I didn't know got Roomba thread here in Lowyat. Of all places in hobbies section

Parents recently bought the 780 model, coz the house so big it became too difficult to clean all the floors. Amazing machine I would say! Very very smart can go back to its 'base' after it finish the job. Can find its way under the bed, table and chairs and get out safely.

If got a some issue,it is that our TV table is too high for its sensor to detect and too low for it physically go under it. Ended up stuck and have to be 'rescued'. So have to use the virtual wall to stop it from going near the table.
