Title: Didn't last
Review: I have had a rarely used roomba 400 series for 4 years. It has not worked for the last year and I sent it in for diagnostic. Was told it needed over $200 in repairs. I've replaced the batteries 2 times and just can't spend any more money on a poorly engineered product. It was worked well when it worked but I certainly did not get much use out of it. As the roomba says, "Uh Oh".
Is the review positive or negative?
