A part counts toward a year only when its maker states both a price and an interval. A part with either missing is listed and left out of the total, never estimated. Prices are list prices.
Questions
What readers ask
Why is a total marked with a plus?
Some of that robot’s parts have no maker price or no maker interval, so they are listed but not counted. The real total is at least the number shown.
Does any of these need a subscription?
No paid plan was found for any of the four. The Narwal, eureka robot and Roborock app listings on the US App Store show no in-app purchases.
Are these list prices?
Yes. The page uses list prices only, so the totals do not move when a store changes what it charges.
