    Fabulous home window cleaning helper

    We bought the Ecovac window cleaner as we have a large number of large floor to ceiling windows leading onto our deck. It has been fabulous. Saves time as you can do other things whilst it is working, was easy to use, and left our windows spotless. We bought some extra pads and cleaning solution so that we could change the pads frequently to ensure no smearing. It was slow, but thorough, as we did the hard clean initially which takes longer. Even the edges were done beautifully. The only downside is that we have a few horizontal narrow windows which it did not work on as there was insufficient space for the unit to turn and do its job. But it worked really well on the rest.

    It really works

    I have recently purchased this product and am currently giving it a thorough workout. I am really impressed. Our windows are primarily old wooden double-hung with locking latches. The Winbot navigated these latches (I expected it to get stuck on them) and was able to clean the windows without getting confused about these obstructions. The windows were quite dirty, given the manual effort to clean them. The Winbot made short work of them, getting them very clean (but understandably not perfectly clean) the first time it was used. I expect with regular use from now on, the windows will remain much cleaner. I have also tried it on a frameless shower screen, glass pool fencing and glass balustrading. It handled tham all very well. The technology is quite amazing, and the whole package is cleverly housed in a portable case. It can run on battery alone or be connected to power. I feel it wise to use the manufacturers cleaning solution. Their cleaner has been noted as relatively expensive, but that pales into insignificance compared with the cost of a professional window cleaner, or the amount of valuable time and effort you will save over having to clean the windows yourself. If I could give this product more stars, I would

    More streaks than a Collingwood football match

    I have tried all the advice and nothing works - I wanted this to work but sadly it just leaves the windows covered in smudges and streaks

    Window cleaning - Easy to use - must have for cleaning your windows

    I was extremely impressed with my new Ecovac Winbot W2. I had been recommended by a friend, so I had to try. My windows were filthy, a job I hate, an easy way to clean your windows. Attach and let it do its thing, when it's finished will let you know, remove and start on the next window. It Even tells you when you need extra cleaning solution and when to clean the pads. I would defiantly recommend and have too others. I love this new product.

    A fantastic gadget

    Clean windows easily achievable at any time, with minimum effort. Can’t recommend it highly enough. And, as ever, my associated dealings with The Good Guys went without a hitch,.
