The additional impact from the battery comes from raw materials and manufacturing, charging losses, lifespan, and disposal. Higher efficiency is of course a good thing, but you can't just look at something as simplistic as average wattage by itself and expect to get any meaningful insight. I...

I think your overall list of factors could use a bit of expansion, but environmental impact is a bit silly to talk about in the context of using battery powered appliances in a residential setting. Batteries are used for portability, not for performance or environmental friendliness lol. Battery...

Well, ignoring things like reliability, ease of use, cost, etc. considering the topic of the thread, I'd argue that what ultimately matters is the time to complete the cleaning job to a certain standard. Good quality vacuums are able to do single pass cleaning for normal applications, so...

We are talking about cleaned path width, which is different than the cleaner head width. Continuous roller brushes that are side driven don't suffer from an interrupted cleaning path. And yes, you should be overlapping cleaning paths at least slightly, and doing so creates a larger addition to...

Cleaning path is too often overlooked. Even just a drop from 12" to 10" will make the job take at least 20% longer. And I don't even know how you could clean efficiently with a head that leaves an uncleaned path in the middle

"Silent Partner" lol. With that high pitched tone, I wonder if it might benefit from new bearings.

You are generating heat because of a high-resistance area. If the only heating of concern happens to the vacuum plug regardless of where you plug it in, then the vacuum plug is the cause of the high resistance. Whether the high resistance is the issue or excessive current is another question...

You would do well to take in and implement some of the feedback you are receiving about your conduct. Not to mention learning to take into account the experience and knowledge base of others.

We're going to need a notarized declaration of facts, as well as images of the original packaging and receipt, plus GPS tracking showing your trip to the store when you purchased it, and a detailed 3D scan of both the interior and exterior. Go ahead and get it MRI'd while you're at it, then we...

It's a bit confusing since there are so many videos of exactly what you are asking online already. I linked one in your other thread earlier, but a quick search on your end would find you several much, and faster than it would take us to go take and upload yet another.

Thankfully reality doesn't depend upon you believing me!

Interesting that the alignment is opposite between the Dyson and Panasonic. Either way, I can't say I like the range of brush-ground interface speed you will get from that when there are other solutions available. Well you can't really get better than no hair tangling when it comes to hair...

Never had any hair tangling issues with my Wessel-Werk EBK 360. Seems like it has a pretty sensible design in that regard. Then again, it's operating with a much higher internal air velocity which must be helping it a bit in that regard.

Wait, does that thing have a conical shape to its roller brush? Odd decision if so.

It's happening...

I'll post about it more here when I've made some progress on it, but I'm redoing the entire control circuit. I have an old CV350 that had the common basic transformer + relay setup, but a few years ago switched that out for a Shelly smart switch. That worked great until my armature failed (I...

Do you have any examples of ones that use a soft start? I was planning on incorporating that into mine, and I'm curious how existing solutions do it.

There are a great many videos you can find on YouTube. Here's the first one I came across, it is turned on at the very end: That's pretty typical for how they sound. They aren't quiet at all—they typically rely on being in an out-of-the-way location like a garage or basement where the noise...

A non-subjective comparison between the motors would be pretty difficult without the old one working, but thankfully I am quite familiar with this machine and can confidently say there is a noticeable improvement in cleaning performance. It's also, surprisingly, much quieter, and the highest...

There is an orifice diameter that will roughly match a system in any configuration you want - hose or not, cleaning head or not. There's not really any way around that fact. In a particular configuration, you will achieve a certain amount of airflow. With a fully open orifice plate, if you...
