The Gtech Multi Mk2 has a washable filter that needs to be cleaned on a monthly basis. Here’s how to clean the filter and maintain your vacuum’s suction power.
The Gtech Multi Mk2 has a basic foam filter. Over time, dirt and other debris builds up on the filter, which reduces suction power.
Fortunately, cleaning the Gtech’s filter is a straightforward process. You just need to remove the filter, rinse it under a cold tap, then allow it to dry. We’ll show you exactly how to clean it in this article.

Step 1: Remove the Multi Mk2’s Bin
The Gtech Multi Mk2’s filter is located inside the main cylinder. To access it, you first need to remove the bin.
Unlike many vacuums, there isn’t a button to remove the bin. Instead, you just pull it away from the vacuum’s body.
We’ve found the bin can sometimes be a bit stiff – especially if you have a new Gtech – so you might need to wiggle it a bit.
Step 2: Pull Out The Filter
Once the bin has been removed, you’ll be able to access the “Filter” knob. Pull this to remove the filter from the bin.
Check inside the housing. If there’s any loose dirt, this is a good time to tip it into a bin.
Step 3: Rinse The Filter With Cold Water
Hold the filter and tap off loose dirt into a bin. You don’t need to whack the filter – a gentle tap is enough!
If there is still visible dirt on the filter after tapping it off, you’ll need to clean it:
- Rinse the filter under a cold tap until the water runs clear. Do not use hot water or any detergent.
- Gently squeeze out excess water (not too hard though!)
- Allow the filter time to dry completely before replacing it in the bin. In most cases, we recommended leaving the filter to air dry for around 24 hours.
It’s vital not to put a wet (or even damp) filter back into the Gtech Multi Mk2. Doing so could allow water to reach the motor, which can cause serious damage (and risk an electric shock).
A damp filter is also the perfect environment for mould and milder to grow.
Step 4: Re-Insert The Filter And Replace the Bin
Once the filter has fully dried, re-insert it into the bin and reattach the bin to the vacuum body.
Your Gtech Multi Mk2 is now ready to use!
Tip: You should never re-insert the bin before replacing the filter. Running the Gtech Multi Mk2 without a filter could cause permanent damage to the vacuum cleaner’s motor.
What Should I Do If My Gtech Has Poor Suction?
Low suction is nearly always caused by a blocked filter or an overfilled bin. So, these are the issues to check for first.
However, if cleaning the filter hasn’t fixed a low-suction problem, there is probably a blockage elsewhere in the vacuum. The most likely culprits are the main tube, outlet from the bin (you’ll need to remove the bin to access this), and inside the tools.
It’s also possible that hair has become tangled around the Power Brush brushroll. To fix this issue, remove the brush and carefully cut away hair.
Gtech has made it easy to clean the Multi Mk2’s filter. Here’s a quick recap of the process:
- Remove the bin and pull out the filter.
- Tap off excess dirt into a bin (you may also want to tip loose dirt inside the filter housing into a bin)
- Rinse the filter in cold water from a tap without a detergent. If possible, rinse until the water runs clear.
- Gently squeeze off excess water, then allow the filter enough time to dry fully.
- Reinsert the filter into the bin and reattach the bin to the vacuum.
