How to Switch Cleaning Modes?

This machine offers two cleaning modes: Hot Water Mode Press the "Water" button on the handle once. Preparation Time: 15-25 seconds for hot water. Steam Mode Quickly press the "Steam" button on the handle twice. Preparation Time: 30-35 seconds for steam. Note: During steam preparation, a small amount of water may discharge—this is normal. For optimal performance, wait until the mode is fully prepared before starting cleaning.

Why is the surface still damp after cleaning?

(1) When operating the machine, there's no need to hold down the water spray button continuously. Simply wet the stained area thoroughly, wait for the stain to dissolve, and then scrub. (2) The upholstery cleaner works similarly to a washing machine—cleaned items will naturally remain wet. First, spray water and scrub, then keep the brush head upright and press down to suction, much like blow-drying hair. The longer you suction, the drier the surface becomes.

How to Handle Machine Leakage?

(1) Clean Water Tank Leakage: Lift the water tank separately to check if it continues leaking. If leaking: Replace the tank. If not leaking: Normal operation. (2) Dirty Water Tank Leakage: Check if internal components are properly installed. If still leaking after correct installation: Replace the dirty water tank. (3) Machine Base Leakage: Check for foam overflow. If excessive cleaning solution prevents the float from rising: Empty the dirty water tank. Rinse residual cleaning solution from the clean water tank. Restart the machine and check for water stains at the base. If leakage persists: Internal component failure—contact after-sales service for repair. Note: Dilute cleaning solution at a 1:30 ratio. Over-concentration may cause overflow, affecting performance and cleaning results.

How to do if the machine stops work?

First, make sure the power connection is secure. Then, check for any blockages inside the machine. If everything looks fine, try resetting the machine. And if the issue persists, just reach out to our support team for further assistance.

What to do if the machine has no suction/suction weakens?

(1) Check if the dust-cleaning mechanism is jammed by debris or hair. If so, clean it thoroughly and manually slide the mechanism back and forth at least 3 times before reuse. (2) If the issue persists, the dustbin may be faulty - try replacing it. Note: Always empty the dustbin promptly when full during use to prevent clogging and maintain optimal performance. Excessive dirt accumulation may affect functionality.

Which Materials Are Suitable for Cleaning with an Upholstery Cleaner?

Generally, any material that is water-washable can be cleaned with an upholstery cleaner. Note: For delicate or expensive materials (such as wool carpets, leather sofas, or latex mattresses), it is recommended to test the cleaner on a small, hidden area first. If no issues occur, proceed with full-scale cleaning.
