MT1 -- Support Manual
AI-powered autonomous sweeping robot for large-scale indoor environments, designed for dry debris collection in warehouses, factories, airports, and transport stations.
Page 1: Overview
What is the MT1?
The MT1 is a professional autonomous sweeping robot designed for large-scale indoor environments. It focuses on sweeping and collecting dry floor debris -- paper shreds, plastic film, dust, and other loose material -- from hard surfaces in warehouses, factories, home improvement centres, airports, and transport stations.
The MT1 uses a combination of two side brushes and one main sweeping brush to collect debris into a large 35-litre dustbin. It navigates autonomously using integrated LiDAR and visual SLAM, following pre-mapped routes and returning to its charging station automatically when battery is low or a task is complete.
Unlike the CC1 range, the MT1 is a dedicated dry sweeper. It does not mop, scrub, or use water. For environments that need both sweeping and wet cleaning, the MT1 can be paired with a CC1 or CC1 Pro for a complete cleaning solution.

Page 7: Cleaning Modes and Functions
Sweeping Operation
The MT1 is a dedicated sweeping robot. It uses two side brushes to sweep debris inward toward the main sweeping brush (roller brush), which collects debris into the 35-litre dustbin.
Designed for: Environments with significant loose debris such as paper, plastic film, dust, and light materials on hard paved floors.
Cleaning width: Approximately 70 cm with both side brushes installed.
Working Modes
Manual: Raise the handle and push the robot along the desired path. Control speed and direction manually.
Automatic: Position the robot near the visual positioning marker. Select the task on screen and start. The robot follows the pre-mapped route autonomously. Lower the handle before the task begins.
Speed Settings
The MT1 speed range is 0.2 to 1.2 m/s (adjustable). Higher speeds cover more area but may reduce debris pickup on heavily soiled floors. Lower speeds improve collection quality. Runtime varies from 4 to 8 hours depending on the gear setting.
Additional Features
Autonomous Charging: The robot returns to the MT1 charging station automatically when battery is low or after completing a task.
Dust Removal Handle: Located on the side of the robot body. Repeatedly pulling this handle dislodges dust from the air filter without removing it. This is a quick maintenance step for use between full filter cleanings.
Detachable Screen: The 10.1-inch LCD screen can be operated handheld or attached to the handle, providing flexible control options.
App Control: The MT1 supports mobile app connectivity via 4G, Wi-Fi, and Bluetooth for remote monitoring and task management.
Page 8: Dustbin and Air Filter
Note: The MT1 is a dry sweeper and does not have a water system. This section covers the dustbin and air filter -- the primary consumable systems for dry sweeping.
Dustbin
- Capacity: 35 litres -- significantly larger than the CC1's 2.5 L bin, designed for large-area sweeping with heavy debris loads.
- Contents: Paper shreds, plastic film, dust, and light dry debris.
- Location: Accessible from the rear or side of the robot body.
Emptying the dustbin: 1. Power off the robot. 2. Remove the dustbin from the robot. 3. Empty all garbage. 4. If needed, wash with clean water. 5. Dry completely before reinstalling.
Air Filter
The MT1 uses an air filter to clean the exhaust airflow and prevent dust from being blown back into the environment.
Quick maintenance (dust removal handle): 1. Locate the dust removal handle on the side of the robot body. 2. Repeatedly pull the handle in and out. 3. This creates airflow that dislodges dust from the filter. 4. Perform this every 2 weeks, or more often in dusty environments.
Full filter cleaning: 1. If the handle method is not sufficient, remove the air filter for thorough inspection and cleaning. 2. Rinse if needed and dry completely before reinstalling. 3. Replace the filter if it is damaged or permanently clogged.
