I have a shark combo that’s a few years old- the vacuum piece definitely clogs more thany old solo robot vacuum. I’m not sure if in recent years it’s gotten better, but having to empty it daily is still better than vacuuming manually. The mop function you have to install the water tank and put the mop pad on to use it and I find it does a fairly good job. Still need to vacuum and mop manually time to time but the in between is helpful.
