## What reviewers found

### Eureka E20 Evo Plus

- Vacuum Wars (2.46 Vacuum Wars stars): Measured 0.30 kPa suction, 8 CFM, 79% embedded sand, 73% pet hair, 3% hair wrap and about 1,807 sq ft per charge. Finished the studio course in 37 minutes. No dedicated obstacle avoidance and heavy water use when mopping. [Source](https://vacuumwars.com/eureka-e20-evo-plus-review/)
- Garumax (Japan): Home test with a dog and two cats. About 3,000 Pa of the 10,000 Pa max was enough on tile carpet, tatami and wood, and it picked up cat litter on reduced suction. Hair wrap dropped but did not vanish. It avoided bags and balls but struggled with cords and thin slippers. The dock is about 45 cm tall and the mop must be fitted and washed by hand.

### Eureka J15 Max Ultra

- Tom's Guide: Vacuumed 602 sq ft in 72 minutes, leaving 65% battery. Mopping about 350 sq ft took nearly two hours. Skipped about 168 sq ft on one run and caught on lamp wires and carpet corners. Cited $1,199.99 at Eureka. [Source](https://www.tomsguide.com/home/smart-home/eureka-j15-max-ultra-robot-vacuum-review)
- Android Authority: Strong on carpets and pulled pine needles from rugs. No hair tangles. Water tanks needed swapping about every 1,000 sq ft. Mop pads popped off magnetically on bath mats, once four times in a day. Called it the best Eureka it has tested. [Source](https://www.androidauthority.com/eureka-j15-max-ultra-review-3599189/)
