Bumper robot vacuum: a protective shield for the robot and your furniture

Date published

Bumper Saugroboter: Schutzschild für Roboter und Mobiliar

A Bumper (also known as a collision sensor) is a movable component located at the front of or around the body of a robot vacuum cleaner. It acts as a mechanical sensor that detects physical contact with obstacles. As soon as the bumper is pressed in slightly, it sends a signal to the control unit, causing the robot to stop immediately, reverse or change direction.

In professional cleaning, the bumper is the final safety measure that protects both people and equipment from damage.

The function of the bumper on the Nexaro NR 1700

Although the Nexaro NR 1700 primarily navigates contactlessly using LiDAR and ultrasound, the bumper plays a crucial role in operational safety:

  • Mechanical fallback: Should an obstacle (e.g. a very thin chair leg or a reflective object) not be detected in time by the optical sensors, the bumper reacts immediately at the slightest touch.
  • 360° safety: The bumper is designed to detect not only frontal but also lateral contact. This is particularly important when manoeuvring in confined office environments.
  • Gentle contact: High-quality bumpers are spring-mounted and fitted with rubber lips or soft-touch elements to completely prevent scratches on furniture or delicate surfaces.

Why the bumper makes commercial robot vacuum cleaners safe

Unlike consumer devices, commercial robots must meet stricter safety standards. The BumperB contributes significantly to certification in accordance with IEC 63327:

  1. Personal safety: In environments where people are working, the BumperB ensures that the robot stops immediately upon contact with a foot or an obstacle.
  2. Robot durability: It protects the sensitive technology inside the housing from shocks.
  3. Fault-free navigation: The bumper helps the algorithm recognise when an area is physically impassable, thereby supporting the refinement of the digital map in the Nexaro HUB.

Bumper and sensor fusion: precision meets safety

The Bumper robot vacuum never operates in isolation at Nexaro. It is part of a ‘sensor fusion’ system: whilst the LiDAR sensor plans ahead, the Bumper acts as a tactile safety sensor. This combination enables the Nexaro NR 1700 to clean as close as possible to objects without posing a safety risk.

Reliable hardware for professional use

The bumper is the physical guarantee of damage-free operation. With the Nexaro NR 1700, you can rely on a system that protects both your premises and your staff thanks to its robust construction and intelligent sensor technology – day after day, job after job.
