Description

FIELD

This document relates to a glass cleaning device and, in particular, to a glass cleaning device having a replaceable blade configured for curved windows and windshields.

BACKGROUND

Window/glass cleaning is conventionally performed using squeegees or the like. In the past several years, more and more vehicles and buildings are making use of curved glass for windows and windshields. While some vehicles have windshield wipers that are designed to follow the curves of the windshields, there are often areas on the windshield that are not cleaned by the windshield wipers. In some cases, such as on buses, aircraft or industrial vehicles, it can also be hard to reach these areas due to the height or overall size of the windshield or due to the curved nature of the windshield. Similarly, on buildings, there are more and more curved windows that can be hard to reach and are difficult to clean with conventional squeegees.

As such, there is a need for an improved glass cleaning device.
