Roborock Q5 vs Dreame D9 / Roborock Q5 Max: Q5 wins for pure vacuuming under $300

The Roborock Q5 is the best bang for your buck if you only need vacuuming — it has LiDAR mapping, strong suction, and decent app control for under $300. If you need mopping, the Dreame D9 or Roborock Q5 Max (often $280-300 on sale) are better, but the Q5 is the most reliable choice for straight vacuuming.
