The Nexaro NR 1500 must be adapted to its environment—and the environment to the Nexaro NR 1500:

  • A responsible person (e.g., facility manager, cleaner) is appointed and trained to oversee the use of the robot vacuum cleaner. They provide on-site support in mapping the cleaning area, ensure a robot-friendly environment, return the robot to the docking station in case of an error, and empty the dust bin regularly.
  • The floor area is up to 400 m2 (gross area = total floor area including furniture, obstacles, manually cleaned areas under tables, no-go zones, etc.).
  • The robot has a maximum working range of 32 m radius around the docking station.
  • Free, open areas without typical large objects, such as walls or furniture, are smaller than 6 m x 6 m.
  • The cleaning area is a dry indoor area with hard floors or carpet, ideally with as few doors as possible (e.g., an open-plan office).
  • The cleaning area is not interrupted by stairs, escalators, or obstacles higher than 15 mm (e.g., door thresholds).

We recommend careful and thorough preparation for optimal cleaning results:

We recommend carrying out the initial mapping of the cleaning area using the AI mapping technology at a time when there is little or no foot traffic. Allow sufficient time for preparation of the cleaning area and generation of the initial map.

  • A mobile connection (2G or, preferably, LTE-M (“LTE for Machines”)) is available at the intended location of the Nexaro NR 1500 docking station. There is an outlet for the power supply at the location of the docking station.
  • The docking station must be placed so that there are no obstacles (e.g., furniture) within a distance of 0.5 m to either side. It must be positioned so that a freely accessible area extends 0.8 m in front of it.
  • If possible, position the docking station at the center of the overall cleaning area.
  • There are sufficient objects, such as furniture, within a radius of 4 m from the docking station to help the robot with precise zone-based cleaning. Ideally, the position of these objects will not be changed after the initial map is generated.


Robot cleaning area: Use the Nexaro NR 1500 to map the cleaning area and establish no-go zones to designate sensitive or complicated areas that the robot vacuum cleaner should not enter (e.g., desks with office chairs, meeting tables with chairs, and areas with numerous cords, floor outlet boxes, or similar obstacles). Make sure that the no-go zones extend a generous distance from the obstacles. These areas are to be cleaned manually by the cleaning staff (collaborative cleaning = division of cleaning tasks between staff and robot).
Stairs and fall-risk areas: To prevent the robot from aborting its mapping process prematurely when it detects a drop-off, we recommend placing magnetic strips at all drop-off edges and then marking them as no-go zones on the generated map. Once the mapping is complete, the magnetic strips can be removed again.

High-pile carpets: High-pile carpets and long carpet fringes can be wound up by the main brush of the Nexaro NR 1500. To prevent this, simply demarcate high-pile carpets in the Nexaro HUB using no-go zones. These zones are the responsibility of the cleaning staff, who will clean them manually (collaborative cleaning = division of cleaning tasks between staff and robot).
Glass walls and doors: Transparent and reflective surfaces can be invisible to the Nexaro NR 1500. However, the robot can still navigate with its bumper. For best cleaning results, it is recommended that these surfaces be marked as no-go zones on the map.

Reflective surfaces: Reflective surfaces such as chrome-plated table legs or mirrors can be invisible to the robot. However, the Nexaro NR 1500 can still navigate with its bumper. For best cleaning results, we recommend marking the corresponding areas as no-go zones on the map.
Invisible objects: Obstacles that are outside the line of sight of the laser sensor, such as floor-level installations and very thin objects like lamp stands, are not visible to the Nexaro NR 1500. However, the robot can still navigate with its bumper. For best cleaning results, we recommend marking the corresponding areas as no-go zones on the map.

Prohibited areas: The Nexaro NR 1500 is optimized to clean virtually the entire accessible floor area. Define no-go zones to designate areas that the robot should not enter, including passages and doorways (even if a door is usually closed, the robot will go through the doorway if the door is open).

Dark surfaces: Dark, absorbent surfaces such as black furniture or matt objects are more difficult for the robot to recognize and have a negative impact on the robot's ability to navigate. In most cases, the Nexaro NR 1500 can deal with such objects using the bumper. We recommend using the robot in an environment in which the robot has sufficient visible objects for the laser sensor.
Cords: Cords can be wound up by the main brush of the Nexaro NR 1500 or otherwise cause the robot to get stuck. No-go zones can be used to ensure that the device does not run over power cords or other lying or hanging cords or wires. For best cleaning results, we recommend marking the corresponding areas as no-go zones on the map.
Doors: If the robot is to clean several rooms, it is important to establish a process to ensure that the doors between these rooms are opened before the robot starts cleaning. We recommend designating the area around the position of the opened door as a no-go zone. Otherwise, the robot could run into the opened door while cleaning, causing it to close.

Alarm systems: The cleaning schedules of the Nexaro NR 1500 can be coordinated with any alarm systems on-site. To do so, specify the desired start times, end times, and days of the week. This ensures that the autonomous robot vacuum cleaner will not disturb the alarm system.
Labeling: For easy assignment of the robots to their docking stations, they can be labeled with their respective locations using stickers. The recommended location for stickers is under the dust bin lid.

Magnetic strips: The Nexaro NR 1500 has magnetic sensors. Magnetic strips can be used during the initial mapping to exclude areas whose inclusion could cause the mapping to be aborted, such as drop-offs, steps, or complex obstacles (groups of chairs, cords, etc.). These areas can be marked as no-go zones after the initial mapping and the magnetic strips then removed again.


Small no-go zones that make a big difference. How to help the Nexaro NR 1500 do its job effectively.

Problem: Employees could place a device on the docking station facing in the wrong direction, preventing the device from charging.
Solution: Train staff.

Problem: The device could get stuck or detect a fall risk when maneuvering over parts of chairs or other furniture.
Solution: Place furniture in question on tables, remove it, or add no-go zones.

Problem: Drop-off detection when floor outlet boxes are open.
Solution: Ensure that outlet box covers are closed (workplace safety) and add no-go zones if necessary.

Problem: The robot could get stuck on the protruding baseboard.
Solution: Add no-go zones.

Problem: The robot could get stuck under furniture.
Solution: Add no-go zones.

Problem: The device could get caught on cords.
Solution: Add no-go zones.

Problem: The main brush of the appliance could get caught if it passes over curtains or other exposed fabrics during cleaning.
Solution: Add no-go zones.

Problem: During cleaning, the appliance can drive into a narrow area which it cannot leave on its own.
Solution: Add no-go zones.


What should I do if the robot displays a Safe State message in the Nexaro HUB?

Due to its commercial approval, the NR 1500 has mechanisms for detecting safety-critical situations. The corresponding messages in the Nexaro HUB are divided into the following three categories:

Safe State 1

In Safe State 1, the robot independently checks whether a safety-critical situation exists. If this is not the case, the Safe State 1 message is reset immediately and the robot continues its task. If a safety-critical situation is detected, a Safe State 2 message is generated.

Safe State 2

In Safe State 2, the user must confirm that the safety-critical situation has been rectified by pressing the start/stop button.
Example: If a fall edge is detected during cleaning, the robot in the Nexaro HUB displays a Safe State 2.
Solution: The user can move the robot away from the falling edge, secure the falling edge with magnetic strips, for example, and allow the robot to continue moving by pressing a button.

Safe State 3

In Safe State 3, the user must return the robot to the charging station. If a new cleaning process is started, the robot automatically checks its functionality and Safe State 3 is reset if the check is successful.
