What reviewers found
Dreame D20 Plus
- Vacuum Chef (95/100): Hands on review of a unit supplied by Dreame: strong cleaning on carpet, rugs and hard floors and good tangle resistance, but small or low objects were bumped and it reached about 74 dB at max suction. Source
- Vacuum Wars (2.90 Vacuum Wars stars): Removed 93% of embedded sand and 91% of flattened pet hair with 0% long hair wrap, and estimated about 2,761 sq ft per charge. It avoided 0 of 24 obstacles, crevice pickup was below average and mopping scored below average on dried stains. Source
iRobot Roomba 105 Combo + AutoEmpty Dock
- Vacuum Chef: Hands on test with the AutoEmpty dock. Measured 395 FPM airflow on carpet against a 420 FPM category average, the best it has recorded for an entry level iRobot. Mapping was much faster than older non LiDAR Roombas. The mop only drags and does not lift, hair tangles on the roller and the firmware update took nearly an hour. Source
- Tek.no (Norway): Rated it mediocre. Vacuums well and LiDAR improved navigation over older Roombas, but it got stuck, took a long time, has lower suction than rivals and a basic wet cloth mop. Source
