Window Mates® are a magnetic window cleaner.  Their heavy duty durable frame encases specialized magnets designed for this specific use.  The actual cleaning is achieved by placing a detergent and water soaked Window Mate® on either side of your glass.  Holding the handle and then sliding the Window Mates® in the direction of the arrow (imprinted on the unit) will wash and dry both sides of the glass all in the one motion streak free, thus drastically reducing the time spent cleaning. 
Cleaning multi-storey building windows is no longer a problem, as the Window Mates® are ideal for cleaning hard-to-reach outside windows (providing you have access to the exterior of the window) while remaining indoors.  A safety cord attached to the external half of the unit provides protection against accidental dropping.  It is important to note that the Window Mates® completely eliminate the need for use of harmful chemical or toxic substances often associated with cleaning.  All you need is water and washing up detergent and clean, sparkling, streak-free windows are only a step away!
The Window Mates® come in three models; Single Pane Glazing (Yellow) and Double Pane Glazing (Blue).  Single Pane Glazing Window Mates® are designed for use on single pane glass windows up to 12mm thick.  Double Pane Glazing Window Mates® are designed for use on double or multi pane glass windows up to 24mm thick and European Double Glazing (Purple) designed for 28mm low E glass
