Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits.

Common uses include water, sewage, agriculture, petroleum, and petrochemical pumping. Centrifugal pumps are often chosen for their high flow rate capabilities, abrasive solution compatibility, mixing potential, as well as their relatively simple engineering. A centrifugal fan is commonly used to implement an air handling unit or vacuum cleaner. The reverse function of the centrifugal pump is a water turbine converting potential energy of water pressure into mechanical rotational energy.

A carpet beater or carpetbeater (also referred to as a rug beater or rugbeater, carpet whip, rug whip, clothes-beater, dust beater or dustbeater, carpet duster, wicker slapper, rug duster, or pillow fluffer, and formerly also as a carpet cleaner or rug cleaner) is a housecleaning tool used to beat carpets in order to shake dust and dirt out of them. It was in common use until the vacuum cleaner became widely affordable.

Typically made of wood, rattan, cane, wicker, spring steel or coiled wire, antique rug beaters have become very collectible. Modern mass-production versions can also be in plastic or wire.

A carpet sweeper is a mechanical device for the cleaning of carpets. They were popular before the introduction of the vacuum cleaner and have been largely superseded by them. However, they continue to be used in many home and commercial applications because they are lightweight and quiet, enabling users to quickly clean small messes up from the floor without disturbing patrons, patients, babies and pets, and because they do not require electricity to operate.

Hot Water Extraction (HWE) is a method of carpet cleaning. It involves a combination of hot water and cleaning agents being injected into the fibers of a carpet and the lifted soil being removed by a vacuum. It is sometimes called "steam cleaning".

A robotic vacuum cleaner, sometimes called a robovac or a roomba as a generic trademark, is an autonomous vacuum cleaner which has a limited vacuum floor cleaning system combined with sensors and robotic drives with programmable controllers and cleaning routines. Early designs included manual operation via remote control and a "self-drive" mode which allowed the machine to clean autonomously.

Marketing materials for robotic vacuums frequently cite low noise, ease of use, and autonomous cleaning as main advantages. The perception that these devices are set-and-forget solutions is widespread but not always correct. Robotic vacuums are usually smaller than traditional upright vacuums, and weigh significantly less than even the lightest canister models. However, a downside to a robotic vacuum cleaner is that it takes an extended amount of time to vacuum an area due to its size. They are also relatively expensive, and replacement parts and batteries can contribute significantly to their operating cost. Concerns over privacy and security have also been raised around robotic vacuums.
