Ive a roomba as well - love it very much she cleans away all of the upstairs with no complaints (I got her 3 years ago for xmas from my husband!) Best pressie ever but I would def recommend taking out an insurance as mine has had to go back twice for repairs- once brushes slipping then faulty battery.
Apologies she has cliff sensors - doesn't fall downstairs & returns to her base.
