What spider is this in Idaho?
I'm just about 100% certain that this is a Hobo Spider, which belongs to the species Eratigena agrestis. As stated in my comment, the blemish on the vacuum cleaner's plastic makes it difficult to observe the full pattern on the spider's abdomen, which would have otherwise made for a much quicker identification. 

Once realized though, the distinguishing feature for me was in fact the pattern on the abdomen. If you look at the picture I provide and consider at the abdomen, it looks like a face with two eyes, a mouth, some hair, and a beard; i.e., a hobo. Now look at the picture in the OP -- the exact same "face" can be seen, excluding the right "eye" of the hobo (our left), due to the blemish on the vacuum's plastic. The "hair" at the pedicel, the down-turned "mouth", and the "beard", are all visible in both images, and are near perfect matches. The legs, overall body coloration, size &amp; proportionalities, and slight discoloration on the cephalothorax, also match.

I had to maximize the OPs image to 200% zoom to get a detailed enough view of the spider to then make these conclusions.



This species spider is most commonly found in your region, that being north west USA, however, they've also been seen in Asia and Europe. And as for if this is a venomous spider (since you're concerned about your daughter): according to Wiki, this kind of spider doesn't bite unless forced to defend itself, and, the CDC does not consider it to be dangerously venomous.
