## Customer Reviews

### ⭐⭐⭐⭐⭐ Works exactly as described.
*by ~***~ on July 1, 2024*

Works exactly as advertised. I have the sensor attached to the power cable that runs from the CNC controller to the spindle on my Shapeoko 5 Pro 4'x4' router. A couple seconds after the CAM software sends the "turn on spindle" command, the unit activates and powers up my dust collection system. The delay is nice because it means I don't have two high power draw devices powering up simultaneously even though the router and dust collection are on separate circuits. Once the job finishes, the dust collection is turned off. It just plain works.

### ⭐⭐⭐⭐⭐ Good product, Very Exciting Ecosystem (and this is the 'core' piece)
*by N***G on June 21, 2016*

There are a few ways to go if you decide you want to add a remote start system to tools in your shop. The first place most people start is with dust collection. There's an ultra cheap method that (knowing some electrical strain would occur) I didn't feel comfortable with, even at 1/4 of the price. And then there's a "tried and tested" product that is certainly a good way to go, and you'll likely find a lot of the forums will make this suggestion, as well.After some further digging, I decided to choose this product -- primarily because I liked the idea of investing in an expandable system. For a very small premium, this product functions exactly the same as the tried and true product, but iVac, unlike the other company, is continually dumping profit into R&D -- developing extensions off of this unit that allow you to truly automate your shop. Be it opening a blast gate and automatically starting the DC, power sensors that sit on a tool's power cord and automatically start the DC when a current is detected, or, a simple on/off remote accessory.The accessories are far from cheap (and you unfortunately have to buy the remote separately), but the potential of the ecosystem is very high, and the manufacturing quality of these units is higher than the competition.The easiest way to decide if the iVac is the correct choice for you is to ask yourself "Will I regret buying a single, un-expandable automation path? Or would I rather pay a small premium and give myself options down the road?".

### ⭐ Junk
*by C***D on April 24, 2025*

What a piece of junkIt works when it wants toWish I just put the vacuum on a switch for the amount of times I have to unplug the dam thing
