Central vacuums like the Honeywell 4B H803 come built with a powerful 15-amp dual-stage motor, making it one of the strongest on our best central vacuum list. Its self-cleaning HEPA filter reduces maintenance. And having 125 CFM is rated for homes with a sq ft of 12000. It\u2019s a deadly combination, to say the least.\r\n\r\nWhy We Like It - Honeywell 4B H803\r\nMade of heavy-duty steel, the Honeywell 4B H803 extends its lifespan by incorporating a self-cleaning HEPA filtration system, 125 CFM, and surprisingly quiet operation.\r\n\r\nPower\r\nThe vacuum Honeywell power unit features 630 air watts, in addition to suction power of 128-inches. It operates with 120 volts, which is pretty standard among vacuum cleaners.\r\nSpeed & Efficiency\r\nAll that power gets the Honeywell 4B H803 125 CFM. That means you\u2019ll cover 125 cubic feet every minute. That\u2019s 25 below the Prolux Vacuum in terms of CFM performance. It\u2019s enough performance to adequately clean a 12000-sq ft area.\r\nCapacity & Maintenance\r\nThis 7-gallon dirt devil is holding nearly 50% more in its dirt receptacle than the Hoover Vacuum Cleaner, which comes out to 2 lbs more. Maintenance is kept significantly low due to vacuum bags and a self-cleaning HEPA filtration system.\r\nDurability\r\nIt\u2019s not uncommon for Honeywell central vacuum systems to be sturdy, but a heavy-duty steel body? Honeywell wanted this machine to last several years, which is exactly what you\u2019ll get out of it. And it\u2019s incredibly quiet, only ever peaking around 73db.\r\nValue\r\nThere\u2019s no doubt about it: 4B-H803 Quiet Pro Central Vacuum System Power Units are powerful, and fit perfectly in large areas. Unfortunately, it\u2019s barebones and expensive. You aren\u2019t getting any accessories, not even a hose. If you want H803 Central Vacuum System Power, you\u2019ll have to take an extra step and grab a few accessories. Also, you have to worry about purchasing vacuum bags. The Allegro MU4500 Champion comes with a bevy of accessories.\r\nHoneywell 4B H803 Wrap Up\r\nEven though price is a concern, you\u2019re still getting an excellent central vacuum here. Having 15-amps makes a difference, providing 125 CFM that does wonders on 12000-square foot areas. And its self-cleaning HEPA filtration system reduces the amount of maintenance needed, as do the bags. But to take full advantage of it, you\u2019ll need to invest in accessories and bags. You\u2019ll otherwise not be disappointed.
