I bought the brand new Bissell Crosswave Max to take care of my floors - I am partially disabled and would make cleaning so much easier. May I use it on this floor with the special formula for hardwood floors? Also, in a small, I mean small, home, does a narrower or wider plank look better?

Please reach out to Bissell directly, since the hardwood formula may not be the best choice for vinyl. They do carry a multi-floor formula that should work, but we'd recommend you talking to them directly since they'd know their product best. As far as the plank widths are concerned, it is totally your preference since both widths have their own charm, and some people just prefer one over the other. However wider planks are known to make smaller spaces appear bigger and are pretty popular at this time.
