The backwasher is mounted on the bathroom wall. The user may either stand or sit (on a chair at an appropriate height) with his back leaning against the washing disk or massaging disk for a back scrub or massage.

        The waterproof design of the backwasher allows user to enjoy back scrub and massage while taking a shower.

        With the waterproof remote control, the user may adjust the backwasher's speed and touch points according to individual needs while the unit is in operation.

        1. Control Panel

        1) Based on statistical analysis of human heights, backwasher has 4 motion ranges pre-programmed, shown in the picture. The control panel has four marked upper points for the motion range: 60, 55, 50, and 45, which the user can choose according to his height. Additionally, the backwasher is pre-programmed with Fixed Points, Free-style Short Range Motion (10cm), 2 Revs (100/min and 70/min), Veer (usually for massage use) to meet individual needs and preferences.

        2) When the upper point of the motion range is selected, the washing or massaging disk will start moving from the user-selected upper point to the preset lower point at 0 (i.e. from 60 to 0; 55 to 0; 50 to 0; or 45 to 0). The user may adjust the lower point if it's too low. Press the selected upper key and the lower point will move upward. It rises 50mm every time the user presses the upper key. It can be raised at a maximum 3 times (for a total of 150mm). The lower point will return to 0 when the upper key is pressed for the 4th time. After the motion range is selected, the memory chip will save the selection. The user only needs to select the upper point next time.

        3) The other 4 function keys (Rev, Veer, Fixture and Short journey)
        Rev: Press this key once, the rev is quick, press again, the rev is slow, and press a third time, the rev is quick again, and so on;
        Veer: Press this key once, it is two-way rotation, press again, it turns to one-way rotation, and press a third time, it is two-way rotation again, and so on;
        Fixed: Press this key once, it is fixed-point operation, press again, it returns to the selected motion range, and press a third time, it is fixed-point again, and so on;
        Short range: Press this key, the motion range is short, press again, it restores to the user-selected motion range, and press a third time, it is short motion range again, and so on.

        You may combine any of these functions.

        2. Washing disk and massaging disk
        A washing disk and a massaging disk are included with the backwasher.

        1) Back scrub
Put the cloth slipcover over the silica gel disk, the steps are:
        a) Put the cloth slipcover over the silica gel disk. Securely close the nylon fastener on the slipcover rim with the nylon fastener on the rubber cap. (Note: keep the rim of the slipcover to the base of the wash disk as tight as possible to prevent the nylon fastener on the silica gel disk from being exposed.)
        b) Insert the covered wash disk into the transmission shaft. (Note: push the disk all the way to the bottom of the shaft)
        c) Press the power button on the control panel to turn on the backwasher. The buzzer beeps once indicating the power is on and the wash disk moves to 60 ready for use. The backwasher will start to operate once the user selects a motion range;
        d) Wet the cloth slipcover and apply shower gel or soap on the surface. The wash disk moves up and down to scrub the user's back when he leans back on the disk. The user can adjust the pressure by moving closer or farther away from the wash disk for enhanced experience. The wash disk can also scrub user's chest, belly, arms and buttocks.

        Two cloth slipcovers are included, one coarse and one smooth to suit individual preference. Take off the slipcover after each use and wash it (cloth slipcover can be purchased at retail).

        2) Massage
Insert the massage disk into the transmission shaft.
        There are 3 magnetic silica gel massage balls attached to the massage disk. Silica gel is harmless for external use; these massage balls are safe to human body. When the massage disk rotates, the 3 silica gel balls also self-rotate against the user's back, press, scrubbing and pinching 50+ muscles and stimulating 150+ major and minor acupuncture points. The permanent magnet inside each massage ball generates more than 2,000GS in its magnetic field. The powerful rotating magnetic field can fully activate subcutaneous tissues, increase blood circulation, relax muscles, slow down skin and muscles aging process, and improve health.

        Warnings:
        a) Under no circumstances should the user stick fingers into the operation channel of the transmission shaft, since the finger(s) may get injured.
        b) Users with long hair must wear shower cap as the wash disk and massage disk may coil the hair

3) Remote control

        To meet individual needs, the backwasher comes with a remote control. The remote control allows the user to change rev or veer (clockwise and counter-clockwise rotation), select fixed points, and run short motion range during operation. The remote control sends out radio signal at all directions, and therefore, the user does not have to aim the remote control at the backwasher.
