$4 iRobot Roomba 800 & 900 Series Rubber Brushes

Amazon has the iRobot Roomba 800 & 900 Series Multi-Surface Rubber Brushes for $4. Shipping is free with Prime or on orders over $35.

This is significantly lower than the typical retail price of about $33, with the previous deal at $6.50 indicating strong value at this price point.

Given the product's usual market value and the price drop, we consider this a good deal, especially for those needing replacements. The deal makes the normally ~$33 product available for a fraction of the cost, which is a notable savings for compatible parts.
