Sealed suction is easier than airflow for central vacuums since there is no pressure loss in the pipes and hose when there is no airflow. Central vacuums commonly do 100+ in.H2O. The motor I just put in mine is rated for 152 in.H2O, although I'm not getting quite that right now since I have some...

I'm not talking about a difference in restriction between the two, I am talking about the intentionally created restriction that directs the airflow to the area being cleaned. That particular restriction can definitely be assumed to be the same between the two types of vacuums.

The efficiencies will also give you a vague comparison of waste heat generated by the units. I'd generally expect a more efficient motor to last longer, especially regarding harder to repair heat-related failures. I wonder if a shift toward brushless is going to happen any time in the near...

Personally, my favorite thing about central vacuums is that you can vent the exhaust air outside, but regarding performance, yes, you will be getting more cleaning power at the end of the hose in most situations. Usually when using a vacuum, you will be creating a restriction around the area...

Totally a non-issue. A feature, really. Just make sure to wear your Dyson® Zone™ headset when vacuuming.

Some are narrow, but most are just areas under things like desks or beds. You are right though, I suppose you could crawl around with a crevice tool in those areas. But personally I'd rather just use a vacuum with a straight cleaning head.

There are several areas in my house where you can't run along a wall. I imagine I'm not alone in this.

Quantifying them doesn't matter a whole lot for comparative testing. The test slots and debris won't match the vast majority of actual use cases, but if one vacuum removes the test debris from larger slots than another, then you can expect that the former will perform better at removing real...

I like his test with the board with slots of increasing depth. Seems like a very repeatable and measurable way to compare cleaning-relevant performance without tying the test to a specific floor type. But if he standardized the speed, made the board wider and vacuumed in the middle to reduce...

That's surprising that a main motor of that format wouldn't use ball bearings. If they are just sleeves, I usually go with 3-In-One motor oil (not their multipurpose oil), unless there's a good reason not to. It's a little more viscous than typical sewing machine oils. If they are ball...

I don't know why you would bother to pretend that you aren't intentionally making personal attacks left and right. You hide your profile in an attempt to make the patterns of your behavior less obvious, but that's not a very effective method on a forum this small. Your ill-reasoned and...

While I agree with the general sentiment that he should change his conduct if he wants to continue here, you post is not the way to accomplish that. There are plenty of legitimate issues with him that you can describe objectively without dropping to his level by slinging insults around and...

So your response is 'nuh uh'?

I just noticed how pointy the front is. Don't think I've ever seen that before. Doesn't seem very good for cleaning close to walls in places where you can't just run parallel to the wall.

It's hard to find an plug that doesn't look terrible, although it does give you the option to put a 90° plug on, which is almost always better imo, and lasts longer. I also prefer NEMA 5-15P receptacles to be installed with ground on top, but the selection of 90° plugs that work with this is...

The extra current isn't your problem then. 12.3 A will generate 5% more heating than 12 A and will generate less than a 5% increase in the difference between the conductors and ambient temperature. For the type of cables/connectors that these types of devices *should* have, a properly sized and...

It's pretty comical to see the defense of being forced to inch along as you vacuum. If only there were some technology to have a continuous brush roller... Although you do have a great point about a wider path not necessarily meaning the path is cleaned sufficiently. All things equal, wider...

But @Vacuum Facts assures me that the unswept path is more like a feature that helps you overlap your passes, and that not wanting to vacuum 4" at a time is a skill issue or something like that.

For a well installed system, I don't think the ideal power of the power unit corresponds very well to home size, for the vast majority of homes at least. There losses in pipes in the walls should be relatively small compared to the hose and cleaning head/attachments. That's interesting. I...

The modern one I have the most experience with is Wessel-Werk's EBK 360. I like it, but there's a lot of room for improvement. Pros: Cleans well and reliably - single pass is almost always enough Motor is more than powerful enough Belt wears pretty slowly (lasts at least as long as the roller...
