H2O e3 eActivator Cleaning System

Product number: 46376

Voted as a 2021 Product of the Year Finalist by the Largest Consumer Survey of Product Innovation.

Keeping our homes and families safe from viruses, germs and bacteria is a hot topic for most of us right now, so imagine being able to create your own super-efficient sanitising solution whenever you need it. In just 10 minutes, the H2O eActivator Cleaning System turns water and ordinary table salt into a powerful home cleaning fluid that cuts through grease and grime, kills germs, eliminates odours and – instead of costing you a fortune to add to your regular weekly shop, costs just pennies to make at home. Even better, it uses the same bottle every time too.

What you get:

  • S-mart water eActivator bottle – just fill with water, add salt and plug in to create S-mart water sanitising fluid whenever you want to clean and sanitise your home – and if you want to kill off viruses like the flu bug, just add a spoonful (2.1ml) of white vinegar to the mixture. S-mart water will gradually lose its effectiveness over time (7-14 days) so it’s best to make a fresh bottleful once a week or so.
  • eSprayer trigger nozzle – attaches to the screwtop of the eActivator so it can be used for cleaning hard and soft surfaces all around your home.
  • Mains power adaptor.
  • Measuring spoon – to ensure you add just the right amount of table salt or vinegar each time.

Effective cleaner and sanitiser

Your eActivator electrolyses tap water and table salt, using low-voltage electricity to change the molecular structure and create sodium hydroxide (a powerful degreaser) and hypochlorous acid (a sanitiser). Together, these cut through grease and grime, kill germs and eliminate odours – and this super-cheap, multi-purpose household cleaner is not harmful to your family or your pets.

Where can I use it?

Hard surfaces – Ideal for hard surfaces of all types, from door handles, kitchen counters and chopping boards, to floors, mirrors and windows, spray S-mart water directly onto surfaces and mop or wipe away the dirt.

Deodoriser – sprayed into shoes, trainers or kitchen bins, S-mart water can help kill off nasty odours too. It may leave a ‘dusty’ residue on trainers and shoes once it’s dry, but this can just be brushed away.

Complete home cleaner – S-mart water can be used in any room around your home – kitchen, bathroom, hallway, conservatory – or even outdoors.

Economical and eco-friendly

You never need to throw away this cleaning bottle, just refill it, charge it and get cleaning – you’ll cut down on the number of chemicals you buy and reduce your recycling burden too. The H2O eActivator makes a liquid sanitiser that’s effective for days, never weighs down your shopping bags, and takes up hardly any room in your cupboards.

Please note: you should avoid spraying S-mart water onto metal surfaces that are sensitive to salt corrosion, such as aluminium or chrome. Do not use it on unsealed wood floors, carpet, leather, clothing, or any other fabric or soft materials as there is a strong risk of discolouration or fading.

450ml. 26cm H. Flex 65cm. 5W.

"Fantastic Product"

star star star star star

I must admit I was skeptical at first, not really understanding the science but it works a treat and when I think about it back when my Grandmother was alive they would not have had the chemicals that we use today and probably would have used salt and water to clean their surfaces. It is expensive but I think it will pay for itself in the long term.

"Great idea but spray bottle not great!"

star star star star star_border

Tried this as a safer cleaning system eliminating unpleasant chemicals. The first one didn't spray at all & Lakeland replaced it. The second leaks at the base. I would have expected a better quality unit. By amalgamating the top and bottom of the two I hopefully have one which works. Lakeland's customer service was as excellent as ever and there would have been no difficulty obtaining a refund but I have persevered as I feel the idea is terrific and it does seem like a great innovation in cleaning safely and very effectively, especially in these times of pandemic.

support_agent A note from the team

This was expensive , but I love the science behind it and read about it's use in industry. So bought it a few months ago. I bought it mostly to sterise surfaces but found its a excellent cleaner all round the home even cooker top. It has a slight bleach smell. This is the future of household cleaning. It will pay for itself .only a bit miffed it's £ 20 cheaper now.

"A revolution! My mind is blown!!"

star star star star star

This device is fantastic. It cuts through grease no problem, cleans with ease and leaves a fresh smell. I really can't get my head around how the technology and the chemistry makes salt and water do this! If someone had asked me if I would believe it, I would have said no chance. It will cut down not only the expensive of my cleaner product obsession but will make me feel a heap better about all the wasted cleaner bottles I will never use again, and help save the environment a bit. Plus it kills 99% germs and bacteria at the same time! Its honestly the best invention ever. Its brilliant!

"I use a lot of it!"

star star star star star

I did a lot of googling to try to confirm the effectiveness of the anti viral properties of this. Now I use it most of the time, I like the fact it separates out again so I am not filling the environment with chemicals. I can use it generously on most things. My only gripe is that it could do with a surfactant as it tends to bead.
