When you're choosing a refrigerant recovery machine for AC work, the decision usually comes down to how much power you need versus how much you're willing to haul around. Both of these units sit at the same $359.99 price point, which makes the choice more about their design differences than the bottom line. A recovery machine is the bridge between the system you're servicing and the tank that stores the refrigerant, so the right choice shows up in smoother pulls and fewer setup headaches.
Quick verdict
The Uimoso is the simpler, more streamlined unit; the dual-cylinder is the more versatile unit.
Comparison table
| Feature | Uimoso 3/4 HP | 1 HP Dual Cylinder |
|---|---|---|
| Listed price | USD 359.99 | USD 359.99 |
| Motor | 3/4 HP | 1 HP, 1750 RPM |
| Recovery type | Vapor and liquid | Vapor and liquid |
| Weight | 29.5 lb | 32.6 lb |
| Filtration | Filter screen + dryer | Dual-stage filtration |
Where each product wins
The Uimoso wins on the specifics of liquid recovery. It lists a maximum liquid recovery rate of 4.85 lb/min, which gives you a planning number when pulling liquid from a system.
The dual-cylinder wins on flexibility. Its compressor setup is designed for demanding HVAC and automotive A/C recovery.
How to decide
To decide, look at your workday rather than the spec sheet. Consider how often you move the machine, how long recovery sessions run, and whether your calls vary widely. A shop that sees one refrigerant family will do fine with the Uimoso's straightforward setup. A mobile tech who bounces between car and residential calls will find the dual-cylinder's broader role more useful.
Product notes
Uimoso Portable 3/4 HP Refrigerant Recovery Machine for Vapor Liquid Refrigerant

The Uimoso Portable 3/4 HP Refrigerant Recovery Machine comes with a 558 PSI high-pressure cutoff at 38.6 bar, stopping the process if pressure gets too high. The precision pressure gauge provides continuous pressure readings while you work. The 1/4-inch SAE inlet and exhaust interfaces fit standard service hoses, and the operating range of 32-104°F covers most shop conditions. It includes a filter screen and dryer for dual-layer impurity protection, and the listed setup flow-connect, remove air, adjust knob, complete-makes the recovery sequence easy to follow. It's rated for R22 as well as refrigerant types III, IV, and V, matching older residential and light-commercial systems. The clear limitation is the 3/4 HP motor: this is the lower-horsepower machine in this pair, so heavy or continuous recovery work may push it harder than the 1 HP model.
Refrigerant Recovery Machine 1 HP Dual Cylinder AC HVAC Recycling Tool 1750RPM

The Refrigerant Recovery Machine 1 HP Dual Cylinder AC HVAC Recycling Tool 1750RPM is built around a twin-cylinder, oil-less, air-cooled piston compressor. It's compatible with R32, R134a, R22, R410A, R1234yf, and R454B, so it can move between residential HVAC, automotive A/C, and commercial chillers. The high-speed fan and larger condenser improve cooling efficiency during demanding recovery jobs, and the safety-first design adds another layer of protection. The listed dimensions of 16.5 by 9.8 by 13.6 inches give it a clear footprint on a service cart, and the included instruction manual helps you set up quickly. The trade-off is size and weight: at 32.6 lb, it's heavier than the Uimoso's 29.5 lb, which makes it less convenient on long carrying days.
Final choice by use case
If you prioritize high-pressure protection and a straightforward setup for classic refrigerant service, choose the Uimoso. Choose it for consistent, familiar jobs where you want the reassurance of a pressure cutoff. If your service days are mixed and you want a twin-cylinder tool that keeps you ready for different call types, choose the dual-cylinder. No matter which side you land on, the key is to match the machine to the service valve you encounter most.
