iRobot Roomba 530 Robotic Cleaner

it's quieter than discovery and work better. Its accesorries are different to discovery series. I couldn't reuse the brush or battery of discovery. My old discovery was out of order in 4 month and I couldn't find a place to fix. The Irobot company doesn't provide to fix it. and I bought it 4 months ago but they said my worrenty was expired. I wonder why. I suggested me to buy new one with a low price but I didn't want to buy same one again. I hope the new model is better than discovery series. I bought a new battery and new brushes for fixing the old one. I spend over $70 for that. I like roomba very much but when it has a trouble I cna't get any help. The new one, Roombar 530, can be replaced every part. I wonder after I spend a lot of money to fix it by myself and I would get same result, buy a new one.
