I have been waiting for a long time for the Flex XCE. After seeing the Mille I’ll probably jump on this. I like all the features of the Mille.
I would like to see a comparison of the two but guess that is not possible...
I've been waiting to get the 3401 but now that the XCE is coming out I'm going to wait to buy it. Hopefully more info will come out in the following months.
I can tell you what I used to get the cat pee smell out of a home rug. Use lots of baking soda and vinegar (rinse dry and repeat a couple of times). If it can get cat pee smell out it can get out the vomit smell.
Of course it's hard to do this method on carpet without being able to pull it out...
