Overview:

With performance engines pushing redlines up higher and higher, alternators are being forced beyond their design. Holley's premium alternators are specially designed to tolerate 30% higher RPMs than conventional alternators and made in the USA. If you drag race, auto-cross, or just hot-rod your ride, know this alternator won't fly apart on you. Inside the attractive Holley housing is cutting edge technology. Every component was developed to produce cleaner, more efficient output compared to conventional alternators. Efficiency means you get more from a compact package. GM recently adopted this technology for the 2014 and later Corvettes. The attention to cosmetic detail on these units is above and beyond what you would expect too. The entire outside housing has been sculpted for a smooth silhouette that hides the ugly details we think of as alternators. The housings are smoothed to make polishing clean (no buffer cut marks trying to get in tight corners). Even the rear cover is aluminum so you lose that black plastic on your polished alternator. Available in Natural, black, and polished finishes. For that finishing touch, black pulley covers are available to give a simple but refined look on the 197-302 and 197-303. The 197-304 polished alternator already includes a polished cover. These powerhouses fit ALL Holley accessory brackets, as well as 4th generation F-body, most 1998 thru 2004 GM trucks, and many other applications.

  • Works with ALL Holley accessory brackets
  • 150 Amp Output

LOVE ❤️
I’ve only had this for a few days but I am in LOVE with it and maybe a little obsessed. Even my husband commented on how clean our floors were after the first use. The mapping feature works very well; better than my previous robo vac. I love that it takes the everyday maintenance out of the equation by cleaning/drying the mop heads itself. I wish the instruction manual had more info in it, as well as what some of the features on the app entail, but I’m sure google can provide that info. I’m very pleased with this product.

If it doesn't connect to Wi-Fi do a hard reboot and start download again.
I have had this for 2 days. I could not connect this to my WiFi. I wanted to do a hard reboot but the small pamphlet doesn't explain how, the pamphlet is basically useless. I looked on line and performed it then set it back up. It now works really well as a vacuum. I haven't tried the floor washing yet but the vacuum portion is really very good cleans better than my other older two well known vacuums combined. The other two older robot vacuums I never needed to program to have them vacuum but this one you need too. It won't work without it. It wasn't had to program either.

The mop feature works really well on floor that are bare, it does not do a very good job on vaccuming area rugs and it can not get on top of thicker rugs to vaccum. IF you have bare floor or area rugs that can be easily removed it is great. I love the mop wash mode.

I'm in love with this thing
A few tweaks in the app and it cleans like a dream . I don't have pets but I have kids and this takes a load off my shoulders , It's pretty quiet , and the mops the whole floor , the battery life is pretty good for multitasking , it lasts all 800 sq ft of the bottom of the house

Perfect fit, quick fix & vacuum works like new
Number of Items: 1, Style: X10 Pro Omni Accessories Kit, Number of Items: 1, Style: X10 Pro Omni Accessories Kit
The Eufy RoboVac X10 Pro Omni replacement accessories kit fit perfectly-filters, brushes, and mop pads all snapped in without tools. Instructions were clear, and the vacuum’s back to full suction and mop performance. Good quality materials, fair price, quick fix.
