The figure that matters on the L40 Ultra Gen 2 isn't the 25,000Pa headline, it's the side brush and mop that slide outward past the edge of the robot. Pet hair collects where a round vacuum can't reach: along baseboards, under the toe kick, in the corner behind the food bowl. An arm that extends on purpose is the most useful idea in this group, and it's why this is our pick for a home where pet hair is a daily problem rather than a weekly one.
Suction is the highest here, and it's put to work with four carpet modes: lift the mop and boost suction for rugs, or route around them altogether. On hard floor the airflow plus the rubber brush lifted what our broom left behind. The dock finishes the job by emptying into a bag, washing the mop pads and drying them with hot air, so nothing sits damp in a bucket between runs.
Obstacle avoidance is the part we care about most with animals in the house. A robot that nudges a full water bowl across the kitchen, or finds an accident at two in the morning, creates work instead of removing it; this one steers around shoes, bowls and cables rather than plowing through them. Battery is rated at 231 minutes, the longest in this group, and the map holds more than one floor.
What you give up is space. The dock is a tall unit, listed at just over two feet for the whole assembly, so measure the gap before you plan to tuck it under a counter, and in a small apartment it will be the biggest object in the room. If the dock has a home and your floors are hard or low pile, there is very little to argue with.
Bottom line: If pet hair is the reason you're shopping, this is the machine we hand people: the strongest suction here, a brush that reaches into corners, and a dock that washes and dries its own mop.
