This Saturday I had the opportunity to stop by La Shed Du Fred in Callicoon to look at their custom furniture. They make amazing pieces out of reclaimed barn wood and non-toxic finishes.
Irregardless as we were chatting with the owners it came up that it was difficult to find people to clean the store. I suggested they look into buying a Roomba as they could set it to run in the evening after the store closes.
It would be a simple and easy way for small retail shops to keep their stores clean. Sure you'd still need to dust items, but the floor could be vacuumed every night.
Next time I visit to order our dining room table I'll bug them about getting a Roomba.
