Xiaomi Robot Vacuum S40 OV81 Side Brush HEPA Filter Mop Cloth Kit

Keep your Xiaomi Robot Vacuum S40 (OV81) performing at its best with this complete replacement accessory kit. Designed as a perfect fit for the S40 and OV81 models, this set includes a side brush, HEPA filter, and mop cloths — everything you need to maintain peak cleaning performance on both hard floors and carpets.

What's Included

• Side Brush – Sweeps debris from edges, corners, and along skirting boards, channeling dust and dirt into the main suction path for a thorough clean.
• HEPA Filter – Captures fine dust particles and microscopic debris, returning cleaner air to your living space with every pass.
• Mop Cloths – Attach directly to your robot vacuum so it can sweep and mop in a single session, leaving hard floors with a fresh, streak-free finish.

Why Replace Regularly?

Over time, side brushes wear down, filters clog, and mop cloths lose their absorbency — all of which reduce your robot vacuum's efficiency. Swapping in fresh accessories restores suction power, edge-cleaning reach, and mopping effectiveness so your S40 keeps delivering the results you expect.
