A strong pick for carpet and pet hair for about $310. Vacuum Wars measured 93% embedded sand and 91% pet hair pickup with zero hair wrap, plus a 5 L bag dock and a three year warranty. It avoided none of the test obstacles and the mop is basic, so it suits tidy homes.

A well rounded all in one robot that Vacuum Wars ranked #1 at review time, with top five carpet pickup, perfect pet hair results, strong obstacle avoidance and record threshold climbing. Battery coverage is below average, and a long term tester saw weekly dock clogs with a heavy shedding dog. The 3 year warranty is a real plus at this price.

What reviewers found
Dreame D20 Plus
- 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
- 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
Dreame L50 Ultra
- Vacuum Wars (3.84/5): Measured 90% carpet sand removal, 100% pet hair pickup, 20 of 24 obstacles avoided, a 211 point mopping score versus a 188 average with 0.35 g of water left, and a 42 mm threshold climb; coverage was below average at about 823 sq ft per charge. Source
- Vacuum Wars (3 month test): After three months of daily use with kids and a heavy shedding dog, mapping and obstacle avoidance held up, but hair formed clumps, the dock and bin clogged about once a week, and the app did not warn of clogs. Source
- RTINGS: In RTINGS' comparison with the L40 Ultra, the L50 Ultra handled pet hair better and had stronger obstacle avoidance and threshold clearance, while the L40 Ultra cleaned hard floors and carpet better. We could not read RTINGS' numeric scores. Source
