This is a fun story about a roomba and his attempt to keep a magic castle clean.

Mostly a humorous slice of life story where the roomba Spot grows and explores. He's been slowly getting smart and stronger, so about fifty chapters in there's more exploration and interacting with others. Early chapters were almost entirely from his limited (and initially very simplistic) point of view but other character's chapters juxtapose what's happening more clearly. That mechanic seems like it's winding down now that he's close to human in understanding. It was well done and didn't get over used.

No issues with grammar, this is a well written and not too serious fiction. If you like the pun title names you'll probably enjoy the story.


...but fizzles out pretty quickly.

The first chapter of this story was incredibly well written. The concept of a bunch of demon summoners fleeing in terror from a Roomba they've mistaken for an archdemon is simply comedic gold. However, the rest of the story is just... kinda average. In the end it's the same joke repeated over and over, except it's not as funny because no amount of setup will make up for a lack of fresh and unpredictable punchlines.

Furthermore, we're 40 chapters in and there's no way to tell if the author is still trying to write a parody. The plot follows so closely the standard progression litRPG formula that it's indistinguishable from most stories on this website. There's nothing that makes this story stand out, and it makes no sense to call it "satire" when there's no clever subversion past the first chapter.

Overall it's decent, but definitely very formulaic.


I like the story so far, it's absolutely hilarious reading this from both perspectives. It shows promise so far, and the grammar, and characters are great. I've love to see one more development in the magic or the history of the world but I'm sure that will come as the story progresses

With funny ideas that depend on constant misunderstandings, it's best to keep them short and sweet.  I liked the first few chapters, but then the lack of dialogue and a plot based on misunderstandings began to feel thin.   When I realized the story was boring me, I dropped it.   This was a great unique idea for the first few thousand words, and then it became tedious.  Thanks for sharing, and best wishes on your projects.

What more do you need to know? This story is perfection incarnate. All hail the power of Spot the Roomba's name All hail the power of Spot the Roomba's name All hail the power of Spot the Roomba's name All hail the power of Spot the Roomba's name All hail the power of Spot the Roomba's name

This one is just a joy to read. It is funny, engaging and and well-written. It will probably not become an epic fantasy series, considering the main character, but I simply love the way the author plays with the misconceptions and different perspectives. It isn't a five-course meal of fantasy excellence, but it is definitely a nice satisfying snack. Read it when you don't want to invest a lot of brainpower, but still want to be thoroughly entertained.


Style/poise and grammar are impeccable. Not a spec of dirt in sight in these words - spot made sure to clean them up real good.

Jokes aside this is a roomba isekai. It heavily uses misconceptions for humor and spends a delightful amount of time detailing the struggles of a little bot just trying to clean things. You can tell the author owns a roomba - I don't think you need one to enjoy the humor but it definitely added to the experience for me.

The Story is a slice of life with a minor progression aspect. Theres a few alternative POV's that are mostly used for comedy but are well done. Personally I'm looking forward to any future mutations/growth but I'm also worried too many might break it from its currently well laid roomba roots. I'm stuck between hoping it never changes and knowing if it stays cleaning indefinitely the premise might grow stale.

The Character score is based soly on the roomba's internal monologue and viewpoint. I love it - I can imagine its what my own Roomba is thinking - and hope to see how it grows in intelligence and personality in the future.

Overall this is better than I was expecting - and I was expecting alot based on the name. I definitely recommend it for anyone who wants to read about an isekaied roomba


I admit I didn't expect much when I came across it, but I devoured all 59 chapters available in two days. Reading about a roomba leveling is oddly compelling. I can't wait to see what Void/Spot and Bee get up to next.

There's hardly any grammar or spelling mistakes. I look forward to this being published properly so I can buy it.


Yes, Bee (the human) and the roomba develop a genuinely good relationship. She recognizes that the roomba is a good... er, person. And the roomba cares about her by tucking her in bed and stuff. She at least understands its intentions with a simple yes, no system. Now it wants to learn more about the "squiggles" that are words and numbers to communicate with her better and just access more information. That adds new and exciting possibilities.

I like that this is still deeply connected to the original premise. The roomba's highest priority is still cleaning, and not suddenly too overpowered. After all, the outside world is too dirty for it and its wheels wouldn't do well at all. Its new skill called deep analysis or whatever gives a lot more data to the roomba, which results in better cleaning/combat/training predictions. But not too OP -- this is still a fragile plastic roomba, even if it can move super fast. At the very beginning, it rejected interdimensional travel and flight for an endless dustpan. Void (the roomba's other name) now sees how valuable the other options were, but still feels that the endless dustpan was right for its philosophy and it benefited it a lot in general.

I enjoy reading Bee's perspectives (not too mature or immature since she's 13-ish) and the perspectives of the humans scouting the castle to reclaim (?) it. They aren't massively threatening, so they don't cast a dark mood on the story.

There's also the mythical demon that Void just casually sweeped away the protections of. So it's going to awaken in a couple months it seems, or a year maybe. But that's treated as a future problem so the story still doesn't have too much tension for my tastes.


It has its funny and endearing moments, but it focuses mostly on character development by showing their thoughts, as well as action. Hence the slice of life tag. But I don't think this is satire... just a unique and consistent character in an isekai, where the rest of the elements play out like normal isekais.


When I started reading this on a whim, I had not expected I'd read more than 2 chapters; not even imagined I would get addicted to the story and read the whole thing (till now). The idea is absolutely unique and new, blending humour, action, adventure, irony, and so much more. Kudos to the writer, the story really deserves more attention! Would recommend this to everyone!

Style: Major POV is quite interesting with the MC being so naive and progressing in every way. Multiple other POVs also give a nice view. Informal tone and inner thoughts are frequently used and conveyed realistically. Well incorporated.

Story: Original and weird, yet extremely well put together. Various elements and themes are interwoven; The plot is thought out quite well no plotholes till now.

Grammar: 1 word: impeccable - Couldn't find a single typo and trust me I was looking. No idea how it's done so fast.

Character: Character building is quite detailed yet not boring at any point. Side characters are introduced and well-described. Realism is palpable with the erstwhile robot being believably innocent.

I could go on and on but I don't want to reveal the fun.

Seriously Try it! SPOT the DOOMBA is SUPREME !!!
