FAQs

General questions:

What is MultiFLEX technoWhat is MultiFLEX technology?

MultiFLEX Technology allows the wand to bend, providing 2 main benefits. The bent wand allows for easy cleaning under furniture and allows the vacuum to fold over for freestanding, compact storage.

How do I use MultiFLEX technology?

Locate the button on the backside of the wand. For easier under furniture cleaning, use the button to bend the wand. Turn the power on and start vacuuming. For storage, turn the vacuum off and then use the button to gently fold the handheld vacuum forward toward the floor nozzle.

NOTE : Not all models are equipped with MultiFlex technology.

How do I attach accessories to the vacuum?

There are two ways to clean with the accessories.

Either separate the handheld portion from the rest of the vacuum by pressing the “Handvac Release” button or keep the wand connected to the handheld and remove the floor nozzle by pressing the “Wand Release” button. Choose the desired cleaning accessory and slide it onto the end of the handheld vacuum or the end of the wand. You will hear a click when it is appropriately attached.

How long does it take to fully charge the battery?

It takes approximately 3 hours to reach a full charge.

What is the runtime of the battery on a full charge?

The initial charge on the pack (out of the box) is approximately 30%. We recommend fully charging the battery before initial use.

These runtimes are based on 100% capacity:
– IZ440H Series handheld vacuum only mode: approximately 50 minutes
– IZ460H Series handheld vacuum only mode: approximately 60 minutes
– Handheld vacuum only with BOOST mode: approximately 10 minutes
– Bare Floor mode: approximately 34 minutes
– Bare Floor mode with BOOST: approximately 10 minutes
– Carpet mode: approximately 23 minutes
– Carpet mode with BOOST: approximately 10 minutes

Like all lithium-ion products, the battery will naturally decrease in capacity over time.

How do I store the vacuum?

Store your vacuum securely and out of reach of children or pets.

If your vacuum is equipped with a MultiFLEX wand, you can store it in a compact, upright position.

– Press the unlock latch on the back of the wand, then fold the handheld vacuum forward, toward the floor nozzle.
– Another option is to simply place the vacuum flat on the floor. The rubber pads on the base of the handheld vacuum will prevent scratching.

General questions about using the vacuum:

How do I remove the handle to clean above floors?

To clean above-floor areas with the handheld vacuum, press the wand release button on the front of the wand, then gently lift off the handheld vacuum.

How do I remove the handle with extension wand to clean above floors?

For more cleaning reach, leave the handheld vacuum on the wand, and detach the wand from the floor nozzle. Press the nozzle release button on the bottom of the wand, then gently pull up on the handheld vacuum to remove the wand.

How do I turn the vacuum off?

To turn the vacuum off, slide switch to the bottom to turn off power.

General questions about maintenance:

How do I clean the filters and how often?

Filters may need to be cleaned if the vacuum stops picking up dirt, if airflow is restricted, or if you notice decreased or no suction. For optimal performance, clean filters regularly. Between cleanings, lightly tap filters over a trash receptacle to remove dust and debris as needed.

Rinse the pre-motor foam and felt filters every month, or as needed.

First, remove the dust cup to access the pre-motor filters. Press the release button on the handheld vacuum, then pull the dust cup down and away.
Remove the foam and felt filters using the tab provided.
Rinse both filters with water only.
Allow filters to air-dry completely (at least 24 hours) before reinstalling.
Once dry, install the foam filter first, followed by the felt filter.
Reinstall the dust cup.

Rinse the post-motor HEPA filter every 12 months, or as needed.

Remove the dust cup by pressing the release button on the handheld vacuum, then pulling the dust cup down and away.
The post-motor filter is attached to a plastic frame inside the handheld vacuum. Press the tabs and pull the filter off the frame.
Rinse the post-motor filter with water only.
Allow filter to air-dry completely (at least 24 hours) before reinstalling.
Once dry, reinstall the post-motor filter.
Reinstall the dust cup.

How do I empty the dust cup and how often?

First, turn the power off.

Detach the handheld vacuum from the wand by pressing the wand release button.
Position the dust cup over a trash receptacle, then open the bottom dust cup door by sliding the CleanTouch Dirt Ejector slider forward.
Tap gently to empty contents.
Wipe the interior of the dust cup clean if needed.
Close the dust cup door, pressing it until it clicks into place.

For optimal performance, the dust cup should be emptied each time you vacuum and when the dust cup appears full or debris reaches the “MAX FILL” line.

Using a coin, turn locks counterclockwise to open, then lift off cover to access the self-cleaning brushroll.
