Home Robot Parts Price Tracker

This tracker follows the published price of the same 18 home robot parts and service plans each quarter, from the same sellers. In the first check, in October 2026, robot vacuum batteries ran from $39.99 to $169.99, mower batteries from $219.99 to $449.99, and the main pool robot parts from $149.99 to $1,270.85.

First check: October 2026. Next check: January 2027. Each price is the seller’s listed price on the day we checked, with stock status as shown then. Sale prices are noted.

How the tracker works

The same listing is checked each quarter, so changes reflect the seller’s price, not a different product.
If a listing disappears, we note it and do not swap in a different one.
Prices are from US sellers, before tax and shipping.
Each brand page on this site has more parts and context.
