Question about Bissell SpotClean Pet Pro Plus Portable Spot Cleaner

Good day I have been comparing the different models of Bissell Spot Clean. I got stuck with the Pet Pro Plus. Now I'm surprised that the "container" for the water tank is given as 0.8 litres in the specifications, compared with the others: 3.5 litres. Could this be the case or did they make a mistake when typing in the information?
