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 !!!


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.


Something about this really tickled my fancy. Following the path of Spot/Void the roomba as it carves elegant curves and straight lines across the chaos of assumptions is a delight, and is oddly satisfying.


If you like visera cleanup detail, house flippers, or anything else of that ilk, then I suggest giving this a whirl. It's good, clean fun.


My only feedback for the author would be that (aside from one memorable incident) there's been no mentions of bathrooms, or things that occur in them. The human character eats and drinks, but never uses the bathroom. Am I saying this just because I want to expose Spot/Void to the horror of wizard bathrooms? Maybe. ... And by maybe I mean: Yes. Yes I am.

This is a wonderful, leasurly peice of story telling with some God-tier world building going on in the background.

Our two central characters are each adorable and admirable in their own ways and I am desperate to find out where this is all going. I love the comittment to the ground level view point of Spot and the consistant way that Bee thinks her way out of the various missunderstandings.


I don't know if this was written to be read to children, but that's how I started reading. A chapter to my kids at night... Except then I read ahead, I needed to know how it continued! And we're all laughing at how silly it is, but it's really just a really good, fun read.


I've really enjoyed reading this story. Its mostly unique take on the isekai sub-genre is great and a lot of fun. The author does an amazing job making a roomba interesting, despite the fact that it's just a vacuum cleaner. The humor is great as well, and only gets better as the story goes on; I often found myself chuckling, or even outright laughing at the comedy. It's also a great example of non-human done right.

The prose is good, and has just the right amount of detail to really suck you in,—heh, suck—without having you stumble over excessively detailed descriptions of clothing and people. The POV jumps around a lot between Spot, Beatrice, and sometimes some other person., but it works really well, and it's always clear who's head we're in. It never felt forced or obtrusive and I always felt like it was worth reading, unlike POV swaps in some other stories.

The grammar is good. There's an occasional mistake, but it's usually just a spelling mistake or an accidental extra period at the end of a sentence. The sentences and paragraphs themselves read well, and I didn't encounter any problems with awkward phrasing.

The story so far has been rather lighthearted and fluffy with a good dash of comedy. It's nice, but like most of those stories, it can leave you wanting for more. Like eating cotton candy, it's sweet and delicious, but not very filling. It's still a lot of fun, though, and has some signs it is changing into something a bit more serious., so I'm looking forward to that.

Other than that, I found myself skipping over some of the paragraphs from time to time. Mostly some about cleaning, since they were a bit repetitive. They absolutely can be fun and interesting though, and they often are, but not always. The author is actually quite great at making cleaning entertaining. If only it was so much fun in real life.

Spot/Void is a great example of a non-human lead done right. Its entire world is the floor and cleaning it, and that reflects really well in its dialogue and thoughts. Spot doesn't have much personality, aside from cleaning, but that's fine. Its way of viewing the world is what makes it special, since we get to see this new world through its sensors. Spot experiences some growth as it realizes he isn't bound by his original rules and capabilities anymore, but personal growth isn't really the point of his character.

Beatrice, however, has a lot more personality, and she's great. Her mostly unfounded fear of Spot can be annoying, but nothing you can't read past. It's really interesting to read both their accounts of the same events since they both have such a different way of looking at things. Beatrice is also the character through which we learn the most about the world.

The other side characters we occasionally see are also good, but I don't think they're interesting beyond what we learn about the world through their eyes

This story is definetly worth a read if you're looking for something new and interesting, or are a big fan of non-human leads.


I thought this would be a ridiculous story that made for a bit of light fun. I was right, but I'm so interested in it! All the little things Spot doesn't understand but we do makes for great dramatic tension! And I'm genuinely invested in how clean the castle is.

Every word of this makes me smile. Easily the best chapter titles on RR. If this is ever available on Kindle, I'm buying it. Or, even better, if this ends up as a video game, I'm buying it. I'll definitely hop on again later for a more in depth reading and review, but for now just wanted to show a bit of support for some genuine fun. Thanks for writing!


The dumbest concept I've ever read.

Reviewed at: Chapter 31: Letting it Soak

This masterpiece is dumb. Its brilliant. It makes me wonder if Sheogorath has somehow crossed into our dimension to twist the mind of this stories readers. This is cozy fantasy at its best. A fantastic parody of the isekai genre, while at the same time wholeheartedly embracing it. 

If you are at all familiar with isekai, self inserts or OC inserts, you have to read this story. It is incredible.
