What are the types of vacuums includes both scientific vacuum classifications and types of vacuum cleaners for household use. For vacuum cleaners, main types include upright vacuums which stand vertically with motor and dustbin together, good for deep carpet cleaning, canister vacuums with separate canister unit connected by hose, good for hard floors and stairs, stick vacuums which are lightweight cordless or corded, good for quick cleaning, handheld vacuums small portable for spot cleaning, robot vacuums autonomous with sensors and mapping for automatic cleaning, backpack vacuums worn on back for commercial cleaning, wet dry vacuums that can handle liquids, and central vacuum systems built into home with outlets. For scientific vacuum types classified by pressure level, types include low vacuum, medium vacuum, high vacuum, ultra-high vacuum, and extremely high vacuum, each requiring different pumps. Also types by pump technology include positive displacement pumps, momentum transfer pumps, and entrapment pumps. So when asking types of vacuums, you could mean cleaner types for home or vacuum pressure levels for industrial and scientific use, both with distinct classifications.
