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 either robot need a subscription?
No paid plan was found for either. iRobot’s Select lease, a different product, closed to new members in May 2024. The SharkClean app is a free download.
Which parts does Shark price at its own store?
Shark’s page lists a pre-motor filter at $14.99, a water mesh filter at $14.99, a 2 L multi-surface cleaner at $11.99, a battery at $107.99 and a base tank at $25.99.
