What reviewers found
Roborock Qrevo CurvX
- TechGearLab (85/100): Ranked first of 23 robots. Hard floor and mopping 9.3, carpet 8.4 with about 79% of debris cleaned, but only 52% of pet hair. Avoided 88% of obstacles. Measured 56.3 dB vacuuming. Source
- Vacuum Wars (3.69 Vacuum Wars stars): Long term test in a 750 sq ft home with a dog. Mopping was strong with vacuum then mop runs and nothing wrapped the brush, but the 260 ml bin clogged almost daily and it often tried to climb objects and needed help. Source
Roborock Saros 20 Flow
- House Digest (9/10): Floors came out about 90% clean with some crumbs left in corners. Mopping fully removed ketchup and barbecue sauce and left wood almost dry. It cleared a baby gate but got lost once and had underwhelming edge cleaning. Source
- EFTM (92%): Australian review gave vacuuming 93%, mopping 93%, app 92% and features 93%. It cleaned dried jam and tomato sauce, needed two passes for Vegemite and struggled with crumbs near cabinets. Charging was slow. Source
