Ranked #7 in Best Robot Vacuums

Roborock Q7 M5+

3.5

3 sources$249.99as of Oct 11

The Roborock Q7 M5+ is an entry-level robot vacuum and mop combo that delivers strong performance for its price point. It excels in suction power and carpet cleaning, while its LiDAR navigation provides efficient mapping and cleaning paths. The inclusion of an auto-empty station with a 2.7 L disposable bag is a significant advantage, though the mopping system lacks automatic lift-over-carpet functionality. It's best suited for users seeking value in a budget-friendly model that still offers robust cleaning features and reliable navigation, though those with heavy pet hair concerns may find the brush roll issues limiting.

Strengths

— Excellent suction power with 10000 Pa suction
— Reliable LiDAR navigation system with multi-level mapping
— Includes auto-empty station with 2.7 L disposable bag for hands-free debris collection

Watch-outs

— Struggles with pet hair tangles, with 43% of long hair wrapping around the brush, per Vacuum Wars
