Vacuum Buying Guide __LINK__

I've tried to compile the most comprehensive guide to purchasing a wet/dry stop vacuum.Here you can learn about all of the characteristics of a wet/dry vac that you can search foron this site, and be fully informed so you can search for the perfect wet/dry shop vac to meet your needs.

Vacuums within a brand usually share a common look, including color scheme, and typicallyuse the same filters between different models of similiar sizes. Larger brands likeShop-Vac and Vacmaster have multiple branded series of vacuums, each of which have asimiliar look, function, and features.

This is who actually makes the vacuum. There are fewer manufacturers than there are brands.It's common for different brands produced by the same manufacturer to share the same motors andother components, and just be styled and colored diffently to represent the various brands.

The majority of these vacuums have tanks that are made of plastic, typically polypropylene.Some, however, are made with stainless steel or occassionally other metals. For most purposes, plastictanks are the most practical. They are fairly light, don't dent, don't rust, and are notaffected by most acids or corrosive compounds. There are certain cases, however, wherea metal tank might be preferable. For instance, if you are vacumming hot materials like ash,which could potentially melt or ignite a plastic tank.

Capacity is typically measured in gallons, but there's a catch. It refers to thecapacity of the tank of the vacuum cleaner, if you were to fill it to the top. Ofcourse, there's a filter that has to be in there too, as well as some air spacebeneath the filter. So the actual capacity of how much debris you can hold in thevacuum is substantially less.

Generally, larger vacuums are also more powerful, but they are also usuallyheavier, bulkier, and more expensive. For most people wanting a general purpose vac,the medium sizes work best, between 4 and 12 gallons.

This is the number of sets of fan blades in a vacuum motor. Each set of bladesincreases the vacuum, or speed at which air is pulled through. A two-stage motor is ableto provide a stronger vacuum at the same rotation speed versus a single-stage motor. Or,it can provide the same amount of vacuum as a single-stage motor while rotating moreslowly. This allows it to be quieter, more efficient, and to have a longer service lifethan a single-stage motor.

The maximum instantaneous horsepower of the motor on startup. While this is the mostcommonly used comparison attribute, it's fairly useless. The maximum running horsepowerof most vacuums is nowhere near to this, and higher quality industrial motors will have alower peak horsepower rating than low quality ones, while actualy having higheroutput.

Cubic feet per minute of air. This is the maximum amout of air that can be moved bya vacuum motor at no load (no lift). Longer hoses, accessory tools, or a dirty filterwill reduce this flow, as will picking up anything with the vacuum.Example QueriesCFM of 200+Lift (Sealed Pressure)Lift, or Sealed Pressure (SP), is the maximum inches up a tube a vacuum motor willlift a column of water. At this maximim point, air flow (CFM) is zero. Lift decreases asair flow (CFM) increases. In metric, this is represented as Kilopascals, where 1Kilopascal is equal to 4.01865 inches of water.

Noise level (sound pressure) in decibels. Wet/Dry vacuums are notorious for beingloud. Two-stage motors don't need to turn as fast, so they are generally quieter. Somevacuums have air/noise diffusers which also help, though they can slightly reduceperformance. It's generally best to get a quieter vacuum for general use, unless you'llalready be wearing hearing protection and it really doesn't matter.

Unfortunately, many manufacturers don't publish dB for their vacuums. The modelsthat are published tend to be the quieter ones. I spoke with the Shop-Vac company in2019 to ask about decibel ratings, and they said that they stopped publishing those about4 years ago because of their competitors publishing lower dB numbers, insinuating thatthey were falsifying their tests. It's hard to know what the truth is here--that could wellbe true, or it could be that most Shop-Vac models were just louder. It's a shame thatdata like that is not readily available for most models.

Power cord length in feet: Generally (within reason), if you are moving the vacuum around,a longer cord is better, so that you avoid having to use an extension cord. However, a longercord means more to coil up to put away. If you are looking for a fixed, wall-mountedvacuum, then you just need a cord that reaches to the nearest outlet.

Hose diameter in inches: Thicker hoses will provide better suction for a given vacuum,and will be less likely to get clogged with large debris. However, it's a lot bulkier tostore and to maneuver. Hoses range in size from 1" to 2.5" diameter, with the larger andmore powerful vacuums typically having higher diameter hoses.

This is the maximum number of years that any warranty is valid, thoughsometimes they are quite 'limited'. Some manufacturers have longer warranties onthe motor than the rest of the vacuum. Others have lifetime warranties againstmanufacturing defects, but if your motor wears out in a year you might be out of luck.

Most wet/dry vacuums come with wheels of some sort, unless they are intended to bewall mounted, or else are fairly small vacuums that are easy enough to carry. Most ofthe time, vacs have casters, but sometimes they are attached to a dolly with largerwheels.

Ones with all casters are more maneuverable as they can easily turn in any direction. Theseare best for use on hard, level relatively even surfaces. However casters are small and are notgood if you have to move the vacuum over very rough surfaces, or wheel it across a lawn to dump it, etc.

Ones that have fixed larger wheels (usually two, and the other two are smaller wheels or casters), are a bitharder to drag around on flat surfaces, since the wheels don't change direction as easily. But theyare much easiest to drag over uneven terrain. Some are essentially setup as dollies that the vacuum is mounted on,so that they can be moved around like a hand truck.

Vacuums that are wall-mountable come with brackets for mounting on the wall. There two classes ofwall-mountable vacuums. One type are smaller vacuums with short hoses that are meant to be carried whenused, which include brackets to mount on the wall for storage when not in use. The other type are vacuumsthat are meant to stay on the wall during use to become a sort of centralized vacuum for a space. These havelong, often VERY long hoses, and are intented to be mounted in a gararage, workshop, basement or similiarlocation such that the hose can reach the floors or vehicles that you need to vacuum. These still tend to besmall to medium-sized vacuume, since it would become too cumbersome to take down a very large vacuum from thewall to empty the tank or change the filter bags.

Many vacs, especially larger ones with wheels, have drains so that you empty liquidout without having to lift the vacuum tank. On smaller or wall-mounted units, it makesfar less sense to have a drain. Generally, this is just a drain plug that you can remove toallow the fluid to drain out. Some models have standard garden hose size connectors for drainage,while some other more specialized vacs include actually pumps to pump the fluid out.

Are washable filters available for this vacuum? Having washable (really should be called rinseable) filters cansave you a lot of money versus non-washable ones, especially if you often vacuum upfine particles that will clog a filter, or damp debris that will stick to it. Sometimes "washable"is not a clear-cut term to use. Some filters are super-durable and you can spray them off with a hoseover and over again and be fine. Other can be very gently rinsed without pressure a few times and still used.Both of these types I am classifying as "washable". Some other filters simply can never get wet at all, and as soonas they do, the paper that they are made of will fall apart.

In all cases where you can rinse a filter, you must allow it to fully dry before using it again, or it will not workand you will destroy it. If you are planning on doing that, I would strongly suggest that you make sure you have an extrafilter on hand. That way, you can take one out an rinse it, set it aside to slowly dry, and put your dry filter into your vacuumso that it's ready to use again.

Most wet/dry vacuums come with, or will work with, foam filters. These are always washable, but they are intended forvacuuming liquids, and would do little to filter any particles out of the air. Mostly they just protect the motor fromspinning too fast and from getting dirty liquids spashed into the fan blades.

The vacuum cleaner is an essential cleaning tool for workplaces such as the hospitality industry, offices, shops and factories. In fact, it is used to remove dust and other residues from floors and surfaces, guaranteeing a clean and safe environment.

The professional/industrial vacuum cleaner is comprised of a suction motor connected to a nozzle, by a hose, through which the material is recovered into a collection bag (if applicable) or into the collection tank.

There are various types on the market: dry vacuums, wet & dry vacuums, carpet cleaners, vacuums for special and industrial applications. To make the right purchase, it is important to know what elements need to be considered.

Once your needs have been defined, it is necessary to assess certain technical characteristics to compare the various models. Some of the parameters to take into consideration, in addition to the overall dimensions, weight, practical use, are, for example, motor power, vacuum power performance, noise level and filtration system.

The motor power is expressed in Watts, kW or in HP. It depends on the type and number of motors that the vacuum is equipped with. The choice of number of motors and therefore the power must be proportionate to the application and the amount of material to be vacuumed. 041b061a72
