Should you buy now or wait for Black Friday?
Our grade is an A+, the lowest price we've recorded, so this is a price worth buying at now if you need it. Today's $299.99 is the lowest price we've recorded. Black Friday could bring a lower price, but nothing in our records promises one.
What's a good price for the iRobot G181?
A good price for the iRobot G181 is $299.99 or less: the lowest of the 6 prices we've recorded from Jul 7, 2025 to Oct 26, 2026. Our rubric says a price at the bottom of an item's history, and not one that pops up every week, can earn an A or a B. Anything over $899.99 is above every price we've recorded, and our rubric gives a price above an item's usual range a D or an F.
Lowest recorded: $299.99 on Aug 2, 2026, Oct 11, 2026 and Oct 26, 2026 at Amazon.
