[Case Study] Hard Court at a Certain Tennis School in Kanto

All hard courts (6 surfaces) in the school were cleaned over 6 days! A case where the original color became visible.

A certain tennis school management company was troubled by moss adhering to the accumulated dirt on the hard courts (concrete painted floors) within the school. When it rained, the surface became slippery due to the moss, posing a risk of students slipping and falling. In response, our company used the 'HOTJEBLO Fujiyama R2' to clean all six hard courts over a period of six days. The original colors painted in red and green became visible again, and the management company was very pleased. Additionally, the risk of injury was reduced, and we received high praise from the students of the school. 【Case Summary】 ■ Equipment Used: HOTJEBLO Fujiyama R2 ■ Issues - Moss adhered to the accumulated dirt on the hard courts (concrete painted floors) within the school. - When it rained, the surface became slippery due to the moss, posing a risk of students slipping and falling. ■ Results - The original colors painted in red and green became visible again, which was greatly appreciated. - The risk of injury was reduced, and we received high praise from the students of the school. *For more details, please refer to the PDF document or feel free to contact us.

Overwhelming reduction in work time! By eliminating wastewater discharge and enabling simultaneous cleaning and wastewater collection, it is possible to centralize the process.

We have verified how the "Hot Jeblo Method" is superior to conventional high-pressure washing. Conventional high-pressure washing requires protective measures against splatter and post-treatment of wastewater, but with the "Hot Jeblo Method," there is no wastewater runoff, allowing for the integration of washing and simultaneous wastewater collection. The advantage of simultaneous washing and wastewater collection is a significant reduction in work time. We have a verification video, so please take a look. 【What is the HOTJEBLO Cleaning System?】 ■ HOT (hot water device) + JET (high-pressure pump) + BLOWER (vacuum) ■ Integration of high-pressure washer, hot water device, and vacuum ■ Simultaneous processing of washing, rinsing, and wastewater treatment in three steps ■ Significant reduction in work time and labor *For more details, please refer to the PDF document or feel free to contact us.
