Trombia Free is the world’s first full power, electric and autonomous street sweeper. Trombia Free delivers up to 10 times faster area cleaning, but uses only 15% of the energy required for advanced high performance sweeping. Hence, the electric era is here.
Our mission is to electrify and automate street cleaning in modern cities and industrial destinations in the most sustainable way possible.
Trombia Free is designed to perform in finest PM2.5 dust removal and heavy mechanical debris sweeping.
At the same time, the average power used in cleaning work varies between 6 kw - 16 kw. With the global-wide patented Trombia sweeping technology this power input is sufficient to deliver the cleaning performance of the heavy duty street scrubbers that are commonly equipped with over 100 kw suction engine power.
Unlike other electric sweepers in the market, Trombia Free has made no compromises with the performance to save battery life.
If you look at electric compact street sweepers and their diesel-powered equivalents, you'll find that suction and sweeping engine power has been decreased down by 90% when the sweeper has been electrified. This has the same impact on actual performance.
Trombia Free can deliver autonomously 5 000 - 7 000 m2 of power-cleaned area surface every hour.
Trombia Free uses in regular urban area sweeping only 6 kwH of energy per sweeping hour. This makes Trombia Free a unique electric heavy duty vehicle across all industries.
Trombia Free is equipped with either Lithium-Ion Battery Packs of 45,6 kwh (Single Pack) or 91,2 kwh (Double Pack). These battery packs will give you 8,5 - 17 hours of non-stop regular urban area sweeping (EN15429-2) or 4 - 8 hours of non-stop high power street scrubbing.
When you consider the area coverage that you achieve with 4-8 hours of non-stop high power Trombia sweeping - the energy efficiency is fully underlined. Trombia Free uses only approximately 1.0 - 2,2 kWh of energy in 1000 m2.
Modern high power street cleaning fleets include several heavy equipment vehicles operating slowly along the streets. The diesel-fuel consumption is over 20 l / hour per vehicle.
In particular the slow-moving suction sweeper, with over 60 - 100 kW suction engine, and only marginal cleaning efficiency, is a heavy consumer for diesel fuel.
This results in dramatic amount of CO2 emissions, and the only way to combat the over 3 million CO2 kg tons that street sweepers around the world cause, is to change to a greener and more power-efficient option. Trombia Free is the solution.
Trombia Free's base technology Trombia, has been certified in the European EUnited PM2.5 Test to the highest 4-star category. In the Trombia's self-initiated dust removal tests in 2017 the same technology was found to remove over 96% of fine PM2.5 dust particles off the street surface.
Trombia Free also saves water over 95% compared to existing suction sweeper technologies. Enough said.
Trombia Free's autonomous machine vision is based on a lidar-based point cloud system. Our advanced algorithm and localisation capability allows us to operate accurately indoors, outdoors, darkness and light, rain, snow and sunshine.
You will get your job done regardless of the weather.
Street sweeping vehicles cost hefty 6-figure investments. Thus, we don't want to give customers any excuses to purchase diesel-fueled sweepers anymore.
To change the world overnight from diesel-fueled alternatives to Trombia Free, we will also enable customers significant cost savings and alternative purchase models to follow the ideals of sharing economy.
Trombia Free is designed for the modern life in smart cities.
Your sweepers operate nightshifts and they have to be significantly quieter than existing high power street scrubbers. In city application we have measured peak noise levels at 76db while from standard distance Trombia Free's noise level has been measured below 70 db.
Trombia Free operations platform is equipped to monitor and observe the functionality and cleaning performance of your Trombia Free fleet.
After the day's duty you are able to invoice the cleaned square meters with one click from your customers, and every invoice includes automatically the amount of CO2 emissions saved by doing the work with Trombia Free - instead of the bad and loud diesel sweepers.
During 2021 we seek to include in the operations platform also a marketplace model, where your clients can publish new cleaning projects for you to bid in. One-click bid, client agrees, and off you go giving the command for your Trombia Free. This feature will increase utilization of your fleet dramatically.
Trombia Free's command and operations system is developed in-house by Trombia Technologies.
This means that integration and upgrading the Trombia Free units with new data collection features such as air quality measurement, road-AI or digital twin recording is made agile and straight-forward through the interfaces.
Integration to smart cities also requires logistics integration to existing waste systems.
