Frequently asked questions about the Eureka J15 Pro Ultra
Does the Eureka J15 Pro Ultra empty its own dust bin?
Yes. The station empties the robot’s dust bin after every run. The 3 l dust bag in the station lasts up to 75 days, the maker says.
Does the Eureka J15 Pro Ultra wash and dry its own mop?
Yes. The station washes the mop itself, with water at 167 °F (75 °C). It then dries the mop with warm air.
How high a threshold can the Eureka J15 Pro Ultra climb?
Thresholds up to 0.8 in (20 mm), the maker says. Measure your own thresholds: the ones to a bathroom or balcony are often higher.
Does the Eureka J15 Pro Ultra fit under low furniture?
The robot is 4.3 in (11 cm) tall, so it fits under furniture with at least 4.4 in of clearance.
Is the Eureka J15 Pro Ultra suitable for pet hair?
Yes, the maker says. The brush guides hair to the side instead of winding it around the roller.
How long does the Eureka J15 Pro Ultra run on one charge?
