The pn5 was a definite improvement over the PN4a. It has a dark gray almost black plastic cover with a medium gray bumper and a silver label with Electrolux on it.

Air flow was better all the way around the opening and had better edge cleaning and a total new automatic height adjustment system were the main features aside from a wider and larger brush roll. A new power nozzle was introduced during the Silverado run and it was an L shaped model much like the current Aerus/Electrolux Lux classic power nozzle and introduced the “Omni-flo automatic” design.

The original power nozzle was painted gray to match and model pn4a it was rectangular in shape. We have 4 Silverado’s in the family.not sure if you got a power nozzle with it.
