Ecovacs Deebot X11 OmniCyclone vs Kärcher RCV 3 Robot Vacuum

The Deebot X11 OmniCyclone is the stronger machine: far more suction, a self-washing roller mop, a bagless self-emptying dock and roughly double the runtime. The Kärcher RCV 3 is a simpler, quieter robot that handles hard floors and low-pile carpet and is easy to live with, but it lacks a self-emptying base and its suction is modest. Buy the Ecovacs for deep cleaning, pet hair and hands-off maintenance; buy the Kärcher if you want a quiet, basic mop-and-vac with app no-go zones and don't need a dock that empties itself.

• Choose the Deebot X11 OmniCyclone if you have pets, mix carpet and hard floors, and want a dock that washes the mop and empties the bin without bags.
• Choose the Kärcher RCV 3 if you mainly have hard floors and low-pile carpet, want quiet operation and simple app control, and don't need self-emptying.
