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 X50 Ultra
- Vacuum Wars (3.60 Vacuum Wars stars): Removed 83% of embedded sand and 98% of pet hair with 0% hair wrap and avoided 20 of 24 obstacles. Dried stain score was 80 against a 94 average. Estimated coverage was about 1,130 sq ft per charge. 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
