Overview
- Recent tests find that inexpensive robots succeed when buyers pick a model built for one main job rather than expecting every feature in one device.
- The Roborock Q7 L5+ pairs LiDAR navigation and an auto-empty station with about 8,000 Pa of suction, which cleans hard floors reliably but offers weak mopping and requires replaceable dust bags.
- The Dreame D20 PRO Plus delivers very high suction at roughly 13,000 Pa and excels on carpets and pet hair, but it lacks an auto-empty station and a mopping function so users must empty the bin frequently.
- The Xiaomi X20+ includes a multifunction dock that refills tanks, washes and warm-dries rotating mops for true automated mopping, yet its ~4,000 Pa suction is too weak for many carpets and pet hair.
- PC-WELT documents broad Amazon discounts across budget to premium models and reiterates practical buyer benchmarks—aim for 4,000–5,000 Pa for hard floors, ≥8,000 Pa for carpets or pets, and prefer LiDAR or an auto-empty station if you want lower hands-on maintenance.
