10 Best Window Vacuum Cleaners 2025 in the UK

The Kärcher WV 1 Window Vac bundle, including an extension set, is designed to provide a streak-free clean for windows and other smooth surfaces like mirrors and tiles. With a battery life of 20 minutes, it is well-suited for quick cleaning tasks, and the LED display helps you track the remaining charge. Weighing just 0.5 kg, this device is lightweight and easy to handle, making it comfortable for prolonged use without causing fatigue.

Its suction power effectively absorbs moisture, preventing streaks and leaving surfaces clean. The 100 ml water tank, although small, is removable for easy emptying of the collected dirty water. Its quiet operation is a plus, allowing you to clean without causing much disturbance.

The included extension set is a practical addition for reaching high windows, as it features two telescopic rods with a flexible joint and a wiper with a microfibre cloth. This feature is particularly beneficial for cleaning areas that are otherwise hard to reach.

On the downside, the 20-minute battery life may feel limited for larger cleaning tasks, requiring frequent recharges. The water tank's capacity might necessitate regular emptying during extensive cleaning sessions. Some users may find these factors inconvenient if they have numerous windows or large glass surfaces to clean.

This Kärcher bundle is ideal for those looking for a lightweight and efficient tool for small-scale cleaning tasks and harder-to-reach areas. Its ease of use, compact design, and efficient cleaning performance make it a strong contender in the window vacuum category, particularly for everyday household use.

The Kärcher Window Vac WV 5 Anniversary Edition is a well-rounded window vacuum cleaner designed to make window cleaning easier and streak-free. Its rechargeable lithium-ion battery offers up to 35 minutes of cleaning time, which is enough to cover about 75 windows or 105 square meters in one go—great for regular household windows or small commercial spaces. The device includes two suction nozzles (170mm and 280mm), allowing you to clean both small and larger window panes efficiently. The unique adjustable edge guidance helps to clean right up to silicone seals without leaving streaks, a feature that many users will appreciate for precision cleaning.

Weighing just 1.19 kg, the vacuum feels light and manageable, making it comfortable to hold for extended periods. Kärcher products generally operate quietly, so it shouldn't disturb your home environment much. The WV 5 comes with practical accessories like a spray bottle, two microfiber cloths, a dirt scraper for stubborn grime, and a small bottle of cleaning concentrate. These extras add convenience since you have most of what you need right out of the box. One handy feature is the three-stage LED battery indicator, which shows how much charge is left and helps avoid surprises during cleaning.

If you need to clean very large windows or extended outdoor areas frequently, the 35-minute battery life might require some recharging breaks. While the vacuum is great for windows, it may not be the best tool for other glass surfaces like mirrors or tiles if heavy-duty scrubbing is needed. The Kärcher WV 5 Anniversary Edition suits homeowners looking for an easy-to-use, lightweight, and effective window vac with good battery life and useful accessories to achieve streak-free results quickly and comfortably.

Weighing only 1.11 kg, it is lightweight and ergonomically designed, making it easy to maneuver and reducing hand fatigue during prolonged use. The inclusion of two suction nozzles, one for large surfaces and another for narrow areas, adds versatility to its functionality, allowing you to clean different types of windows effectively.

Additionally, the set comes with a spray bottle, microfibre cloth, and window cleaner concentrate, providing everything you need for a thorough clean right out of the box. Users appreciate its quiet operation, which makes it less intrusive, and the hygienic feature of an easy-to-empty dirty water tank.
