Affordable & Reliable Auto Top Off System

  • Redundant, Dual Float Sensors
  • Smart Over-Fill Protection Built-In
  • Intuitive Controller w/ Status Indicator LEDs
  • Ideal for Nano to Mid-Size Tanks
  • Safe for Freshwater or Saltwater Aquariums

 

The N-Fill Auto Top Off (ATO) is a simple, affordable system built specifically for nano to mid-size aquariums. Using dual float sensors and smart overfill protection, it automatically replaces evaporated water with fresh RO/DI so your tank's salinity stays stable day after day. The compact controller, clear status LEDs, and easy setup make it approachable for beginner hobbyists, while still being an ATO experienced reefkeepers can trust. By keeping the water level consistent, the N-Fill helps to reduce stress on fish and corals, improve overall tank stability, and eliminate the need for daily manual top-offs.

Dual Float Sensors

Two independent float switches monitor the same water line. The controller starts a refill whenever either sensor detects low water. Even if one sensor fails, the other still triggers top-offs. This redundancy helps prevent missed refills and provides an extra layer of stability compared to most ATOs on the market.

Smart Overfill Protection

If the pump runs for more than about 90 seconds, the controller pauses filling and triggers an audible alarm with a red status LED. This fail-safe helps prevent overfilling if a float sticks low, flow is restricted, or the reservoir behaves unexpectedly.

Simple On-Board Control Buttons

  • Manual: Hold to run the pump for priming or quick refills, release to stop.
  • Pause: Press once for a 30-minute pause. Ideal for feeding or light maintenance.
  • Stop: Press once to disable automatic filling during major maintenance. Resumes after 24 hours.

LED Status Indicators

  • Power: Controller has power and is ready.
  • Filling: ATO pump is actively running.
  • Status: Off during normal operation, blinking when paused, and solid red during stop mode or overfill alarm

Mop won’t lock and black roller won’t fit
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
We’ve had our E28 for about a year now, so it was time to change out some of the more worn parts. This kit looked to have everything I wanted to swap out. It came with two sets of sweeper brushes, two center brushes, the roller mop brush, two dust bin filters and several disposable dust bags. I was able to get all of the parts to fit on our E28 except the black side main brush. It looks like the diameter of the hole isn’t correct for the model, but the grey side was (see photos and video comparing this set to factory set). The roller mop looked very similar except it had a slightly less high pile. The pieces all seemed good quality over all. Putting the new parts on was easy otherwise and they fit well. I sent out our E28 for a whole house cleaning and it did well both vacuuming and mopping, or at least on-par with the factory parts with the same noise level. The aim issue was that the roller mop wasn’t locking in place, and when it went to try to wash the mop and popped the whole vacuum out of its base cradle and threw an error a couple times throughout the cleaning. I just had to manually push the roller mop back in and it worked fine until the last wash and then I couldn’t get it to stop throwing the error. So, 2/5 stars for the one piece not fitting and the roller mop having issues during the mop washing process. Guess I’ll have to order from Eufy directly.

Direct replacment for omni E28!
Size: Eufy E25 Omni / E28 Omni E28, Size: Eufy E25 Omni / E28 Omni E28
This kit is an excellent value and contains direct replacement parts for the Eufy E28 Omni. Everything in the box from the rolling brush and the roller mop to the filters and dust bags matches the original components perfectly in size and fit. ​I found that the side brushes and the main roller installed easily without any forcing, and the vacuum performance remained consistent with no loss of suction or strange noises. The HEPA filters fit snugly in the housing, and the dust bags slide right into the docking station just like the brand-name ones. It is much more cost-effective to get this entire bundle than to buy these items individually. If you need to refresh your E28 Omni, this set is a reliable way to get it back to peak performance.

Excellent
These cleaning wipes work great for my pick up truck and they leave a new car smell. After you wipe down the surface, it leave's everything looking shiny and new. At this price it’s a very good product.

Nice products with great results
I purchased the Meguiars supreme shine protectant wipes to keep in my car for touch ups when things need a little freshening up. It is easy to use, nothing to spray and keeps my interior looking like new. Nice and black. It also protects my dashboard from the harmful sun rays. It has a pleasant smell as well.

Great product before they dry up
Great smelling product, that performs and protects and a high level. It left my car looking and smelling good with its unique scent and formula. I usually keep these inside my glove box since they’re so compact I can easily get the container and wipe when needed. The wipes retain its moisture fairly decently. I find that if I don’t use all of the wipes within a 2-3 month time frame, they will dry up and be no good. As long as you use them up before that it’s a nice buy for your vehicle.
