My Roomba is scheduled to start cleaning my house every day at 7 AM and continues to run once I've left for work. Sometimes, it gets stuck on something or lost, and sometime it does not start due to a full bin, dead battery, etc.

I will consider a job completed if the Roomba runs that day and ends the job docked at its home base. I will consider it not completed it the Roomba doesn't start, or if it ends the job anywhere other than being docked at its home base.

I will also comment how many total jobs it completed each weekend.

I will not bet on this market.
