If you don't buy this online and decide to order from irobot store, may I suggest you try it first, you won't be disappointed! If you are getting error codes, go online and find out what the codes are. They are fixable. If you get Error 7, Roomba needs to be charged. Just remove the battery and clean the contacts or silver parts that the battery sits on and it will most likely work fine. I have 3 robot vacuums and use them mainly to keep floors clean. Once a week on Saturday I pull out the big vacuum cleaner.
