Frequently Asked Questions

Can you charge the machine at a Tesla charger?
No not currently.  We have a 6.6 kWh charge port; the Tesla charge stations use 150 kWh to 200 kWh charging, so your unit has to have the proper infrastructure and safety features to handle all that power and heat.

How did you test the run time on the blower?
For the blower we used free air meaning we were not sucking up any material.  All soil conditions are different so to get a true test Free Air was the only viable solution.  Much like testing a water or mud pump; pumps are rated using fresh water at sea level, any variation impacts how much the pump can pump.  We are similar.

So how much run time can you get out of the vacuum/blower?
It depends on the CFM.  Our blower runs at a constant 20 Inches of Mercury regardless of CFM.  At 540 CFM using free air it will run about 7 hours.  At 1,000 CFM it will run at 1 and ½ hours.  It is 4 times more efficient at 540 CFM vs 1,000 CFM.

How did you test the run time on the water pump?
We used fresh water and ran it at our shop at 3,000 PSI at 3.5 GPM.  With only running the water pump at this level it will go 7 hours.

How long will it run on my job?
That depends.  Many variables come into play.  We have done everything possible to increase the run time on an actual job.  Our goal was to operate the machine without recharging on a typical 8-hour work day.

How long will the battery last?
We have based our battery on working 40 weeks a year, 5 days a week.  Our battery is 2,000 Duty Cycles.  Based on this it would last 10 years.  After 2,000 Duty Cycles the average run time will drop about 20%.  It would still have the same power, the run time would just be reduced.

When I push the turbo button to go to 1,000 CFM it hits 1,000 and drops the CFM back to 540?
You need to open the mud hose valve, it is dead heading and it is self-adjusting itself.  Open the valve and it will maintain 1,000 CFM.

How did you measure the noise level (DBA)?
The International Standard for measuring noise level is the following: You measure at a distance of 7 meters/21 feet from four different points from the source of the noise.  Think of the blower being the center of the noise and you measure North, South, East and West all at a distance of 21 feet/7 meters.

How do you calculate fuel savings?
It costs on average about $3.80 to fully charge our battery an equal amount of diesel would be about $65 at current national fuel average prices.  So, go back to our 40 weeks a year working 5 days a week on average, so we do the following math:

  • 5 days X $3.80 = $19 per week X 40 weeks = $760 per year for electricity
  • 5 days X $65 = $325 per week X 40 weeks = $13,000 per year in diesel.
  • $13,000 – $760 = $12,240 in yearly fuel savings.
