How we do it

Infrastructure agnostic installation

  • Trombia Free requires no sensor installations, lane paintings or other markings around your area.
  • Commissioning process starts when the delivery arrives at your site and we are sweeping literally in minutes.

Environment mapping

  • To begin the commissioning, Trombia Free Commissioning Engineers record and validate the map of your district.
  • After mapping validation, the environment is validated and handed over to your operators for daily sweeping use.

Route planning and teaching

  • The key part of the training program is where your operators learn to design sweeping routes using the radio controller provided together with the sweeper delivery.
  • The Trombia Free sweepers are then scheduled to deliver tasks routinely at the time slots most suitable for your site. For ad-hoc duties you’ll send the sweeper to a mission with a few clicks using the Trombia Free Smooth
    cloud control platform.

Remote monitoring

  • The sweeper can be monitored over the internet connected 360 degrees camera view and assisted using the Trombia Free Smooth control system.

Autonomous dumping and washing

  • The sweeper empties using the autonomous Trombia Free Service Station. At selected intervals the sweeper hopper and dust separating cyclone wash are also performed automatically.

Helpdesk services

  • Trombia’s decades long experience with sweeping products gives us the understanding of type of support our customers when sweeping equipment are out on duty.
  • With Trombia Free Helpdesk plan our service team is monitoring alerts and diagnostics of your sweeper continuously and can give predictive maintenance orders or recommend improved performance based on the system analytics.
