The freedom of cordless vacuum operation is the main feature that is introduced with a higher price tag. The price bump to get to a battery-powered backpack vacuum is a lofty one, but it affords full range of motion and the maximum in mobility. Warranty lengths and terms tend to increase a bit, in some cases jumping from the common 1-year warranty to a full coverage 3-year warranty. While it’s not guaranteed within a higher price-point product, consumers can expect to find slightly higher-quality materials and attachments in a vacuum that reaches a bit higher on the price spectrum.
