Chosen Solution
This happens on a daily basis, the screws used are supplied by the vendor. It started when I noticed one of the 3 brushes had been 90 percent torn off. I replaced the brush assy, screwed it back on, but I kept finding it and the screw unattached in the house. Its like the socket is stripped. Whats a gal to do? Also… The entire front wheel assy will easily drop out of the bottom of my Roomba, even if I pick it up! Why is this?
I wrapped teflon tape around the screw and it seems to be staying in for now.
If Roomba won’t help you, coat the screws with Loctite Heavy Duty Threadlocker to hold them in place https://www.amazon.com/Loctite-Heavy-Dut…
Sounds like your unit is either defective or encounters a lot of vibration so the screws don’t stay secured. I would recommend you speak with Roomba directly to see if they are aware of the screws loosing up as well as get the missing bracket and screws for your front wheels. Depending on when you bought the unit they may exchange it. iRobot
