Do central vacuums loose suction and airflow through the piping? |

I know central vacuums are powerful, but do they lose cleaning performance through the piping? |

Not if the piping is installed properly. As for the hose, it depends on the type (wire-reinforced or crush-proof) and diameter. A larger diameter crush-proof hose is vastly superior to a wire-reinforced hose. |

Wyaple, a.k.a Vaclab on YouTube, demonstrated this years ago on his channel. In my opinion, a high end canister vacuum cleans and filters just as well as a central vac. The only reasons to get central vac is better quality or if you wanted better filtration without needing a HEPA filter on a vacuum's exhaust. However, you have the disadvantage of needing a long, bulky electric hose or using a battery powerhead to clean carpets properly.

Rob, that is true of which any TOL canister can perform just as well as an average central vacuum. And I also agree that I too can care less about the battery powernozzles except for either the Volt or the CX1000. I don't however agree with the hose part. Having used both a canister and a central vac, I find a canister unit more difficult to pull around and/or maneuver than any hose itself on a central. Especially the wire reinforce hoses. In fact when we had our kitchen redone, I used one of the contractor's wet/dry vacs before to clean up and I ended up chipping some paint off of a corner on our drywall. It still bears the scar on our wall to this day. Now to be fair, the wet/dry vac didn't had a bumper on and they're typically not designed to primarily be used for indoors. But the point though being is with any canister unit regardless if it has a bumper on or not, it would have a greater chance of tearing off something of not just drywall but also crown moldings, furniture, etc. With a central vac hose especially with a sock cover hose on, you'd have a FAR less chance of tearing something off. Not to mention that it wouldn't even get paint marks on the sock cover versus a canister which would likely have paint on the cord especially when it gets hot.
Beagledad, I should clarify that in the video it's not just suction alone but any kind of power through the piping. It's not like it completely lost it's power but it definitely decreases as there are more piping throughout a house. It totally made sense to me when I first watched it and that's the first thing it came to my mind when I saw this thread. |

Generally a central vacuum is installed for the size house that's in.
The bigger the house the larger the volume of pipe the more powerful the unit. Especially when compared to a portable vacuum even a central vacuum in a very large house has significantly more power. Here's an example from the canister to the farthest away from the canister in a 5000 ft house. Central Vacuums are amazing every collector should have one. |

I've seen some older central units that use basically a FilterQueen or Tri-Star type motor. I was expecting the power to be worse than the portable machines they shared the motor with, but even when installed in a system, at the end of a long hose and pipe system, it had better power than the portable.
Basically, while being much longer, the air passages are wider than an upright or canister, and the filter/bag setups are usually made with more surface area. The installation itself does definitely matter here too, you could, for example, install a system with all short 90s (these are ONLY supposed to go immediately behind the inlet int the wall) for elbows... This would result in massive airflow loss and very poor performance. Use sweep 90s or two 45s and it works much better, also using a Y fitting rather than a sweep T helps. Hoses can be the worst restriction though. I have hoses that make my massively powerful central system feel like a mediocre canister, think Electrolux Central hose here... But really, central vacs have always performed as well, or better than contemporary canisters (And I believe both canisters and centrals out perform uprights) as they have always, for the good units, had so much power that, even after the small losses that do occur, they are still more powerful than a canister. And the most important thing, the only way to be sure you really have removed the dust is not to have a HEPA filter, but ti vent the machine's exhaust out of the living area. |
