Testimonials

I have worked with Rozone for many years. They provide an effective solution which supports the operation of our business. In addition, Rozone supports some of the more technically challenging situations we are faced with by giving direct industry support as well as chemical and microbiological support. This can result in large savings for our insurance customers. For example, with the expert advice we receive from Rozone, we are able to support the insurance companies with invalid claims. On one job alone we were able to save the insurance companies significant funds by using the expert microbiological advice from Rozone.

The support from Rozone has been fantastic, any problems have been resolved next day, we are always able to speak to somebody. The ROwasher machine itself is brilliant for what it needs to do. It’s a necessity to have this machine when doing engine repairs. The environmental benefit is a welcomed added bonus.

Dick Lovett Mini, Swindon

The new ROwasher has a much better cleaning capability than the previous parts washer. The eco-mode makes the machine cheaper to run. The job is made far easier having the machine opposed to using rags. Our workshop would be lost without it.

How ROwasher Works

Increase service revenues, generate profit and shorten turnaround time while delivering a first-class clean that traditional cleaning methods cannot match. The ROwasher offers innovative superior cleaning power that is safe and effective on any part of the bike – cleaning easily without dismantling.

Simply wheel the ROwasher sink to the bike stand and clean. The flo-thru brush and flexible nozzle allow you to reach every nook and cranny. The ROwasher cleaning solution, ROwash Bike tackles the removal of dirt and grime from bike parts, quickly and efficiently, with no hazard to users or the environment.

Any Questions?

Is the ROwasher Static more energy efficient than traditional solvent washers?

The ROwasher is designed for maximum energy efficiency. It features a double-skinned, insulated MDPE tank that retains heat better than single-walled alternatives. Additionally, it includes a built-in "Eco-Mode" that automatically lowers the temperature from its active 42°C to 37°C after four hours of inactivity. Laboratory trials show that the ROwasher uses approximately 54% less energy than leading competitor machines, helping businesses lower their carbon footprint and electricity bills.

What kind of maintenance is required for the ROwasher?

The ROwasher Static is designed for easy, in-house maintenance without the need for expensive external service contracts. Maintenance typically involves two simple steps:

  1. Monthly Filter Change: Replace the Microbial Filter Mat every month to replenish the colony of oil-eating microbes.
  2. Fluid Top-up: Add 20L of ROwash Degreasing Solution when the machine’s "low fluid" indicator light activates.

The machine also features a 200-micron basket filter in the sink tray to trap large debris, which can be easily emptied by the operator.

Can the ROwasher Static be used for cleaning bikes and sensitive metals?

Yes, the ROwasher Static is highly versatile and compatible with various specialised cleaning solutions. Depending on your needs, you can choose from ROwash 03 (General Degreasing), ROwash 06 (Specialist Metals/Aerospace), or Bike Wash. Because the system is pH-neutral and solvent-free, it is safe for sensitive components and materials that might be damaged by harsh chemicals, making it a favourite for professional cycle retailers and high-precision engineering workshops.

What are the safety benefits of a solvent-free parts washer?

The ROwasher eliminates the hazards associated with traditional solvent-based cleaners. It uses a non-flammable, non-toxic, and VOC-free (Volatile Organic Compound) aqueous solution, which removes the risk of harmful vapours and skin irritation. By switching to a solvent-free system, businesses can simplify their CoSHH reporting, improve workplace health and safety, and ensure compliance with environmental legislation such as ISO 14001.

How does ROwash help with CoSHH and ISO 14001 compliance?

Switching to ROwash simplifies environmental and safety compliance. Because the solutions are solvent-free and biodegradable, they significantly reduce hazardous waste generation and simplify CoSHH (Control of Substances Hazardous to Health) reporting. Using a bioremediating system like ROwasher helps businesses meet sustainability targets and comply with environmental legislation such as ISO 14001 by eliminating the need for frequent hazardous waste collections.
