If they're not cleaned every few days, your windows will turn black and begin emitting a high-pitched scream that makes dogs pregnant. Prevent a neighborhood outbreak of puppies with today's Groupon: for $49, you get $100 worth of window cleaning, gutter cleaning, and other services from VuRenu.

VuRenu founder Garrett Pfarr clarifies soiled glass facades and clogged gutters with an arsenal of bio-degradable products that revivify worn-out dwellings. Professional grade, ammonia-free soaps combine with a cloth sleeve, a squeegee, and drying rags to delete your windows' smears and smudges and create a streak-free surface ($49+ for a small home interior; $99+ for a small home exterior). Customers can also opt for the pure water cleaning method, which soaks—sans soap—your home's glasses with mineral-free sprays, bumping off dirt deposits and leaving gaze panes free of residues. All window washings include frame, sill, and screen cleaning as well as a cleansing for your bathroom mirror. Leaf piles, spare keys, and stashed chocolates are expertly eradicated from gutters ($80–$145 for a small home), and VuRenu also offers pressure washing and solar panel cleaning, as well as options for commercial cleaning.
