Pet hair is one of my biggest gripes at home. I have a mixed breed dog that DNA testing confirmed is a mixed breed dog (not a border collie as most people believe) made up of mostly high shedding breeds. This makes it difficult to test the robot vacuum’s power in effectively handling pet hair, which is annoying and easily gets into nooks and crannies that the robot vacuum doesn’t always reach. interesting.

the Dreame L40 Ultra vacuuming and mopping robot is the latest solution to the pet hair pile in my house and I’m happy to say it’s been very successful.

The black and white color of the Sweet Luca means I have to vacuum every day to avoid seeing clumps of gray hair everywhere. Dreame L40 Ultra expertly tackles even corners that other robot vacuums don’t reach with side brushes and mop pads that extend outward up to 20mm.

My home office is where I keep all kinds of review equipment, from portable power stations to smart home devices. It’s also where my dog ​​sleeps, naps, eats, and drinks water. While different items are always coming in and out of my home office, there are two things that are constant: pet hair and chargers.

I’ve never been able to run the robot vacuum every day in my home office because the floor is always littered with charging cables, my dog’s chew toys, and random junk. Robot vacuums often get stuck on these items, so when I run the vacuum daily in the living room, I create a virtual boundary to keep the vacuum out of my home office, then I have to vacuum and clean the house by hand.

The Dreame L40 Ultra vacuum and mop robot has been running on a daily schedule in my home office for nearly a month, keeping the 300-square-foot space clean and free of pet hair with little effort on my part. . This helps my allergies a lot, as even the air purifier in the office runs less because the room has less pet hair and dust.

The robot scored 65% on the pet waste test, mainly because it was constantly pushing pet waste around, which would be disastrous if it were real.
