## 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](https://www.techradar.com/home/robot-vacuums/roborock-s8-maxv-ultra-robot-vacuum-review)
- 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.

### Roborock Saros 10R

- 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](https://bgr.com/reviews/roborock-saros-10r-review/)
- 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.

- 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](https://vacuumwars.com/roborock-saros-10r-review)
