My house has 35+ window panes. I no longer need to carry a bucket of dirty water (and having to change out the water all the times) with a bottle of Windex and several towels (for pre-cleaning, with Windex, and drying) around the house and inside. Our window cleaning that used to take us more than 2 hrs was done in less than an hour upon using WV1 Plus the first time. It was so easy to use and I only needed to refill once. It's a joy to clean windows now!
I bought this vacuum two weeks ago and started using it right away. It took me only 1 and 1/2 hour to wash all my 16 windows in the house and they all are spotless now. It’s great product!
While it still takes some time, and effort, this device eliminates the worst part of cleaning windows… Trying to remove all the smudges, streaks, and little bits of paper towel from your freshly washed windows. My windows have never looked so nice. Tip: have a dry paper towel with you so that after you’re finished using this on a window, you can clear up any small remaining smudged areas.
Bought this to replace an old one that lived outside our glass shower, and did double duty for home windows. Not sure what happened, but the old one started making strange sounds when charging, then quit completely.
The new WV 1 Plus works great, is quieter, and seems to have an improved battery. It is smaller, so you'll need to make more passes. Also, I'm not a fan of the liquid tank, it must be completely removed and then the top taken off to empty.
