Important Tips before Use
Remove power cords and small objects from the floor that may become
entangled with the T8.
The T8 may climb on top of objects less than 0.63 in/16 mm in height. Remove
these objects if possible.
Do NOT stand around narrow places, such as thresholds and aisles, to reduce
the uncovered rate.
The T8 will clear all memories and re-plan all work routes if it is manually moved
or it is controlled by the remote control during cleaning. To ensure it works
efficiently, please do NOT arbitrarily move T8 manually or operate it by remote
control during cleaning.
Anti-drop sensors prevent the T8 from tumbling down stairs and steep drops.
They may work less effectively if they are dirty or used on reflective/very
dark-colored floors. It is recommended that physical barriers are used to block
off areas where the T8 may fall.
Please make sure all furniture is properly organized so that the T8 is able to
clean well without becoming stuck.

Visual Localization helps the robot remember its location
and the planned route after full charging. It resumes
cleaning with the original coordinates generated by the
Visual navigation system.

environment(at least one round), the vision module
establishes the current 3D image of the environment.At
this time, pause the robotat the Location A then move it
to the Location B, and press the Control button to restart
the robot.
Now relocalization is launched,the Visual SLAM algorithm
work out the exact Location A based on the existing map.

to visual navigate.If it succeeds,the robot voice
prompts"Localizing is succeeded,resume plan cleaning",
the robot will navigate to the Location A and resume
cleaning. If it fails, the robot voice prompts “Move into a
