Ava mini dishwasher or ava compact dishwasher?

Hi! I'm planning to buy a mini or countertop dishwasher and I've seen this ava mini dishwasher. There's only me and my husband at home but since both of us are working natatambak na minsan yung hugasin so that's why naisip ko na bumili ng dishwasher. And maliit lang gusto ko kasi maliit lang din space namin sa kitchen. But my problem is hard water ang tubig namin and this ava mini dishwasher doesn't have salt compartment. So I'm thinking of buying their compact dishwasher but it has larger footprint and the installation of water is kinda hassle although pwede naman direct from the bucket daw. Aside sa detergent need din ng salt at rinse aid di katulad ng mini dishwasher nila. Is it worth it buying ba? Or i should opt for their compact dishwasher? Sa mga nakabili at gamit na ng either sa 2 dishwasher na ito please help me to decide which one should I buy.
