7-Stage Filtration System

This innovative 7-stage filtration system is designed to capture even finest particles while anti-bacterial and deodorant effects work to clean exhaust air.

Nano Technology

This is a cutting-edge technology that uses a TiO₂ catalyst to provide powerful deodorizing effect. Nano Titanium particles are incredibly small (about 5 nm). Filter of Hitachi vacuum cleaners are packed with these minute particles to firmly catch and resolve odors.

Cyclone Type Features

*Below explanation is focused mainly on CV-SJ21V model

High Power 1800-2300W^*1Motor

The high power motor creates enough force to suck up even the finest particles of dust and dirt from corners and under furniture. And the cyclonic effect of centrifugal airflow separates dust and dirt particles to compress them more compactly.

*1 Wattage differs depending on the model. Please refer to the specifications.

Hitachi's Cyclone type Vacuum cleaner was awarded the Allergy UK Seal of Approval in recognition of it's proven ability to reduce exposure to allergens.

Handy & Easy Remote Control (Infrared Remote Control) Variable Power Settings

Grip Handle with Power Settings

Infrared remote control lets you easily switch between HIGH/MEDIUM/LOW power at just the right time when cleaning. For example, when there's a lot of dirt, you can instantly switch to HIGH for more cleaning power. You can also immediately switch power off if items other than dirt are sucked in. Another advantage of infrared remote control is that you don't have to keep reaching for the main unit so cleaning is easier than ever.

Twin Light Emission System

How it Works

Optical signals transmitted from light emitter ① reach the cleaner after being reflected off the ceiling. Even in a room with a high or vaulted ceiling, thanks to the twin light emission system, optical signals for operation mode switching can still be received from light emiter ②. To enable regular confirmation of battery power, there's a battery checker. And even if the batteries run out of power, you can still use the ON/OFF switch on the main unit.

Easy Dust Disposal

Dust compression technology works compressing dust by 50%. Even if capacity of a dust case is 1.6 L, it can hold 3.2 L of dust.

With easy one-touch operation your hands stay clean even after dust removal. As dust is compressed, it can be removed with minimal dust flying.

Multi Angle Head

While checking how much dirt there is, you can easily adjust power to throughly clean narrow spaces.

You can adjust power to continue cleaning even when there's a rug on the floor.

You can immediately switch power off if something other than dirt is sucked in.

You can control power with one hand while moving things that are in the way.
