If you hate vacuum maintenance, the Roborock S8 MaxV Ultra wins this one handily. Its dock does almost everything for you.

What You Never Have to Touch

The RockDock Ultra handles:

• Emptying the dustbin
• Washing the mop pads with hot water
• Drying them so they don't get gross
• Refilling the water tank
• Adding cleaning solution
• Even cleaning its own base tray

For an extra $100, you can get the plumbed version. Then you literally never touch water tanks.

The Roomba j9+ dock empties the dustbin. That's it. (To be fair, the j9+ doesn't mop, so there's no mop maintenance anyway.)

Stuff You Still Have to Do

Both vacuums need occasional attention:

• Swap out dustbin bags monthly
• Clean sensors when dusty
• Replace filters every few months
• Check brush rollers for tangles
• Replace worn brushes eventually

These aren't big tasks, and they're similar for both.

The Fine Print on "Self-Cleaning"

The S8 MaxV Ultra's dock needs occasional deep cleaning. The dirty water path can start to smell if you don't wipe it down every few weeks. "Self-cleaning" doesn't mean "never needs cleaning."

The Roomba's simpler dock doesn't have this issue. Less stuff to go wrong.

Which Approach Works Better?

If you want minimum effort: The S8 MaxV Ultra. Deal with maintenance monthly instead of after every cycle.

If you hate complicated things: The Roomba j9+. More manual tasks, but simpler system. Nothing fancy to break.

The tradeoff is automation versus simplicity. The Roborock does more for you, but it's more complex. The Roomba does less automatically, but there's less that can go wrong.
