Like apartment-building superintendents, computers dazzle us with their vast knowledge of hardware and their plethora of strange keys. Maintain this modern marvel with today's Groupon: for $30, you get a hard-drive cleanup and a computer cleaning in-store at TechsOnTheGo (a $114 value).

TechsOnTheGo keeps motherboards humming with an array of computer repair and maintenance services. The proficient virus wranglers will clear computers' innards of clutter by performing a hard-drive cleanup, which helps systems run efficiently by ridding them of undesirables such as malware cookies and any undigested chewing gum. A thorough physical cleaning of machines then commences, during which the entire inside and outside of desktops or laptops will be cleansed, including machines' fans, RAM slots, and keyboard. All computer services are covered by TechsOnTheGo's guarantee, and the technicians strive to deliver effective service rather than recommending that customers purchase unnecessary replacement products or send computers on intensive meditation retreats.
