Mercury L-17E Lo-Boy: 17" Ultra-Quiet Floor Machine at 175 RPM
The L-17E is the 17" model in the Lo-Boy series โ 99 lbs at 175 RPM, with the gearbox positioned under the apron for noise reduction. At 17", the L-17E is the narrowest floor machine in the Lo-Boy lineup, fitting through access points and service corridors where even the L-19E cannot operate cleanly. Despite the narrow footprint, it carries 99 lbs of machine weight โ meaningfully heavier than standard-duty 17" machines at 85โ95 lbs.
L-17E Motor, Gearbox, and Pad Specifications
Apron size: 17" โ narrowest in the Lo-Boy series; fits through 18" service corridors and narrow equipment aisles
Speed: 175 RPM โ single-speed for scrubbing, stripping, buffing, and bonnet cleaning
Machine weight: 99 lbs โ heavier than a standard 17" machine; lower than the H-17E Hercules (106 lbs) due to the Lo-Boy's acoustic-focused chassis
Motor: 1.5 HP A/C dual-capacitor โ draws 13โ15A; same motor platform as the larger Lo-Boy and Hercules models
Gearbox location: Under the apron โ reduces noise transmission through the handle column
Included accessories: 16" pad driver and 15" rotary brush
Power cord: 50-foot 14/3-gauge safety cord
Wheels: 6" non-marking retractable
Where the L-17E Fits in Occupied-Building Cleaning
The L-17E targets noise-sensitive occupied facilities that also have access constraints preventing the L-19E, L-20E, or L-21E from reaching every zone. Hospitals with narrow patient wing corridors, hotels with tightly spaced room doors, corporate office buildings with dense cubicle aisles, and laboratories with fixed benching all present environments where the 17" footprint is the widest machine that fits. In these zones, a conventional 17" machine at 85โ95 lbs still strips and scrubs, but with less downward force per pass. The L-17E at 99 lbs adds 4โ14 lbs of machine weight over those alternatives, which translates directly to more effective single-pass scrubbing or stripping. If the same facility has open areas where the L-21E or L-20E operates, the L-17E runs at the same motor platform and speed โ finish results match across zones without adjusting technique.
Under-Apron Gearbox at 17" and Noise Reduction Mechanism
The Lo-Boy's gearbox is enclosed within the apron housing rather than mounted in the neck or handle column. In conventional floor machines, the gearbox sits above the pad assembly and vibration from the rotating gear sets couples to the metal handle frame, radiating noise upward and outward. Moving the gearbox below the apron deck eliminates that transmission path: the rotating mass stays enclosed in the lowest part of the machine, and the apron housing absorbs rather than amplifies vibration. At 17" โ the smallest apron size in the Lo-Boy series โ the acoustic enclosure is smaller than in the 19", 20", and 21" models, but the fundamental noise reduction mechanism is the same. For facilities that have tried conventional 17" machines and found the noise unacceptable during occupied hours, the L-17E provides the same pad width at measurably lower operating noise.

How does the L-17E Lo-Boy differ from the H-17E Hercules?
The L-17E weighs 99 lbs with a gearbox positioned under the apron for noise reduction. The H-17E weighs 106 lbs with a conventional gearbox and dual-capacitor A/C motor with triple-planetary transmission for maximum torque. The H-17E delivers 7 more lbs of pad pressure. The L-17E is the choice when daytime cleaning in occupied corridors is the primary requirement and noise is a constraint the Hercules cannot satisfy.
What pad sizes are compatible with the L-17E?
The L-17E includes a 16" pad driver and a 15" rotary brush. Standard 16" floor pads โ black (stripping), green (scrubbing), red (cleaning), white or tan (buffing) โ fit the included pad driver. The 15" brush handles textured tile and grout in the narrow zones where the L-17E is most commonly used.
How does the L-17E compare to the L-19E?
The L-17E weighs 99 lbs with a 17" apron. The L-19E weighs 102 lbs with a 19" apron. Both use the same gearbox-under-apron design and 175 RPM speed. The L-17E has 3 lbs less machine weight but higher pad pressure per square inch on its smaller 16" pad driver. The L-17E fits through access points that the L-19E cannot pass.
What electrical supply does the L-17E require?
The L-17E draws 13โ15A under load. Two 15A circuits are recommended for sustained stripping or scrubbing. Single-circuit operation works for buffing and light maintenance. In narrow service corridors where the L-17E is most often deployed, verify outlet locations and plan cord routing before starting work.
Can the L-17E strip finish in noise-sensitive environments?
Yes, but stripping still requires chemical ventilation regardless of machine noise. The L-17E at 99 lbs and 175 RPM with a black stripping pad and appropriate chemical strips commercial-grade finish effectively. The machine noise is reduced compared to a conventional 17" floor machine, but ventilation and chemical odor management requirements are unchanged.
Is the L-17E suitable for bonnet carpet cleaning in narrow corridors?
Yes. Use a 15" or 16" cotton or microfiber bonnet over the included pad driver. The 99 lb machine weight provides passive pad contact pressure. In narrow carpeted hospital wings or hotel corridors where wider machines must make multiple offset passes, the L-17E completes full-width bonnet runs in a single straight pass.

Located in the Twin Cities in Minnesota, we acquired our Brio Air Filter in mid-late Spring of this year (2023) when pollen count was high and we were beginning to experience the effects of Poor Air Quality Index as a result of smoke particulates from fires in Canada that caused the air in much of Minnesota to become hazy and simply dirty.
It is so easy to share our experience with the Brio Air Filter given how quickly and efficiently it removed pollen, dust, and smoke particles from the environment inside our home. Two people in our home who suffer from pollen-related allergies during the spring immediately experienced easier breathing and elimination of symptoms within the house. With respect to smoke particulates from Canada drifting into our environment, EVERYONE in our home experienced directly improved breathing and smell of the air when entering from outside.
An additional piece of information to account for is that we have always employed high grade furnace filters in our homeโs central HVAC system. With that high grade filtration in place both prior to and after acquiring a Brio home air filter, we all quickly agreed that deploying the Brio in our home made an easily noticeable positive difference in breathing inside our home. Additionally, those of us who clean our home have observed that dust builds up slower on our floors and furniture than before we deployed the Brio unit.
We did note that the Brio is not as quiet as a few other brands/models on the market that we have tried in our home but the efficiency and quality of the filtration, along with the air turnover rate it provides,allows us to locate the Brio unit in central rooms away from the bedrooms. Since we made that change there has been no noise-related effect on our sleep, while the unit maintains the same level of air cleanliness throughout our home.
A last key point to make is how easy the Brio unit is to maintain. The simplicity of the modular construction of the Brio unit makes it very quick and easy to keep the filtration sections clean. We have not yet reached a point of filter replacement but it is obvious to us that the replacement will take a matter of seconds and can be executed by anyone in our home, including our 10-year-old son.
It seems to help reduce my allergy issues. We're glad we bought it. The only problem I had was not seeing any cubic footage recommendations in the online description when purchasing the unit. Bedrooms vary widely in size!!
