In all seriousness, I'm a bit camera-shy...

...But two days ago, I put my fears aside and made my first YouTube "Vacuum Video"!

This YouTube video features my Royal/Stark M570 Hand Vacuum, which I recently acquired. - The Stark M570 is essentially a Stark-Branded variant of the Royal M5000 Hand Vacuum. (The only difference AFAIK is the lack of 'Royal' branding on the cloth bag.)

Upon receiving the Stark M570 Hand Vacuum in the mail... I completely disassembled it for a thorough cleaning & hand-washed the cloth bag w/ my favorite Persil laundry detergent (Thank You to the VacuumLand members who gave me advice on how to best wash the bag & prevent the steel ring from rusting!)...

...While the bag was drying, I disassembled the motor to gain access to the front bearing assembly so I could saturate the wool packing surrounding the Oilite Bronze sleeve bearing with oil (Using "3-IN-ONE" SAE-20 Non-Detergent Electric Motor Oil) & did the same for the rear sleeve bearing. - Which by the way, is *MUCH* easier to access than the front bearing... And leaves me wondering why Royal decided to omit the user-serviceable oiling ports on later models of Metal Hand Vacs.

The original plastic fan had a small chip in one of the blades, which probably wasn't anything to worry about... But because I already had everything apart, I made the decision to replace the damaged fan with a New-Old-Stock plastic fan from my parts stash.

With everything cleaned, the motor bearings oiled, brushroll bearings oiled, and the bag thoroughly dried overnight - I reassembled the vacuum with a new Genuine Royal belt & was anxious to try out my newly-acquired + newly-refurbished Vintage 1996 Royal/Stark M570 Hand Vacuum!


Please come check out my YouTube Video on this Vintage 1996 Royal/Stark M570 Hand Vacuum to see more & watch as I vacuum with it for the first time! 🤗⤵️



Hopefully you guys (and gals) will enjoy my YouTube video!

This is my first time ever making a video like this, so please let me know what you think! I look forward to reading any & all feedback, criticism, comments and/or suggestions my viewers & fellow VacuumLand members may have for me.

Hopefully I can get better at making videos like these & get more comfortable in front of the camera - because in all honesty, I enjoyed making this video. In fact, as soon as I'm done refurbishing one of my other vacuums, I'll probably make another video like this one!


What do you think?

Would you guys enjoy seeing more videos like this in the future?

-OR- Would you prefer to see videos that focusing on the actual repair/refurbish process itself, with more of a "How-To" element?

-OR- Would you like to see BOTH types of videos?


Please Enjoy & Thank You!

Cool!

I've wanted to collect Starks for a while. There's not too many rebadged Royals, so when Royal made a deal with a vacuum shop- Starks, it was very cool to see what they had. This little prince, a power team, and upright from the same time matching would be a very cool stark lineup. In terms of future videos, I'd love to see footage of you just doing restoration and repair process. Also, I was very impressed by your bag seal find. I definitely recognised that material and that royal had used it on some other products, I plan to buy a seal or two from you at some point. Upgrading classic vacuums is something I find quite fun, like improved airflow fans, higher amperage motors, hepa bag, and well better seals. Dirt Devil and Royal are my favorite companies to collect. Such cool and good designs when they were their own real company.


 


Best regards, Garrett
 
Nice video! I love these machines and especially the burgundy 5000 style.

That gray fan appears to be made to rotate the opposite way, based on the curvature of the blades. I bet the original fan with its deeper blades curved for the rotation of the Prince's motor would perform significantly better, but maybe not.

I wonder how old of a Prince you would have to find to get a metal fan! Maybe 80s or almost certainly 70s. That would be a cool upgrade!
 
RegularRhett69 - When I originally bought this Stark M570, I had been on the hunt for a Royal M5000 in good condition for some time... and through my research I already knew that Royal had produced a number of vacuums for Stark, so I knew I absolutely *HAD* to buy that M570 as soon as I laid eyes on it.  -  Especially because prior to finding my Stark M570, I had only ever seen one other Stark M570 posted online!  I absolutely couldn't pass up the opportunity to own part of Hand Vac History!


 


RegularRhett69 - Also! I plan to get those replacement bag gaskets posted online later today! - I was hoping to have them posted & available to VacuumLand members much sooner, but unfortunately I found myself much busier than anticipated this week - so I apologize to you for the delay in regards to the availability of Bag Gaskets.


 


 


CentralVacs1928 - The gray plastic fan that you saw in my video was the fan from a Dirt Devil m103.  I was merely using it as a comparison to the black plastic fan out of a Royal M501/M5000, or in this case, a Stark M570. - You are absolutely correct though! The blades on the gray Dirt Devil fan ARE facing the opposite direction of the blades on the black plastic Royal Prince fans!


 


I never knew this until I actually began tinkering with them, but the motor in Royal Prince hand vacuums rotates in the opposite direction of the motor in Dirt Devil hand vacs... or Vice-Versa, since the Royal Prince technically came before the Dirt Devil.  -- Prior to owning my first Royal Prince hand vacuum - which was actually this Stark M570 - all I ever knew was Dirt Devil hand vacs... so the first time I installed the belt in my Stark M570, I installed it like I always did on my Dirt Devil hand vacs, and it popped off as soon as I turned the motor on!  After that happened twice, I tried installing the belt the opposite way, and it stayed on.  So that was the first time I actually realized the motors in Royal Prince spin in a Clockwise direction & Dirt Devil hand vac motors spin in a Counter-Clockwise direction. -- Which explains why the fan blades are facing the opposite direction on Dirt Devil fans, in comparison to Royal Prince fans.


 


CentralVacs1928 - I actually do have two of the original Cast Aluminum fans from early Royal Prince models.  I honestly don't know how much of an upgrade the O.G. cast aluminum fans really are over the black injection molded plastic fans... as I've read discussions from VacuumLand members talking about how the Plastic Fans on Royals & Kirbys are more resilient than their cast aluminum counterparts.  I don't have any scientific data on this, but as far as Royal Prince hand vacuums go, I genuinely feel that the fan is the weakest part in that whole vacuum & is more likely to break than any other mechanical part in the entire Royal Prince vacuum.  -- I will admit that I did install one of the O.G. cast aluminum fans in my "Daily Driver" '95 Royal Prince 501 that I use most frequently.  I'm not sure if the cast aluminum fans are, in reality, weaker or stronger than the black plastic fans, but I figured I'd give it a try and see how it performs.


 


That being said, because I love my Royal Prince hand vacuums SO MUCH, I try to be extra careful when I'm vacuuming so I don't suck up anything that could potentially damage the fans in any of my Royal Prince hand vacs... because although I'm fortunate enough to have a couple of replacement fans on-hand, I'll be hard-pressed to ever find another replacement fan, short of buying a whole Royal Prince & tearing it down for parts. -- Needless to say, I *really* don't want to break or damage any of my Royal Prince fans... Which is why I'll often cringe when I hear the metallic "TING!" of something hitting the blades of the cast aluminum fan I installed in my 1.8 amp '95 Royal Prince.


 
 
Thank you!

I just wanted to thank you for posting your video of disassembling the Royal Prince 501 on YouTube. It is so thorough and well explained. I took an old machine I designated for parts and rebuilt the motor following your instructions. I just got a very rare Dirt Devil all-metal 501-D and I think I may rebuild the motor following your video. Just a tip if you want to take your hand vacs to the next level, a polish using metal polish and an electric buffer will bring them back to a near new finish!
 
Okay

I will try to remember once I get it all cleaned up I plan to sell it on eBay as I really have no use for it since I have a NOS 501 Prince in the box and a Dirt Devil 103 that I use for stairs. I had never heard of them or seen one until I saw a post on here about a month ago and then lo and behold I came across one.
 
Wow, that is pricey!

I knew the retail of the regular 501 Prince in the mid to late 80’s was around $59.99. If you adjust for inflation $79.99 in 1993 would roughly be $175 in todays money! That is pretty salty for a hand vac especially a Dirt Devil branded one purchased at Target. I guess that explains why they are so rare, if I was going to spend the money I would have rather had the Royal brand and bought it at a vacuum shop where I would be more confident they would service it even though this is basically the same unit as the Royal Prince 501. I wonder if the Royal unit was the same price by the early 90’s? I can’t imagine the Dirt Devil variant costing more even if it basically had all the same part content you would think they would have priced it a little less than the Royal. Do you know what the plastic 103 and the like Dirt Devil hand vacs were selling for at this time? Obviously they are not made as well but they are very robust hand vacs as well.

Tyler,

In that same ad, the basic 103 w/o the tools was just $34.99 while the 500 and 510 with the tools went for $39.99 and $44.99.

The NASCAR special edition, model 504, retailed for $39.99.

The respective regular prices were:
510: $49.99
504: $49.99
501D: (drumroll)... $88.99!

My guess is the standard-issue 501 would probably have went for about the same $88.99 in vac shops. Ditto for the burgundy-trimmed M5000 version.

Tyler, I love the look of your Dirt Devil 501D Hand Vacuum. Especially the colour scheme they used, very stylish. However, it's a shame that Royal never thought of making the Dirt Devil version it's own bag with Dirt Devil lettering on the bag instead of just putting a standard Royal bag on it.

However, that is such a nice hand vacuum, and rare enough, I would consider keeping it if I was you. That's truly a RARE find you don't see everyday, and one you might later regret selling.
 
I Agree About the Bag

I also thought it was a little strange they chose to use the same basic cloth bag design as on the 501 Prince in a different color scheme but they did not use the Puff Paint on the red portions as in the Royal 501. I’m guessing it was a last minute idea to try and boost sales. I’m not a collector so I won’t regret selling it. I have a few vacuums, mostly Royal but as I mentioned I have no use for it. I have a NOS 501 Prince still in the box I’ve never used so I don’t need another one. I use my Dirt Devil 103 when I have a need for a hand vac. I’m hoping it’s rarity and the collectibility of the Royal brand will make it pretty desirable.
 
Interesting variants

The Dirt Devil 501D is definitely a handsome unit. The Stark looks like it was designed to color coordinate with a Kirby Legend 2. Both are very cool. I love those metal Royal handhelds. I've got three of them. They outperform any other handheld I've ever used. I have a 1960s vintage model with the gray and red bag, a blue one from 1986, in the box with almost all its accessories, and a blue 1988 model that I paid a whopping $3 for at a thrift store. The only difference between it and the 1986 model is it has the little switch guard. They're built to last several lifetimes, and the only thing that will kill them off is a lack of replacement parts. Somebody really needs to start reproducing brush rolls and fans for them.
 
Different

This is actually a different vacuum. I sold the one last year on eBay to a Vacuumland member so when I found this one recently at a reasonable price I scooped it up. I did some minor reconditioning such as oiling the brush roll bearings and buffing the aluminum housing and it looks near new! The motor runs great so I didn’t do anything with that.
 
TylerHawkins84

Tyler,

The only thing that in my mind would make this 501D more attractive -- besides the fact it's the only Dirt Devil product to be built like a normal 501 Prince -- is if it had the earlier metal fan (1-157004-000).
