The Dreame X50 Ultra’s spinning, auto-lifting mop pads significantly outperform the Qrevo 798’s simpler wiping system. If mopping is your priority, the X50 Ultra is noticeably superior; for occasional mopping, the 798 does a respectable job.Does the extra $600-700 price difference justify buying the Dreame X50 Ultra?

It depends on your needs. The X50 Ultra excels at thick carpets, corner cleaning with its extendable brush, and active mopping. If you have hardwood floors, minimal pets, and don’t need advanced mopping, the Roborock 798 offers excellent value at roughly half the price.Do both robots have self-emptying bases
