Apollo View Vamp 8HP Multi-Mode LP/BP/HP Sallen-Key Filter with Tube Saturation & DistortionVAMP is a multi mode analogue filter that gives you low pass, band pass, and high pass responses in 8HP. At its heart lies a classic Sallen Key topology supercharged with real vacuum tube (12AU7) saturation and multiple stages of clipping, letting you move seamlessly from smooth, hi fi filtering to snarling, overdriven character. One half of the tube is used to saturate the input, while the other half powers the resonance feedback path with an MS 20

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.
