About us

Through delivering hull cleaning machines aimed at the leisure boat market, we help marinas and yacht clubs better serve their customers and members. Hull cleaning with brushes is a smarter, quicker and an environmentally friendly way to keep your boat free from fouling.

The founders
With experience in the field since 2004, the founders established Rentunder AB in 2009 with the intention of producing and selling mobile hull cleaning machines. We soon realized there was a need for machine that could also clean larger motorboats and sailboats, and the result was the BigWash machine.

Today
Today we have customers in 10+ countries in three different continents. Outside of Sweden we work with skilled agents who represents our brand and products.
