Overview
Not a handheld steamer, the SF-370 is a canister unit with a corded base, a hose and a large set of tools. Water heats in the tank and steam is released when the trigger is pressed.
The kit covers floors with a mop head and microfiber pads, and counters, windows and corners with brushes and a squeegee. A large tank gives a long run time. The unit is built for US voltage and weighs enough to carry with its handle.
Who it's for
Homes with sealed floors and lots of surfaces to refresh will use the mop head and the tool kit. Travelers, apartment users with tight storage and anyone outside the US should look at a smaller or compatible model.
Pros and cons
- Many accessories included
- Long run time per tank
- Mop attachment for sealed floors
- Trigger and locking switch
- Built for US voltage only
- Sized for a closet, not a drawer
- Hand wipe cleaning only
Performance notes
A boiler heats ordinary water into pressurized steam, and the trigger releases it on demand. Steam loosens dirt and the attachments aim it: the jet nozzle for cracks, the mop head for floors. Tank size and heat time set how long you can clean per fill.
