It looks very modern, airy, and "hip". I will admit I would love to come there and experience your store even though I'm way too broke to even afford anything in it but a bottle of water. lol. Maybe add a couple of cafe tables in the middle or by the windows for people to sit at and discuss vacuum features and sales paperwork? I hear that's trendy now.
The vacuum shops where I live are all 20-30 years dated in decor and are converted bi-level Craftsman houses with additions tacked on. Very small cramped and cluttered. Not that there is anything at all wrong with that, I love it, as it reminds me of my own house. Here's the shop my family uses for vacuum repairs: https://www.yelp.com/biz_photos/gnc-vacs-south-bend
