Robotic vacuums combine sensors and robotic drives with programmable controllers. They are smaller and lighter than traditional upright vacuums. Main advantages include low noise, ease of use, and autonomous cleaning
Cleaning agents remove dirt, stains, odors and clutter on surfaces. Acidic cleaners contain mineral acids for scaling removal. Alkaline cleaners use strong bases like bleach and ammonia. Neutral cleaners are pH-neutral based on non-ionic surfactants. Scouring agents contain abrasive powders for polishing
First manual vacuum cleaner invented by Daniel Hess in 1860. First powered vacuum cleaners appeared in late 19th century. James Spangler invented first portable electric vacuum in 1908. Hoover Company founded in 1908, producing first vacuum cleaner
Dishwashing liquid evolved from washing soda before detergents were invented. Modern dishwashing detergents contain surfactants and water as main ingredients. Surfactants reduce water surface tension and remove grease and food particles
pH scale ranges from 0 (acidic) to 14 (alkaline). Neutral pH is 7, acidic pH is 0, basic pH is 14. pH affects cleaning effectiveness by removing different stains
Length ranges from 1.5 to 2 inches. Has red-brown color with amber glow. Features shiny exterior and long wings. Prefers warm, humid environments above 82°F. Lays eggs in cylindrical brown cases that turn black after 1-2 days
