Cordless Back-Pack Vacuum?
« on: July 30, 2020, 12:11 PM »
I have a fairly big shop and I think it would be quick/easy to tidy up with a cordless vacuum that that didn't require me to hold it with one hand while I vacuumed w/ the other.

Do you know of a high-quality device like that? Anything you'd recommend?

Makita makes one.

I wonder if it's any good. Reviews aren't stellar. I have a bunch of Milwaukee batteries, but theirs is crazy expensive and not well-reviewed, either.

One that comes to mind is the Nilfisk GD5.

https://new.nilfisk.com/en-au/products/vacuum-cleaners/commercial-vacuum-cleaners/dry-vacuum-cleaners/gd5/p_906%200605%20010/

Kärcher makes one as well. BV 5/1.

I can't say anything on availability on the North American market.


Kind regards,

Milwaukee has one as well.

https://www.milwaukeetool.com/Products/Power-Tools/Vacuums-and-Fans/Compact-Vacuums/0885-20

Nilfisk and Kärcher, both of the Models are from their Professional range - so that pretty much guarantees you're getting reliable vacuums. No idea where Milwaukee/ Makita stand with their models.

They are available (and expensive). But they look top-notch.

Have you considered back-pack but corded? You'll still have free hands and could plug in a centrally located outlet, preferably overhead. Cordless vacs lag behind in suction, and that's the reason for poor reviews. It will continue to be the case for quite a while. There is no magic. For a competitive performance you need to pull some 1000W non-stop for half an hour. Regular tool batteries can't match that.

I think I'm going to have to. When I compare the specs, they are remarkably pro-corded.

expensive and top-notch are usually found together. :-)

But not always, sometimes (more often than we would
like to) you'll find expensive and junk in the same item.

I’ve heard the Makita is fairly good. But, as mentioned it’s fairly expensive as well, and small capacity (2L).

The CT-SYS is corded, but with a detachable top and a shoulder strap, in which the main unit can be worn as a sling bag it is very useful. And for all it’s capabilities it’s pricing is not too bad..

I have used a Milwaukee  vac for some years now, even connecting my festools.  I now also have a Metabo.  All vacs cordless vacs go through batteries while working quite well.  I also use Milwaukee's 18v lawn tools and the blower also goes through batteries.  The new high capacity batteries extend run time, but vacs and blowers really suck present state batteries.

I have one of those already, so I might try that first.

Rokamat has one that's powered by the Cordless Alliance (i.e. Mafell, Metabo, Eisenblaetter, Starmix, Eibenstock, Rothenberger, Collomix et.al).

https://rokamat.com/en/produkte/staubsauger/wireless-rucksack-vacuum-cleaner/

@ 500w input, 7 kg weight & 15 L capacity, it's bigger, more powerful & undoubtedly more expensive than most.  Nor am I sure that it's available locally for you.  At least the batteries will be easy to find!

I'd love to get my hands on one of their cordless concrete pokers.

I think that's for the whole kit & kaboodle:  Vac, wall sander, pads, batt & charger.

It's only a "mere" US $2K! or so for the vac.  A mere trifle!!

You could also save a fair swag by maybe getting a naked vac, a Metabo charger & a couple of 8.0 AH Li-HD batteries instead of the badge-engineered OEM items (which cost an insane $600 odd).

So, all up, a snip at about $1600-1800.  Mere chickenfeed.....

I'd start with requirements. A regular general cleaning household vac pulls ~120 cfm (56 l/s) and has ~100" (254 cm) static pressure. Can any cordless deliver anything close to that?

This article does not have specifications, but does have a helpful graphic showing the relative capabilities of a typical $150 cordless vacuum, $150 plug-in vacuum, and $400 plug-in vacuum:

The bare tool Makita can be had for about $300 if you’re a patient sleuth.  It’s bagged but the capacity is small.  I’m on the hunt for any cordless dust extractor/vac that has reliable and good reviews.  All of them (18 or 36v) are in the 50-80 cfm range... a bit concerning.
