Maintaining Your Sirena System

Maintaining Your Sirena System

Sirena Total Home Cleaning System is a water vacuum cleaner which means it doesn’t require replaceable bags to collect dust and dirt. Instead, a basin filled with clear water is used to capture everything that is sucked in. Relying on water-based filtration technology makes Sirena one of the most efficient and reliable vacuum cleaners on the market. However, even the best and most efficient vacuums will eventually begin to lose their cleaning ability if not maintained properly. Unlike traditional vacuum cleaners which only require you to periodically change vacuum bags caring for your Sirena System is a slightly more complex process. But don’t worry, it’s not rocket science!

Sirena System Maintenance

1) Cleaning the water basin after each use

Discarding the dirty water after use is, obviously, the most important step. But don’t forget to wash the water basin afterwards to remove the residual dirt and then dry the basin out. This will prevent mold and mildew build-up inside the basin which could lead to unwanted smells and reduced cleaning ability.

2) Drying out the wet and dry hose after picking up liquid spills

Sirena is among the very few vacuum cleaners that allow you to safely pick up non-flammable liquid spills. It works wondrously when removing wet stains from carpets as well. Just pour some clear water on top of the spill, agitate it into the carpet, and then use Sirena to pull out the liquid. Now our problem is the hose itself is wet on the inside and it would be unwise to leave it to dry on its own. For the same reasons as drying out the water basin it’s important to force-dry the hose immediately after picking up liquids. The best way to do that is to connect the working end of the hose to the exhaust and let the air circulate for about 30 seconds.

3) Cleaning the separator every 3-5 uses

Have you ever wondered what kind of magic prevents the water in the basin from entering the Sirena motor? Meet the separator. This simple yet potent piece of plastic spins at mind-boggling 19,527 RPM (revolutions per minute) and throws the water touching it outward, away from the motor and back into the basin. Because it is in constant contact with the contents of the water basin it is very important to clean the separator after every 3-5 uses to keep your Sirena running optimally. Use the wrench/brush tool (stored on-board) to remove the retaining nut and clean the separator.

4) Washing and replacing the HEPA filter

The only non-water filter inside the Sirena System, HEPA (High Efficiency Particulate Absorption) filter is the last line of defense against the contaminants in the air. While 99.9% of everything that flies in your air or hides in your carpets will be successfully captured in the water, there is always that 0.01% that manages to slip past the water trap. Some super-fine non-water-soluble particles will be captured by the HEPA filter which is located right before the exhaust. It’s removable and washable which means you only need to replace it once every 12-18 months. However, we recommend washing the filter at least once every 4 months to ensure it retains its amazing filtering abilities.

5) Cleaning the Power Nozzle

One of the most versatile Sirena tools is the Power Nozzle. Featuring 3 height adjustments and multi-directional cleaning head it’s a great tool to use on carpets of all kinds. A rotating beater brush agitates the carpets and brings the embedded dust and dirt to the surface where it’s sucked into the vacuum. From time to time the dirt and hair build-up may clog the opening and prevent the beater brush from operating effectively. This may lead to a reduction in cleaning ability, additional strain on the belt, and even power nozzle overheating. Our friends at FIX IT Home Improvement Channel made an excellent video on how to clean the power nozzle in under a minute.
