What reviewers found
Roborock Saros 10R
- Vacuum Wars (3.64 Vacuum Wars stars): Picked up 80% of embedded sand from medium pile carpet against a 75% average and 92% of flattened pet hair, with 0% hair tangling. Avoided 24 of 24 obstacles. Cleared 20 mm and 26 mm boards but failed a single 36 mm threshold. Estimated about 1,389 sq ft per charge. The onboard bin is 270 ml. Source
- BGR: Called it Roborock's best model at launch. It fit under sofas and beds, had about 57% battery left after about 80 minutes of vacuuming and mopping, and needed tank service every four to six cleanings. It tangled in cables until a no go zone was set. Source
Roborock Saros 20 Sonic
- Vacuum Wars (3.81 Vacuum Wars stars): 92% carpet deep clean (78% average), 0% hair wrap, 78% pet hair pickup (82% average), 19 of 24 obstacles avoided, 57 mm threshold climb, about 1,225 sq ft per charge. Dried stain score 62 against a 108 average, the main weakness. Source
- PC-WELT: Editors' Choice and named its new number one in the premium segment. Measured about 55 to 58 dB(A) in standard mode, cleaned 70 m² in 103 min on turbo settings, and handled single thresholds of about 5 cm in practice. Less effective than roller mops on dried dirt. Source
