Building service contractors and in-house facility crews reach for the Mosquito 12G-1202H when a job needs truck-mount style heat but the truck cannot get to the carpet. This is a 12-gallon portable hot-water extractor built around a 2000 watt stainless steel heater and a 120 PSI AquaTec pump, so a two-person crew can walk it into a fourth-floor office suite, plug into two building circuits and pull hot solution through soiled commercial carpet the same afternoon.
The practical benefit is turnaround. Twin 5.7-inch two-stage Ametek vacuum motors recover solution quickly, and faster recovery means less water left in the pile and a shorter window before the space can be re-occupied. On overnight janitorial contracts that is often the whole argument for a portable of this class: the carpet has to be walkable by the time the tenant arrives.
Built for
- Overnight janitorial and BSC contracts in occupied office buildings, where a truck-mount hose run is impractical
- Hotel corridors, guest rooms and conference space cleaned floor by floor
- School and campus corridors, cafeterias and common areas with food and grease soil
- Restoration and property-management crews who need one machine to travel between scattered small sites
- Upholstery and stair work using the dual jet wand, solution and vacuum hose kit sold as item 901-0010
Why the heat and the pressure rating matter
Hot solution does the chemical work that cold water cannot. Grease, body oils and food soil release far more readily at temperature, and the Mosquito heater is not an afterthought bolted to the tank: it is a stainless steel unit with two 1000 watt elements and dual ceramic thermostats. The exclusive DTS Dual Thermostat System, with bimetallic thermal cut-off switches, holds temperature within nine degrees, so the last pass of a long corridor is running at the same temperature as the first.
The 120 PSI rating is a deliberate choice rather than a limitation. Most commercial carpet extraction is done well under 200 PSI, and higher pressure on a soft cut-pile carpet mostly buys over-wetting and longer dry times. A 120 PSI machine paired with real heat is the configuration most crews actually run. If the same crew also cuts grout and hard surface, the 220 PSI 12G-2202H is the sibling to look at.
Operator details that save time on site
Every gauge and control sits on one panel, so the operator is not walking around the machine mid-job. A single valve rinses the recovery tank or drains the solution tank. Another valve primes the pump. The cord wrap is quick release. The vacuum stand tubes are molded in rather than bolted on, which removes a routine maintenance point. A recovery tank full indicator light and automatic motor shut-off protect the vacuums, and the motors carry thermal protection that shuts them down and lets them restart after cooling.

Frequently asked questions
Does the 2000 watt heater need a second outlet?
Yes. The heated 12-gallon Mosquito draws on two circuits, and the machine ships with a dual-circuit light and sound indicator so the operator can confirm both cords are live before starting. Plan on two separate 15-amp building circuits rather than two outlets on the same breaker.
What is the difference between the 12G-1202H and the 12G-2202H?
Pump pressure. The 12G-1202H runs an AquaTec pump rated to 120 PSI, which suits routine carpet and upholstery extraction. The 12G-2202H runs to 220 PSI for denser commercial glue-down carpet and hard-surface work. Tank capacity, vacuum motors and the heater are otherwise the same.
How does the machine stop the recovery tank from overflowing into the motors?
A recovery tank full indicator light warns the operator, and an automatic motor shut-off cuts the vacuums before liquid reaches the inlet. The motors are also thermally protected and will shut down and restart once cool if they exceed working temperature.
Is heat worth the extra cost on commercial carpet?
On greasy or heavily soiled commercial carpet, yes. Hot solution breaks down oils and food soils that cold water leaves behind, which is why cafeteria, lobby and corridor work is the common case for a heated unit. On clean residential carpet the difference is smaller.
What does the warranty cover?
Mosquito covers the body for the life of the machine and the motor and pump for one year. The units are designed, manufactured and assembled in the United States.
