Picture above omits vertical tape strips needed to hold the plastic in place; see the post at robotreviews.com for full details and more pictures.
The side bumper extension is for lamp bases. The furniture leg traps are due to the "wheelie" (motorcycles) problem fixed by limiting the wheel extension with cardboard in the wheel well. Same thread at robotreviews. When rubbing furniture legs the unit tilts up activating the sensor for picking up off the floor, shutting down. New units 9350 last year added counter weights in the front.
I do not understand the remark about it being high (haute), up away from the floor -- language issue? There is a separate problem with some robots where the bumper is too high off the floor, allowing the robot to climb on top of things which trap the robot. The Samsung bumper was low enough to engage the lamp bases except there was no bumper at all along the side; it swipes the side against things, turning. It is also possible to lower the edge of the bumper by attaching a plastic strip with foam mounting tape, but this did not seem necessary in my situation. (Plastic from wall corner guards in hardware store; bends into shape.) I also raised the base of one lamp on a finished wood disk cut to fit, decorative.
In other threads here the Neato robots are reported getting stuck on chrome bar stool pedestals. I tested this with the Samsung with no similar problem. The larger size may make the difference. Also Samsung has IR proximity sensors in the front. The sonar sensors in the Vorwerk VR200 version of Neato may work the same.
See the new 2017 Samsung 7000 series Powerbots for more improvements. Shutter over intake for corner cleaning, pet hair cutters on the brush guard. Not yet in Europe but it has just reached the U.S. It should be arriving in Europe soon. Check the Samsung website for your region.
