It self-empties into a 5 L dock bag, runs for a rated 285 minutes against 120, carries three years of warranty against one and adds Home Assistant to the Alexa and Google Home both support. The iRobot Roomba 105 Combo is the cheaper of the pair and keeps the essentials, LiDAR mapping, no-go zones and a mop pad that accepts cleaning solution, but it has no self-emptying dock. Neither washes, dries or lifts its mop: both trail a simple pad, so mopping is a light wipe on either. Choose the Dreame D20 Pro Plus for low-maintenance vacuuming and long runs, and the iRobot Roomba 105 Combo if the lowest price wins.

What the differences mean

Self-emptying

The Dreame D20 Pro Plus empties into a 5 L bag at its base, rated for months between changes. The iRobot Roomba 105 Combo has no self-emptying dock, so its bin is emptied by hand after runs.

Battery life

The Dreame D20 Pro Plus is rated for 285 minutes, more than twice the Roomba's 120. In a small apartment either finishes; across a larger home only the Dreame is likely to do it in one run.

Warranty

Three years on the Dreame D20 Pro Plus against one on the iRobot Roomba 105 Combo. Given the charging and reliability complaints owners of both mention, the longer cover counts.

Mopping

Both trail a simple pad with no washing, drying or lifting. The iRobot Roomba 105 Combo accepts cleaning solution, the Dreame D20 Pro Plus does not; neither replaces a real mop.

Home Assistant

The Dreame D20 Pro Plus works with Home Assistant; the iRobot Roomba 105 Combo does not. Neither supports Apple Home, SmartThings or Matter.

What owners say

Owners of both robots praise the LiDAR mapping and everyday pet-hair pickup, and both groups call them quiet. Dreame D20 Pro Plus owners single out correct room detection on the first run across carpet and tile, overnight bedroom runs, and even a self-storage operator running four on rough concrete; their complaints are uneven suction and carpet results, hair in the brush, debris clumping on the pad, charging failures and dust bags that jam in the base. iRobot Roomba 105 Combo owners like the methodical room-by-room pattern and simple scheduling, but describe a first map that took several runs or manual edits, a combo mode that avoids rugs, and reliability problems months after purchase.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
