Right now, highly-rated iRobot Roomba robot vacuums and Braava mops are up to 50% off at Amazon. There are also vacuum and mop bundles, including the Roomba j5 and the Roomba j7, to tackle two chores at the same time which helps you save time. Some models have even been marked down to their lowest prices of the year.

You can tell this self-emptying robot vacuum when and where you want it to clean — and Amazon has it marked down to $330, from $599, only if you shop now.

Amazon said on Tuesday that it will host its Prime Day-like sales event, "Prime Big Deal Days," on October 8 and 9. Amazon will hold Big Deal Days in Japan later in October. It has also prepared a holiday gift guide.
