Compared to a Regular Squeegee: Better and Worse
on February 4, 2013
Honestly, this thing works quite well, and it's almost fun to use. I've cleaned about 25 large windows, and I'm having an argument with myself. Most "infomercial" type specialty gadgets end up in a forgotten corner of the closet. But I'm not sure about this. It's a beautifully designed and manufactured piece of cleaning equipment that works very well, but has its minor hassles.
This is a way to use the excellent squeegee method of window cleaning in places where the flood of dirty slobber from a normal squeegee would be ruinous. Indoor window & mirror cleaning...some of your outdoor window cleaning...some of your car window cleaning. Most helpful if you do a lot of windows at once.
When the novelty factor wears off, you might use it for 40% of your window cleaning. Or 70%, or 0%. Honestly, I'm not sure where I'll end up. 4-stars or 2-stars?
The squeegee method (vac or manual) is faster, easier, and uses way less rags/towels.
1. You still have to scrub any stubborn spots by hand.
2. You still have to touch up some edges with a quick wipe.
3. Bits of Windex spray out the exhaust vents. (see Note 1)
4. Try to keep it upright. Sideways squeegee action makes the spray-exhaust worse.
5. You need to rinse out the Karcher when you're done (less than 90 seconds, with practice).
If you double-team it -- one person with Karcher, one person follows with a rag for stubborn spots and final clean-up -- you could to do a dozen large windows very quickly...under a minute each. In either case, I start with the Karcher, which removes 99% of the dirt. Stubborn spots then stand out, and can be easily worked with a scrubber or coarse rag.
- It works quite well
- Better than using rags/towels but only sometimes better than a regular squeegee
- Rubber squeegee blade is top quality. Wipes very clean.
- Windex run-off does not flood the window sill, track, or wall below
- Fewer side-streaks than a regular squeegee
- Quality plastics, excellent fit, durable look & feel
- Li-Ion battery gives 20 minutes between charges (see Note 2)
- Ergonomic, lightweight, stands on end
- Excellent all-around design
- Quiet enough...Not annoying
- User manual is helpful (but has some silly warnings. See Note 3)
- Indicator light shows when charging is done
- Windex sprays out the exhaust ports. This is its biggest design flaw. (see Tips and Note 1)
- You have to clean & recharge it each time.
- Power adapter wastes 2.1 watts while idle (see Note 4)
- Limited life - Replacement battery not currently available (see Note 5)
- Proprietary squeegee blade (replacement hassle & expense)
- - - Size & Weight - - -
- 14" tall, blade is 11" wide
- 1.6 lbs

Vent diaper: I solved the drool/spray problem by sliding an old sock over the vents. See posted photo. Pen caps ensure air flow is not hampered.
- - - Notes - - -
Note 1: Exhaust Spray - The manual's solution for this is to "empty the dirt water reservoir." But this problem starts after 2 or 3 windows...when the reservoir is 10-15% full. Even if you keep the vac upright at all times. The spray is a combination of mist and droplets, which gets on the windows and potentially on furniture, etc. Plus, small amounts of aerated Windex drip off the bottom of the Vac. See "vent diaper" tip above.
Note 2: 20 minutes between charges - At about 20 seconds per large window, that's enough for 60 large windows.
Note 3: Owner Manual - Available for download...Tries to be very helpful...Lots of specs...Favorite silly warning: "Do not use outdoors or on wet surfaces." Really?
Note 4: Power adapter wastes 2.1 watts while idle. (2.4 watts if attached to the vac.) That's $2 - 6 a year, if you leave it plugged in all the time. Seems like small change, but you have 5-15 of these wall warts in your home (over a billion in the US). Most of today's transformer plugs are smarter than this.
Note 5: Replacement battery is not on Karcher's extensive parts replacement list.
