What Is Window Vac
Window vacs are battery-powered suction devices that remove dirty water after spraying windows, preventing streaks common with traditional methods. They feature a wide rubber blade (170-350mm) attached to a vacuum head, collecting liquid in a 100-200ml tank. Kärcher pioneered the category with the WV1 in 2007, now evolved into lines like WV5 and WV6 with LED lights and multi-surface heads. Lightweight at 0.6-1kg, they run 20-100 minutes per charge, ideal for 50-200m² cleaning sessions.
Unlike dust vacuums, window vacs excel at wet pickup only, pairing with spray bottles and microfibre cloths for full cleaning. Popular in damp-prone areas like UK bathrooms or Indian monsoons, they save 30-40% time over squeegees. Tanks empty via quick-release valves, and blades swap every 6 months for ₹500.
Key Components Explained
The suction nozzle (narrow/wide options) glides smoothly; narrow for edges, wide for large panes. Spray bottle attachments hold 300ml cleaner mix (1:500 ratio). Battery indicators prevent mid-job shutdowns. Premium models add scrapers for bird droppings.
Accessories like extension poles (₹1,000) reach conservatory glass 3m high. Tanks rinse in 10 seconds; microfibre cloths washable 300 times.
History and Invention
Kärcher invented the window vac in Germany around 2005, launching the WV1 globally in 2007 as a solution to squeegee mess. Responding to consumer complaints about streaks, engineers developed high-suction motors (7-28kPa) for flawless dry finishes. By 2010, sales hit millions in Europe, expanding to India via Flipkart/Amazon by 2015.
Evolution added lithium-ion batteries in 2012 (WV2), doubling runtime to 35 minutes. 2020s brought smart features like app timers in WV6 Plus. Competitors like Bosch GlassVac (2014) and Tower (2018) followed, but Kärcher holds 60% market share.
