Daimer Steam Cleaner KleenJet Pro Plus 300CS Review

The Daimer KleenJet Pro Plus 330CS has to be one of the most unappealing steam cleaners on the market. But looks aside, how well does the steam cleaner perform? Read our review of the KleenJet 300CS to find out whether this electric-kettle-looking steam cleaner is right for your home.

75-PSI Steam Delivery Pressure at 310°

As the old adage goes: function over form. And while we bashed on the KleenJet 300CS’s aesthetics, we’d like to point out that this steam cleaner is actually a lot more powerful than its design and size might indicate.

This unit can deliver an astounding 75 PSI of pressure, so it can cut through heavy layers of grease, grime, mud, and anything you can think of in the blink of an eye. The KleenJet 300CS delivers about 20% more pressure than name-brand models.

Dual-Tank System

We bet you weren’t expecting this, were you? The only other noteworthy dual-tank steam cleaner we’ve heard of is the Dupray Hill Injection, and that one costs several times more than the KleenJet 300CS. With a dual-tank system, one tank is connected to the boiler element, while the other supplies water to the first tank.

In theory, this means infinite steam-cleaning. Refilling the boiler tank with fresh tap water means waiting for it to steam and build up pressure, but with this continuous cycle, the waiting times between pressure buildup are briefer, thereby allowing you to clean for much longer per session. The tanks measure 2 liters and 3 liters, with the smaller one being connected to the boiler element.

2-Minute Boiling and Pressure Buildup Times

Based on user reports, the KleenJet 300CS takes just two minutes to thoroughly heat up the water to 310 degrees and to build up 75 PSI of pressure. However, you only get about five to ten minutes of full-pressure steam flow, which isn’t that bad considering you can keep the cycle running continuously, thanks to the dual-tank design.

360° Casters

Something you won’t typically find in steam cleaners is caster wheels, but the KleenJet 300CS comes with four of them. While the casters can help you move around your home or garage to blow grease away with high-pressure steam, they aren’t lockable, so you won’t get a ton of stability from them. Try and keep the canister unit as close to you as possible—excessive tugging on the 10-foot-long pressure hose can cause the KleenJet 300CS to slip and slide or even tip over.

Stainless-Steel Housing and Boiler

You’ll be happy to know that many parts of the KleenJet 300CS are made with anti-corrosive stainless steel. This means you don’t necessarily have to use distilled water to keep the boiler element from deteriorating, though it definitely helps. Plus, the boiler is covered by a lifetime warranty, but it’s only valid if you use distilled water.

Comprehensive Accessory Kit

The KleenJet 300CS comes with a wide assortment of handy cleaning tools. You’ll get 30 detailing brushes for cleaning cracks and crevices, 10 microfiber cloths for removing grime from smooth surfaces, a 10-foot suction hose, a floorhead, a squeegee, extension wands, and more.

The KleenJet 300CS doesn’t have an onboard storage compartment, so make sure you place the cleaning accessories in a bag for safe keeping.
