Review of the Roomie Tec Cordless Stick Vacuum
I’d been busy sanding my dining room floor, readying it for an application of Tung Oil. After I finished, I sucked up the dust with my cordless stick vacuum and discarded the accumulated debris from its dust cup. Then I pulled the main brush and washed it under the sink.
Sadly, in one of my increasingly common senior moments, I had neglected to release the tiny clamp holding the brush securely within its housing. When a cloud of dust emerged from the spinning power brush the next day, I realized that I’d broken its release mechanism.
I checked a few sites but failed to find a website where I could replace the broken brush head. It would be necessary to purchase a new vacuum.
The best cordless vacuum I’ve ever tested was Roborock’s H6. This unit is superbly designed, providing plenty of suction while maintaining an eighty-minute battery life in economy mode. Regrettably, the H6 stick vacuum is priced beyond my reach.
My old Jimmy JV51 was no slouch either. This vacuum survived three years of hard use and, if I hadn’t broken its brush release mechanism, would have continued to soldier on determinedly. I considered purchasing another Jimmy, but I wanted to try something new and less expensive.
I finally settled on Roomie Tec’s Dylon. Throughout the following review, I will note the compromises Roomie Tec has taken, allowing them to offer this vacuum at a price far lower than their competition. Hopefully, this information will enable you to decide whether to purchase this model or choose a more expensive and capable vacuum.
The new vacuum arrived packed securely within a smaller than expected cardboard box. This kit consists of the central unit, powered carpet brush, utility brush/crevice tool, power adaptor, two extensions, and a small wall mount.
The vacuum body weighs in at 2.6 pounds. It is composed of black plastic and fitted with a large plastic dustbin. Unlike most of its competitors, this unit’s dustbin cannot be removed for cleaning.
A 2200 mAh Lithium battery provides enough power to allow the Dylon to create up to 120 air watts of suction power.
This device can be used in either economy or high-power mode. Three LEDs indicate battery life.
Included within the vacuum’s main body is a two-stage filtration system consisting of both a metal/plastic and a HEPA filter.
This unit ships with an easily assembled wall mount that accommodates both the vacuum and the crevice tool accessory.

The Cyclonic Vacuum
During the 1980s, James Dyson, a British engineer, designed a vacuum cleaner that worked more efficiently than prior models, which simply suck in dirt and cram it into a bag.
Using concepts originated by Bert Kent and Edward Yonkers, he constructed a bagless, cyclonic vacuum intended for household use. Because a cyclonic vacuum’s suction does not decrease as its dustbin fills, many manufacturers have adopted this design.
Typically, with this type of device, a powerful motor produces suction, forcing dirt-laden air into a cylindrical dustbin and spinning it around a centrally positioned plastic cyclone.
The larger dirt particles swirl to the edge, fall downward, and collect at the bottom of the bin. Meanwhile, the slightly cleaner air is drawn through tiny holes located within the metal section of the cyclone.
Here, a similar procedure occurs, removing much finer dirt particles.
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 Dylon appears to be a hybrid with its HEPA filter replacing the centrally positioned plastic cyclone. Larger particles swirl around and collect at the bottom of the dustbin, but those small enough to pass through the tiny holes in the metal/plastic filter will cake against the HEPA filter, impeding airflow. This system gets the job done, but sometimes during a cleaning routine, the filter will need to be removed and tapped to shake away debris.
The Main Brush
Various accessories can easily be connected to the vacuum body. To assemble for cleaning a floor, snap the extension poles into place and connect the carpet brush assembly.
The plastic housing for the powered carpet brush is ten inches in width. It can pivot from side to side as well as up and down. Two rollers and a pair of rubber wheels ensure the brush glides smoothly across the floor.
While I found this brush worked well on my wood and tile floors, it is optimized for use on carpets. I was shocked by the amount of cat hair it dug from my bedroom carpet.
This brush is equipped with a series of LEDs that work as a headlight.
Dust Brush/Crevice Tool
The dust brush’s bristles are ideal for vacuuming flat surfaces, and the crevice tool cleans tight spots such as behind a sofa’s cushions. This accessory can easily be converted from a brush to a crevice tool.
With the powered brush attached, this vacuum will work diligently for 23 minutes in economy mode. When set to high power, operating time drops to 13 minutes.
The Dylon functions reasonably well in economy mode, picking up dirt and kitty litter without trouble. I did, however, notice that it sometimes failed to suck up pieces of dry cat food.
It performed impressively on my carpet, pulling vast quantities of cat hair from the surface. Nonetheless, its suction is not sufficient to pick up deeply rooted dirt.
I switched to high power and reran my tests. The vacuum was better able to handle the handful of cat food I dumped on the floor, and the extra suction proved useful while vacuuming the carpet.
When I used my old Jimmy JV51 in high power, it felt like the vacuum was attempting to suck up the flooring. The increase in suction when using the Dylon was noticeable but not near as drastic. This vacuum fails to clean carpets as effectively as the Jimmy, but its operating time in high power is significantly longer.
The quality of components appears to be fair, although I expect the lifespan of this unit will be shorter than that of either the Roborock H6 or the Jimmy JV51.
It was difficult to twist off the plastic/metal filter the first time I attempted to remove it for cleaning. Once I’d finally gotten it off, however, that problem did not reappear. Accessories such as the extensions and brushes fit well and operate correctly.
The main brush can be easily removed from its frame for cleaning.
After each use, the filters should be removed and cleaned. Happily, the HEPA filter can be rinsed in water without any ill effects.
This vacuum is a reasonably good device intended to cope with unexpected spills and to handle areas that cannot be reached by a robotic vacuum.
