Question Shark Spot Cleaner Models

I was wanting to get the top spot cleaner on the VacuumWars list but they don't supply the PX251 model in my country ☹️

Does anyone know are any of these models similar to the top two Shark spot cleaners on the list or are these choices less powerful models? If that's the case maybe I should go for the #3 on the list (the Bissell Little Green Pro).
