RUNS THREE-PHASE MOTORS FROM SINGLE-PHASE POWER AT 2/3 RATED HP*
*Refers to wye-wound motors; delta-wound motors will run at 50% rated HP. Delta-wound motors are very rare in the USA, occasionally being found on some imported equipment, and are particularly found on German and Italian machines.Phase-A-Matic™ Static Phase Converters have been developed, tested, and thoroughly proven over a 46 year period demonstrating exceptionally high reliability and long life. These converters are the workhorse of many commercial uses and multitudes of home shop machines.
LIFE EXPECTANCY: The Static Converter has been in use for approximately 52 years and has already proven itself to be extremely reliable when properly applied. Phase-A-Matic™ was recently able to purchase back the first one that was ever sold, and it is still working fine. It is reasonable to expect the converter to be in good working condition and service for 20 or 30 years or more. We continue to hear back from customers who have them still running their equipment faithfully after 20 years and more.
Uses include: Lathes, Mills, Grinders, Drills, Saws, Metalworking and Woodworking Equipment, Printing Equipment, Sewing Machines, Garbage Disposals, Food Processing Equipment, Meat Grinders, Food Mixers and Blenders, Conveyer Belts, and numerous other uses.
METHOD #1
Using the Phase-A-Matic™ Static Converter only will produce approximately 2/3 normal HP.* This method is inexpensive, the most popular, provides excellent results on most machines tools and numerous other uses. Motor speed is not changed. Most two-speed motors, power feeds, coolant pumps, etc., will operate normally. Motor will instant reverse. There is nothing to change. All switch gear will work normally.
*Refers to wye-wound motors; delta-wound motors will run at 50% rated HP. Delta-wound motors are very rare in the USA, occasionally being found on some imported equipment, and are particularly found on German and Italian machines.
METHOD #2
FOR FULL OR CLOSE TO FULL HP
~~ Configure as a rotary converter using Phase-A-Matic™ static unit ~~
Full or close to full HP can usually be obtained by running a three-phase motor and Phase-A-Matic™ Static Converter combination as shown on the Installation Instructions. When running unloaded, the windings of the motor function as a rotary transformer or generator while consuming very little extra power. The Idler Motor needs to be at least 50% larger than the largest motor that you want to run to accommodate the higher starting current. A good quality 3600 RPM, three phase wye-wound, 220V motor is the best choice. 1800 RPM motors can be used on applications not heavily loaded. Used three-phase motors are inexpensive and readily available.
When using this method, it is possible to run multiple machines as long as the idler motor is large enough to handle the largest load it would ever have at any one time. For instant reversing of the load motor, as in rigid tapping, the idler motor must be a minimum of twice the HP rating of the load motor, and perhaps more.
The Static Converter is sized to the HP of the idler motor, not the load motor(s).

Pretty great set for the price! HOWEVER, the rotary brush doesn't fit.
This is a nice little set of replacement items for your C10 for the price. It's always good to have extra bags, brushes, and filters...especially if you live with multiple animals on a very dusty farm like I do! The filters, bags, and front brushes fit perfectly in Tilly (my Eufy C10), however the main vacuum rotary brush was too short and did not fit. You can see from my photos, I've compared it to the original brush for the vacuum and it is too short and the end fittings do not match up either. This is the only part of the set that didn't work for my vacuum. The rest of the set is acceptable quality for the price. The reason I gave this set 4 stars instead of 3 is because I actually PREFER these front brushes over the originals because they WORK BETTER than the originals. If the issue with the fit of the rotary brush is addressed, this would be a 5 star set of C10 replacement parts.

Perfect combo replacement parts.
These replacement parts fit my Eufy C10 without any issues and were easy to install. Everything snapped into place just like the original components, and I did not need any tools or adjustments. It was a quick refresh that had the vacuum back to normal cleaning right away.
The main brush feels sturdy and does a good job picking up debris without getting tangled too quickly. The side brushes spin smoothly and reach edges and corners well. I also noticed that the filters fit securely and do not feel flimsy, which helps maintain suction and keeps fine dust contained. The dust bags are well made and install cleanly without gaps or leaks.
After replacing the parts, the vacuum runs quietly and cleans more efficiently, especially on hard floors and along baseboards. It feels like routine maintenance that actually makes a noticeable difference in performance rather than just a cosmetic swap.
Overall, this is a solid replacement kit that matches the original parts well. It is a convenient way to keep the robot vacuum running smoothly and is a good option if you want reliable performance without hassle.

Practically 1:1
This kit is pretty much the same quality you would expect if you ordered directly from Eufy, excepting the HEPA filters which are *slightly* larger, and kind of weak compared to the originals. Aside from the filters, though, these are all very high quality parts, and practically indistinguishable from anything you would get directly from the manufacturer.
I went all in with these and replaced all of the original parts with these in one go a few weeks ago and the C10 is performing just as well as it did with the original parts. The size is spot on, the roller brush has the exact same functionality (unlike the ones I had ordered in the past for my 15C which scuffed up the unit), and the dust bags are functioning just like the originals, as well. I stuck the included cleaning brush off to the side in the base, and I use it to clean the unit every time I clean the HEPA filter.
Honestly, you really can't beat this value, these are great quality, and so much cheaper than the original parts.

Great Value Replacement Kit for Eufy C10
I recently picked up the Eufy C10 robot vacuum and absolutely love it, so I was excited to find this accessory kit. This is a much more economical way to stock up on all the wear-and-tear parts your robot needs. Everything fits perfectly, the quality feels solid, and it includes all the essentials—main brush, side brushes, filters, and disposable dust bags. Having these on hand makes maintenance easy and keeps the vacuum running at peak performance. If you own a Eufy C10, this kit is a no-brainer.
Pros
• Excellent value compared to buying parts individually
• Includes all common replacement items
• Fits the Eufy C10 perfectly
• Good build quality on brushes, filters, and bags
• Easy snap-in replacement with no tools required
Cons
• None so far
Verdict
A smart and affordable way to maintain your Eufy C10. Everything you need in one kit, good quality, and great peace of mind. Highly recommended.
