As the connector assembly between your EvaClean Protexus Electrostatic Backpack and Spray Handle, the larger hose connects the larger water line to the sprayer, and the smaller electric line to the base of the sprayer. Our sprayer handle features an easy-to-use quick-release coupler and spring-loaded tab for your safety and convenience. Identical to VRP32, compatible with VP300ES. EASY MAINTENANCE: To reduce the chance of blockage in the sprayer's hose and nozzles, simply allow a tank of clean warm water to travel through the unit to rinse out any residual chemical build up after every few days of use: it is recommended that users purchase a second tank to wash out cordless electric static sprayers. ONE YEAR WARRANTY: If there's a problem or failure beyond regular wear and tear or tool abuse, we'll make it right. EvaClean will repair or replace, without charge, any defects due to faulty materials or workmanship for one year from the date of purchase. WHY PROTEXUS?: Cordless electrostatic spraying technology brings new 360-degree touchless cleaning capabilities to cleaning teams across all industries. The electrostatic charge of the sprayer allows the droplets to attract to the surface rather than float in the air, as is typically associated with a mister or fogger, nearly eliminating safety concerns for acute or long term worker exposure by comparison. NEXT GENERATION SOLUTIONS: Gone are the long cleaning schedules, harsh chemicals, and bulky products. With the most powerful and reliable charge available, the EvaClean Protexus Handheld Electrostatic Sprayer is a way to build a safer, healthier world at a lower cost. At the end of the day, we're not working just to keep spaces clean - we're working to protect and save lives. All EvaClean Protexus accessories are compatible with the Victory Innovations line of electrostatic sprayers.
