Common questions
Does this guide cover a plumbed refill-and-drain dock?
No. Select the separate Refill and Drainage System guide from the manufacturer’s support page for that version.
Where does cleaning solution go?
Follow the solution-cartridge instructions for this dock. The guide warns against adding it in a way that creates an excessive concentration.
What should I check if the robot will not charge?
Check that the dock has power and that its charging contacts are clean and dry. Use the charging troubleshooting section for the remaining checks.
