Price on writing: £399 | Buy now from eufy

The eufy S1 Pro has a sleek, premium design, but its generous capacity means it takes up a fair amount of kitchen worktop space.

How we tested the eufy S1 Pro Bottle Washer and Steriliser

Holly tested the eufy S1 Pro for four weeks with her one-year-old son, using it around once a day to wash bottles and breast pump parts as part of her family’s usual feeding routine.

During testing, she assessed its cleaning and drying performance, how easy it was to set up and operate, and how well it fitted into everyday family life. She also considered its build quality, capacity, maintenance requirements and value for money, drawing on her experience of other bottle washers.

Once testing was complete, Holly scored the eufy S1 Pro on performance, quality and durability, ease of use, value for money, size and capacity, speed, hygiene and cleaning, and safety features.

What’s in the box?

Holly found everything well packaged, easy to unpack and securely fitted in the box.

The eufy S1 Pro comes with:

• Main bottle washer unit

• Water softener

• Drainage hose

• Power cord

• 60 detergent tablets

• Quick start guide and user guide

Does it include any extras?

The eufy S1 Pro has app control, allowing you to monitor progress, schedule washes and customise cycles remotely. The app also shows how many water softener cycles you have left, helping you keep track of when it needs replacing.

Holly said, “We didn’t really see the need for the delayed start functionality or the app, but again, if we were relying on bottles more, these could be helpful.” She particularly appreciated the included water softener, which she found useful in her hard-water area.

The eufy S1 Pro comes with a removable water tank, drainage pipe and bottle rack to hold bottles and pump parts in place during washing.

How easy is it to set up and use for the first time?

Holly found the initial setup straightforward. To start, she removed the protective plastic covers, plugged in the machine, secured the hose and added the water softener. Filling the tank was simple thanks to its handle, and adding detergent was easy, too.

The bottles and pump parts fitted neatly inside, and Holly found the controls easy to follow when starting the first wash. The only issue was positioning part of the lid correctly, which caused water to spill during the first wash.

Connecting to the app was also straightforward, with a QR code taking Holly to the correct app and the setup process working smoothly. She found the visual instructions particularly helpful, explaining, “I much prefer a visual one pager than a thick instructions booklet!”

How does the eufy S1 Pro Bottle Washer and Steriliser look?

The eufy S1 Pro has a sleek, modern design that Holly felt looked good in her kitchen. She was impressed by its construction, describing it as premium and well made, with intuitive controls that were easy to understand.

However, it is a fairly bulky appliance, which may be an issue if you have limited worktop space. Holly felt her family didn’t need the extra capacity and would have preferred a smaller machine.

The eufy S1 Pro measures 34.5 × 37.3 × 43.2cm, making it larger than the Bebello 4-in-1 Bottle Washer, which measures 26 × 33 × 41cm. The eufy can wash up to 10 bottles at a time, compared with the Bebello’s eight, so the choice comes down to whether you’d benefit from the extra capacity or prefer a more compact appliance.

What’s it like to use day to day?

Holly found it easy to load the eufy S1 Pro, with the rack holding their bottles and pump parts securely. It can fit up to 10 bottles, or four bottles alongside a full set of breast pump parts, which is a lot of space for a relatively small amount of washing.

As Holly’s son is mostly breastfed, she felt they could have got away with a smaller machine that took up less room on the worktop. For families who use more bottles or express regularly, though, the extra capacity could come in handy.

Holly found the controls easy to use and mostly stuck to the full wash programme, although there are quicker wash options, as well as self-clean and DIY modes. The machine also uses 100°C steam to sterilise bottles, eliminating 99.99% of germs, and its thermal circulation system is designed to keep them sterile for up to 72 hours. With washing, sterilising and drying all handled by one appliance, Holly found it easy enough to keep on top of their daily routine.

The biggest niggle was the water tank. Holly found it awkward to fit under her kitchen tap and putting it back without spilling water was tricky. It also needs to be filled almost to the top for each wash, which made this part of the routine slightly more of a faff than the rest.

The eufy S1 Pro uses high-pressure water jets to wash bottles and pump parts, followed by steam sterilisation and hot-air drying, all in one machine.

How hygienic and safe is the eufy S1 Pro Bottle Washer and Steriliser?

Holly had no concerns about hygiene or safety during testing. As she explains, “It dries and sterilises really well, the bottles smell neutral and come out dry with no condensation. I don’t have any hygiene concerns at all using this washer.”

Holly also found the machine stable on the worktop, with no surfaces getting too hot during use. She had no concerns about its safety and didn’t feel child safety features were necessary for an appliance that could easily be kept out of reach.

How well does it clean bottles and accessories?

Cleaning was one of the eufy S1 Pro’s biggest strengths for Holly. She was particularly impressed by how clean everything looked when it came out, saying, “Everything looks spotless coming out. No stains or white residue (this is the first washer we’ve used where that’s the case!).”

Living in a hard-water area, Holly is used to seeing limescale marks on bottles, but the included water softener made a noticeable difference. She explained, “Almost everything ends up with limescale stains that we wash but thanks to the water softener, not when using this!”

The washer uses high-pressure water jets to clean bottles and accessories from multiple angles, while its different wash programmes offer flexibility depending on what needs cleaning. Holly also liked the reassurance of the multiple wash cycles, saying, “Knowing that there are multiple washing cycles also reassures us that everything’s super clean.”

How fast does the eufy S1 Pro Bottle Washer and Steriliser work?

The full wash programme takes around an hour and a half, which Holly felt was quite a long wait. However, it worked fine for her family, as they didn’t need to wash large numbers of bottles throughout the day.

Holly mostly stuck to the full programme, but there are faster options available when you need clean bottles sooner. If you’re washing lots of bottles and pump parts every day, it’s worth considering how the cycle times will fit around your routine.

How durable is it?

Holly was impressed by the build quality of the eufy S1 Pro and found it sturdy throughout her four weeks of testing. As she put it, “I always feel like I’m operating a high-quality product when using this bottle washer.”

She didn’t have any problems with parts breaking, bending or showing signs of wear during testing, which added to her confidence in its quality.

How does the eufy S1 Pro Bottle Washer and Steriliser compare to other bottle washers?

Having used UV sterilisers in the past, Holly appreciated being able to wash, sterilise and dry bottles in one machine, rather than relying on separate equipment.

She also preferred the eufy to the Momcozy bottle washer her family had tried. In Holly’s experience, the eufy left bottles cleaner, without the residue she’d noticed with the Momcozy. She also preferred its appearance, describing it as sleeker and more high-end.

Is it easy to clean and maintain?

Yes, Holly found the eufy S1 Pro easy to clean, as the main parts can be removed without tools, making them simple to take apart and wash.

For ongoing maintenance, the machine has a self-cleaning mode, and the app can send reminders when it’s time to replace the water softener or filter, helping you keep track of routine upkeep without having to remember it all yourself.

Is it good value for money?

At £399, the eufy S1 Pro is a significant investment, and Holly felt it was more than her family would be willing to spend, particularly as they didn’t need its full capacity. However, she could see why it would be worth the money for families who wash lots of bottles and pump parts every day.

Holly was impressed by the cleaning results, especially the fact that bottles came out spotless, without the white limescale residue she’d experienced with other washers. She also appreciated having washing, sterilising and drying in one machine, along with the included water softener. Combined with the generous capacity, these benefits helped justify the price for families who would use it regularly.

She could also see the app and delayed-start function being useful for parents who rely more heavily on bottles, even though her own family didn’t need them. Ultimately, Holly felt the eufy S1 Pro offered good value if you’ll make full use of its features and capacity. If you only wash a few bottles a day, a smaller, cheaper option may be a better fit.
