Product Description

Today iRobot filed a motion for a preliminary injunction against SharkNinja over three iRobot patents: (1) U.S. Patent No. 9,921,586 (selected room cleaning); (2) U.S. Patent No. 9,550,294 (recharge and resume technology with mapping); and (3) U.S. Patent No. 9,492,048 (auto-evacuation technology). 

iRobot also filed a complaint for patent infringement involving three other iRobot patents, spanning core iRobot features such as the Roomba i7+ robot's roller technology and modularity.

Today's lawsuit against SharkNinja follows iRobot's win of an exclusion order against multiple respondents at the International Trade Commission.

    Your review states Roborock S4 app has a feature of multi-floor maps. Can you provide step by step instructions to activate the feature?

      Hi John,
      in the left bottom corner, press the round button and select the «Edit map» in the menu (check the screenshot below).

      Worth to mention that this feature is very limited currently. It can store three maps: current, manual backup, and automatic backup. I didn't have the opportunity to test this feature, but I've found on Facebook a good description of how it works:
