## 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](https://vacuumwars.com/dreame-l50-ultra-robot-vacuum-review)
- 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](https://vacuumwars.com/dreame-l50-ultra-review-3-months)
- 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](https://www.rtings.com/robot-vacuum/tools/compare/dreame-l40-ultra-dreame-l50-ultra/74370/103657)

### iRobot Roomba Max 775 Combo

- Gizmodo: Good vacuuming with no clogs and a streak free roller mop that handled ketchup about as well as rivals, but noisy, a buggy app on long runs, unreliable carpet detection and trapped twice under a bed. A full vacuum and mop of 750 sq ft took about 2.5 hours. [Source](https://gizmodo.com/irobot-roomba-max-775-review-a-respectable-roomba-redux-2000813995)
- Tom's Guide: Hard to recommend. Hardwood pickup of 44% hair, 86.5% Rice Krispies and 91% chia seeds; carpet 52%, 63.5% and 35%. Bumped walls often, scattered debris with its side brushes and left slight mop residue. [Source](https://www.tomsguide.com/home/home-appliances/roomba-max-775-combo-review)
- Xataka: Excellent pet hair pickup and effective hot water roller mopping; cleaned 55 m² in 40 minutes using 33% of the battery. Fixed side brushes made corners less thorough and bags and solution are costly. [Source](https://www.xataka.com/analisis/irobot-roomba-max-775-combo-analisis-caracteristicas-precio-especificaciones)
