Haier SWR-T321 – Plus.Parts® Essentials Set

Haier built the SWR-T321 as a straightforward compact robot designed to handle the day-to-day dust accumulation on hard floors and low-pile carpets. Its cleaning action combines bristleless direct suction with four spinning side brushes, collecting debris from the floor surface and feeding it through the suction inlet into a 0.3-litre bin. A HEPA flat filter between the bin and the motor captures airborne fine particles, completing the cleaning loop. The SWR-T321 runs its best when those parts are in good condition, and its regular maintenance schedule is simple enough: keep the filter clear and the brush arms intact, and the robot will continue doing useful work day after day.

This essentials set provides the replacements for both. It contains Plus.Parts® components matched to the Haier SWR-T321: one HEPA flat filter and four side brush arms. Installation is the same as swapping the originals, no tools, no adjustments, just a direct fit into the existing housing and spindle posts. At the end of a part’s service life, a single order here covers everything that needs replacing.

Filter and brush arm geometry are matched to the SWR series housing dimensions. Reach out if you have questions about this model’s specific variant.
