How we scored them
Each steamer is scored out of 10 on performance, build, value, safety and warranty, with the weights published on our How We Pick page. Only the mecmic listing states a safety feature, a low-water alert; the rest state no safety listing, so the ranking comes mostly from the other four criteria.
| Product | Shop Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| mecmic SC702 Steam Cleaner | 9.7 | 32 | 22 | 21 | 4 | 3 |

| WSRYYCC LEST-C2 | 9.4 | 27 | 20 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
What the listings tell you
We read 5 steam cleaner listings. All 5 state wattage (1500 to 2500W) and heat-up time (10 to 20 seconds); 4 state a pressure figure (3 bar to 45 PSI); all 5 state tank size (1 to 1.6 L). Three state a warranty term and one states a safety feature; none states a safety certification. Two listings name engine cleaning outright.
Buying guide: best engine steam cleaner for the home garage
Power and heat
Stated power runs 1500 to 2500W and stated max steam 212 to 250°F. The mecmic pairs the top power with the top temperature; the Moongiantgo matches the power at a lower stated temperature. For baked-on engine grease, the listings point to hotter steam doing more of the work.
Pressure
Stated pressure runs 3 bar to 45 PSI where stated at all: 45 PSI for the mecmic, 43.5 PSI for the Granarbol, 3 bar for the Gautye and WSRYYCC. The Moongiantgo states no pressure figure, which is a gap in that listing, not a point against it.
Tank and runtime
Tanks run 1 to 1.6 L, with stated runtimes of 45 to 60-plus minutes where given. The mecmic and Granarbol both claim about an hour of steam per fill; the Moongiantgo, with the smallest tank, lets you add water at any time instead.
Reach
An engine bay rewards reach. The mecmic gives 16 ft of hose plus cord, the Gautye 13.2 ft, and the Granarbol a 78-inch cord with a 60-inch hose. The WSRYYCC has the least reach at 6.6 ft of hose plus a 4.92 ft cord, so plan on moving the unit.
Accessories
Accessory counts run 15 to 19 pieces on four of the five, with the Moongiantgo at 5. Brass brushes show up on the mecmic, Granarbol and WSRYYCC listings for scrubbing grease, and the Moongiantgo adds a small steel brush. Extension rods come with the mecmic, Granarbol and Gautye for reaching into the bay. The mecmic also packs silicone gloves and a refill funnel; the Granarbol adds an anti-clogging needle.
Engine bay cautions
Read the warnings in the listings. The Moongiantgo has no steam switch on the handle and its handle and hose heat up, so the listing recommends gloves. The mecmic sets steam level on the main unit, not the handle. Let the engine cool before you start, and keep steam away from open intakes.
What to check before you buy
Start with the tank, because it sets how long you steam before a refill. The mecmic and Granarbol both state 1.6 L tanks with about 60 minutes of steam per fill; the Gautye states a 1.69-quart tank for 45 minutes; the WSRYYCC states a 1.25 L tank with no runtime; and the Moongiantgo states a 1 L tank with no runtime but lets you add water at any time. A bigger tank means fewer interruptions on a filthy bay, while the Moongiantgo refill-anytime design suits quick jobs where you top up as you go. Heat-up times are short across the board: 10 seconds for the Granarbol, 15 for the mecmic, WSRYYCC and Gautye, and 20 for the Moongiantgo.
Next, weigh power against temperature and pressure. The mecmic and Moongiantgo state 2500W; the Gautye 1700W; the WSRYYCC and Granarbol 1500W. Stated steam temperature runs 212 to 250 degrees F: 250 for the mecmic, 221 for the WSRYYCC and Granarbol, 212 for the Moongiantgo and Gautye. Stated pressure runs 45 PSI for the mecmic, 43.5 PSI for the Granarbol, and 3 bar for the Gautye and WSRYYCC, while the Moongiantgo states no pressure figure. All five are corded electric, with the mecmic at 120V and the Moongiantgo and Gautye at 110V. Hotter steam and higher pressure do more of the grease work, so match those figures to how baked-on your engine grime is.
Finally, check the controls and the box contents. Steam levels are adjustable on four of the five: 6 levels on the mecmic and WSRYYCC, 3 on the Granarbol and Gautye, with the Gautye adjusting on the handle, the mecmic on the main unit, and the Moongiantgo offering no handle control at all. Accessory counts run 15 to 19 pieces on four listings, with the Moongiantgo at 5; brass brushes show up on the mecmic, Granarbol and WSRYYCC for scrubbing, and the Moongiantgo adds a small steel brush. Read the warnings too: the Moongiantgo listing says the handle and hose heat up and recommends gloves, and the mecmic care instructions say to empty leftover water after use. On warranty, the mecmic states a full 3 years with lifetime support, the Moongiantgo 1 year with free parts replacement, and the Gautye one year of after-sales service, while the WSRYYCC and Granarbol state no warranty term.
Keep electric pressure washers on a GFCI outlet, never point the wand at people or pets, wear eye protection with polishers and chemicals, and read the label before mixing any cleaning products. Read our Safety Disclaimer.
Garage Fit Check
- All five are corded electric; check outlet distance against the stated reach before you buy.
- The mecmic refills with no cooling wait; the Moongiantgo adds water at any time.
- Handle controls differ: the Gautye adjusts steam on the handle, the mecmic on the main unit, the Moongiantgo not at all.
- Accessory counts run 15 to 19 pieces, except the Moongiantgo with 5; check the box on arrival.
- Empty leftover water after use, per the mecmic care instructions, to slow mineral buildup.
Frequently Asked Questions
Can I use a steam cleaner on my engine?
Two listings name engine cleaning outright: the Moongiantgo title and the Granarbol listing. The others list car detailing among their uses. Let the engine cool first and follow the warnings in the listing you buy.
What pressure do I need for engine grease?
The listings state 45 PSI (mecmic), 43.5 PSI (Granarbol) and 3 bar (Gautye, WSRYYCC); the Moongiantgo states no pressure. Hotter steam and more pressure are what the listings offer for grease, not a number we set.
How long does the steam last per fill?
Where stated: 60 minutes for the mecmic, over 60 for the Granarbol, 45 for the Gautye. The WSRYYCC and Moongiantgo state no runtime; the Moongiantgo lets you add water at any time.
Do any of these steam cleaners have a warranty?
Three do. The mecmic states a full 3-year warranty with lifetime support, the Moongiantgo 1 year with free parts replacement, and the Gautye one year of after-sales service. The Granarbol and WSRYYCC state no warranty term.
Steam cleaner or pressure washer for the engine bay?
Steam cleans with heat and little water; a pressure washer cleans with force and a lot of water. See our steam cleaner vs pressure washer for cars comparison.
