Are you shopping on AliExpress for the first time?

The process is via the AliExpress mobile app, where most people shop. There are two key things: don’t use Buy now and enter the coupon only in the order summary, in the field Promo code. After you click Pay now, you won’t be able to add it.

1. Copy the code and click Use discountIn our article, copy the coupon and click the button GET DISCOUNT. The link will take you directly to the product in the AliExpress app.
2. Use Add to cart instead of Buy nowOn the product card, scroll down and tap Add to cart. Don’t use the Buy now button—you’ll skip the cart, and later you won’t have anywhere to enter the coupon. Before that, double-check the variant: the color, the version, and whether it ships from an EU warehouse.
3. Through the cart, go to CheckoutA pop-up will appear: Added to cart! — tap Check it out in it. If it disappeared, open the cart with the icon at the bottom right. In the cart, check the product and quantity, then click the red Checkout. Only the items marked with the red ring will be applied.
4. Enter your address and card, then look for Promo codeIn the order summary, first fill in the delivery address and payment card at the top. Below them there’s a line Promo code — expand it with the arrow on the right.

   

5. Paste the code and confirm ApplyIn the field Promo code paste the copied code and click the black Apply. The code is case-sensitive and must not contain spaces.

   

6. Check the savings and payIn the Summary expand the line Saved — you’ll see the applied coupon there as AliExpress coupons/codes. Only when Total is really lower, click Pay now.

   

Apply the discount already at the order summary. After you click Pay now, you can no longer add a coupon. If Apply shows an error, the code has either expired, doesn’t apply to your items, or the order doesn’t meet the minimum amount.

The Store Coupon also goes in the same field. — a coupon from the seller itself, which isn’t always available and changes from day to day. AliExpress coupons can’t be combined, so try both and go with the one that gives you more. Coins are added automatically.

He’s had it for over two years and it still reliably vacuums!

Our fans also praise this pool vacuum—many of them use it actively for quite a while now. Gabriel said he’s had it at home for more than two years and considers it a perfect helper. In his 3.7-meter pool, you just submerge it and let it work— after just one hour it thoroughly vacuums hair, sand, flakes, and even dust settled on the bottom. Luky added that the vacuum is truly a great helper and vacuums everything nicely. Join our FB page as well, where you can regularly see feedback like this.

Powerful motor and efficient cleaning

The Redkey S100 is equipped with a powerful 28 W motor and a dual suction system that lets it move at speeds up to 56 ft/min (about 17 m/min). The vacuum can be submerged to a depth of up to 3 meters and easily removes various types of dirt, including leaves, sand, smaller particles, and pieces of paper. An ultra-fine 180 μm filter ensures it captures even the smallest particles.

It’s ideal for cleaning pools up to 1000 ft² (approx. 100 m²). For larger areas, cleaning performance and/or operating time may be limiting. It’s designed for pools up to a depth of 3 meters, and the shape doesn’t matter—it handles oval, round, and irregular pools.

Cordless operation and easy controls

Thanks to the integrated 5200 mAh lithium battery, the Redkey S100 can run for up to 130 minutes on a single charge. That means it can even clean a larger pool without needing charging during the cycle. Charging takes about 4 hours. The vacuum has no cables, which reduces the risk of electric shock and also eliminates worries about tangled cords.

Using it is very simple—just press a single button, submerge the device in water, and everything else takes care of itself. When the cycle ends or the battery runs out, the vacuum automatically moves to the edge of the pool, making it much easier to take out using the included hook.

Tech that makes your life easier

The Redkey S100 features so-called intelligent self-parking—if it detects a filter clog, low battery level, or when the cleaning cycle is finished, it automatically stops at the pool edge. Plus, thanks to the simple filter-system design, you can clean it in just a few seconds under running water. The package also includes a charger, a filter, a hook for pulling the vacuum out, and two spare cleaning pads.

The device weighs just a few kilograms, so handling is hassle-free. The battery has a capacity of 57.72 Wh and includes 6 lithium cells with a voltage of 12.8 V, with the total battery weight being only 290 g.
