Yes, many cheap hoovers are designed to be versatile and can effectively clean both carpets and hard floors. However, the efficiency of a hoover can vary based on its design and features.
For carpets, look for hoovers with strong suction and a motorized brush roll to agitate and lift dirt from deep within the fibres. For hard floors, a hoover with adjustable suction settings and a soft brush roll or floor nozzle is ideal to prevent scratching and ensure thorough cleaning. It's beneficial to read reviews and product descriptions to ensure the hoover performs well on both surfaces.
