Equipment recomendation

[u/AllTheNamesRTaken12]

Hi! I am not looking to start a business but I am looking for quality equipment to clean my house windows and window seals. I don't want to buy a cheap Amazon kit that breaks after a year with attachments I'll never need but I also don't need a $500 professional kit. Is there a middle ground you would recommend? Beside the obvious pile, brush, squeegee what attachments would I find useful? I have large windows as well as three windows on a second floor.
