> On October 16, 2026 none of the robot vacuums we follow is really cheaper than in the 30 days before at the same store.

- As of October 16, 2026
- A deal is a price at least 5% and $10 below what the same store usually asked in the 30 days before (the median of its daily prices), at a store we followed on all those days.

Today no robot is really cheaper than in the 30 days before at the same store. That is normal: stores mostly lower their prices around sales such as Black Friday.

Today we can judge 0 of the 39 robots on sale. For the others we have not followed the store with the lowest price for 30 days yet, or that store had a price on too few of them.
