A retractable hose central vacuum stores the hose inside the 2 in pipe behind each inlet. You pull out the length you need, lock it, vacuum, unlock, and the power unit’s own suction pulls the hose back into the wall. Hide-A-Hose is the best-known system and is now part of the same company as MD Manufacturing. The convenience is real: nothing to carry, nothing to store, one inlet covering most of a floor. The costs are a pipe layout designed around hose storage, a premium price, and somewhat less airflow at the tool than a standard short hose. This guide explains how it works, what it demands of the pipe, and whether it can go into an existing home.
How the hose is stored in the pipe
Behind a retractable inlet is a straight-as-possible run of 2 in pipe at least as long as the hose, with large-radius fittings, that serves as the hose’s garage. The hose’s far end stays in the pipe; the near end has a cuff that seats at the inlet. When you pull hose out, the far end travels toward the inlet through the storage pipe. When you release the lock with the unit running, air flowing into the pipe drags the hose back the way it came. The storage pipe joins the system’s trunk through a sweep tee beyond the hose’s parked end, so when the hose is fully retracted, air still flows past it to the unit.
Inlet valve requirements
The inlet is a different part from a standard inlet: a deeper valve body with the lock mechanism, a door that seals around the hose cuff, and a mounting that lets the hose enter the pipe at a straight angle. Mounting height is set by the pipe direction: the manufacturer describes chest-high mounting where the hose runs up into the attic and thigh-high where it runs down toward a crawlspace or basement. A standard inlet cannot be converted to a retractable one by changing the cover; the valve body and the pipe behind it are both different. The door must be closed with the lock released, or it will not seat.
Pipe routing constraints
The storage pipe is designed around the hose. In practice that means:
- A pipe run behind each inlet at least as long as the hose, so a 50 ft hose needs 50 ft or more of pipe before the sweep tee that joins the trunk.
- Large-radius bends only, and as few as possible. The manufacturer’s kits include its own long-radius 90s and 22.5-degree fittings for the storage run, with standard sweep 90s and 45s used only beyond the hose’s parked position.
- No short 90s anywhere the hose travels.
- The tee to the trunk placed beyond the hose’s parked end, not within the storage run.
- Enough attic or crawlspace length to lay the run out; a storage run has to go somewhere, and in a small house that can be the limiting factor.
Standard inlets in the same system use ordinary fittings and rules; the pipe and fittings guide covers those. Follow the manufacturer’s current installation guide for exact bend limits and fitting counts, because they change with the hose design.
Hose lengths and coverage
| Hose length | Approximate floor covered per inlet (manufacturer’s range) | Where it fits |
|---|---|---|
| 30 ft | Lower end of roughly 900 to 2,300 sq ft | Compact floors, upper stories |
| 40 ft | Middle of the range | Typical main floor |
| 50 ft | Upper range | Large open floor plans |
| 60 ft | Top of the range | Very large floors; needs a long storage run |
Hide-A-Hose states that one inlet covers about 900 to 2,300 sq ft depending on hose length. A standard system with a 30 ft hose plans roughly one inlet per 600 to 1,000 sq ft, so a retractable system typically needs a third to a half as many inlets. Count by walking the house with a rope, as in the inlet planning guide, because the hose still has to go around furniture and up stairs.
Suction trade-offs
The hose that slides inside a 2 in pipe has to be smaller and smoother outside than a standard hose, and it is always its full length in the airstream even when only 10 ft is out in the room. Both cost airflow at the tool compared with a standard 30 ft hose on the same unit. Manufacturers address this by pairing retractable systems with stronger power units and by rating each unit for a maximum number of retractable inlets. For bare floors, area rugs, and an air-driven turbine head on medium carpet, most owners do not notice. For deep carpet where you would otherwise run an electric powerhead, look closely at the unit pairing. The air watts guide explains what to compare.
Retractable hoses do not carry 120V for a corded powerhead; the usual pairing is an air-driven turbine head and a handle that switches the unit by RF remote.
Can it be retrofitted?
Yes, where there is an attic or crawlspace to lay the storage run. The manufacturer describes retrofits as typically a one-day job with no drywall repair, and says existing standard systems can be converted by adding retractable inlets and their pipe. The constraints are the same as any retrofit, with one addition: the storage run needs length and gentle bends, so a small attic broken up by trusses or a tight crawlspace may limit the hose length you can use. Slab homes with no attic are the hard case, as always. If you are building, decide before the rough-in; the rough-in guide explains why.
Parts that wear
| Part | How it wears | What to do |
|---|---|---|
| The hose | Slides against pipe every use; cuffs and the outer skin wear | Replaced through the inlet; no wall work |
| Inlet door and seal | Seal flattens; door may not seat | Replace the door or seal assembly |
| Lock mechanism | Spring and catch wear | Replace the inlet trim or valve |
| RF handle | Coin-cell batteries run down; may need reprogramming | Replace batteries per the manual |
| Storage pipe | Rarely; the hose polishes it | Check for a crack if the hose starts to hang up |
A hose that pops the door open or falls out of the wall, or that no longer retracts fully, is the manufacturer’s stated signal to call the dealer.
Common mistakes
- Roughing in standard inlets, then deciding on retractable after drywall.
- Too little attic length for the hose chosen.
- A short 90 in the storage run.
- Pairing a 60 ft hose with a unit rated for fewer retractable inlets than installed.
- Closing the door with the lock engaged.
- Running the unit without its bag or filter because the hose made everything else feel maintenance-free.
What to do next
If you are planning a system, walk the house and decide which floors get retractable inlets using the inlet planning guide, then pick a unit rated for that many retractable inlets with the buying guide.

Frequently asked questions
How does a retractable central vacuum hose work?
The hose is stored inside the 2 in pipe behind the inlet. You open the inlet door, pull out as much hose as you need, engage a lock at the inlet so it stays out, attach the handle and tool, and vacuum. When you finish, remove the tool, release the lock, and the power unit's suction draws the hose back into the pipe; you control the speed by covering the hose end with your hand.
How long is a Hide-A-Hose hose?
Hide-A-Hose offers 30, 40, 50, and 60 ft hoses, and the manufacturer says one inlet covers roughly 900 to 2,300 sq ft depending on the length. A 50 ft hose from a central inlet can cover most of a floor, which is why retractable systems use far fewer inlets than standard ones.
Can Hide-A-Hose be added to an existing home?
Yes, where there is attic or crawlspace access to run the storage pipe. The manufacturer says retrofits typically take about a day and usually need no drywall repair. Existing standard systems can be converted by adding retractable inlets and the pipe behind them. Slab homes with no attic are the hard case, as with any retrofit.
Does a retractable hose have less suction?
At the tool, usually yes compared with a standard 30 ft hose, because the retractable hose is longer, thinner-walled so it can slide inside the pipe, and the air has to travel the full hose length even when only 10 ft is pulled out. Manufacturers pair the system with stronger power units and rate units by how many retractable inlets they can serve. For most homes the convenience outweighs the difference; for heavy carpet with an electric powerhead, check the pairing.
Can I use an electric powerhead with a retractable hose?
Retractable hoses do not carry 120V, so a corded electric powerhead is not the usual pairing. The standard setup is an air-driven turbine head or a handle with a battery-powered or RF switch. Some handles are RF remotes that turn the unit on and off; those take small coin-cell batteries that need replacing.
How high is a retractable hose inlet mounted?
Higher than a standard inlet. The manufacturer describes chest-high or thigh-high mounting depending on whether the hose runs up into the pipe or down from it, because the hose needs to feed straight into the storage pipe. The installer sets the height from the pipe route, not from the receptacle height standard inlets use.
What wears out on a retractable hose system?
The hose itself, which slides against pipe walls every use; the inlet door and its seal; the lock mechanism; and the RF handle's batteries. Hoses are replaceable through the inlet without opening the wall. A hose that no longer retracts fully or pops the door open is the usual sign that something needs attention.
