The GVS Backpack Sprayer is a portable battery powered sprayer designed for professional window cleaning and soft washing. With a 16 litre tank, lightweight build and adjustable shoulder straps, it is made for longer jobs where comfort and easy movement matter. It is a practical choice for applying cleaning solutions across glass, frames, uPVC and exterior surfaces without dragging hoses and heavy equipment around the property.

Powered by an 18–21V lithium-ion battery, the sprayer delivers up to 3.5 hours of working time and recharges in around 4 hours. The dual nozzle design helps increase coverage so you can spray larger areas more quickly and evenly. It can be used with a variety of solutions and solvents, making it a useful tool for both professional cleaning work and general property maintenance.

The GVS Backpack Sprayer is supplied as a complete setup with a lance, adjustable straps, two hoses, a battery and charger. You can choose either a Series 21 Female connection or a Claber® Aquastop connection to suit your preferred setup. The current spray lance is made from stainless steel and brass for strength and pressure resistance, but for long term use with hypochlorite it is worth noting that this type of chemical will gradually corrode brass and affect stainless steel over time. Occasional use will not cause rapid corrosion.

After each use, rinse the tank with clean water and flush the pump and hose thoroughly for 3 to 5 minutes before storage. This helps prevent spray materials from hardening and blocking the nozzles, hose and shut off valve. The sprayer should not be used with strong acids, strong bases, flammable liquids or hot liquids above 29°C, and appropriate protective clothing, gloves, respirator and eye protection should always be worn when working with chemicals.
