Wow the vax cylinder one? You mean this one
Going back some years that one, my Grandmother and Mother had them back in the late 80s. However, they still smell it now, so it has definitely stood the test of time.
However, nowadays most carpet washers are almost exclusively the upright ones.
If you have been satisfied by the cyclinder one, you’ll be blown away by the upright ones, as they have an agitating/spinning brush in them, and offer a stronger extraction of water than the older ones .
I have had 3 vax upright and 2 Bissell upright ones over the years, and I have been very satisfied with them all. I have always been able to keep every carrot looking brand new. Even had a cream carpet that must have been 25 years plus old and it still looked brand new when I downsized a few years back.
I currently have the 4th one down on this page. I really like it.
Have a look at all the models on that page.
