No I would not recommend it as a replacement

Roborock E4 vs E5 I believe the mop pad is an excellent addition. The mop pad has its place, but it cannot replace the traditional method of scrubbing the floor on your hands and knees. The roborock s50 was designed primarily as a vacuum cleaner and operates admirably in that role; the "mop" is really a well-mounted bathroom washcloth that is automatically dampened by the water tank. I tested it on an uninterrupted tile floor (kitchen, hallway, dining room, mudroom) and it performed as expected. Consider mopping the floor with a damp cloth and doing a single wipe by hand. That is the function. No, I would not recommend it as a replacement for a full cleaning of my tile floors. However, the mop would be used for maintenance surface cleaning in between scrubs. If you're considering this product, the idea of sweeping, cleaning, or mopping undoubtedly doesn't excite you ( just like me). You could waste an hour of your day cleaning and sweeping, or you could kick back on the couch and let the vacuum do the job. It's mop pad probably works better as a dust mop on well-sealed hardwood floors, but I don't have any hardwood floors so I can't confirm this. Overall, the mop adds versatility to the roborock s50, but it will not convince you to abandon your mops and scrub brushes for comprehensive cleaning. I hope this does not prevent you from choosing a roborock s50 vacuum. My machine has been in my possession for two weeks, and I can confirm that it was meant primarily as a vacuum/sweeper. It performs an excellent job of collecting lint, dust, cat hair, cotton wood tree fuzzys, sand, and other detritus. I hope this answers your question.
It works far better than I expected. The vacuum rotates and moves in both directions in order to brush over the walls and furniture. As I did with my previous robot vacuum, I plan to use my regular vacuum cleaner once a month to do edging around obstacles. Please be aware that it will recognise carpets, but owing to the manual placement of the water tank, it will not prevent mopping on the carpet. If you do not want your carpets to be mopped, you may divide your space into zones with carpets, or you can use magnetic strips to correctly insulate your carpets to prevent mopping.
