The kirby shampoo system is somewhat a joke and also a gemic. Yes it shampoos and refreshens your carpets, but it doesn't extract and removes the stains. Not only that but it's wide and bulky,loud and unbareable, especially when you use it to mop the floors assuming you have the new updated multi surface shampooer that came out with the avalir back in 2014. Which for that you'd still would need a mop to get into the hard to reach places that the multi surface shampooer can't reach. And this is coming from somewhat who grew up with a kirby system in the home.
As an adult who owns a rainbow system, I like the aquamate a lot better than a kirby shampooer. I like how streamline the system is, meaning I could get into hard to reach areas, whereas with a kirby I couldn't. The other main thing i like with this system is that it extracts the stains. Now my only critic with this system is that the soap solution sides need to be bigger. In fact both the water side and solution sides could be increase to a bigger size. I would love to see how rexair will improve this accessory in the future.
But for the time being kirby needs to come up with something new. The g-series, more specifically the avalir systems need to be replaced with a new model. The same with its shampoo systems.
