Query: Black & Decker 18 volt cordless handheld vacuum

I am 67 years old and find this vacuum too heavy for me to handle as I have arthritis in both of my wrists. I have to hold it with both hands and this is also hard to do. I also don't think it picks up dog hair like I wanted it for. I wanted it to mainly clean my car since I bring my dog with me. In fact if it is not too late I am going to be looking into returning this product.
