Review on Dust Box Door Latch for iRobot 🗑️ Roomba 500 600 700 Series Vacuum Cleaner Accessories by Jessica Lewis

I ordered this item expecting to receive a complete unit that includes a small spring part that holds the latch on the Roomba dust collector. I have the latch but not the little spring piece to hold it! I really need that detail to keep the latch from falling out. Please advise where I can purchase a small pen holder (similar to the pen that holds the watch strap). I appreciate your help with this matter and intend to purchase more replacement parts from you in the future.
