What Reddit says
Redditors tend to recommend the Dreame L40s Ultra for pet hair, hard floors, and convenient automated mopping, but are less enthusiastic about its carpet performance and occasional navigation quirks. It looks most appealing at a discounted price, especially for homes with lots of shedding pets. Buyers with extensive carpeting or many cables and small objects on the floor should compare alternatives and check local warranty support before purchasing.

“The Roborock Curv, Dreame vacuums with the tri cut brush as the other person mentioned, and Narwarl Freo Z Ultra are probably the ones you want. Curv and Freo Z have brushes that are designed to pick up the hair and then the hair travels along the brush until it falls of the brush and is vacuumed up. The Dreame one…”From thread: Most durable Robot Vacuum? ↗
“Please correct me if I am wrong, but this actually looks like Berber carpet, not high-pile. Think of high-pile like a shag rug. It's long and can get tangled or damaged by beater bars and the long shag pieces can stifle the suction of vacuums. Berber is thick and dense but this kind of rug would be good with any mid…”From thread: best robot vacuum for high pile carpet? ↗
