Incredibly the MaxVac arrived this afternoon. I’ve yet to put it through it paces but some initial observations:

1. It’s a good thing it was over boxed because the shipping carton was beat to heck
2. It’s heavier than I expected but not prohibitively
3. The vent hose is difficult to remove and replace in the Systainer. Super tight and I’m worried about the getting torn as the nut for retention screw for the filter retainer is in the same space and rubs against the hose when remove or replacing in the Systainer
4. For $1,000 and knowing they are shipping internationally- they could’ve included a US plug or adapter. They sent both a UK and a EU cable. They cost $3 on Amazon but that’s not the point. Fortunately I had a short NEMA 5-15P to C5 3-Slot Cord Power Supply at home and was about to plug the MaxVac in. I did order a longer 12’ cord which will come tomorrow
5. The sound is comfortable. I powered it on and was still able to have a chat with a person in the next room without yelling.
6. The filter sizes seem to be proprietary which means being beholden to limited sources and significant international shipping costs. Not totally unexpected but worth keeping in mind for those in the States.

I’ll post more as I use the scrubber in the coming days and weeks.


Up until lunch today the u it was working well. I tried to fire it back up this afternoon and the unit won’t turn on. The power button blinks blue and that’s all the unit does. I’ve contacted the seller and will keep you all posted.

Or can anyone tell from the pic in reply #19 if the blades are forward curved or backward curved?

I'm 95% sure that's a forward curved fan blade.
It has lot's of blades sat in a volute housing.
A backwards curved fan has a low number of blades and doesn't need a volute housing to make the fan work.

This is a backwards curved fan rotor:

This has a forward curve design:

I doubt it's going to make much difference for you, considering all the filters you have before the fan.

Thanks, Bob.

The pre-filter really does its job, which I need to replace this week:

Being it's now end of day in the UK; anther day has come and gone with no response to an email or their 'customer service chat'.
It's looking like a buyer beware situation. I'm not impressed with the seller's customer support and given the number of emails I've received with deals and products from them makes it that more infuriating.

I'll given them another day before opening the electronics and fixing this thing myself.

@mcfal12 Really sorry to hear that. I sent them a mail telling them about this thread as I thought they might be interested. No reply to that, either. I hope you get fixed up and receive some kind of satisfactory response - if you don't, I won't be ordering mine as planned.

You were right. The dust clinging on the fan blades (after 8 years of use or longer) is minimal.




New MERV5 & 12 filters (old Merv 12 one on the right) installed:

Snip.

$200, even in Canadian, is an insane amount for a blade guard with hose port.
The dust collection blade guard is worth its keep:

In this stock preparation for 5 drawers, a veneered mdf board (9.5" x 95") was trimmed into pieces for the fronts and sides. The board was first crosscut on the Kapex. After 16 rip cuts on the table saw (including 4 edge cuts), few saw dust escaped from the blade guard. I had the air filtration system turned on, but not wearing a mask.

It’s been two weeks and my service request has gone unanswered by despite multiple attempts to contact them, including by phone. I’ve contacted my credit card company and they advised giving it 30 days and then I can invoke my product protection and dispute the charge. I may go that route… before I do I am going to take a shot at fixing the unit myself this weekend.

Ironically, they have spammed me relentlessly, despite opting out, with advertisements. And even worse- and honestly my motivation for posting this morning- is they sent me an invoice for 157.99 - despite having paid in full at time of purchase.

I accept full responsibility for my choice to purchase a product from this company without sourcing more information. But As I said before, buyer beware.

Be careful with this because if you tampered with the machine, the seller could argue with your credit card issuer that the machine worked well or could easily be adjusted/fixed with a part, etc. if not for your unauthorized attempt. (Credit card companies can reverse any charge or refund even after they appear on the account if they later find the seller on good ground.)

If I decided to get a full refund, I would leave the machine as is.

In a recent purchase, the seller suggested (read: lied) to the online business platform that I had changed the content of a digital device when I escalated the matter for a refund. I took pictures of the device which was still factory sealed, and received the ruing in my favor the next day.

Excellent point. I would counter to the CC company the failure to engage or respond so that I could work with them on this issue - but it is still an excellent point.

Don’t be. I’m glad you did and the product has potential. The company is the problem here. I posted a Google review. Maybe that will get their attention

They have an active Facebook page, so it might be worth posting there as well as your Google review. I think sometimes social media is more effective because you get to bypass a lazy CS team to get your issue heard.

Edit- actually, I see now that someone has commented on their FB page yesterday, pointing to this thread

Thanks for the suggestion. I actually make a point to avoid social media at all costs; but might have to make an exception here.

We'll let @mcfal12  respond whether he feels we've resolved the case satisfactory for him.  [smile]

The issue @mcfal12 experienced was in fact a safety feature in the motor automatically shutting the machine off when the power supply dropped below 110V. This is due to the reliability and stability of the power supply in his area and is not due to a malfunction of the Dustblocker.

It only seems to have only occurred in very limited number of cases and specifically around the NY area. No other cases reported from around the USA or UK that we're currently aware of. If anyone else has had this and not yet reported it, please report this to the manufacturer directly on sales@max-vac.com and they'll look after you well.

MAXVAC are still working on a solution to solve this.

@woodbutcherbower looks like you're located in the UK so won't cause any issues for you.

I find a particularly interesting that, rather than providing me this information in any communication, dust arrest, took the action of posting this publicly before communicating with me. At no time was there a communication pertaining to this being a known problem and The last they communicated with me was a solution was still being worked on.

And while I’m not an engineer, being the engineers, working on this or overseas, I would caution any findings I suggest the power supply in the New York region. One of the most populous regions in the world is anything but reliable.

In terms of has the issue been resolved; I am still without a working unit and as noted no solution has been provided.

As a reader, I find it hard to reconcile these two statements:

"We'll let @mcfal12  respond whether he feels we've resolved the case satisfactory for him."
"MAXVAC are still working on a solution to solve this." (Italics mine)

If the second statement is correct, how can the OP feel satisfied?

In OZ all electric appliances have to tolerate a nominal AC value that changed from 240v to 230v, with a tolerance of +10v and -6v, which gives a range from 216v to 253v. And if you had an older item designed for 240v, the new standard is even more considerably less. Yet I don't recall having ever heard of issues with simple AC devices not tolerating wild swings. Spikes and surges yes, but not normal sags, etc.

Assuming there is a tolerance assigned to US mains, how is the Dustblocker so sensitive to a drop in voltage? Especially as I'm assuming the motor is the main component drawing power, any electronics or control systems will be converted down anyway, and as we all know, electrical motors are about the dirtiest thing you can run on mains, and are very forgiving with fluctuations.

It's very similar in the US.  Somewhere around 10% voltage tolerance.  But having "supply power" quirks isn't usually the voltage level itself, it's the quality of the sine wave, or other transient problems.  And usually out in the boonies- NOT in a major city.

But still, I wouldn't get too wrapped up in the exact wording here- this guy's from CS, not engineering.  They clearly don't know what happened, and are trying to reassure everybody that it's not a wide-spread problem.  Until they actually know, what could they possibly say to us?

If the only affected units are in NY, that's odd- but it's not NOTHING.  They can't be certain that it's due to local "fluctuations", but how else would you explain it?  Things like this take time to narrow down.  At least we know they're aware of it, and trying to figure it out.

They definitely owe mcfal12 a phone call though.

@woodbutcherbower looks like you're located in the UK so won't cause any issues for you.

Whoever designs an appliance to cut out at 110V needs some schooling. With the official lower limit of 114V (120V +/- 5%) at the supply point, allowing for only a 4V drop through the consumer unit, wiring and extension cord is ridiculously tight.

In Europe we have 230 +/- 10%

You can notice a shortened lifespan of Halogen lightbulbs between households. My parent usually have around 223 Volts. At my sister's house it's usually 243V. Halogen bulbs don't last as long there, but do burn brighter  [tongue]

Same here in the UK. Everything (even delicate, super-high end audio equipment) is designed with this tolerance built-in.

Even if this is a “safety feature” it would only render the device inoperable while the power fluctuation existed and not in perpetuity. As not by others, NY is a major metropolitan area and has stable power.

I appreciate all the supportive comments and especially @ChuckS @woodbutcherbower @Coen @luvmytoolsz and @tsmi243

I do wish @dustarrest would’ve communicated directly versus trying to misdirect their forum but now they’ve learned that you all are too bright and vigilant to let nonsense pass.
