What reviewers found
Roborock S8 MaxV Ultra
- TechRadar: Strong vacuuming and effective mopping on coffee and dried honey, fast accurate mapping. It got stuck on cables repeatedly, tried to vacuum a sock, and the extending side brush and voice assistant were unreliable. Subscores: Value 3.5/5, Design 4.5/5, Performance 4/5. Source
- Vacuum Wars: Measured 0.18 kPa max suction and 13 CFM airflow, 1.41 min per 1% battery and 0.62 m² per min navigation. Handled dried coffee and grape juice stains with minimal streaks, and its feature score was the highest Vacuum Wars had recorded at the time. Source
Roborock Saros 10R
- TechRadar: Noise measured 62 dB at source and 55 dB at 10 feet. Oats were cleared but flour stayed in floor seams on Max and Max+. It cleaned a syrup, soy sauce and milk spill in one pass on low water and mapped five areas in about 5 min. It rode over a 1 inch dog bone until Pet mode was turned on, and the dust bag filled in about three weeks. Source
- 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
