Roborock E20 is measured by 13.8 x 13.9 x 3.6 inches, featuring a generous dust bin (about 640 mL) and high wheels to transverse from bare floors to high pile carpets easier.

The Roborock E20 uses an 1800 Pa motor to generate suction. This motor power is 3 times more than the Roomba 600s series (Roomba 614, Roomba 650, and Roomba 690 use 600 Pa motor). Comparing with Ecovacs Deebot or Eufy Robovac, this motor power is also stronger than these direct competitors.

For example,

  • Deebot N79S (the most popular robot vacuum choice at a low price) uses 1000 Pa motor
  • Eufy Robovac 11S uses 1300 Pa motor

 This implies Roborock E20 can deliver more suction power than most of the entry-level robot vacuum on the market.
