The easiest and fastest way to clean a house is to hire a professional to do the cleaning service. More than professional cleaning supplies, professional cleaners have a world of experience most of us don’t. This allows them to move through a house much quicker. Most professionals can complete house cleaning within 2-3 hours, whereas someone without that experience may take 5-8 hours to do the same quality of work.
Suppose the affordability of a professional cleaner is a consideration. The best thing to do is to clean/dust from top to bottom. Meaning dusting higher selves, then countertops, then floors. Focus on the more essential payoff items that make the most difference. Sweeping, mopping, vacuuming, making beds, clearing out the dishes, and wiping down the countertops. While not being a complete professional cleaning, these items will significantly impact how the space looks.
