Customers scan the QR code using an app, then pay for the wash with PayPal. One can imagine finding one at a gas station, or alongside bike parking. "We have sold two machines this year," says Kumar, "and have been on a road show in different cities in Germany where we cleaned over 3,000 bikes this year."
