This document describes the ONSON J20C Robot Cleaner, a robotic vacuum designed for indoor use.

Function Description

The ONSON J20C Robot Cleaner is an automated cleaning device that can sweep and vacuum various floor types, including flat hard floors and carpets. It is designed to navigate and clean rooms, automatically returning to its charging dock when the battery is low or cleaning is complete. The robot can be controlled via a remote control or a mobile application (APP).

Key functions include:

Automatic Cleaning: The robot can initiate cleaning automatically and will return to the charging dock for recharging if the battery is low before cleaning is completed.
Fixed Point Cleaning: This mode allows the cleaner to concentrate on sweeping a specific local area by rotating outwardly in a spiral with a diameter of about 1m, and then spiraling inwards to the starting point. In this mode, suction is increased for better cleaning of the desired location.
Border Cleaning: The robot sweeps along the edges of walls and furniture legs to ensure comprehensive cleaning.
Random Sweep Mode: The machine operates in a random pattern to cover the cleaning area.
Suction Adjustment: Users can adjust the suction strength during operation using the remote control.
Scheduling: The cleaning time can be set and scheduled using the remote control, allowing for automated cleaning at specific times.
Pause/Resume: Cleaning can be paused and resumed using the robot's button or the remote control.
Boundary Strip Compatibility: The robot recognizes and avoids areas marked by a boundary strip, preventing it from entering blocked-off zones.

Usage Features

Quick Start:

Charging Dock Setup: Connect the charging dock to its cable storage box and then to a wall socket. Place the dock against a wall on a leveled flat ground, ensuring 2m free space in front and 1m on both sides. The charging dock's light should be on when connected to power.
Side Brush Installation: Install the side brush by slotting it into place until a "click" is heard.
Power On: Turn on the power switch located at the bottom of the main engine (1 for on, 0 for off).
Activate Product: Place the robot onto the charging dock, aligning the metal charging contacts. A series of tones will confirm successful activation, and the power button will illuminate.

Operation:

Starting Cleaning: Press the power button once to wake up the cleaner, then press it again or use the "AUTO" button on the remote control to start automatic cleaning.
Pausing Cleaning: Press the pause button on the cleaner or the remote control. Press again to resume.
Turning Off: Long press the power button until the lights go out. Turn off the power switch at the bottom if not in use for a long time.
Remote Control Usage: Install two AAA batteries in the remote control, ensuring correct polarity. Aim the remote control at the J20C sweeper for effective operation. The remote allows for auto clean, direction and time setting, clock setting, fixed time point sweep, random sweep, start/pause, reservation to sweep, sweeping along the side, and suction strength adjustment.
Boundary Strip: Use the provided boundary strips to define areas the robot should avoid. Cut the strips to the desired length and apply them flat on the floor or under an area rug using the supplied adhesive tape.
APP Control: The product can be connected to a mobile APP for operation; refer to the APP guide for details.
