Dupray makes some of the best professional-grade canister steam cleaners we’ve seen in a while. Their Hill Injection and Tosca are some of the most high-end models, offering a ton of steaming-cleaning power per tank and versatility with a multitude of different cleaning tools. Between the Hill Injection and Tosca, which would suit your home or business better? Read our full review to find out.
You can tell that Dupray isn’t playing around by seeing how much force steam comes shooting out of the lance. The Hill Injection’s heavy-duty motor and boiling system delivers steam at a rate of up to 121 PSI. This will help in removing all hidden debris from corners, crevices, and any other hard-to-reach spot you can think of.
The Tosca shoots steam at 72.5 PSI—almost half of that of the Hill Injection but much higher than what you’d get out of traditional consumer-level canister steam cleaners. This much steam pressure should work well at killing surface bacteria and removing dirt and grease but won’t reach nearly as deep into tight spots as the Hill Injection.
The main purpose of steam cleaning is to eradicate bacteria and viruses by introducing them to super-heated steam. It doesn’t matter how much pressure is shot out of the nozzle or mop head, but when working on various surface types, the 121-PSI Hill Injection will have a better chance of forcing steam to enter every nook and cranny to draw dirt and grease out.
One of the most unique features of the Hill Injection is its dual-tank setup. One tank supplies water to the onboard boiler to produce dry steam at 345°F while the second tank slowly refills the first. The second tank can be refilled on the fly so you practically have an infinite amount of steam. You get roughly two to three minutes of steam before needing to wait 20 seconds for the quick-heating boiler to deliver more steam. If this doesn’t amaze you, we don’t know what will.
That isn’t to say that the Tosca’s 90-minute runtime from its humungous 1.05-gallon tank is bad. In fact, if you’re cleaning wide surfaces and don’t like pauses every couple of minutes, the Tosca heats the entire tank in eight minutes flat to give you uninterrupted 316° dry steam throughout the entire runtime. Now that’s amazing.
Choosing between “infinite” steam and 90 minutes of steam is a matter of personal preference. You’ll have to consider how much cleaning you plan on doing, roughly how long it’ll take, and how many gallons of water you’ll need before coming to a definitive conclusion. The safer option, we think, would be the Tosco’s 90-minute runtime with an eight-minute preheating period.
If you’d like to add a bit of suds and fragrance while cleaning, the Hill Injection gives you this option with a dedicated detergent tank. It injects a burst of your choice of soap into the outflow of steam to remove grimy stains permanently.
As for the Tosca, it relies solely on pure 316° dry steam to sanitize. No detergent tank available but no detergent tank necessary to eliminate 99.99% of surface bacteria.
Is a detergent tank absolutely vital in steam cleaning? Not at all—in fact, you can get by just fine without it with the Tosco. However, if you’d like to kill two birds with one stone and perfume your floors with a flowery fragrance, then the Hill Injection’s detergent tank will definitely come in handy.
Both the Hill Injection and Tosca use the latest control system. It looks pretty basic with only four buttons on the control pad, but it tells you everything you need to know. The display shows the current temperature inside of the boiler to give you an idea of what you can begin the steam-cleaning process.
Apart from the on/off button, there are three buttons that let you adjust how much pressure is shot out of the nozzle for safe, versatile cleaning. \
Dupray Hill Injection vs Tosca: Which Canister Steam Cleaner Should I Get?
As you can see, Dupray’s Hill Injection and Tosca are some of the most versatile steam cleaners out there, and we haven’t even gone into the 25-plus cleaning accessories that each comes with.
Overall, the Hill Injection is the more feature-packed of the two—enhanced steam pressure delivery, a dual-tank system for non-stop cleaning (except between pre-heating periods), and a detergent tank for added fragrance and cleaning power.
However, the question you should ask yourself when deciding between the two is “Can I live without these features?” If you can, then the Tosca is the more cost-effective alternative.
