To be fair, potions cost twice as scrolls, in return for being easier to use. But then scrolls are super cheesy themselves and you could remove them from the game, leaving potions, wands and staves for spell items, and nothing much of value would've been lost.
I would agree. I haven't seen all that many potions in years.
There's many, many, many enemies against which Super Cleaner will be completely worthless (aka non-casters non-martials).
Cleaner 9000 will almost always hurt.
Well, everything that has armor/clothes is vulnerable. One negative level isn't so bad compared to having to re-equip a bunch of equipment in the heat of battle. Removing spell buff works against those casters are buffing and those using magic items to get a buff as well (though encounters using magic items are rarer), though that's still pretty minor considering the power of actual dispels.
Derp, completely messed up the prerequisites.
Looks good now. Should the anthropomorphic animal use the same Extra Option feat progression system since they are similar? Right now it can skip right to the last ability tier.
A boat would just be an object with swimming and carrier.
It wouldn't make it a better swimmer like flying abilities offer the flying objects. That aside it would be more of a submarine since boats float and swim is also underwater.
House reminds me that I forgot to add the ability to protect people inside. Will probably make it an upgrade of carrier (it's not like you're big enough to count as an house before that).
Good thought. As for the size required to contain people... it depends on the size of the occupants. Dat doll-house!
Animated food... You do realize that living creatures already are moving meals, right? An human doesn't have any special ability to represent the fact it can provide nourishment to that ogre. 
Living creatures are food though they are not mechanically treated as objects, which do get weird powers for being stuff, such as the shrink rayslam.
The CAB (Coalition of Animated Bananas) will never accept your tyrannical regime's attempts to break its ascension to ultimate fruit power!
I kid. It's quite all right as is. Nothing stops a player from playing a fried chicken kung fu master. Anom nom nom.
Dangerous Container (OO2)Now that I think about it, should it have a some kind of requirement such as being a (alchemy) container or having some kind of link to the elemental breath damage chosen?
X CustomShould this Omega Object ability also give Arsenal IV options and arsenal progression, like Zero Machine, since pick both is impossible?
Pure ConstructionWhy does it mention a shield type per size? It only counts as having an armor of that kind.
Also, for materials whose effects are based on the armor's AC bonus, what is supposed to use since it is only treated as having an armor. It doesn't actually have one. Mostly for base armor abilities like Gold or even Mercury.
Object Abilities in generalI notice that, much like the feats, as currently written, a OO class ability allows you to select two picks of the lower OO ability tier (or 2 OO1 from OO2). This only allows it to pick from the list of the tier directly below it, which means you cannot, for example, trade one OO4 for four picks of OO2, only two picks of OO3, because the option to get lower tier abilities is not part of any tier's ability list but of the class ability itself for each tier independently.
The topic discussed previous leads me to understand that OO abilities are meant to be able to get traded all the down to a bunch of OO1 abilities. Is it so? If it is, is it supposed to be the same for the feats?
