I always wondered how good that trio was. I had their old GLS. It was good. Not great, but good.I bought my 15'' Whittaker Trio off ebay for $1995 in December 2017. So I got it at a good price. I only used it 2 times. It does a good job and it is truly low moisture cleaning. It has a fine mist and the carpet is dry in 15-30 minutes. I have the extra stiff blue brushes and standard grey brushes.
