Description
Hotel housekeeping staff lose hours pushing cumbersome service carts and hauling separate upright vacuums down carpeted guest corridors. The Karcher ECO! T11 BP Liner CartVac unites a heavy-duty hospitality service cart with a built-in cordless vacuum system. It pulls 70 CFM airflow and 60 inches of static water lift. Ingesting mop bucket water will short the motor.
The mobile cart base utilizes structural foam polyethylene that resists cracking when colliding with door frames and luggage trucks. Power comes from an on-board 36-volt lithium battery pack driving a 300-watt brushless DC vacuum motor. Suction air draws through an integrated 1.6-gallon dry filter bag before passing through a micro-pore exhaust filter. Large non-marking 8-inch rear transport wheels ride on sealed steel axles to keep push force low on dense commercial carpet.
Hardware Matrix Operational Specs
An integrated cart and vacuum architecture lets housekeepers restock linens, collect trash, and vacuum room carpets in a single pass. A front-mounted flex hose and wand detach from the cart chassis for immediate guest room floor cleaning.
- 36-volt lithium battery system delivers up to 60 minutes of cordless guest room vacuuming.
- 300-watt commercial brushless motor pulls 70 CFM airflow without carbon brush replacement downtime.
- Integrated hospitality cart chassis holds linens, amenities, and waste bags on a single mobile platform.
- 1.6-gallon vacuum collection bag captures multiple room sweepings before requiring bag changes.
- Non-marking 8-inch rear wheels roll over carpet thresholds with minimal physical push force.
- Stretch suction hose and wand extend reach up to 8 feet into guest room corners.
- Commercial multi-surface floor nozzle cleans bare bathroom tile and low-pile corridor carpet.
Dyno Thermal Bench Benchmarks
Direct current sensor testing indicates an 8.2 Amp continuous draw on the 36-volt bus under operational floor tool drag. Brushless motor fan velocity stabilizes at 24500 RPM under typical carpet resistance. Motor casing surface temperatures climb 28 degrees Fahrenheit over ambient room baseline during a complete 60-minute battery drain. Battery pack cell temperature reaches 112 degrees Fahrenheit at cutoff point. Audio meters record a quiet 62 dBA at 5 feet from the cart. Current monitoring circuits shut down motor drive if intake blockages occur.
Field Maintenance Trade Offs
The combined cart and vacuum dimensions demand wide elevator doors and open linen closets for overnight storage. Never task this dry vacuum with bathroom puddle extraction or spilled beverages because moisture rots the filter bag and damages electronic circuit boards. The cart requires two hands for stable steering on ramps.
- Allow the 36-volt lithium battery pack to cool down before placing it on the charging dock.
- Clean wrapped threads and hair from the multi-surface floor tool wheels after each shift.
- Change the 1.6-gallon collection bag once debris reaches the marked fill line to protect suction.
