One of the questions we get asked almost every week is:
“What’s the best grinder and vacuum combo to start an epoxy flooring business?”
The answer depends less on budget than most people think.
The biggest consideration is actually power.
Most residential garages only have 10 amp power, so buying a machine that needs more can mean constantly tripping breakers or searching for suitable circuits. That’s why many successful epoxy contractors deliberately choose a quality 10 amp setup when they’re mainly working on residential garages.
Alternatively, if you’re happy to invest a little more, bringing your own 15 amp generator opens the door to more powerful machines while eliminating power issues altogether.
Here are the four setups we’d recommend.
Redback 250 + Redback H22 Dust Extractor
If you’re starting out and want to keep costs sensible, this is easily our favourite entry-level setup.
The Redback 250 runs from a standard 10 amp outlet, making it perfect for residential garage work. It’s compact, reliable, easy to transport and incredibly simple to maintain. While the smaller grinding width means jobs take a little longer than larger machines, it’s still capable of producing excellent floor preparation.
Paired with the Redback H22 continuous bagging dust extractor, you’ve got everything needed to start completing professional epoxy floor preparation.
Best for: New businesses, garages, smaller residential jobs and contractors wanting the lowest entry cost.
Redback 500 + Redback H22 Dust Extractor
If your budget allows it, the Redback 500 is our favourite 10 amp professional setup.
You still get the convenience of plugging into standard residential power, but with a much more productive three-head planetary grinder that covers floors faster and leaves an excellent scratch pattern.
For contractors specialising in residential garages, this is one of the best balances of performance, reliability and simplicity available.
Best for: Contractors wanting maximum productivity while still working from standard 10 amp residential power.
If you’re planning to grow your business quickly, there’s another option we’d seriously consider.
Instead of relying on your customer’s power supply, bring your own.
The Westinghouse 8500E PRO 15 amp Generator is one of the best investments a new epoxy flooring business can make.
It gives you:
Rather than wondering what power is available at each job, you simply unload, start the generator and get to work.
Redback 450 + Westinghouse Generator + Redback H22 Dust Extractor
This is probably the setup we’d recommend to the majority of contractors wanting to build their business.
The Redback 450 offers a great balance of size, manoeuvrability and grinding performance, while the generator ensures you’re always supplying the machine with the power it was designed to use.
It’s noticeably more capable than a 10 amp machine without becoming oversized or difficult to transport.
Best for: Contractors wanting a serious long-term setup with excellent value for money.
Xingyi GX-510 + Westinghouse Generator + Redback H22 Dust Extractor
If you want one of the highest-performing single-phase grinders available, the GX-510 is an outstanding choice.
It delivers exceptional torque, heavy grinding pressure and serious productivity while still operating from a 15 amp single-phase power supply.
Combined with the Westinghouse generator, you’ve got a setup capable of tackling everything from residential garages through to demanding commercial preparation work, without needing three-phase power.
Best for: Contractors wanting premium single-phase performance and a setup they’ll be able to grow into for years.
Redback 250 + Redback H22
A proven, affordable way to get into the industry.
Redback 500 + Redback H22
Ideal if you’ll mainly be preparing residential garage floors using household power.
Redback 450 + Generator + Redback H22
Our pick for contractors wanting more performance without moving into three-phase equipment.
GX-510 + Generator + Redback H22
Maximum single-phase capability for businesses planning to take on larger or more demanding work.
