Choosing a portable refrigerant recovery machine for your service van often comes down to how much pressure protection you want, how quickly you need to move liquid refrigerant, and what you are willing to spend. Both of these 3/4 HP units sit in the refrigerant recovery vacuum service tools category and are designed to recover vapor and liquid refrigerant, and both list a 558 PSI high-pressure cutoff. The difference is in the details: one carries a higher listed price with explicit SAE connection sizes and a published liquid recovery rate, while the other carries a lower listed price with dual-stage filtration as a feature.
Quick verdict
Pick the VIV0HOME 3/4 HP Portable Refrigerant Recovery Machine if you want the lower listed price at USD 309.99 and prefer a spec list that includes dual-stage filtration and overcurrent protection. Pick the Uimoso Portable 3/4 HP Refrigerant Recovery Machine at USD 359.99 if you want a unit that spells out its 1/4" SAE inlet and exhaust interfaces and states a maximum liquid recovery rate of 4.85 lb/min.

Where each product wins
The Uimoso listing spells out the 1/4" SAE interface sizes for both air inlet and exhaust, so you know the connection standard before you hook up hoses. It also states a maximum liquid recovery rate of 4.85 lb/min, giving you a concrete number for planning recovery jobs. The high-pressure protection is listed as 38.6 bar / 558 PSI, matching the other unit's safety cutoff.
The VIV0HOME unit is listed at USD 309.99, which is USD 50.00 lower than the Uimoso unit's USD 359.99. It also calls out dual-stage filtration and overcurrent protection as features, and its listing describes an oil-less air-cooled piston compressor with a cooling fan. If you want the lower listed price and a machine that advertises internal protections, this is the direct alternative.
Product notes
Uimoso Portable 3/4 HP Refrigerant Recovery Machine for Vapor Liquid Refrigerant
Listed at USD 359.99, this portable 3/4 HP unit is the higher-priced option here, and it comes with specifications that are easy to act on. The air inlet and exhaust interfaces are both listed as 1/4" SAE, so you can see the connection standard before you buy. The high-pressure protection is stated as 38.6 bar / 558 PSI, and the maximum liquid recovery rate is listed at 4.85 lb/min. If your work involves moving liquid refrigerant and you want a machine that states its recovery rate and port sizes, this model gives you those details directly. The trade-off is simply the listed price: it costs USD 50.00 more than the VIV0HOME unit, and the description leans on the pressure gauge and dual-impurity filtration rather than a long list of compressor specs.
3/4 HP Portable Refrigerant Recovery Machine HVAC AC 558 PSI Oil-Less Compressor
At USD 309.99, this is the lower-priced machine in the comparison, and it leans on its compressor design and protective features. The listing describes an oil-less air-cooled piston compressor with a high-powered cooling fan, which is a useful detail for techs who want to avoid oil carryover. It also lists dual-stage filtration, overcurrent protection, and high-pressure protection with auto shut-off as features. The included dimensions are 15.7"(L) x 9.8"(W) x 14.0"(H), which gives you a sense of the footprint for mounting in a service vehicle. The trade-off for the USD 50.00 lower price is that this listing leads with compressor and protection details rather than SAE interface sizes or recovery-rate figures.
Final choice by use case
If your priority is the lower listed price plus a compressor that is advertised as oil-less, air-cooled, and piston-driven, and you like the sound of dual-stage filtration, go with the VIV0HOME 3/4 HP Portable Refrigerant Recovery Machine at USD 309.99. If you would rather have a machine that states its 1/4" SAE connection sizes and a maximum liquid recovery rate of 4.85 lb/min, and you are comfortable paying USD 359.99 for those specifics, the Uimoso Portable 3/4 HP Refrigerant Recovery Machine is the better fit. Both units list 558 PSI and are built around 3/4 HP recovery, so the final decision comes down to which spec sheet you trust for your workflow.
