Features of Lefant M501-B Robot Vacuum Cleaner
Continually ready for cleaning
The sweeping robot immediately returns to the charging dock when the red light flashes to indicate that the battery is low or that the default cleaning is complete, so it is always ready for the subsequent cleaning.
Quite Clean
Improved internal airflow design reduces noise while maintaining a quiet operation that won’t interfere with daily activities.
For safety, use anti-collision
The sweeper slows down and gently touches the surface as a result of full-body integrated anti-collision sensors to prevent bumping into and damaging your furniture and other objects.
Sensors for safety
The sweeper itself and your family are adequately protected by built-in anti-dropping sensors on the bottom to prevent tumbling down stairs and off edges.
Keep the air pure
Three layers of filters—a primary filter, a sponge filter, and a HEPA filter—prevent dust from reentering the air. There is no need to routinely empty the trash because the dustbin’s 0.6L capacity suffices.
LCD control through remote
choose the suction level (low middle high), start working, schedule cleaning, and so on. Directly operate the robot (up down left right).
Large Runtime
The cleaning duration is up to 110 minutes with a 2600mAh high-capacity lithium battery, which can run for around 5 hours on a single charge.
High Success Rate
The M501-B vacuum robotic has a unibody design, which significantly enhances stability and lowers the failure rate when compared to the first generation’s mechanical design (which included flexible front sections).

To automatically clean the entire floor, press the start button.
- Cleaning Spots
Repeat the cleaning process in a small area until it is thoroughly cleaned

FAQs of Lefant M501-B Robot Vacuum cleaner
If I want the unit to cease cleaning, how do I get it to go back to the charging port? I tried pressing the remote’s home button, but it just keeps going?
First of all, make sure the charging station is positioned against a wall free of obstructions. 3.4 feet on either side and 6.7 feet in front. Second, please ensure that the distance between the remote and the robot is no greater than 16.5 feet while returning the unit to its home using the remote controller. Please feel free to contact the business at lefantrobot@gmail.com if you have any additional queries.
Do the brushes in the vacuum tangle up with rug fringe?
Yes, it will put a stop to it. It functions properly even if you sweep it under the rug.
When cleaning, can the vacuum manage fringe on rugs?
Yes, this device is really powerful and frequently topples my real tree.
This lithium battery has how many watt hours?
I have a 3/2 and it cleans my entire house with enough power, therefore I have no idea how to get replacement components.
Sorry, I’m not sure.
Le Robot app functions perfectly, but there is no Alexa skill for it. The Smart Life app only controls on/off when used with this with Alexa, though. help!
To control your M501-B, uninstall Le Robot and download the Lefant Life App. Please be aware that the connection to Alexa presently only has the ability to be turned on or off; however, our engineers are hard at work developing further functionality.
In which nation was it produced?
YES, IT WAS MADE IN SHENZHEN, CHINA.
