ARRR uses the equihash mining algorithm and can be mined using a variety of ASIC equihash-compatible hardware as well as a variety of GPUs. Although ASIC is highly recommended due to the high level of hashpower needed. There are a few brands that offer equihash mining software. You will need to do your own research before investing in a brand or distributor. 

As ASIC hardware tends to be noisy and produce heat, there are also hosting companies available. However you need to be vigilant with the terms as the prices fluctuate and so does any mining profit.
