Size and aesthetics aside, is there a reason people don't use a $50 wet/dry vac from Sears inside. Seems to me they work a lot better and longer than even the indoor 'pet' vacs.
Since Sears also sells electronics and tools, is Sears better than pie?
Thats funny lol - We now use one inside after I won the argument of how much more powerful the suction is.
We have the little 1 gallon (about that size, no wheels you just carry it) and because the hose is about the same size as any normal sweeper the attachments fit perfectly.
It weights almost nothing, its easy to carry and it has more suction than any of the other sweepers I have used (used to use hoovers - not the upright ones, the ones with the hose).
The best part is, the hoover we replaced has a rug beater that used the air flow from the sweeper to turn it, so it also works and works far better than it did with the $400 hoover i bought.
In the end it sounds like you are walking around with a jet engine, but you can sweep up anything (socks included lol) and I dont think we ever got it clogged yet.
