A well rounded all in one robot that Vacuum Wars ranked #1 at review time, with top five carpet pickup, perfect pet hair results, strong obstacle avoidance and record threshold climbing. Battery coverage is below average, and a long term tester saw weekly dock clogs with a heavy shedding dog. The 3 year warranty is a real plus at this price.

A good fit for homes with low beds and sofas, since the 3.14 in body has no LiDAR turret. The dock does nearly everything, but you still fill and empty water tanks every few runs. Skip it if your floors are covered in black cables or if the store is out of stock and the price is high elsewhere.

What reviewers found
Dreame L50 Ultra
- Vacuum Wars (3.84/5): Measured 90% carpet sand removal, 100% pet hair pickup, 20 of 24 obstacles avoided, a 211 point mopping score versus a 188 average with 0.35 g of water left, and a 42 mm threshold climb; coverage was below average at about 823 sq ft per charge. Source
- Vacuum Wars (3 month test): After three months of daily use with kids and a heavy shedding dog, mapping and obstacle avoidance held up, but hair formed clumps, the dock and bin clogged about once a week, and the app did not warn of clogs. Source
- RTINGS: In RTINGS' comparison with the L40 Ultra, the L50 Ultra handled pet hair better and had stronger obstacle avoidance and threshold clearance, while the L40 Ultra cleaned hard floors and carpet better. We could not read RTINGS' numeric scores. Source
Roborock Saros 10R
- BGR: Called it Roborock's best model at launch. It fit under sofas and beds, had about 57% battery left after about 80 minutes of vacuuming and mopping, and needed tank service every four to six cleanings. It tangled in cables until a no go zone was set. Source
- TechRadar: Noise measured 62 dB at source and 55 dB at 10 feet. Oats were cleared but flour stayed in floor seams on Max and Max+. It cleaned a syrup, soy sauce and milk spill in one pass on low water and mapped five areas in about 5 min. It rode over a 1 inch dog bone until Pet mode was turned on, and the dust bag filled in about three weeks. Source
- Vacuum Wars (3.64 Vacuum Wars stars): Picked up 80% of embedded sand from medium pile carpet against a 75% average and 92% of flattened pet hair, with 0% hair tangling. Avoided 24 of 24 obstacles. Cleared 20 mm and 26 mm boards but failed a single 36 mm threshold. Estimated about 1,389 sq ft per charge. The onboard bin is 270 ml. Source
