Some seek power. Some seek justice. Others seek to root out the filth lurking in the darkest of corners.

Spot was summoned from his comfortable charging pad and familiar floors to a world of magic and intrigue. After the flight of his new patrons, he is left to care for a filthy castle. During his quest to keep this new home clean, he will face demons, foreign armies, and the dreaded stairs.

All those who stand before him will be swept away. Those who follow his spotless trail will find enlightenment, purity, and a world on its knees.

Follow this wholesome vacuum on his quest to power.

Stories that start off with a ridiculous premise to fuel comedy often get boring after 2-3 chapters, as the novelty of being a roomba wears off and we start to consider the greater narrative. That's not the case here.

The author expertly manouvres around these pitfalls to weave a story that keeps the momentum up all the way through. If you'd told me that a 'roomba LitRPG' would be the next project I end up loving on this site, I might not have believed you - but damn, does the writer make it work for them.

Don't read if you're looking for a more serious narrative - as it is, after all, a story about a roomba being summoned by a group of cultists - but absolutely do if you're looking for something lighthearted.

Dang thats a cute cat

This shouldn't work. The author makes it happen.

There's a highly unique MC. There's is good world building. Albeit, not a lot, but the world building that does exist so far is highly effective, and I am sure that much more world building will follow. Read this, you won't regret it.

I am qualified to give this book a "LAUGHING WARNING" so I do.



~I'm the type of guy that likes to Roomba around~

Reviewed at: Chapter 12: On the mortality of dirt

This story is built upon a fun foundation of shenanigans caused by severe assumptions.

The usual machinations of kidnappers/summoners were foiled, for when they aimed to conjure a demonic entity, they instead brought forth one that upholds order for the comfort of those around them. 

They invoked... Spot.

Spot the Roomba, who is spotty on why most of the resident humans celebrated their arrival by making a mess of the place, exiting with great haste.

No matter, for it is time for a good cleaning sequence! These silly humans did leave the castle in quite the state, what with all of these circles of particulates on the floor...


Great story, MC Sucks (because Vacuum)

Reviewed at: Chapter 23: Power Washing

One of the better Isekai stories, unique perspective on the genre, and well written, also it's a story about a roomba that just wants to do rooomba stuff, and thats pretty neat. 

Worldbuilding is minimal, which works because the focus is very narrow, no need to worry about other things when they arent important, and nothing is important to the main character, because its a vacuum cleaner.

Excellent grammar and Style. the characters arent very well fleshed out beyond the main character, which is pretty shallow, but they fit their role, Story is basic and a slow burn, which at this early stage means not much actually happens.


I made an account just so I could give this story some stars, not that it needs them at this point. When I saw it on the rising list a few days ago, I thought for sure it would be a flash in the pan. How could a story like this really go anywhere? Well it does. This story really cleans up.


The idea and writing are quite nice, but I have reached chapter 15 already and still don't know why I should keep reading this. The initial interest because of the "crazy" idea wore off and now I don't see this going anywhere. The joke about the dangerous Roomba has run its course and nothing has come along to replace it in keeping my interest. It might be that there is some cool long game waiting for me but currently, I just can't get motivated about reading this anymore.


We've had a man turn into a vending machine, a girl into a spider and sentient dungeons... So why not a Roomba in another world.

All the Dust that Falls is a light hearted, comedic Isekai based around a Roomba who just loves to clean, and doesn't quite yet realize he's been transported to a dangerous world of demons and sorcerers.

The pacing, much like a Roomba, is slow and plodding but fits the story well as our protagonist slowly learns tiny bits about his new world in between the incredibly important task of cleaning. The humor is based around Spot's confusion at his new world and how he treats it like he would that of the normal home he'd been cleaning in the real world. The author has carefully been placing set ups for the future which keep you reading and interested even when Spot is cleaning the same old floor for the third time. Our female secondary character is also quickly finding her place in the world although some much lesser characters aren't quite there yet.

It's well written and manages to incorporate comedy well and any mistakes are being cleaned up in edits very efficiently. Progression and litrpg elements run throughout each chapter without becoming a boring list of achievements, skills and numbers.

Overall a super fun comedic Isekai that doesn't take itself too seriously.





I really enjoy reading it, the perspective of a roomba is weirdly wholesome and bee is cute ^-^ The Chapters from other Pov are also pretty funny and who they treat our Roomba. Im really interested to see where this will go in the future and what interesting powers he will get!



You always end up expecting parody stories to be funny for three chapters and then slowly becoming redundant and shallow. 
Well, that's not what this roomba story did. 
Not only the style fits the novel perfectly and the jokes are never out of place, but also the other POVs we are introduced to are rich and colorful. 
The story unfolds slowly and deliberately. The pace allows for a good view of the castle and hints of world building have emerged to keep the most curious at bay. There's not infodump, no force-feeding the readers the rule of the world: everything is narrated organically and presented at the best possible moment. 

For what concerns the characters, main character is hysterical. The maid, bee, is a perfect backdrop for the initial silliness, it provides enough gloom to have a perfect balance of fun and serious. 

If the author manages to spun the narrative well enough to make this more than just a parody, this could easily become a mainstay on RR's top comedy roster. And so far, he's succeeding. 

The grammar is good but it does sometimes switch to present tense when it shouldnt. Nothing a decent proofreader couldn't take care of. 



Some priests at a magic tower decide to summon some arch demon. Instead they get a sentient roomba. It likes humans, and sees them as its masters. It only wants to clean. 

We see several hints of a grander world. With a kingdom under attack which is why the priests was trying a summons in the first place. 

But we dont really care about those little plot points. Just want more Spot.
