What reviewers found
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
- 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
Shark PowerDetect ThermaCharged 2 in 1
- Tom's Guide: Hands on review: carpets looked clean after a full run and mopping lifted muddy paw and shoe prints. First map took about 10 min, but the robot got lost once looking for the dock and air blasts sometimes pushed debris the wrong way. No lab measurements published. Source
- Woman and Home: UK month long test: cleared test debris in 1 to 3 passes, hair did not tangle the rollers, and it reached 80% charge in about 30 min. Mapping an open plan room took about 90 min with two bin empties. Source
