Conclusion

Window vacs are a great invention and save the hassle of manually cleaning your windows and leaving streaks. Although initially invented by Karcher, many other brands have started to release their own window vacs onto the market.

All of our recommendations are suited to a range of budgets and are able to run for at least 30 minutes. For the best results on tough dirt, we strongly recommend using a high quality glass cleaner beforehand.
