HobbyStar 3660 4-pole brushless motor provides increased torque when compared to a standard 3650 while still providing top-end power. Versatile waterproof design allows you to drive in extreme conditions and motor leads come with pre-installed 4.0mm gold-plated bullet plugs for easy, no-soldering connection.

Features:

  • 4-pole motor with 12-slot high-torque design
  • High-purity copper windings maximize efficiency
  • High-RPM ABEC5 oversized bearings
  • Precision balanced rotor for smooth operation and maximum RPM
  • Super-thin (0.2mm) stator laminations 

Voltage recommendations in the table below are guidelines for the voltage you can safely run.  It is still critical that the user monitor motor temps and adjust gearing if necessary, any motor can overheat to the point of destruction if over-geared even when running at or below the rated voltage.

      Incorrect filter size despite listed compatibility
      I bought this kit specifically because the listing clearly states that it is compatible with my Xiaomi robot vacuum. Before purchasing, I double-checked all the specifications. However, when the product arrived, I discovered that the internal filter is smaller than the original one and does not fit correctly. This makes the filter unusable for my vacuum. The seller should update the compatibility information because it is misleading for buyers.

      Great quality dust bags – perfect fit for my eufy robot vacuum!
      Size: C10 / C20 Bags
      These dust bags are exactly what I needed for my eufy Omni C20! They fit perfectly, install easily, and the 3-layer design really does help control dust and odors. The large 3.6L capacity means I don’t have to change them too often, even with daily vacuuming. Great value for the price, and the quality feels just as good as the original eufy bags.

      Fits Eufy Vaccum
      Size: C10 / C20 Bags
      Does fit my basic self emptying Eufy. Have to move it around a bit to get it to recognize the bag, but it does fit!
