition and a local Ollama installation with tool-use capabilities, meaning I can tell it to “clean the kitchen” without that request leaving the local network (Amazon, Google, Apple — they don’t get to hear me). The same Ollama server powers vision capabilities for our home security cameras, analyzing video feeds locally to tell me when a package is sitting on the porch or a family of racoons is raiding our trash. Everything stays within the walls of our house: the robot’s map, my voice commands, even what the security cameras see. It’s automation with my agency in mind, not some corporation’s. Smart devices are feeling more like surveillance devices these days, so there’s something satisfying about a robot that’s genuinely working for me, processing everything on hardware I control, cleaning my floors while also respecting my privacy.

How Intelligent Is a Robot Vacuum?

So how intelligent is my new robot vacuum, really? To answer that, I turned to Max S. Bennett’s fascinating book “A Brief History of Intelligence: Evolution, AI, and the Five Breakthroughs That Made Our Brains.” Bennett argues that intelligence evolved through five distinct breakthroughs over hundreds of millions of years. The first breakthrough, around 600 million years ago, was steering, which is when early bilaterians (the first animals with bilateral symmetry, like simple worms) developed brains capable of integrating sensory information to make a single navigation decision. That’s it, just one decision, but one that would ultimately unlock intelligence for us. These primitive creatures could detect food gradients in the water and steer toward them, or sense predator chemicals and steer away. They were learning to categorize the world into “good” and “bad” and move accordingly. That’s smart, right? The original Roomba vacuum cleaners were modeled after this exact bilaterian template. My robot vacuum, with its LiDAR sensors detecting walls and furniture, and its algorithms deciding which direction to turn, uses a similar fundamental intelligence that first emerged in ancient ocean worms. It steers with purpose, integrating multiple sensory inputs into coherent navigation decisions.

The second breakthrough came 500 million years ago with the first vertebrates, who developed reinforcement learning, which is the ability to repeat behaviors that led to positive outcomes and avoid those that didn’t. Through dopamine-driven trial and error, these early fish learned which sequences of actions led to food and which led to danger. My robot vacuum demonstrates this too, on some level. Over multiple cleaning cycles, it refines its understanding of which paths are most efficient, learns where it’s likely to encounter obstacles, and adjusts its behavior accordingly. It’s learning in a real, measurable way and its behavior gets better, more efficient over time. My robot vacuum operates at roughly Breakthrough #1.5 level intelligence. The basic intelligence required for navigation, for moving through space with purpose while learning from experience, is ancient and powerful. And now that same intelligence is cleaning my floors while I write this post. The same breakthrough that allowed the first worms to find food in the ocean is what allows my robot to find its way under the bed.

The Sensorimotor Intelligence Angle

There’s another angle to this robot’s intelligence that fascinates me: the robot’s sensorimotor intelligence. If you’ve followed along with me, I often reference the importance of sensory information and motor action on/in the world. It has what we might call a “body” (motors, wheels, brushes, a physical form that moves through space) and it has “senses” in the form of its LiDAR scanner, cliff sensors that prevent it from falling down the stairs, and bump sensors that trigger when it encounters something unexpected. But the important part is linking these information sources together. The robot creates what researchers call sensorimotor maps, which are spatial representations that connect what it senses to how it should move. When the LiDAR detects a wall two feet ahead, that sensory information gets mapped to a motor decision, either slow down, prepare to turn, avoid collision, etc. It’s using its senses to build an internal model of space that’s tied to its actions. It’s the same idea that allows you to reach for a coffee cup without consciously calculating the trajectory of your arm. Your brain maintains a sensorimotor representation that links visual input directly to motor commands.

This sensorimotor approach is like Jean Piaget or Jeff Hawkins’ Thousand Brains Theory, which proposes that our neocortex contains about 150,000 cortical columns, each building its own model of the world using map-like structures and reference frames. We don’t have one unified model of reality, instead we have thousands of specialized models that vote and reach consensus. My vacuum is much simpler, in that it builds essentially one spatial model of my house, but that single model is sophisticated, using the same basic principle of map-like structures to represent space and navigate through it. And it operates in a similar continuous loop of sensing the environment with LiDAR, updating the internal map, planning the next movement, executing that action, then sensing again to see what changed. This combination of perception and action, of sensing and moving, is what defines sensorimotor intelligence. It’s not thinking about philosophy or composing poetry, but within its domain of navigating physical space to achieve a cleaning goal it demonstrates a form of embodied intelligence that took evolution hundreds of millions of years to develop.

What It’s NOT (The Consciousness Question)

Let me be clear that this robot is not conscious, not sentient, and it’s not going to wake up one day and decide it wants to write poetry instead of vacuuming. I think consciousness is a philosophical puzzle we’re not close to solving, but I know my vacuum doesn’t need it to do its job well. It has exactly one goal, hardcoded and unwavering, to clean the floors, rugs, and carpets. It experiences no desires beyond this directive and no existential dread about the meaninglessness of repeatedly cleaning the same rooms. Unlike my two dogs, who eye the robot with suspicion every time it leaves its home… I mean, dock, the vacuum has no emotional response to anything. And that single-minded focus is exactly what makes it useful. When it completes a cleaning cycle and goes back to recharge and clean itself, that’s not a win for the robot. The robot doesn’t care. It can’t care. But it’s absolutely a win for humanity, for robotics, and for the idea of building machines that competently handle specific tasks, so we don’t have to. Sometimes the most powerful tools are the ones that do exactly what they’re designed to do, nothing more and nothing less, without the complications of wanting anything else. And if it scares the dogs, it doesn’t have any intention to.

Robots as Augmentation, Not Replacement

Beyond vacuuming, are robots stealing our jobs? Robots have been deployed in factories for decades and they are being deployed for tasks that are repetitive, unpleasant, or very dangerous. It’s work that humans would rather not do anyway. In aviation, robots now paint aircraft wings, a job that used to expose human workers to toxic fumes while requiring them to perform the same repetitive motion thousands of times. A robot can apply a coat of paint to a wing in 24 minutes, something that would take a human painter hours in a hazardous environment. But humans are still essential. They load and unload the paint, oversee the process, troubleshoot problems, and make judgment calls that no robot can make. The robots didn’t eliminate jobs; instead, they eliminated the worst parts of jobs, the parts that break down human bodies and spirits over time.

In my case, we don’t employ housekeepers, so no one’s livelihood was threatened when I brought this robot home. But we spent a lot of time every week pushing a vacuum and mop around, time that added up to dozens of hours a year of tedious work. Now? That robot handles it while I can go outside, run errands, work on writing projects, or take the dogs for a walk. I think this is augmentation: the robot doesn’t replace me; it amplifies what I can do with my finite time and energy. It efficiently handles repetitive tasks, freeing me to focus on things that require what robots still lack, like human creativity, emotional intelligence, abstract thinking, the ability to look at a problem from an entirely new angle, or comfort my son who’s had a bad day. While AI and robots can complement human abilities, they cannot replace the messy, unpredictable, deeply creative work of being human. Thus the goal shouldn’t be robots that do everything we do, but robots that handle hard work so we can be more fully ourselves.

The Win for Everyone (Except Maybe the Dogs)

So, who wins when a robot vacuum joins the household? For me, it’s reclaimed time and mental energy. It’s not just the hours of physical work saved, but the mental load of remembering to vacuum or the guilt when I don’t get to it quickly enough. That cognitive burden just… disappeared. For my household, it means consistently clean floors without anyone having to nag or negotiate about whose turn it is. The robot runs on our schedule, quietly and without complaint, maintaining a level of cleanliness that makes the whole house feel more pleasant. It is exactly what robotics should be: tools that serve us, that handle well-defined tasks competently, that integrate into our lives without demanding we reorganize everything around them. For the robot itself? Well, it doesn’t care. It can’t experience satisfaction or pride. But if it could, I imagine it would be content. It has one job, it does that job well, and at the end of each cycle it returns to its dock having accomplished exactly what it was designed to do. That’s a kind of existential clarity most of us can only envy. And for my dogs? They’ve drawn the short straw, I’m afraid. Every time the vacuum gets ready to do its job, both track it with suspicious eyes, occasionally barking at it when it gets too close to their territory. Sorry, pups. The robot’s here to stay.

Technology should give us more life, not less. It should expand our capabilities, free our time, and enhance our connections. It shouldn’t surveil us, manipulate us, or turn us into products to be monetized. My robot vacuum, with its local processing and privacy-respecting design, embodies this principle. Everything happens within my home network, including the mapping and voice commands. No corporation is collecting data about my floor plan, taking pictures of us, or listening to my family’s conversations. I have control and I have privacy, because I insisted on building my smart home that way. The vacuum doesn’t want to have dinner conversations with my family or help my kids with their homework. It doesn’t aspire to write novels or compose music. It does one thing, and it does it well — it keeps the floors clean. And in doing so, it gives me back hours every month to do the things that matter to me. The vacuum is technology done right. It’s smart enough to handle its task, integrated easily into my home ecosystem, quietly competent, and always in service of human flourishing rather than corporate profit. That’s the model we should be following as we build more robots and AI systems, not asking “what can we replace?” but “what can we free humans to do better?”

Conclusion

My robot vacuum is simple and honest about what it is. It possesses some intelligence, the ancient capacity for steering and learning that first emerged in primitive worms 600 million years ago, refined and implemented in modern sensors and algorithms. It has one goal and that’s to clean the floor. No hidden agendas, no aspirations beyond its singular purpose. And when it completes its smart sweep of the house and back to its charging dock, that chime it makes isn’t the sound of a job being stolen. It’s the sound of a human being free to do human things, to play, to create, to rest, to connect, to think, to feel, to be present in ways that matter. Maybe instead of fearing robots and AI, we should be building more machines that are competent within their domain, purposeful in their design, transparent in their operation, and in service of letting us be more fully human. Not robots that replace us, but robots that remind us of what’s worth doing in the first place, and then quietly, efficiently, handle everything else for us.
