Why Cleaning Deerma Filters DX700 — vacuum-proof

In this article, we will discuss how to properly maintain both filters of the model — HEPA-filter and washable pre-filter so that the vacuum cleaner lasts longer than the warranty period.

The manufacturer states that, in compliance with the rules of care DX700 It retains 90 percent of its original power after 3 years of operation, but real tests show that without filter cleaning, it drops to 60 percent within a year. We have collected data from official instructions, user feedback and service centers to compile a universal guide adapted to Russian operating conditions (dust, high humidity, frequent cleaning of animal wool).

What filters are in Xiaomi Deerma DX700 and where they are located

The design of the vacuum cleaner provides two filters, each of which performs its function:

• 🔹 A washable prefilter -- it picks up large particles of dust and debris, it's under a dust container, it's attached to the case on the latches.
• 🔹 HEPA-filter (fine cleaning, class) H12) — It can trap microparticles (up to 0.3 microns), allergens and bacteria, located at the top of the dust collector, under the lid with the inscription "HEPA Filter".

Important: In some modifications DX700 (for example, DX700C Wet cleaning, a third sponge filter is added to protect the engine from moisture, and it is cleaned according to the same scheme as the prefilter, but with a mandatory drying for at least 24 hours.

A tip from service centers: if there are any stains on the filter after drying, wipe it with a dry microfiber wipe, which will speed up the process and prevent moisture from entering the engine during the first cleaning.
