In the busy seaports of the United States, where cleanliness and efficiency are paramount, autonomous street sweepers are undergoing testing to revolutionize the method and efficiency of cleaning city streets, parking lots, warehouses, and garages. The Port Authority of New York and New Jersey has piloted the use of these electric, driverless machines, known as Trombia Free, to enhance and extend cleaning services beyond regular business hours.

Trombia Free is a remarkable autonomous street sweeper developed by the Finnish company, Trombia Technologies. It is a hefty machine, weighing in at 5,000 pounds and having the ability to pick up three to four thousand pounds of both wet and dry debris. Despite its size and weight, the Trombia Free, akin to a substantial robotic vacuum cleaner, employs LiDAR and machine vision technology to navigate and clean city streets and pathways with the ability to avoid obstacles and operate in all weather conditions, day and night. It limits its speed to between 2 and 6 km/h (1.2-3.7 mph) for optimal sweeping and dust removal.

Trombia Free’s design prioritizes eco-friendliness and efficiency, using less than 15 percent of the power needed by current heavy suction sweeping technologies. The power consumption is around 6-10 kW for urban cleaning, significantly less compared to the large diesel street scrubbers that might use between 70-130 kW. This autonomous street cleaner is not just about efficiency and power conservation; it’s also about endurance. Its battery can last between 8.5 and 17 hours per charge for regular urban street cleaning operations or between 4 and 8 hours for continuous high-power sweeping. Customers have the option to choose between 45.6- or 91.2-kWh Li-ion battery models.

The application of Trombia Free in areas like parking garages and industrial lots is expected to significantly grow in the next five years. According to Antti Nikkanen, Trombia Technologies CEO, automation is anticipated to permeate the cleaning industry, starting from these types of locations where an increase in cleaning frequency is necessary due to the accumulation of dust and the need to enhance the cleanliness of different industrial sites.

One of the major advantages of deploying Trombia Free, as highlighted by Ignacio McBeatch from the Port Authority of NY & NJ, is the economic savings it will bring. Extending the service into evenings and weekends provides more coverage, translating to a more cost-effective solution for maintaining the cleanliness of various sites.

Although the Trombia Free comes with a hefty price tag of $450,000, the long-term benefits, including extended service hours, reduced power consumption, and enhanced cleaning efficiency, make it a promising investment for urban and industrial cleaning.

Trombia Free Autonomous Street Sweeper Top Speed
The Trombia Free, with a top speed of 10 km/h, is limited to 2-6 km/h for optimal, safe, and efficient sweeping and dust removal on city streets.

Currently, Trombia Free autonomous street sweeper is commercially available, and the company has begun system deliveries. The lead time for new client projects is estimated to be 6 to 12 months from order confirmation. Interested parties can place their orders or inquiries through the company’s website to embark on the journey to more efficient, automated, and eco-friendly urban cleaning solutions.
