We've recently been looking for an automatic pool cleaner and one of our friends recommended the Aquabot. I had never heard of the manufacturer, though it turns out they havs been making pool cleaners for over 25 years. Our friend has an original Aquabot and loves it. In fact, it is still going strong 7 years after she bought it. After reviewing the models, I decided to purcahse a newer model called the Aquabot Turbo T. This thing is amazing and fast. It takes about 2 hours tops to clean our vinyl-lined pool and I am always impressed to see how well it handles the steps and sides. It's well worth the investment and we actually got it from aquabots.net where they were extremely helpful in helping me choose a model.
