The Ultenic U11 Pro Cordless Vacuum Cleaner

Over the last two years, I’ve tested and reviewed several cordless vacuums. Three were excellent units, although a bit pricy. The fourth was dirt cheap but failed to clean effectively.

Today I am looking closely at the Ultenic U11 Pro cordless vacuum. It’s a medium-priced cyclonic vacuum that boasts strong suction and features a complete set of useful accessories. At first sight, this device appears to be sturdily built, and I am looking forward to putting it through its paces.

Description

The U11 Pro’s body is composed mainly of gray plastic with green accents. It is 49.4 inches high, 8.72 inches wide, and 10 inches deep when fully assembled.

The package includes a handheld vacuum, powered main brush, powered upholstery brush, round dust brush, crevice tool, and an extension tube. Also provided are a mount, spare HEPA filter, AC adapter, brush cleaning tool, and a user’s guide.

The main module, which can function as a handheld vacuum or as a component of the stick vacuum, is fitted with a clear plastic, 650ml dustbin. The U11 Pro’s 380W motor, powered by a removable 2200mAh lithium battery, delivers up to 25KPa of suction.

Included within the handheld vacuum’s body is a cyclone used to separate the heavier debris and a HEPA filter that removes the dust.

This unit is trigger activated and, to avoid fatigue, remains on until pressed again. A touchscreen displays battery level and selects the degree of suction.

Overview

Traditional vacuum cleaners are designed to pull in dirt and stuff it securely into a bag. Using concepts originated by Bert Kent and Edward Yonkers, James Dyson devised a bagless, cyclonic vacuum suitable for household use. Many manufacturers, impressed by the vacuum’s ability to maintain strong suction as its dustbin fills with debris, have adopted the cyclonic design.

The U11 Pro’s motor produces strong suction, forcing dirt-laden air into a cylindrical dustbin and spinning it around a centrally positioned plastic cyclone.

While larger and heavier dirt particles swirl to the edge, fall downward and collect at the bottom of the bin, the slightly cleaner air is drawn through tiny holes that perforate the silver-colored section of the cyclone.

Most of the remaining particles of dirt spin rapidly within the cyclone until overcome by gravity, they fall to the bottom of the dustbin.

The relatively clean air that results from this process passes through a HEPA filter. Since most of the dirt has already been removed, this filter only marginally impedes airflow through the machine.

The Main Brush

Several easily connected cleaning accessories are shipped with the U11 Pro. To assemble for cleaning a floor, snap the extension tube into place and connect the main brush assembly.

The plastic housing for this powered brush is 9.5 inches in width and incorporates a headlight composed of LEDs. This brush performs well on both hard floors and carpets.

A quick twist of the handheld vacuum forces the brush to smoothly pivot up to 90 degrees to the left or right. Two tiny plastic wheels that function as rollers and a pair of rubber wheels ensure the brush glides smoothly across the floor.

Powered Upholstery Brush

This brush is typically attached to the handheld vacuum’s body. Its 5.75-inch housing can pivot upward and downward, and the quickly rotating brush effectively removes dust and dirt from upholstery.

Crevice Tool

The included crevice tool is one inch across and 10 inches in length. This tool is helpful when tackling tight spots such as between and behind the cushions of a couch.

Round Dust Brush

This non-powered utility brush features a soft round brush that can be rotated. It is useful in small and cramped areas.

The Battery

A 28.8V 2200mAh lithium battery is supplied with this unit. It can be charged by the vacuum’s wall bracket if it is connected to power. The battery may also be removed from the vacuum and charged at any convenient location using its AC adaptor. Charging time is approximately 2.5 hours.

The Filter

This vacuum is equipped with a round HEPA filter and its associated foam prefilter. Like the associated cyclonic components, the filter can be removed and cleaned with water. This filter can capture 99.97% of the dust attempting to pass through it.

Performance

The U11 Pro was designed so that, when fully assembled, the operator’s hands grip the heaviest component. This placement ensures that ceilings and drapes may be vacuumed without excessive fatigue.

Each component of this vacuum snaps securely into place. To disassemble, push the appropriate button and pull the accessory free. The crevice tool and round dust brush do not require and are not fitted with pushbuttons.

During my economy mode tests, this device worked effectively when vacuuming hard floors, maintaining consistent suction for 50 minutes. Operational time increases when using the non-powered utility brushes.

In turbo mode, this vacuum performed well, managing to pull unexpectedly large amounts of dust and debris from my varied selection of carpets. When this mode is selected, the U11 can operate for 13 minutes.

The automatic mode allows the vacuum to determine the amount of suction required. I assume it operates much like my robot vacuum, which routinely increases suction whenever it senses a carpet. When this mode is selected, the vacuum often produces a noise level higher than the economy mode but lower than the turbo mode, suggesting it can choose a suction level midway between the two.

Overall Impression

This vacuum is well built, powerful, and equipped with many useful accessories.

I was particularly impressed by the performance of the vacuum’s cyclonic filtering system. After thoroughly cleaning my house, the device’s dustbin was packed with debris. Despite that, its foam prefilter displayed only a light pattern of dust, and the HEPA filter appeared utterly free of discoloration.

If you are searching for a sturdy cordless vacuum capable of cleaning your entire house, I recommend the Ultenic U11 Pro.
