Using Your RoboVac
Important Tips Before Use
a. Remove power cords and small objects from the floor that may entangle RoboVac.
b. Remove rugs that are thicker than 0.87 in/22 mm as they may cause RoboVac to malfunction. Fold tasseled edges of area rugs underneath to prevent tangling RoboVac.
Do not use RoboVac on long-pile carpeting.
c. Avoid cleaning spaces lower than 3.9 in/100 mm to prevent RoboVac from getting stuck .
d. Keep RoboVac away from wet areas.
e. RoboVac may climb on top of objects less than 0.67 in/17 mm in height. Remove these objects if possible.
f. Anti-drop sensors prevent RoboVac from tumbling down stairs and steep drops. They may work less effectively if they are dirty or on reflective/dark-colored floors. It is recommended to place a physical barrier to block off problem areas where the device may fall.
