The Lenovo E1L Robot Vacuum Cleaner is not an ordinary vacuum cleaner. It is a smart device that will replace you in your daily chores. The gyroscopic navigation system allows for the optimal memory of the cleaning path thanks to the built-in gyroscope. E1L will easily remember the layout of your house and clean it up faster the next time it is turned on. An upgraded sensor detects boundary sections to help the robot clean up areas that need it. This saves your time and doesn't hit other items unnecessarily. Four height sensors prevent the robot from falling down stairs or other heights. An intelligent security sensor with a 360-degree recognition angle will ensure that the robot will never get stuck (will not hang) even near beds, sofas and other hard-to-reach places. Thanks to the easy access to the dust container, you can empty it easily without making a mess. Powered by a 2600mAh lithium battery, the Robot Vacuum Cleaner E1L works for up to 120 minutes on a single charge, which means that all rooms in your home can be cleaned with just one charge.
