Inspired by this video, I'm curious if a robot can do bedikat chametz for you.
The video shows a rhumba with a spoon and candle roaming around the house cleaning the floor. (Granted, the spoon and candle are not needed other than making the video funny.)
O.C., from what I recall, says that prior to Bedikat Chametz, the home should be essentially chametz cleaned, mostly. The custom is to place 10 pieces of bread in various places around the home and search for those pieces, while searching for other chametz.
Assuming that the rhumba goes into every room in your home, gobbles up dirt and crumbs on the floor as well as all 10 bread pieces, and at the end of its cycle, you open up the cleaning bin to verify that it actually got all 10 pieces - any problem with letting it do the work? Or, must you do the physical inspection, or at least watch exactly where the machine is going?
