Thank you everyone for your suggestions. I ended up buying the Dyson V8 directly from Dyson on sale for 249$. I looked into Costco but they only had higher price tags for higher end models. I originally was looking at the V15 but I feel like the V8 was going to be enough for myself and my two kitties. I took into consideration what was said about batteries and when my battery finally gives out i will definitely replace the battery versus buying a new one.
