We know the ProTeam Backpack Vacuum ($401) isn't the most beautifully designed vacuum cleaner on the market, but you shouldn't count it out. Since the vacuum is styled like a backpack, you can easily carry it anywhere around your house. Its telescoping wand also makes it extremely easy to vacuum stairways, cabinets, countertops, and more. In addition to its efficiency, one person said they were surprised to find its 66dB noise level is "quieter than conventional vacs."
