With the all black interior of the 2015's Fit I purchased this for $15 to clean the carpet and cloth seats whenever it needs to be.

12V Portable Wet Dry Outdoor Mini Car Boat RV Vacuum Cleaner Inflator Pump BT7 | eBay

My 2015 Fit is Mystic Yellow and the color of the Vacuum Cleaner matches the Yellow/Black theme. I have it stored in an open box along with the spare fluids and cleaning supplies in the cargo area.

 

I prefer weathertech floor mats and never eating or drinking (only water allowed) in the car. Less things to fly at the back of my head in an accident that way.

 

Weather Techs and Clazzio seat covers.
