Dyson Piston

[Vacuum Facts]

Exaggerated initial mess levels indicate nothing about real-world performance. Such videos are 'entertainment' at best and not informative of any machine's capabilities, even though there's the appearance of loose correlation. It's unfortunate that despite everything out there to understand this, it's still underappreciated. Extreme initial mess concentrations need higher energies to remove quickly. We're moving to lower energies, meaning this kind of 'demonstration' will never yield good apparent results in the future. Real-world mess levels most respectable people would have in their homes can be exceptionally cleaned with very little energy. No one starts with a house full of stones and rocks, or tries to capture 30 days' worth of fine dust in 3 seconds that completely overwhelms separation systems. These videos simply represent someone 'playing in the dirt'.

The actual real-world failures of the V16 are not accurately captured from these videos. These videos are also contradictory: the first suggested good filtration, the second suggested bad (not that anyone noticed...). I'll show how the Gen5's performance can still be achieved with the V16 and, more importantly, why, for real-world mess levels. For the wrong reason, admittedly, it's nevertheless true Dyson shouldn't have released the V16 as they did. The problem seems to be suit-driven rather than the engineering.

It's precisely what it is, @Vacuum Facts, you're right. It's just as you said.

To be honest, even Dyson's demos across each and every major... bruh, also have relative modest messes used to demonstrate their vacuums. On both hard floors and carpets, but especially the carpets. It's completely unlike the extreme initial those stupid videos used. Really, the latter is literally someone 'playing with the dirt' - just watch the videos and see how much of a mess said people forced the machines in question to cope. Who in their right mind actively do all that daily?

@Vacuum Facts yes, it's true, V16's launch is really sloppy, especially for a machine this performant and advanced.

Also, yeah, it's true that all of this can be traced back to suits. The suits, but not in a kind you can wear - rather, it's what's slowly rotting the internal management. That explains the one big mistake in question. That above thread I linked? @Vacuum Facts it's for you! We want to know what to fix the (initial batch of) V16 like the one you're using nowadays.

The V16 has the horrible unswept path, shoots dust out the back and generally just looks like extremely poor pick up and suction/agitation. The hard floor test also is atrociously bad.

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.

An unintended feature, actually. And also, it's not nearly as bad as those belts on old brush bars.

My proposed redesign of the dual-cone head addresses it.

The V16 definitely doesn't shoot dust out of the back. It shoots rocks out when someone tries to pick up an entire driveway laid out on their floor and it gets overwhelmed. High power usage on machines that waste a lot of energy by today's standards might cope, but low energy, efficient models don't, since they're designed for representative, real-world situations.

The unswept path is visually ugly but isn't a significant factor of its out-of-box poor performance. It only appears that way, again, in ridiculous, unrepresenative garbage disposal unit usage that exaggerates the line and makes it look like a practical problem when it isn't. I didn't say it was a feature, I said you can use it as a visual guide to overlap strokes, which should be done for deep cleaning anyway. Interesting how you misunderstood that and portrayed it misleadingly.

I know you want to vacuum quickly, but, as explained in the lecture video I made, deep cleaning is achieved by the amount of time a given area of carpet is subjected to high air speed whilst agitated to prevent entrapment. If the air speed is low, or you move over too quickly, or don't spend enough total time in a given unit area of flooring, the cleaning results will be lower. Having a wider path can help cover the area faster, but doesn't automatically mean it's as clean. This has to be measured directly. I've already provided examples of what good data looks like earlier in this thread, and there's plenty more on my channel for a wide range of machines.
