Sweeping the floor is cheaper and can be done at any hour, walking on old carpet especially kicks up dust and even after vacuuming it feels kind of gross (probably because I know it hasn’t been washed). Non-carpet floors are also easier to actually clean (or just wipe up spills etc), at least where I am where the air isn’t super-dry.

I’m with them, a throw rug would be fine so long as you can still pick it up to clean it elsewhere. Though I’d still rather just use a broom.

Also, cold floors doesn’t bother me but wearing socks/slippers instead is a nice option.
