The Volkswagen-branded e-bike from n+ Bikes is promoted around a suite of safety technology including a rear camera, radar, smart glasses, a connected helmet and handlebar displays. When a Gizmodo reporter tried the bike at IFA 2026, however, the battery packs had not arrived at the venue because of a logistics delay.

Without the battery, the powered riding experience and most of the headline electronics could not be tested on the bike. The technology-heavy e-bike ended up being ridden largely as an ordinary bicycle.

The runway at IFA 2026 featured humanoids and quadruped robots rather than human models. During the September 5 “Robots on the Runway” event, machines walked the stage, struck poses, danced and performed moves including backflips.

IFA’s official program listed participants such as Primebot Robots, EngineAI, Dobot, DEEP Robotics, AgiBot and Unitree. Instead of limiting the machines to booths and specification sheets, the event presented their sensing and motion-control abilities as a live runway show.

A space normally built around clothes and human presentation thus became a robotics demonstration. Once machines acquired humanlike bodies, apparently one of the next tasks waiting for them was learning how to make an entrance.

Robot vacuums work well on flat floors, but stairs stop them completely. Saros Rover tackles that problem with wheel assemblies that extend like legs, letting the machine lift itself one step at a time. It was demonstrated at IFA 2026.

The robot carefully raises its body onto each tread and cleans as it goes, taking about three minutes in the demonstration. Rather than being carried upstairs by another device, the vacuum itself performs the climb.

Larger robot vacuums can struggle to fit beneath furniture and into other tight spaces. Roomba Duo tackles that problem with a large cleaning robot that carries a smaller companion robot and lowers it to the floor using a mechanical arm on top. iRobot presented the two-robot system as a concept at IFA 2026.

The main unit handles regular vacuuming and mopping, while the roughly 8.35 cm-tall companion can enter places the larger robot cannot. Both share the same home map, dividing the job between two machines of different sizes.

Robot mowers often struggle to trim right up against walls and lawn boundaries. The H510 Pro tackles that limitation with a mechanical arm that moves its main cutting disc outward by about 7.4 cm. The system was shown at IFA 2026.

EdgeSense identifies different boundary types, and when needed the mower physically reaches the blade toward the edge. Side guards and people-and-animal detection handle safety while the machine solves the last few centimeters of mowing in an unusually literal way.
