APOSEN H251 Blue Features and Specifications

APOSEN H251 Blue is designed to be used as a lightweight cordless vacuum cleaner or as a powerful handheld vacuum. Conversion from the stick to the handheld unit and vice versa is done quickly and easily.

As a stick vacuum cleaner, APOSEN H251 Blue weighs only 5.5 pounds (2.5 kg) and may be used easily even by the elderly people.

The unit is rated at 250W, with the power being provided by the 6-cells 22.2V 2200mAh lithium-ion battery.

APOSEN H251 Blue features two suction modes, Normal and Max suction modes.

When the Normal suction mode is used, the unit is able to create 7 kPa of suction and to operate up to 30 minutes on the single battery charge.

When the Maximum suction mode is used, the runtime is shortened down to 12 minutes, but the unit creates 18 kPa of suction, which is a lot - for example, robot vacuum cleaners rarely develop more than 2-3 kPa of suction.


The battery is detachable and if required, one may easily replace it with a new one, or use two or more batteries to prolong the operating time of the vacuum. When the battery is fully discharged, it takes around 4.5 hours to fully charge it. Battery comes with the battery meter, allowing the user to see the amount of the battery charge.

Main cleaner head comes with a 15W motorized brushroll featuring both stiff and soft bristles for improved cleaning effect regardless of the floor type - APOSEN H251 Blue is suitable for cleaning various floor types including carpets, area rugs, bare floors, car interiors, stairs, pet beds, etc. However, on very sensitive bare floors, one should first check the effect of the spinning brushroll on some small area - better safe than sorry.


The main brushroll doesn't feature any hair removal system, but it comes with a brushroll hair removal tool and translucent cover, allowing the user to check the condition of the brushroll.

Note: APOSEN H251 Blue is very simple to use and maintain cordless vacuum, but when it arrives, be sure to read the Owner's Manual and to get accustomed to your new vacuum cleaner.

The main cleaner head also features strong LED headlights, helping the user spot dirt on the various floor types, but also help the user clean in low light conditions, for example, under the beds, sofas and similar.

Thanks to the lightweight design and swivel neck, APOSEN H251 Blue is a very maneuverable unit, being able to easily clean floor surfaces under and around the furniture and other floor objects and obstacles, along the walls, and similar.

The aluminum cleaning wand is telescopic, allowing the user to change the length from 3.7 to 4.65 feet (113 - 142 cm). With such length, it is very easy to reach and clean various surfaces up to the ceiling.

Dirt cup is transparent, allowing the user to see the amount and type of vacuumed dirt. Dirt cup features a bottom emptying system and capacity of 1.2 liters, which is an excellent capacity for such a compact, convertible unit.

Nonetheless, it is highly recommended to empty the dirt cup after each use.

The air filtration system is a combination of cyclonic action and several mechanical air filters.

According to the manufacturer, APOSEN H251 Blue features 4 stages air filtration system: cyclonic action, stainless steel mesh filter, sponge air filter, and HEPA air filter and the unit is able to capture 99.99% of 0.1 microns or larger dust particles.

Air filters are washable, keeping the maintenance costs relatively low - nonetheless, depending on the use and vacuumed dirt, it is recommended to replace air filters every few months.

Note: never operate APOSEN H251 Blue or any other vacuum cleaner with wet/moist air filters or no filter at all - such use may damage the unit and render its two-year limited warranty void.

APOSEN H251 Blue Cleaning Tools and Attachments

To help the users clean elevated surfaces, APOSEN H251 Blue comes with a very usable set of cleaning tools and attachments.

- motorized mini-brushroll head (electric sofa brush) features small brushroll that is very efficient in vacuuming carpeted stairs, pet beds, upholstered surfaces, even smaller carpets.

- round brush features angled neck, helping the user to clean surfaces under an optimum angle, saving time and effort.
